Production Phase

HMT24

First of all, happy new year!

This will be the year that we, the TU Delft Hydro Motion Team of 2024, cross the rough waters of the north sea between the Netherlands and the United Kingdom and we are extremely excited about the challenge.

However, we have a bit of a journey ahead of us before we hit those waves. Rounding up the detailed design phase marked a milestone for our team as we could finally share our newest design with the world. Now, as we transition into the production phase, everything that was designed gets to come to life! Let’s delve into the latest updates and developments of each department.

HULL & BODY

Our five Hull and Body engineers have already been producing for about three weeks at Contest Yachts in Medemblik and plan to be there for about eight more. Just like in the past couple of years we are using carbon vacuum infusion to produce our hull. What is different however, is that due to the size of our boat design, we're using a split-mould from Nedcam instead of a direct mould. Aligning the two sides carefully is therefore crucial since we require the mould to be vacuum-tight. Managing this task becomes quite a challenge with the mould dimensions at 8.5 metres by 3.2 metres.

In recent weeks, their focus has been on preparing the mould, consisting of activities such as waxing, fitting inserts, and creating plates for the deck and bulkheads. These preparations set the stage for the upcoming weeks.

Looking ahead, our Hull and Body department will continue with the production of the hull and deck, laying down the foundation for the project.

EMBEDDED SYSTEMS

In recent weeks, the Embedded Systems department has been busy designing the electrical systems that enable the boat to sail and fly. They have determined the placement of cables, components, and electrical boxes.

Subsequently, they have been actively involved in designing PCBs and writing software to integrate all components and are also engaged in constructing a new high-voltage battery. They will start assembling and testing the battery at IONBASE in Muiden coming week. While continuing writing software and building the complete electrical system for when the boat arrives from production in Medemblik.

VEHICLE DYNAMICS

The Vehicle Dynamics departments’ production phase doesn’t align perfectly with the other departments, but they have definitely not been sitting still. Faced with the need to work extensively with previously unfamiliar machines, such as CNC and milling machines, the department has dedicated their time to following various courses and becoming experts at them. At the same time, they have been creating all the designs for the parts, getting ready for production.

This will allow them to start producing a lot of parts in the coming weeks. Parts they produce are for example the steering and foil actuation as well as the sleeves, which connect the struts with the hull. Then in March they will start the production of another extremely important thing, the foils. The department is going to produce these at Qconcepts this year.

OPERATIONS

With the Design Presentation just behind us the Operations department is already shifting its focus to the next big event, the reveal of the boat! This will take place in spring and the department will work on preparing this event in the coming weeks. Next to the big event there are also several partner related events that they are focussing on.

Besides event planning the department is busy with designing the wrap of the boat. This will be done in collaboration with the team through brainstorm sessions and opportunities to voice their opinions.

The New Hydro Motion Team

Last August, we had the honour of taking over the Hydro Motion Project, thereby becoming the 2024 Hydro Motion Team. We are a brand new team of 23 multidisciplinary students who are dedicating a full year towards designing, producing, testing and sailing a flying hydrogen-powered boat!

These last few months we have been very busy starting up with our team, setting our goals for this year, and designing our boat! We are currently nearing the end of our design phase, with production starting off in december. This is all to reach our scope:

“In one year, we will design, build and test a hydrogen-powered boat and sail between the Netherlands and the United Kingdom”

We started this year by revealing ourselves and our goals in the “Team & Scope Reveal” video, which you can watch here:

Team & Scope Reveal

Design Process

Our design process involves three different stages: Top Level Concept, Sub Level Concept, and Detailed Design. We're currently in the final Detailed Design phase, meaning that the finishing touches are being placed on the design of our boat. However, before reaching this phase, we first completed the top and sub level concept phases.

During the top level concept we determined the internal and external constraints of our design. We asked ourselves questions such as “In what conditions do we need to be able to foil?”, “What are the necessary measurements of our boat?” and “What will our propulsion system look like?”. Answering these questions, and many more, lead us to making the biggest decisions regarding the design of our boat. Following this phase we went more in depth, which also involved dividing our team’s engineers into three different departments:

Hull & Body - Responsible for the design and production of the hull, and internal architecture of the boat. Additionally, they design the hydrogen systems, ensure structural integrity in the boat, and manage the weight distribution of all systems.

