Innovative accommodation ship bridges gap between SOVs and CTVs
The SATV concept enables turbine technicians to remain at sea for up to seven days but does not need an offshore access system

A leading operator of crew transfer vessels for the offshore wind energy industry is to manage an innovative, purpose-built service accommodation and transfer vessel chartered for use on a Taiwanese windfarm.

The 35-m service accommodation and transfer vessel (SATV) is being chartered by Siemens Gamesa Renewable Energy for use on the Formosa 1 offshore windfarm off the coast of Miaoli County in Taiwan.

It will operate from the port of Taichung during the operations and maintenance phase of the offshore windfarm, starting in Q4 2019.

The vessel is capable of remaining offshore for at least seven days and will have 12 single cabins for wind turbine technicians. The vessel will be registered under the Taiwanese flag and manned by Taiwanese crew trained by Njord Offshore.

Njord Offshore managing director Tom Mehew said the SATV was a significant milestone for the company’s footprint in the offshore wind market and provides “a new logistical model” which will enable technicians to be accommodated offshore and transfer directly onto turbines without the need for an offshore access gangway. “Ultimately this will save time and money,” he said.

“With the SATV, we’re offering a new offshore wind service solution which demonstrates our commitment to meeting our customers’ needs and reducing the cost of energy from offshore wind. The concept fits the bill perfectly for projects like Formosa 1 – a full 40-person service operation vessel would be oversized, and standard crew transfer vessel, which would have to return to port every night would be undersized.

Siemens Gamesa head of maritime and aviation solutions Rene Wigmans said the SATV “will also allow us to safely and efficiently address the challenging tidal conditions in the Taiwan Strait.”
