    Vessel & ROV News // January 14, 2015

    28 December saw the first example of a new design from Skipsteknisk in Norway, the ST-263, handed over to China Offshore Oil Engineering Company (COOEC), a subsidiary of CNOOC.

    The ST-263 is a sophisticated multipurpose offshore construction vessel, developed by Skipsteknisk in close cooperation with COOEC. The vessel was built by CSSC Huangpu Shipyard in China, and is named Hai Yang Shi You 286.

    This is the first ST-design for COOEC, but the third ST-design developed and delivered for CNOOC.

    The ST-263 has an overall length of 140.75m, moulded breath of 29m and a depth of 12.8m, a working deck of about 1,900m2, accommodation for 150 people and is fitted with a helicopter deck for S92.

    The vessel is designed as an IMO DPS3 vessel under double class CCS and DNV, for extreme operations at water depths down to 3,000m. HYSY286 is equipped with a working moonpool of 7.2m x 7.2m amidships, suitable for a VLS operations; a 400 tonne mast-type AHC crane plus a 50 tonne offshore crane for subsea operations. It also has a 2,500 tonne carousel under the main deck for flexible pipe, umbilical cable, power cable; 250 tonne A/R AH winch for mooring operations; and two 3,000m-rated work-class ROVs in dedicated hangars.

    The ST-263 is also prepared for installation of an A-frame at the stern and for SAT diving operations.

    Skipsteknisk is currently also working with CNOOC's subsidiary COSL, designing two ST-259 OCVs, a ST-318 and a ST-315 seismic vessel. These vessels will be delivered in 2016.