Vehicle Dynamics - Ensures proper function of all moving parts in the boat. This department is responsible for the struts and foils, as well as the steering and cooling systems. The Vehicle Dynamics department sees to it that our boat will be able to fly above the water!

Embedded Systems - Takes charge in all electronic and technical systems. These engineers are involved in connecting all sensors and systems, and making sure they work together seamlessly. Beyond internal coordination of all systems, they also ensure effective communication between the boat, safety vessels, and the mainland.

Besides the engineering departments there is also the Operations Department; they are responsible for marketing and all communication to the outside world, and Management; who facilitate the team to be able to reach their goals. For a more in depth look into our different departments you can find the department reveals on our instagram page!

Speed Challenge

Today was our last racing day.We started the day full of confidence having scored second place in the Manoeuvrability Challenge and first place in the Endurance Challenge. The upcoming Speed Challenge was very important to us because we could finally show the potential of hydrogen to the world. We knew that we had fierce competition as our competitors with their battery-powered boats can achieve high speeds. This made it a challenging and exciting day. We started the day with a good feeling, because we were very happy with the results of the previous days and we were confident about this race.

Yesterday we experienced for the first time how rough the Open Sea can be. From the start of the race today, we noticed the waves hitting the boat and flooding the deck. It was very difficult to handle these rough conditions. In the beginning we were close to our competitors and we immediately tried to foil above the waves. Due to the big waves a lot of water entered the boat, causing technical difficulties. We investigated the problem and tried to fix it on sea. However, the waves were too high to safely perform maintenance and the decision was made to tow Aurora back to the harbour. In the harbour the whole team rushed together to fix the boat and so we could sail again.

After consulting with the race organisation, we decided to stay in the harbour to guarantee the safety of our boat and the pilots. Our strategy crew was confident that we would stay ahead of our competitors thanks to the amazing results of the previous days. We became world champions in the Monaco Energy Boat Challenge! We are extremely proud of what we have accomplished here in Monaco. We sailed efficiently on hydrogen and we foiled stably on the Mediterranean waves. We showed that by working together in a high-performing team you can build a fully functioning boat in just one year, because only together we can turn the tide.

Back to Delft

After our final race, the Speed Challenge, our journey in the Monaco Energy Boat Challenge 2023 has come to an end.
In the evening we attended the prize ceremony as World Champions! A title we are extremely proud of to take back to Delft. After celebrating our results we’ll pack everything back up. In the coming days we will be driving back to Delft where we’ll tidy up and prepare the handover for next year’s team. After that it is time to relax, reflect and recover from this year of hard work and amazing experiences. We can look back full of pride on the wonderful year we have had.

Endurance Challenge

Today was our second and most important challenge; the Endurance Challenge. This challenge gave us the opportunity to show the true potential of hydrogen in the maritime industry. For the Endurance Challenge we had four hours to sail as many nautical miles as possible. We sailed the distance in laps, and the boat that completed the most laps wins! For us the trick was to balance the speed with energy consumption. We needed to sail as fast as possible while keeping an eye on the amount of energy we consumed. We had an advantage over the other energy sources because hydrogen has a high energy density. It can therefore carry a lot of energy at a lower weight compared to other fuels. And because we have such an advantage over the other teams we didn't need to sail at full speed so that we have more hydrogen left for the speed challenge.
We were in the lead from the start and really showed why hydrogen is better for endurance than batteries. Unfortunately, about 2;45h into the race the wind started to pick up, creating big waves. We decided to go back to the harbour early to eliminate any risks for our pilots and Aurora. Luckily we already had such a lead that we still finished in first place! The number two did choose to sail the whole four hours but they did not manage to overtake us. This win is a big step towards the World Championship.

Speed Challenge

Tomorrow, we're gearing up for the Speed Challenge! We will sail back and forth to Ventimiglia, an Italian city located 8 nautical miles away. In total we’ll sail 16 nautical miles, equivalent to approximately 26 kilometres. The objective is simple: the fastest boat wins. Thanks to our foils, which reduce drag and enable us to glide over the water, we can achieve speeds of up to 50 km/h compared to the 35 km/h we would be sailing without foils.

