New concept delivers optimum comfort and workflow

A new concept in Service Accommodation Transfer Vessels (SATV) has commenced operations in Taiwan immediately after completing an extensive sea trials program.

The latest BMT-designed SATV, one of over 55 BMT-designed windfarm support vessels around the world, is now on long term charter for Siemens Gamesa Renewable Energy as part of the Formosa 1, Offshore Wind Farm Project.

The pioneering design of the 36m SATV makes it the first vessel of its kind. Plugging the gap where a full size SOV (service operation vessel) would be unsuitable and too expensive, the advanced design offers  greater operational versatility; providing long term offshore accommodation while still being able to push up against the turbine to transfer technicians.

The SATV uses the new third generation of BMT’s patented Active Fender System™ to land on wind turbine generators, the significantly reduced impact load enables the safe transfer of service technicians onto the towers. Passenger comfort is enhanced with all sleeping accommodation situated in a resiliently mounted super structure above the main deck where noise levels will be kept to a minimum, a first for a transfer vessel of this size.  Ten crew are able to stay onboard for 12 day offshore endurance.

The hull form is based on BMT’s ModCat range which offers improved seakeeping performance, but with a minimal resistance penalty, complemented by a full active ride control system. Powered by twin MTU 16V2000 engines that are coupled with a CPP propulsion system (supplied by Servogear), to optimise fuel efficiency during different modes of operation. The new 36m SATV will travel at a sprint speed of 20 knots and cruise at a speed of 16 knots, with a deadweight capacity of 75 tonnes.

Chris Witty, Technical Lead for Specialised Ship Design at BMT comments, “It’s fantastic to be a part of continually developing Offshore Renewables industry, particularly with such exciting projects like the SATV. The design brief really allowed us the freedom to devise the optimal configuration, from both a comfort and a workflow perspective.”
