The shiny white, 10-meter-long foundation sides that connect the wing sail with the ship deck, or the concrete base in Landskrona, laid steadily on the trailer when arriving at the yard this February. It was gently placed on the big welding area inside the assembly hall.
“I’m excited today. For the past two years it has been PowerPoints, drawings and discussions with the suppliers. Now we will see the real components and can start the assembly. It’s getting real,” says Senior Product Manager Jonas Alvan.
Future crew training
The landbased prototype in Landskrona will serve several purposes:
- Test and optimise assembly, to ensure an efficient operation when the RoRo vessel Tirranna will get her wing sail onboard
- Optimise the automation system and trimming
- Test the safety philosophy
- Training facility for future crew
The assembly started in late February, and the prototype will move outdoors to the concrete base around summer.
“This is the moment of truth. We will see if the components fit together as we hope that they will do, and if our instructions and processes that we developed for the assembly, will work, says Landskrona site manager Björn Ohlsson and continues: “It will be some challenges, but having the opportunity to build a full-scale prototype will give us great opportunities for our continuous improvement work for coming generations of the wing sails.”
“Designing a wing sail from the start is extensive work, and a small change on one component can lead to a lot of changes on another component. It’s like an organism where you need to see the whole picture all the time. And as we are designing in a quite high pace, we are also manufacturing components at the same time” says Jonas Alván.
A twin for onboard installation
During fall, the wing prototype will be up and running. A few months later, after necessary testing, a twin to the wing sail will be installed on Wallenius Wilhelmsen´s vessel Tirranna, making our first demonstrator vessel a reality. Results from the Tirranna retrofit will lay the basis of how we proceed with the multi-wing demonstrator, Orcelle Wind.
