The wing sail foundation is now installed on Tirranna´s deck, and the vessel is one step closer to getting its wing sail. The installation was performed during Tirranna´s planned docking at IMC Shipyard in Zhoushan, China.
Oceanbird is currently producing two full-scale (40*14 meters) prototypes: one land-based in Landskrona and one to onboard Wallenius Wilhelmsen´s vessel Tirranna. The wing sail foundation, which connects the deck to the wing sail, has now been welded on deck during Tirranna‘s ordinary 5-year docking process.
“The installation went as planned. Overall, it was a successful operation. Since this is our first installation, we had a lot of valuable learnings” says Oceanbird´s Customer Project Manager Emil Kotz, who has just returned from the shipyard in China together with Oceanbird´s engineers Georg Svedling and Erik Lincoln.
Wing sail installed in Europe
Besides welding the foundation on deck, the modifications on Tirranna also included steelwork to strengthen the vessel and cabling work to ensure the interface between vessel and wing sail. The vessel will be equipped with a wing sail in Europe during the first quarter of 2025.
“We did as much preparations as possible to avoid unnecessary off-hire during the wing installation in port. Together with the crew from Wallenius Wilhelmsen and the shipyard, we managed to get everything done during the planned docking time”, says Emil Kotz.
