Acta Centaurus, the second SX195 construction support vessel ordered by Acta Marine from Ulstein, has commenced the final phase of construction at the shipbuilder’s Norwegian yard in Ulsteinvik.
The vessel’s hull arrived at Ulstein Verft on 10 December, where it will undergo further outfitting and testing, from Ulstein’s Gdynia yard in Poland where the initial phases of construction took place.
Scheduled for delivery by the beginning of Q2 2019, Acta Centaurus is the third walk-to-work vessel in Acta Marine’s dedicated offshore logistics and accommodation fleet, which services both the offshore oil and gas and renewable energy sectors.
Sister vessel to Acta Auriga, Acta Centaurus offers walk-to-work transfer of crew and cargo via a motion-compensated gangway able to operate up to 3 m significant wave height. It is also equipped with a 3D motion-compensated knuckle-boom crane able to handle loads of up to 6 tonnes in sea conditions of 2.5 m significant wave height. Up to 120 people can be accommodated and there is 1,000 m2 of deck space for cargo storage.
The vessel shares its sister’s innovative use of Ulstein’s X-BOW and X-STERN hull concepts, which utilise a wavepiercing tumblehome hullform to offer greater stability whether under way or in dynamic positioning (DP) mode in rough seas. While under way, the X-BOW is able to absorb impacts more consistently across the hull’s surface, resulting in greater stability and reducing fuel usage. When operating in DP mode, the X-Stern can be faced into the wind to boost performance by offering reduced pitch motion, wave response and slamming, reduced trim and draft sensitivity and increasing the operational window.