Manoeuvrability Challenge

After Aurora arrived on Monday, we had a technical inspection on Tuesday which we passed with flying colours. We had time to test the boat in the harbour for the Manoeuvrability Challenge and we sailed on Open Sea where we almost immediatly foiled!

Today we started the race day with a parade. All the boats participating in the various competition classes could be admired sailing in the harbour. It was an impressive and cheerful parade of solar, hydrogen and battery boats. We are happy to set an example for the maritime industry together. After the parade it was time for our first challenge; the Manoeuvrability Challenge. In this challenge we were tested on our ability to make specific manoeuvres in the harbour.  The manoeuvres we had to perform were sailing around a buoy, slalom around buoys and complete a 360 degrees turn backwards around a buoy and end with sailing backwards and docking the boat. We had to complete te course as fast as possible at a speed of max 4 knots. After talking through our strategy for the challenge we could start our first attempt and we finished with a time of 3 minutes and 9 seconds. This resulted in us winning the second place in the Manoeuvrability Challenge, but this is just beginning.

Upcoming Challenges

On the 7th of July we will have our second and most important challenge: the Endurance Challenge. Here we will demonstrate the true potential of hydrogen.
For this challenge we sail for 4 hours straight. The boat completing the most laps wins! The difficulty here is to balance speed with energy consumption. You want to sail as fast as possible, but by doing so you consume more energy and the amount of energy is not infinite. Hydrogen has a huge advantage over other energy sources as it has a high energy density and can therefore provide a lot of energy with less weight.

On the 8th of July we will have the last challenge; the Speed Challenge. For the Speed Challenge we sail to the Italian city of Ventimiglia, which is 16 nautical miles away, a distance of almost 26 kilometres. The fastest boat wins! Our foils make our boat more efficient by reducing the amount of drag by flying over the water. With the same power we can go from 35 km/h to 50 km/h just by foiling.

June - A foiling hydrogen-powered boat

Over the past few weeks, we have made our first metres with Aurora. She planes very stable and you can see the effect of the chine beautifully. The spray is immediately directed downwards and generates a lot of lift. To maximise the testing time with Aurora, we work in different shifts. In the past month, we tested the hydrogen systems on full power. After a couple of tries the system was reliable enough to start testing with high speed tests on the water. Aurora sails exceptionally stable, especially when planing. This enabled us to sail safely at a top speed of 42 km/h!

Height control

After those tests, we could start with the height control tests. This is the most exciting but also the most tricky part of testing since every part needs to work together seamlessly. The electrical system must be trustworthy, as well as the foil actuation (and other) software. Mechanically the hull, foil actuation system and struts must withstand all the hydrostatic and -dynamic forces when foiling. Because there are waves we need to adjust the angle of our hydrofoils to keep sailing stably. We have implemented a PID controller which needs to be tuned, we do this ourselves. The PID is like the settings of a computer, we have to alter the settings till the system doesn't over or under react. So by tuning the parameters for height, pitch (rotational motion around the side-to-side axis) and roll (rotational motion around the longitudinal axis) we are creating a stable foiling hydrogen-powered boat.

Friday the 2nd of June marked a significant moment for our team as we embarked on testing our height control system. During our height control testing, we achieved a remarkable milestone as we successfully foiled for the first time! We worked really hard to make this happen and we couldn't be more proud that we achieved part of our goal by building a foiling hydrogen-powered boat. However, this thrilling moment transitioned into a challenging situation when unstable behaviour of the boat led to damage. The boat stayed afloat, allowing us to safely lift it out of the water. Thanks to the pro-active responses of the team members no one got hurt. 

 

Foiling
20230623_211340

Of course, this recent situation was a setback for our entire team. It was terrible to see our boat, which we had worked on so hard over the past year, get damaged. Despite this, we were not going to give up. We, as a team, immediately started planning the repair, and we are confident in our ability to overcome and emerge stronger than ever! The whole team worked very hard to repair everything that was damaged, and in just 10 days we were able to get back to testing again! 

