Installation and commissioning of the first 325 ton deep water vertical soft paving system in China

It is reported that this is the first set of deep water vertical soft paving system in China, with a maximum working depth of 3,000 meters. The equipment debugging of the deep water vertical soft paving system mainly includes mechanical hydraulic system, electrical control system, communication system, single machine debugging and system joint adjustment, etc., and has completed the installation and commissioning of more than 20 sets of mechanical equipment. Among them, it mainly includes 325 tons of tensioners, 36 tons of tensioners and 360 tons of moon pool covers.

The 325-ton deep-water vertical soft-pull system with good installation and commissioning can be directly invested in the next Wenchang 9-2/9—3/10—3 gas field group hose laying project to assist the development of Wenchang gas field.

The system is a 325-ton deep-water vertical soft-pull system purchased by Haohai Weima Investment from Shenzhen Offshore Oil Engineering Underwater Technology Co., Ltd. (hereinafter referred to as Offshore Oil Engineering Shenzhen Company).

The 325-ton deep-water vertical soft-paving system is advanced in technology and complex in structure. The multi-functional deep-water vessel “Offshore Oil 286” is used to support the mother ship. The main function of the system is hose laying, and the auxiliary functions are submarine cable and umbilical cable laying. The system can be laid with flexible pipe and cable products with an outer diameter of 50-630 mm, a maximum laying tension of 325 tons, an A&R system capacity of 400 tons, and an online structure installation capability.

The technical performance of the "Offshore Oil 286" ship has reached the world-class advanced level, with DP3 level dynamic positioning capability, equipped with 400 tons of heave compensation crane and two 3000 meters working ROV (underwater robot), the overall working water depth is 3,000 meters.
