The Netherlands based Acta Marine, which has a newbuild walk to work construction support vessel (CSV) nearing completion at Ulstein Verft in Norway, has ordered a second CSV at the yard.
The second vessel is scheduled for delivery Q2 2019, and is of the SX195 design, the same as the first vessel, Acta Auriga, which will soon go to sea trials before embarking on a two-year charter for operations at BARD Offshore 1 wind farm Germany.
Rob Boer, managing director at Acta Marine, said the company opted to order the sister vessel because it was pleased with the first project: “Our first CSV, Acta Auriga, at Ulstein Verft will go for sea trials shortly, and we are very pleased with the progress of this project. Returning to Ulstein Verft with an order for a new sister vessel is a strong signal of the importance of the yard’s track record in quality and delivery precision, which is very important to us as ship owner and to our clients.”
“We are quite convinced that the Acta SX195 vessels will create higher efficiency in offshore logistics operations and thus reduce the overall cost of constructing windfarms and, also, contribute towards a higher uptime of the installed base of offshore wind,” Boer said.
The 93.4m long and 18m wide vessel is optimized for offshore wind. It has a large, centrally positioned SMST provided walk to work motion compensated gangway and elevator tower for personnel and cargo transfers. And further a 3D compensated SMST crane capable of 6-ton cargo lifts. The optimized onboard logistics includes large storage capacities, of which half is under roof in a controlled environment, and stepless approach to the offshore installations. The vessel is equipped with a fuel-efficient drive system. In addition, a helideck will be fitted. With all main equipment and operations in the aft ship, the vessel will naturally operate astern while in-field. Keeping the X-STERN towards the weather, there will be no slamming, noise or vibrations caused by the waves. The crew will get complete rest between shifts.
“Acta Marine is stepping up its activities in offshore wind. These ship designs are flexible and attractive for work within areas such as O&M (Operation and Maintenance) or construction support especially in challenging weather and sea conditions” says Rob Boer.
The vessels are capable of year-round, North Sea offshore operations in up to 3m significant wave heights, offering safe transfer of service crews, cargo and spare parts, the in-field flexibility and high comfort. Each vessel can accommodate up to 120 persons.