 

During the last two weeks we have worked diligently to restore the functionality of the system after the incident. Some parts broke down, and everything had to be thoroughly tested again to ensure the reliability of the components. The buffer was revised to make it more robust.

We also conducted some tests for the height control and there were significant changes made to the code based on the results. The display of the pilot is also updated to provide more informative feedback and the steering mechanism is improved so the pilot can handle the height control of the boat easier.

Monaco

Besides sailing in Aurora, our trip to Monaco is also getting closer and closer. The hotels for the trip have been booked and we are staying near the port. Over the next two weeks, we will be preparing the finishing touches of the logistics for our trip and our stay in Monaco. That way, we will arrive at the start fully ready for what’s to come.

We are in good spirits for the Monaco Energy Boat Challenge and are looking forward to competing in the Open Sea Class. The first challenge we have to complete in Monaco is the manoeuvrability challenge. For this part we’ll need to complete a certain route as fast as possible with a maximum speed of 3 knots which is about 5,5 km/h. Because there is a maximum speed it is all about the pilot’s and the boat’s manoeuvring ability. 

The second challenge we’ll face is the endurance challenge. This challenge allows us to really show the potential of hydrogen and the difference between hydrogen and battery powered boats. All boats will get four hours to cover as much distance as possible. Because batteries are so much heavier than hydrogen, we can take more energy with us and therefore sail further. 

The last challenge is the speed challenge, this will be intriguing because batteries can release more energy in a short time compared to hydrogen. This means that we’ll need to foil to improve our chance of winning. Monaco is approaching very fast so at the moment we are on the end sprint and working hard to get the best out of the boat.

May - Testing

During the last few weeks we have been busy with testing our boat in the water, and we also had our boat reveal!

Hull and Body

In the Production & Assembly phase, the entire hull with all interior and exterior parts was completed. Furthermore, the hydrogen system was pressure-tested and the tanks were filled with hydrogen for the first time. Now, testing the fuel cell could finally begin. After several tests on dry land next to the Dream Hall, we could test the fuel cell with a sailing boat.
A lot of tests were promising and we had to work on some parts of the boat to make it work. In the next few weeks we will see the boat tested to its limits.

During testing, the roles in the team changed. The Hull & Body Department deals a lot with the logistics for our race in Monaco. The first steps have been taken by arranging a sleeping place in Monaco. They are now working hard to be able to transport the entire team, our entire workshop, the RIB and our boat Aurora to Monaco.

Embedded Systems

These times are very busy for the Embedded Systems department. They are present at the testing site in Drimmelen almost every day, because they need to test our electrical systems, and adjust our software and hardware until we have a perfectly working boat. This process is as follows: they do a test in the water with the boat, while carefully looking at all data from our systems and sensors. This data is also saved on a server in the cloud, so that we can analyse it after the test. The last few weeks we were busy with the fuel cell. Integrating it in our system proved difficult but with the support of Horizon we were able to fix the integration and we are now sailing on hydrogen again. In the coming month the Embedded Systems department will put all their time into making the system perfect for the race in Monaco, to make sure that it is as robust,efficient and safe as possible. Besides that, they will put a lot of time in the height control. Getting the boat to foil stable above the water will be a difficult process in which we have to test and tune a lot.

Vehicle Dynamics

IMG_2855

In May we started testing on a more extensive basis. For Vehicle Dynamics this means making sure that all the systems are running at their desired operation point. We received our newly designed propeller by Marin and built by Promarin with which the Vehicle Dynamics department could test the driveline. The driveline got tested several times with the help of a so-called bollard pull test. This is a test in which the boat is moored to shore with its motor put in forward at (almost) max speed.  This way we could test the fuel cell and the motor + driveline in one test. We managed to  get some valuable information out of it and got to see it working fully. Furthermore, the cooling system is now being fine-tuned so that it will perform optimally. Next to that, one of the most critical systems has been integrated into the boat: the foil actuation system. It has been mechanically and electrically tested outside the boat, and now it has all been put together in our boat. The only thing that is left for the Vehicle Dynamics department is tuning the PID controller, which will be done shortly! The PID controller makes sure the foils actuate based on the data the boat receives via sensors.

