Incident with battery TU Delft Solar Boat Team

Last night there was smoke in our workshop. The fire department came to check and make sure the situation was safe. The source of the smoke was an old battery from 2012 which spontaneously combusted. This caused a fire in the fire containment container. This is a container in which our batteries are safely stored. The fire containment container has fortunately done its work and kept the fire in the container, allowing only smoke to escape this container.

The battery from 2012 is regularly used during events with old boats and has never had problems before. However, we know that this type of battery is highly flammable and that something as small as a misplaced connection can already be enough to cause a fire. Since this is known to us, we have taken security measures by storing the batteries in the fire containment container. We are now busy taking steps to ensure that this type of incident will not happen again.

The Fire Department has come to our workshop as soon as possible and has removed this fire containment container from the workshop in order to be able to extinguish it safely and to further investigate.

Our team, of course, was shocked by the incident. We all came to the D:Dreamhall as soon as possible to make a plan of what needs to be done. We are very fortunate that there is no damage to our boat and that nobody was harmed. That is the most important thing for us right now.

The energy box of the 2018 Solar Boat was also seriously damaged in the incident because it was in this same container. It is important for the team to switch its focus on producing a new energy box so we can use it during our race this Friday in Purmerend. In addition, the team is still in the process of repairing last week’s damage to the boat. It is a busy and demanding period during which it comes down to pure teamwork.

“Teamwork is the only solution to this situation” – Damage to the TU Delft Solar Boat 2018

Last Monday, our boat was damaged during a test where we tested top speed. While we were flying at a speed of 50 kmph, there suddenly was a force which was too big for our rear-steering system. Therefore, our rear strut turned 90 degrees. This caused so much force on the strut that this torn apart our hull and we lost our hydrofoil at a depth of 40 meters. Because of the hole in the hull, water entered the boat which damaged the energy box and electromotor. Our team was immediately focused on making sure the boat is repaired as fast as possible to make sure we can participate in the next Solar Sport One race in just 8 days. To reach this, our team works in shifts, day and night, to repair the hull at our partner Rondal / Royal Huisman to repair and redesign the rest of the systems in our workplace in Delft.
With teamwork, we will get out of this situation even better. Our steering system is new and with a boat like this, situations like this will occur. By working hard as a team, we can prevent that something like this will happen again! #Teamwork #GoSBT

The first race of the TU Delft Solar Boat Team

Last weekend, May 11 – 12, our team, the TU Delft Solar Boat Team, had the first race of the Solar
Sport One 2018 competition. The first race was held in Akkrum, Friesland, and was the first of five
races in the competition. The goal of our team is to win the overall ranking of the Solar Sport One
competition.

On Thursday, May 10, our team packed the last things and we went to Akkrum by car. When we
arrived in Akkrum, we built up our campsite, prepared the strategy headquarters, did the last tests
for the boat and prepared the Support, Scout and PR cars for the race. The next day, May 11, the
Time Trial race took place. This race consisted of a 55 km route which had to be finished as fast as
possible. Our team started as the last boat of our class. Despite this late start, we overtook the
biggest part of our competitors very soon in the race, bringing us to a second position with only Clafis
Victron Energy ahead of us.

The TU Delft Solar Boat Team became #2 of the first race – Paul Schellekens
During the race, teamwork was essential. Our Support Crew had to be ahead of the boat at all times
in order to prepare themselves for pit-stops and check-ups. Our Scout Crews positioned themselves
ahead of the boat all the time in order to collect all the weather- and environmental data to provide
our Strategy Crew with the desired information. The Strategy Crew then used this data in
combination with the data of our boat to decide the optimal way of sailing to fit our strategy. Our
communicator Tim had to filter all the information into an easy and calm message for the pilot.
This teamwork resulted in our boat finishing second, behind Clafis Victron Energy. This result was
very exciting since we managed to perform so well, even though our team has had so little time
before the races with the new boat.
“The team ahead of us has not built a new boat for more than 4 years already, making their boat
optimal and their pilot more experienced. I am very proud that we came this close while our boat
and team is entirely new!” Team Manager Sjoerd Says.
The following day, the Endurance race called Rondje Akkrum and the Sprint were on the planning.
During Rondje Akkrum, we had to sail as many laps around Akkrum in just one hour. Again, we
managed to end up second, behind Clafis Victron Energy. This time, it was a very close call with
University of Twente Solar Boat Team, since they ended up with 1 less lap than we did!

Lastly, the same day, the Sprint Race took place in Akkrum where we had to sail for 360 meters as
fast as possible. We finished in 52 seconds, as fourth, 2 seconds behind Dutch Solar Boat Team and 2
seconds behind University of Twente Solar Boat Team.
Our team is very proud of the result of this weekend’s race, since we became second in the overall
race. This result gave us even more motivation to work even harder to improve ourselves and the
boat for the next races.

Dorian van Rijsselberghe launches the TU Delft Solar Boat 2018

Yesterday, two-times Olympic Champion Dorian van Rijsselberghe christened the TU Delft Solar Boat 2018! Dorian and our team addressed the need for a cleaner way of living. During the launch, Dorian, as ambassador of the Plastic Soup Foundation, showed the amount of plastic that we fished out of the water before the event to show that there needs to be a change in the way we use plastic.

We are very grateful that we had the opportunity to inspire people thanks to all the press.

Boat launch by Dorian van Rijsselberghe

On the 1st of May, we will christen the TU Delft Solar Boat 2018 at the Oostpoort in Delft. We are honoured that two-time Olympic Champion Dorian van Rijsselberghe will christen the boat. In addition to showing what is possible with renewable energy, our team thinks living a cleaner lifestyle is very important.
Since 2013, Dorian has been an ambassador of the Plastic Soup Foundation. As a windsurfer, Dorian wants the sea to remain as clean as possible and for this reason he became an ambassador of the PSF. This foundation is fighting the plastic pollution of our water. Dorian: “We throw garbage on the street and in the water carelessly too often and that has to stop”.

Meet Alexander

Meet Alexander,

Alexander was born in Malle, Belgium. From his second to his fifth year he lived in Shibuya, Tokyo (Japan). Here, he went to the International School where after he moved back to Belgium to graduate from the European School in Mol.

Four years ago, Alexander moved to Delft to study Civil Engineering. He chose Civil Engineering because of his passion for trains and railways. After getting his Bachelor’s degree cum laude, Alexander started his Master’s in Structural Engineering. Here, he focuses on designing slender structures, connections and knowledge of materials.

Alexander joined the TU Delft Solar Boat Team because he wanted to do something else than studying for a year but still wanted to spend this time useful. After seeing the TU Delft Solar Boat Team testing at D.S.R. Proteus-Eretes, Alexander directly knew he wanted to join the TU Delft Solar Boat Team. He could only dream of the efficiency of the boat.

This year, Alexander wants to help the team win the Solar Sport One competition as our Structural Engineer by making a winning hull. This year, he is responsible for the strength and stiffness of the boat. This year for the first time this happens in the philosophy of probabilistic design and conform the Eurocode. The boat is very fragile because it only contains a single layer of carbon for the inner skin and a single layer for the outer skin. Reinforcements were used only where necessary and recesses made where possible. Also with his skill achieved at the Matcie of Proteus, he opts for a high quality of production. This resulted so far in a hull and deck that is larger and just as light as in previous years.

In addition to his time at the TU Delft Solar Boat Team, Alexander plays occasionally the organ. He learned this in his youth at the music school. In addition, he has developed a great passion for rowing.
