New range of windfarm vessel designs

Fri, 30 May 2014

OSD-IMT, the UK division of Offshore Ship Designers (OSD), has developed a range of innovative new offshore windfarm service vessel designs.

Michiel Wijsmuller, managing director of OSD, said: “These new designs are based on the outcome of four years of extensive discussions with windfarm developers, operators and maintenance companies. They fulfil the operational demands of the windfarm maintenance industry and can also provide logistics support services to transformer platforms.”

The 1,350 dwt IMT972 SOV is powered by two Steerprop SP25 or equal 1900 kWe fixed pitch azimuth propulsion units.

There is also an option for fitting two 2.5MW Voith Turbo main thrusters. Frequency controlled electric motor driven CPP thruster units are fitted forward, comprising two tunnel type bow thrusters and one retractable bow thruster for station keeping and high dynamic performance under manoeuvring or DP conditions.

The main features of the IMT972 include a heave-compensated turbine platform and an aluminium access gangway arranged with a telescopic frame which facilitates the transfer of equipment to the platform.

A back-up evacuation process is arranged by using the workboat to transfer technicians from the turbine access ladder in an emergency.

The mono-hull workboat is fitted with a heave-compensated single point lift davit for general wind turbine work duties as well as for emergency evacuation of technicians.

There are two boat-landing areas, one starboard and one at the stern of the vessel. There is a large deck area arranged for additional equipment or the retrofitting of an ROV system for turbine tower or seabed inspection.

The IMT972 has an electro-hydraulic 1.0 tonne SWL motion-compensated folding jib crane fitted on a pedestal on the main deck aft of the access gangway tower. It accesses the wind tower platform when the gangway is stowed and can also work over the stern, deck area or ship’s side.

The air-conditioned crew facilities include a mess room and recreation room. It can provide accommodation for up to 60 persons, including 22 crew, and is able to operate for 30 to 45 days on station or longer if replenished at sea.

In addition to its role as a windfarm maintenance SOV, the IMT972 can be used as a standby rescue vessel, command/control vessel, survey vessel and ROV support vessel.

OSD is a one-stop shop delivering naval architecture and marine engineering skills to the shipping and offshore energy industries.