Our calendar for the coming month will be entirely filled with testing our boat and getting it to foil! This means that all parts of the Vehicle Dynamics department will be used a lot. Therefore wear and tear could occur. So, they will be doing maintenance tasks and checks after every test!

Boat reveal

On Monday the 8th of May we proudly presented our flying hydrogen-powered boat to the world after months of hard work. Since presenting our design in December, we started realising it and in just four months our design came to life. The traditional boat christening was performed by John Williams to wish the boat a safe journey in Monaco. John Williams is committed to getting people to work together towards a sustainable future, just like we do. At the moment John Williams is an energy coach and works with Dutch football clubs to make them more sustainable. 

Now that our boat is built we are fully focused on testing and preparing for the Monaco Energy Boat Challenge that will take place from 3 to 8 July. We will compete in the Open Sea Class, where we want to become world champions by excelling in three parts of the challenge; endurance, speed and manoeuvrability. In Monaco we will compete in the world championship to urge the maritime industry to take action and move towards a sustainable future, because together we can turn the tide.

April - Testing

The past few weeks, the whole team was busy assembling our boat; Aurora.

Hull and Body

During the assembly phase, the Hull and Body department helped the other departments assemble parts into the boat. Slowly, our Aurora was filled with parts; a weird sight to get used to and satisfactory at the same time. After Hull and Body laminated the deck onto the boat, they could also add all the parts to the exterior of the boat.
Besides the hull, the Hull & Body Department worked a lot on connecting all the hydrogen systems. Between the high-pressure system of the tank and the low-pressure system of the fuel cell, they had to bend and connect several tubes. They checked all connections by pressure testing with nitrogen. After a successful test, we were able to fill the system with hydrogen for the first time and test the fuel cell.

The Hull and Body department also dealt with the logistics for the test phase. Because we are testing with the team at an external location, we have to move our entire workshop; quite a logistically challenging operation. Furthermore, during the test phase, the roles within the team change. We will be working in a different composition than we were used to earlier this year.

Embedded Systems

During the past few weeks, the Embedded Systems department worked really hard on getting the complete electrical system to work in the boat. Having working PCB's and sensors is nice, but connecting them together brings new problems. They tested the complete electrical system contained within watertight boxes outside the boat on a table, but after mounting it in the boat they still had to troubleshoot. At first the cooling pumps were not working reliably, but the Embedded Systems department was able to identify the problem and  design a new PCB for it. Now they are working great. They wrote a lot of code for the start-up sequence of the boat, and to make the boat safe. They also had trouble with getting the motor spinning reliably, but after redesigning the cable structure and configuring the motor controller, they got it working.

The Embedded Systems department will be very busy during testing. They will write, implement and test new code functions. Besides that they will gather and analyse data to optimise the boat. Besides that, two of the Embedded System engineers will pilot the boat during testing,  and the Embedded Systems department will be closely involved as co-pilots and strategists. When testing the foil actuation, Darwin will be busy with getting the system working correctly. Meanwhile in the Dream Hall, spare PCB's will be soldered by other people so that they are ready if they need to be swapped in.

Vehicle Dynamics

unnamed

Last month everything was prepared for testing. This means that all the systems had to be installed in the boat. For the Vehicle Dynamics department, it started with installing the cooling system. This system consists of 4 closed loops and 2 open loops. The open loop systems pump (sea)water through heat exchangers. Every closed loop flows through a heat exchanger to transfer its heat to the (sea)water. Next to the cooling system, the steering system was installed as well. This system is designed to be as lightweight as possible and therefore we are using Dyneema cables, supplied by FibrXL. Furthermore the Vehicle Dynamics department assembled the driveline in the rear strut. This is a precise job, because everything has to fit securely but with tight tolerances. Luckily this went well and they were able to dry test it in the Dreamhall. They also completed the height control system. The spindles, which were lathed by Jense Machine Service, were the last parts before it could be tested. With the help of Servo motors, supplied by Maxon, this system will actuate the foils and therefore enable us to get the boat out of the water!

