Acta Marine Takes Delivery of Walk-to-Work Vessel Acta Centaurus

Building on the experience with the first Ulstein Walk-to-Work construction support vessel the Acta Auriga, the yard has now delivered its sister vessel, the Acta Centaurus.

The vessel was handed over from Ulstein Verft to Acta Marine on 26 April. Acta Marine will deploy the vessel for the offshore industry and the renewables market in particular.

X-Bow and X-Stern Increase Comfort and Reduce Fuel Consumption

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.

Logistics Solutions

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 1000 m2 in total, indoors and outdoors, with a container skidding system and ample space for in total 24 containers. All cargo handling is centralised, with stepless transfer to the cargo and personnel lift, and likewise over to the wind turbines or offshore platform. In addition, the Acta Centaurus is fitted with a helideck to further support offshore operations. 

Safe and Stepless Transfers in 3 Metre Waves

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 has also delivered the 3D motion compensated knuckle boom crane which can handle 6 t cargo in sea conditions of up to Hs 2.5 metres.

Low Noise and Vibration Levels

Acta Centaurus features state-of-the-art "smart hotel style" accommodation for up to 120 people. 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.
