A conference & awards Winner Offshore Renewables Award
The winner of the offshore Renewables Award was Sea Installer, a highly specified turbine installation vessel that recently started work for A2SEA

several other similar vessels was Sea Installer. Sea Installer started work in December 2012 on the Gunfleet Sands project offshore the UK, loading two Siemens 6 megawatt (MW) test turbines, after which the vessel was due to join Sea Power, Sea Worker, and Sea Jack on the installation of wind turbine generators on the Anholt windfarm, offshore Denmark. The vessel, which is based on a design from GustoMSC, is fully self-propelled, is fitted with accommodation for two full installation crews, and is designed to work in three main modes, the first of which is as a floating crane vessel, with restricted crane loads; the second is when semi-jacked up, with reduced load on the legs, for harbour use and on sites with difficult soil

conditions; and the third is fully jacked up. “We have focused on making a vessel with
excellent crane position in order to maximise the usage of the deck area and minimise handling of the cargo onshore and offshore,” said A2SEA, noting that the vessel is built for operation in tidal areas and difficult soil
conditions. The design of the vessel also incorporates A2SEA’s many years of experience with the rest of its fleet. Turbine
components are loaded onto
the deck of Sea Installer directly from the quayside and stored there until the vessel reaches its destination offshore. The deck area of the vessel is 3,350m2, and has been specially designed for wind turbines in order to maximise the use of available space. As a result, the four jack-up legs are cylinder shaped/round instead of the conventional triangular shape, and this saves a large amount of space. The crane used to lift wind turbine components on and off Sea Installer is
