    ULSTEIN, Norway — Olympic contracts two firm construction service operation vessels (CSOVs) and two options at Ulstein Verft.

    The vessels have hybrid battery propulsion and are prepared for methanol fuel to enable zero emissions. They are based on the ULSTEIN SX222 design with TWIN X-STERN from Ulstein Design & Solutions AS.

    Norway-based Olympic has a fleet that operates in the subsea service and renewable energy markets. Olympic has previously built six vessels at Ulstein Verft and was the first customer of Ulstein Design & Solutions.

    "The TWIN X-STERN is a smart concept, optimized for low energy consumption," said Olympic Group CEO Stig Remøy. "During operation, the offshore wind service vessels stay positioned at the turbines most of the time, and with the main propellers fore and aft, these vessels will reduce the energy requirement to a new level when on DP."

    The ULSTEIN SX222 vessels have a length of 89.6 m and a beam of 19.2 m. They accommodate 126 people in 91 cabins. The vessels are prepared for future requirements at the offshore wind farms. The vessels are powered by diesel-electric propulsion with variable speed in combination with large battery energy storage systems. The vessels are prepared for methanol fuel and have available space for additional battery capacity for full-electric repowering when the infrastructure for such is available. 

    Ulstein said these contracts are an important milestone also for Ulstein Power & Control AS, as they are contracted to deliver an extended power and automation package, including a large battery supply.
