The Wuchang Shipbuilding Industry Group yard in China has delivered two new Wärtsilä designed anchor handling tug supply (AHTS) vessels to China Oilfield Services Ltd. (COSL).
The delivery of these two ships follows the success of the Wärtsilä designs for four AHTS and two platform supply vessels (PSV) delivered in 2015 to COSL and are now in regular operation.
"The six Wärtsilä Ship Design vessels in operation since last year are meeting all our expectations and we are extremely satisfied with them," said Cai Dian, vice general manager, COSL Shipping.
As a result of this satisfaction, COSL opted to deal directly with Wärtsilä for the design of the two new AHTS vessels.
The AHTS vessels are based on Wärtsilä Ship Design's VS 4612 design, and have been customized to meet COSL's operational requirements. The design features a reduced environmental impact and an optimized hull line providing lower fuel consumption.
The contract for the original six ship designs was placed in December 2012, and another for three new AHTS vessel designs in December 2014.