Testing on the water

Last week we went to our test location for the first time! We test in the harbour in Drimmelen. The harbour gives the perfect opportunity to get the boat in the water for test and get the boat out of the water to make the necessary improvements.
We will test in Drimmelen until we depart to Monaco for the Energy Boat Challenge in July. The first week we did the last few (successful) dry tests before going on the water! We tested if our boat floated and of course Aurora did. After that, we sailed on the water with power supplied by the  buffer.
Before we can test the hydrogen system on the water we need to do some more dry tests. We need to test the whole electrical system and the whole hydrogen system. For the hydrogen system we need to test the high and low pressure system to make sure there are no leaks, and we'll test the hydrogen sensors to make sure that if there is a leak we will know immediately. Lastly, we need to test the fuel cell to make sure it works as it should. When all these tests are successful we can start testing the whole hydrogen system with the boat on the water.

While we are busy with testing, the team is also busy with dotting the i's and crossing the t's for the Boat Reveal. The Boat Reveal will take place on the 8th of May in the Onderzeebootloods in Rotterdam. Here we will reveal and christen our boat! Do you want to join us on the 8th of May?

March - Assembly

The past few weeks, the Vehicle Dynamics department worked in Vollenhove at Rondal to produce our hydrofoils. The hull arrived at the Dreamhall, which was amazing for the whole team and especially for the Hull and Body department. Now that the hull is in Delft, the team has been busy with assembling the boat. 

Hull and Body

The Hull and Body department worked on the hull for the past few months and on Wednesday, the 22nd of February, the moment was there to unload the boat from the mould. Because they worked towards this moment for the past two months, there was a healthy tension in the department. For the unloading itself, the Hull and Body department had to take ample of time because our boat has a difficult shape. In the end, the department unloaded the boat by running water between the mould and the hull. When the boat floated in the mould, they carefully lifted the hull out of the mould. The boat came out of the mould like a mirror; you can see each individual carbon fibre. It is great to see the result after two months of hard work, a big milestone for Hull and Body!

After the boat was unloaded, the team welcomed the boat to the Dreamhall. Now that the hull is in Delft the team could start placing parts in the boat. Hull and Body worked mostly on assembly and slowly the boat filled up more and more. Once all the major components were put in the boat, the Hull and Body department went back to Contest Yachts to attach the deck to the boat. After two days of hard work, the hull is now finished. Now that the deck is on the boat, the Hull and Body department will connect the hardware of the hydrogen system and they'll put other small components in the boat.

Embedded Systems

In the last few weeks, the Embedded Systems department worked a lot on their design, production and assembly. They have designed and soldered all our PCB’s (Printed Circuit Boards), wrote a lot of code to program the chips on the PCB’s, produced battery modules for the buffer battery and performed big tests where they integrated all our systems together. The Embedded Systems department has made some big achievements: The newly produced buffer battery is working, the Brightloop step-down converter is converting the high voltage to lower voltage, the Maxon actuator motors for the foils are reacting to inputs from our sensors and most importantly; the electro motor, which will be used for the propulsion, is spinning when given inputs from the steer.

The Embedded Systems department works in an iterative process, when they discover things that need to change during assembly, they go back to their laptop to rewrite the code and to design and produce new PCB's. At the moment, the Embedded Systems department is working hard at Van der Leun to put all components in watertight boxes from Phoenix Mecano. Afterwards, they will connect all systems together with cables from Phoenix Contact. In the coming weeks, all the systems will be dry tested before testing the boat in water.

Vehicle Dynamics

For the Vehicle Dynamics department, the month March is all about producing hydrofoils. The foils are made of carbon fibre and a stainless steel made insert. The carbon fibre is laminated layer by layer into MDF moulds. When all the layers are on, the mould + carbon is put into a big oven which hardens the resin and thus cures the foil.

Next to building the foils, a lot of work on other subsystems was done by the Vehicle Dynamics department. The rear strut is finished as well as all the parts for the foil actuation system. To help ease the production of those parts, Dormer Pramet provided milling and lathing tools.

Furthermore, the cooling system has been assembled completely outside of the boat to see if nothing was missing. After that, the cooling parts, like the pump from Xylem and the heat exchanger from Bowman, were assembled in the boat. For the Vehicle Dynamics department, only a lot of smaller parts are left for production and assembly now. They will proceed with these smaller parts after they finish the hydrofoils which will be at the end of March.

