After five years of market consultation, research, design, engineering and construction, the first of Damen’s ground-breaking Fast Crew Supplier (FCS) 7011 class has completed its sea trials off the Turkish coast and is set to begin the passage to the Netherlands.
According to the maritime solutions provider, Damen, the offshore energy market and prospective customers will soon experience the comfort and capabilities of the 74-metre, 40 knots, 122-passenger crew change vessel.
The FCS 7011, in combination with the latest Ampelmann walk-to-work system, represents the very latest in marine access thinking, having been developed in consultation with the offshore energy industry and leading maritime research institutes. Its goal is to meet the challenges presented by the unpredictability of oil prices and increasingly competitive renewable energy. As a cost-effective crew transportation solution featuring the highest levels of comfort and safety, it offers a viable alternative to helicopter transport. It has already gained substantial interest from clients in the southern North Sea, the Gulf of Mexico, Brazil and West Africa.
The business case is based on its ability to transfer much larger numbers of personnel for longer distances at higher speeds. This opens the door to moving away from day-rate structures towards a pay per journey model and, potentially, vessel sharing, whereby multiple offshore installations can be served in a single round trip, thereby delivering substantial savings in both time and operational costs.
With journey times of up to 12 hours, comfort and safety are critical. To achieve this, the design incorporates the Damen Sea Axe bow, the positioning of the accommodation just aft of amidships, and interceptors fitted within the vessel’s stern, all to minimise sensations of motion as it moves through the sea. The FCS 7011 also features a range of motion-compensating technologies to optimise the safety of crew transfers. These include a Kongsberg DP system, a tailor-made Ampelmann gangway and a VEEM gyrostabiliser, operating alongside the MTU main engines, Hamilton waterjets, Danfoss shaft generators, Reintjes gearboxes and Veth bow thrusters. The result is a tightly integrated advanced control system capable of delivering and receiving personnel safely in a wide range of sea states, the company said.
On arrival in the Netherlands, the Ampelmann gangway system will be installed, making the FCS 7011 ready for fully integrated, proof of concept trials in the North Sea. By joining forces to commercialise the vessel, Damen and Ampelmann have combined their experience in designing and building crew change vessels with the industry-leading walk-to-work expertise of Ampelmann, the company added.
