Ulstein Design & Solutions on Friday (25 September) said it signed a contract with PaxOcean Group, a member of Kuok Maritime Group, for the design of an ULSTEIN SX222 service operation vessel (SOV) for NYK Line.
PaxOcean will construct the vessel at its Graha yard in Batam, Indonesia.
The vessel will support offshore wind construction, operations and maintenance activities, providing accommodation and logistical support for personnel working offshore.
The new SOV will be based on the proven SX222 design and will accommodate up to 120 people. The vessel will have a length of 89.6 metres and a beam of 19.2 metres.
Featuring Ulstein’s TWIN X-STERN® hull design, the vessel is designed for high manoeuvrability, efficient station-keeping and reduced energy consumption. The symmetrical hull shape and propulsion arrangement allow the vessel to operate efficiently in either direction. This reduces the need to turn when weather conditions change and supports a wider operational window.
The vessel will be prepared for methanol and fully electric operations, providing flexibility to adopt lower-emission energy solutions. It will have double classification from DNV and CR and sail under the Taiwan flag.
“This contract is an important project for PaxOcean Group as we strengthen our capabilities in specialised vessel construction. Together with NYK and Ulstein, we have worked closely and purposefully over time to develop a vessel that meets the customer’s operational requirements and the evolving needs of the offshore wind industry,” said Sidat Senanayake, Group Head of Commercial at PaxOcean.
“For PaxOcean, it is also significant that we are establishing a strong foothold in a segment of tonnage that directly contributes to and enables sustainable solutions. This is an important step in our continued development and in positioning ourselves for the green transition taking place across the maritime industry.”