Dry Testing

Now that the boat is almost fully assembled, it is time to dry test the boat. In the coming weeks we will dry test all the different systems in the boat to make sure they work as expected. Some systems have already been tested outside the boat but we also need to test the integration of all the systems. After all the dry testing we can prepare the boat and the testing location for the wet testing; testing with the boat in the water. The team is really excited that we will dry test the different systems in our boat in the coming weeks and we are all looking forward to the wet testing in one month from now.

Another exciting moment is coming up; wrapping the hull. The bottom side of the hull is already wrapped but for the top of the hull we needed to laminate the deck first. Now that the deck is laminated the wrap will be put on the hull by Omber Reclame. Curious about the design of the wrap? The wrap will be revealed at our Boat Reveal in May!

Taking the next step

First of all I would like to wish you a Happy New Year on behalf of the TU Delft Hydro Motion Team. Before the holidays, we had an amazing Design Presentation where we could finally share our design with all of you. Let’s look back briefly on this wonderful night!

Over the last 17 years we have built amazing boats that sail on sustainable energy sources, inspiring the maritime industry to move to a more sustainable future. But now it is time to take action; with our design, it is time to turn the tide.

This year we want to win the Monaco Open Sea Class in July 2023 with our foiling hydrogen-powered boat. With this in mind, we researched the possibilities to reach our goal and we started designing our boat. After making hard choices and working long days we finished our detailed design phase.

The hydrofoils are an important part of our boat because they enable the boat to “fly” above the water, which is called foiling. When the boat is foiling the drag becomes significantly less and therefore we can sail faster with less fuel. With this mechanism we can win the World Championship in Monaco. 

Foiling is important to win the Monaco Open Sea Class 2023, because it allows us to reach a similar speed as our competitors who sail on batteries. In order to foil, the boat needs to reach 25 km/h. At this speed, the hydrofoils create enough lift to raise the 1400 kg boat out of the water. Because the competition takes place on the open sea, the boat has to withstand waves that can make the boat unstable. At the same time, the boat also needs to be lightweight to foil. In order to get this done we made some improvements compared to last year. 

Hull and Body

The Hull & Body Department has focused on a lighter and more efficient hull shape. The boat has become more efficient by adding the chine, the horizontal ledge, where the bottom transitions to the side. In addition, the bow has been rounded and the boat is optimised for our hydrogen system. This year we’ll have a dead man’s switch, which means we’ll only need two pilots compared to three pilots last year. Because of this, the position of the fuel cell has moved forward and the tanks are placed more to the middle instead of the side of the boat. This allows the boat to be more compact and thus lighter. Ultimately, the weight of the boat affects its foiling characteristics.

Embedded Systems

This year the focus of the Embedded Systems department is to make the electrical system robust and reliable, while keeping it as simple as possible. The department will reuse many components of last year’s boat, such as the fuel cell and the motor controller. However, they will also produce and use many new and innovative components. The department will receive a new, stronger and more efficient motor from Emrax. Besides this, they will make use of a new step-down converter from Brightloop to create the lower voltages needed for all auxiliary systems. The auxiliary systems consist of all systems required in addition to the power system, such as the bilge pumps and display. 

We are also designing and producing a new buffer this year, which will have a lower mass and will be safer to use. Lastly, the system architecture and height control system will have a completely new design. The cable tree is redesigned, new Printed Circuit Boards are designed, and the height control system will be designed in such a way that it will be more reliable and responsive.

Vehicle Dynamics

The Vehicle Dynamics department has been really busy designing parts in CATIA for the last 2 months. CATIA is a 3D digital modelling program developed by Dassault Systems. They not only designed the cooling, steering and foil actuation system, but also the driveline, struts and foils. It was a very busy period in which they used a lot of knowledge of our partners and alumni. The Vehicle Dynamics department has been working hard on optimising the height control system. This is the system that will enable us to foil in a stable manner. It consists of the actuation system, sensors and control system. The latter is the custom programmed PID controller, which is a way of optimising the flight characteristics.

