The service operation vessels for offshore wind farms get newly developed Safe Transfer Boats
The SOVs are to be equipped with the STB 7 and STB 12; ESVAGT’s entirely newly developed Safe Transfer Boats designed specifically for offshore wind farms.
The boats benefit from ESVAGT’s 20 years of experience designing and developing the most optimal boats, and both new designs have proven themselves to be exceptionally capable during tests. Fundamentally, focus has been on optimising the boats to ensure safe transfer for wind turbine technicians more than for saving human lives in extreme weather.
The STB 7 is particularly stable, manoeuvrable and powerful in reverse. Powerful, in built, thrusters have proven to be invaluable in heavy sea current. Wind turbines at sea only have one landing and the powerful thrusters make it possible to go right onto the landing – no matter how heavy the current.
The STB 12, the first covered boat in ESVAGT’s own design, is extremely manoeuvrable thanks to its two extra bow thrusters. The boat is very comfortable and noise level is low in the cabin. With manoeuvring room both fore and aft, it has been optimised for the transportation of spare parts and goods. The boat has been put through comprehensive safety testing, as is standard for ESVAGT. The boat itself has been load tested to 32 tons and the hook system to 152 tons. The boat is an independent unit that can, for example, sail to land to collect spare parts.
Both the STB 7 and the STB 12 have inbuilt redundancy in all areas that provide back up systems in case of failure.
The STBs have been designed as a supplement to the Walk to Work gangway system.
ESVAGT is a dedicated provider of safety and support at sea, founded on an experienced and well-trained offshore crew and unmatched rescue capabilities.
We support the offshore Oil & Gas industries with a wide range of specialized services: Standby, Emergency Response and Resque Vessels (ERRV), Oil spill response, Firefighting, Tanker assists, Rig moves, Supply services and Interfield transfer of cargo and personnel.
In 2010, ESVAGT brought the dedicated offshore wind Service Operation Vessels (SOV) to the market. The SOVs provide accommodation for up to 40 technicians, storage for small turbine parts and a workshop, plus personnel and equipment transfer capabilities by either Walk-to-Work gangway system or Safe Transfer Boats.
ESVAGT was founded in 1981 and has a fleet of more than 40 vessels and more than 900 employees on- and offshore.
