Marine operations company Green Marine Energy Support Services, based in Stromness, Orkney (Orkney Islands), recently took delivery of a Damen MultiCat 2712 workboat for itsoffshore wave and tidal activities. The vessel’s first job was laying the moorings for and towing Green Marine’s heavy-lifting barge and the removal of the HS1000 tidal turbine for Andritz Hydro Hammerfest, which was carried out successfully and in record time.
With a length of 27.7 metres and a beam of 12.45 metres, the Multi Cat 2712 workboat, which was christened Green Isle, is a standard design with several modifications, i.e. a customised mooring system and Green Marine’s own winches, which were installed by Damenand commissioned on board. The vesselhas a speed of 10 knots, complies with the MCA CAT 1 workboat code and has a maximum bollard pull of 34.8 tonnes (average 33 tonnes). The workboat’s basic functions for Green Marine will be anchor handling, installing wave and tidal energy devices, assisting barge operations, dredger service, supply, towing, hose handling and survey. For propulsion it is fitted with two Caterpillar C32 TTA ACERT engines with a total power of 1, 790 bkW at 1, 800 rpm.
Typical applications of Damen Multi Cat vessels in general are towing and pushing operations, dredging support, harbour maintenance, buoy and anchor handling, deck and/or liquid-cargo transport and pollution control.
Mr Jason Schofield, Managing Director of Green Marine, says: “Damen’s short delivery time – just over one month – was crucial to us. The order was placed on 16 March and we were able to take delivery of the workboat on 22 April, so we could start our job for Andritz Hydro Hammerfest straight away. Also, Damen’s solid reputation in the industry and the fact that the vessel has a high residual value and good fuel efficiency, made us opt for Damen.There’s been an excellent relationship with mutual trust between all parties. Future cooperation between Green Marine and Damen Shipyards is more than likely.”
