Wärtsilä to Design 6 OSVs for China's COSL

Press Release
Wednesday, December 19, 2012

Wärtsilä signed a contract with China Oilfield Services Ltd (COSL) to supply the designs for a total of six new ships.

 

The two Platform Supply Vessels (PSVs) and four Anchor Handling Tug Supply (AHTS) vessels will initially provide support operations in the South China Sea and Bohai Bay. The contract was signed in December 2012.
The PSVs are based on Wärtsilä Ship Design's VS 485 PSV MKIII design that offers a highly energy and environmentally efficient vessel solution with an optimized hull design for greater efficiency, with corresponding reduced emission to air. The AHTS vessels are to be constructed according to the Wärtsilä Ship Design VS 4612 AHTS design. The primary function of AHTS vessels is to set anchors for drilling rigs, and tow mobile drilling rigs from one location to another. Since the sea and weather conditions in which these ships work is often extremely challenging, a design that offers reliability and high levels of efficiency and performance is called for.
