China’s first self-built multi-functional offshore wind service operation Vessel(SOV) launched

Recently, a multi-functional offshore wind service operation Vessel(SOV) , independently developed by China State Shipbuilding Corporation’s Marine Design & Research Institute of China (MARIC), was launched Fujian Southeast Shipbuilding Company Limited, a subsidiary of Fujian Shipbuilding.

It is understood that the SOV is China’s first independent design, construction, with fully independent intellectual property rights of large-scale multi-functional offshore wind SOV, which fills the blank of China’s deep-sea cable laying and operation and maintenance.

It is a multi-functional SOV with wind power operation and maintenance equipment in the amidships, a cable working deck on the stern and an electric cable tray in the main hull, which is a giant “offshore mobile operation factory”. With an overall length of 94.9 meters, a beam of 22.8 meters, a depth of 9 meters, a design displacement of 9,497 tons and a range of more than 10,000 nautical miles, the SOV is classified by China Classification Society (CCS). It meets the requirement of unlimited navigation area and is equipped with DP 2 power positioning system.

The SOV features a number of functions such as sea cable repair, inter-area cable laying within the wind farm, wind farm maintenance, etc., and is capable of accomplishing a number of works such as fixed-point directional operation, flexible shuttling and fixed-point transfer of goods under adverse sea conditions.

The comprehensive performance of the self-built SOV is ranked top in China. Its configuration of offshore wind intelligent operation and maintenance system, cable laying operation system and burying plough and other core equipment, are localized.

It is capable of providing deep-sea O&M services for the offshore wind power industry, as well as marine cable laying and overhaul engineering services. Thus, It will effectively alleviate the problems of constraints on operation and maintenance of deep-sea wind power, poor accessibility of offshore wind turbines, poor sea conditions, etc., and provide high-efficiency operation and maintenance services for deep-sea wind power farms.

It is reported that the SOV has established long-term service customers before launching, with good market competitiveness, and will be mainly used for operation and maintenance of large-scale wind farms in deep-sea beyond 50 kilometers offshore and ocean engineering services.