Operations department

The Operations department was busy with organising the Design Presentation before the holidays. Not only the content of the presentation needed to be written, but also the music, light, and countdown had to be prepared for the presentation. The department worked hard on organising the drinks and questions afterwards. Besides organising the presentation, Operations actively worked on our social media and press releases, and External Relations worked on staying in touch with our partners.

Production

Now that the design phase is finished, we have started the production phase. Everything we designed will be produced, which is really exciting! From now on we will slowly see our design come to life.

Hull and Body

The Hull and Body department has already started production of the hull at Contest Yachts in Medemblik. During production, the department puts a lot of focus on their personal health and safety. They are wearing proper personal protective equipment which is needed when working with carbon fibre. They are building the hull in a direct mould of about 8 by 3 metres and, despite this size, they were able to set the mould down with a precision of 1 mm. This shows that the department works meticulously to minimise the weight of the boat. The Hull and Body department is now 3.5 weeks into production and they plan to build the hull within 7 weeks.

Embedded Systems

During the coming weeks the Embedded Systems department will be designing, producing and testing all components of the electrical system. There are a lot of different systems, which all have to be controlled by software. The department will design and solder PCB’s, which are debugged and tested thoroughly. After that they will put most of the components in watertight boxes from Phoenix Mecano so that the electronics can be put safely in the boat. We will then connect everything together with cables from Phoenix Contact and Van der Leun so that the data and power can be transferred between the systems. After that everything will be dry tested thoroughly, so that we are sure that everything is working correctly when we test the boat in the water. 

Vehicle Dynamics

The coming weeks the Vehicle Dynamics department will produce a lot of parts. Those include parts for the steering and foil actuation, but most importantly: the custom designed foils. The department is going to produce these at Rondal in February. Next to that, the struts are being produced in the Dreamhall with the help of Salim, the CNC programmer of the Dreamhall. Furthermore, the sleeves, which connect the struts with the hull, are also produced in-house. In week 6 we will install those in the boat, which will then still be at Contest in Medemblik, together with the tube assembly (connection between the rear strut and hull).

Operations department

The coming weeks, Operations will be busy with designing the wrap of the boat. Designing the wrap will be done in collaboration with the team through brainstorming sessions and by giving the team the opportunity to voice their opinion about the different concepts of the wrap. 

Even though we’ve just had our Design Presentation, Operations is already working on the next event. The Christening of the boat will take place in spring and the department will work on preparing this event in the coming weeks as well.

Newsletter

For the coming weeks we will be working hard on the production of the different parts we need for the boat. The next newsletter will be out in a month!

A new year, a new team, a new boat

Each year there is a whole new team that is eagerly waiting to take over the project of last year’s team. Before I’m going to introduce us I will first look back on the previous team and their performance in Monaco.

Last July, the team of 2022 traveled all the way to Monaco, facing an extreme challenge. They managed to become second in the Monaco Open Sea Class 2022. A huge achievement. There was strong competition in the maneuverability race, nevertheless the team managed to secure an excellent second place. This good start unfortunately could not be continued to the speed section, during the race, the boat suffered from technical defects, which prevented it from completing the race. Despite this being a huge disappointment, the team put in an excellent performance in the final section; the endurance race. With 17 laps, they sailed convincingly to first place after the competitors were far behind. Because the competitors still work with batteries, this also showed the power of hydrogen and its advantages for long distances.

With these results, the team then finished 2nd in the world championship. The entire team is extremely proud that they managed to design, build and race a hydrogen-powered boat in just one year.

To enjoy these moments one more time, the after movie is out now!

Meet the team

Now a new year has arrived with a new team, a new goal and a new boat. Last August, the next generation of the TU Delft Hydro Motion Team started. We spent the last three months studying last year’s boat and designing the 2023 boat with the accumulated knowledge. Our aim is to demonstrate the applicability of new technologies by taking the next step in bridging the gap between the ‘technology of the future’ and the current norm. Within one year, we are creating an innovative boat powered by green energy to demonstrate the potential of sustainable solutions in the maritime industry.

Our goal this year is to win the Monaco Open Sea Class 2023 and become world champions with a foiling hydrogen-powered boat.

To get acquainted with the new team, the team reveal video is out now, which can be viewed here:
