“Building on experience with our first Ulstein Walk-to-Work construction support vessel Acta Auriga delivered to us last year, we are highly confident that Acta Centaurus will be very well suited to operate in the offshore, and specifically the renewable market. We will now get ready to bring her out to the Offshore Wind Farm to commence work,” says Rob Boer, managing director in Acta Marine.

The importance of on-time deliveries

“We know how important it is to get a vessel completed on time. This has been achieved through good cooperation between Acta Marine and Ulstein on all levels” says Kristian Sætre, managing director at Ulstein Verft, and continues: “We feel certain that the Acta Centaurus will be a good work platform for the owner and their clients.”

Logistics

The optimised on-board logistics solutions of this vessel have been developed by considering the flow of people in various work operations. The vessel offers large cargo areas of totally 1,000 square metres, indoors and outdoors, with a container skidding system and ample space for in total 24 containers. All cargo handling is centralized, with stepless transfer to the cargo and personnel lift, and likewise over to the wind turbines or offshore platform. In addition, Acta Centaurus is fitted with a helideck to further support offshore operations. The overall logistics and the SMST motion compensated gangway, and integrated elevator tower will secure safe and stepless transfers of people and cargo in significant wave height up to 3 metres. SMST also delivered the 3D motion compensated knuckle boom crane which can handle 6t cargo in sea conditions up to Hs 2.5 metres.

Hotel style

Acta Centaurus features state of the art ‘’smart hotel style’’ accommodation for up to 120 persons. Ample office and works spaces are available for charterers. The mess room and lounge area include a library, coffee corner and a game room. The vessel also has a sauna and a gym/exercise room and offers very low noise and vibration levels which are rated better than the requirements for DNV-GL comfort level V2 class.

Ship design

The vessel is equipped with the hull designs X-BOW® and X-STERN®. The X-BOW® is important when the vessel is transiting in heavy seas, reducing slamming and vibrations with a positive impact on the well-being on board. The X-STERN® has much of the same qualities as the X-BOW® and will secure a higher in-field flexibility and improved winter workability. When keeping the stern facing the weather on dynamic position (DP) the vessel will be able to stay positioned with lower thruster load, resulting in a lower fuel consumption.
