Wärtsilä Ship Designs has won a contract to design six offshore oilfield ships for China Oilfield Services Limited (COSL).

Under the contract, which was signed this month, Wärtsilä will supply COSL with two Platform Supply Vessels (PSVs) and four Anchor Handling Tug Supply (AHTS) vessels. The vessels, which will be used by COSL to provide support operations in the South China Sea and Bohai Bay, will be constructed based on Wärtsilä’s VS 485 PSV MKII and VS 4612 AHTS designs.

The PSVs will feature an optimised hull to reduce emissions and allow for greater efficiency. The AHTS will also be highly efficient and environmentally friendly and have been designed to withstand challenging sea and weather conditions.

Ove Wilhelmsen, managing director of Wärtsilä Ship Design, told The Motorship: “Fuel economy and environmental friendliness have been some of the most important design criteria during the development of the VS 485 series which has become a very popular vessel in the global oil and gas industry.”

“The AHTSs will be equipped with state of the art power and propulsion systems and will perform as the most modern and sophisticated AHTSs in the world.”

“Our most recent project with COSL is the Hai Yang Shi You 708 which was delivered in December 2011. The deep water survey vessel has been a great success for all parties. A positive experience which we’re sure we will repeat this time,” he added.

Construction of the vessels will start in 2013 and is expected to be completed in 2014-2015.
