The delivery of Acta Aquarius completes Acta Marine’s four-vessel DP2 CSOV programme, featuring dual-fuel methanol capability and battery power
Acta Marine has taken delivery of Acta Aquarius, the fourth and final vessel in its next-generation fleet of Walk-to-Work (W2W) DP2 Construction Service Operation Vessels (CSOVs), completing a four-vessel newbuild programme constructed by Tersan Shipyard in Yalova, Turkey.
The delivery marks the completion of a significant fleet expansion programme, following the earlier deliveries of Acta Pegasus, Acta Hercules and Acta Gemini. The new vessels strengthen Acta Marine’s capacity to support the growing offshore wind sector with modern, efficient and increasingly sustainable offshore solutions.
As the final vessel in the series, Acta Aquarius marks an important milestone in Acta Marine’s ambition to support the offshore energy sector with increasingly sustainable vessel solutions. Acta Aquarius is certified and operates as dual-fuel methanol powered vessel. Combined with her battery power system, this supports Acta Marine’s pathway towards lower-emission offshore operations, while maintaining the safety, reliability and efficiency at the core of its Walk-to-Work services. Acta Aquarius is accompanied by daughter craft Acta Situla, which was delivered to Acta Marine earlier this year in June.
Rob Boer, CEO of Acta Marine, commented: “The delivery of Acta Aquarius is a proud moment for Acta Marine and marks the completion of our four-vessel newbuild programme with Tersan Shipyard. Together, these vessels represent an important investment in the future of our fleet and strengthen our ability to support our clients in the offshore wind industry. With dual-fuel methanol propulsion capability, Acta Aquarius marks an important step towards more sustainable offshore operations, significantly reducing CO2 emissions, while continuing to provide the safe, reliable and efficient services our clients expect from us.”
With its four-vessel Construction Service Operation Vessel (CSOV) newbuild programme now complete, Acta Marine will deploy Acta Aquarius to further strengthen its offshore wind support capabilities, providing safe, reliable and increasingly sustainable offshore solutions.
