Ulstein to build two offshore wind vesselsVessel & ROV News // January 14, 2015
The SX175s are the first offshore wind vessels to be built at Ulstein Verft.
Ulstein Verft has signed a contract with Bernhard Schulte in Germany to build two service operation vessels (SOVs) of Ulstein SX175 design, a design developed by Ulstein Design & Solutions.
The final detailed arrangements and equipment for the vessels were developed and specified in cooperation with Windea Offshore GmbH & Co KG, which is the Bernhard Schulte’s affiliate for offshore wind projects.
“Delivery schedule reliability was our number one priority when choosing the shipyard. We considered several yards worldwide, but Ulstein Verft was our final choice. They have a solid reputation, not only on keeping to delivery schedules, but also of delivering innovative vessels of high quality,” said Matthias Müller, Business Development Director at Bernhard Schulte.
“These are the first service operation vessels for the wind industry to be built at the yard and we look forward to delivering the two vessels in the second quarter of 2016 and first quarter of 2017,” said Kristian Sætre, Managing Director at Ulstein Verft.
The vessels can accommodate 60 people in single cabins, of which 40 cabins are dedicated to technicians who service wind turbines.
An offshore wind service vessel’s most important task is to stay positioned on DP close to the turbines, with as little movements as possible, in order to provide a safe transfer for the technicians from the vessel through a heave compensated gangway to the turbines.
The vessels will be the first of the ULSTEIN SX175 design, which was specifically developed to meet the requirements for the offshore wind industry. Important features include the new X-STERN hull line design as well as the proven X-BOW. The vessel can operate with stern or front to the wind, waves and current, increasing the operational window.
