Wärtsilä Ship Design reports that a second confirmed design contract for its new series of Arctic platform supply vessels has been signed.

The latest order is for a multi-purpose PSV being built by Tersan Shipyard in Turkey on behalf of US-based Tidewater, for a scheduled 2016 delivery date. It will be operated by Tidewater subsidiary Norwegian Troms Offshore Supply Group. The contract includes an option for further three vessels.

The 89.1m long ship is to the VS 4530 MPSV design, and will be built to DNV ice class ICE 1A. It will be powered by three 8L26 engines, each rated at 2,720 kW, driving two 3,000kW azimuthing thrusters for main propulsion. Also included in the Wärtsilä scope of supply are tunnel thrusters and retractable thrusters, ballast water system and inert gas generators.

According to Wärtsilä, the contract was awarded on the basis of Tidewater's requirement for a compact design with a high deadweight giving maximum cargo capacity. Operational efficiency and reduced fuel consumption were among other reasons why the Wärtsilä solution was selected. The ship will be prepared for fitting a 150t AHC offshore crane and a helicopter deck, giving it potential to carry out subsea construction tasks.

"Once again, Wärtsilä Ship Design's deep understanding of the complexities involved in operating in the harshest climatic conditions, and its ability to produce a design that fully meets the customer's expectations has been rewarded with a significant order. Wärtsilä's total solution capability, combining a strong and efficient design with fuel saving propulsion, is increasingly important in the market for ice class vessels," said Riku-Pekka Hägg, vice president, ship design, Wärtsilä Ship Power.
