Mooring system is one of the要拿 most critical facilities in木有 FPSO technolog市錢y, which is called the "作討lifeblood" of FP做做SO. In the past, the design 呢家and manufacturing of FPSO mooring sys就購tem has been monopolized in the hand通工s of a few foreign companies. Once th長和e mooring system fails,南舊 it is necessary to hi吃拍re foreign technicians to provide費風 solutions, which is n視訊ot only very expensiv妹輛e, but also difficult to eff時兵ectively guarantee the oil field prod資暗uction time rate. The F行理PSO on-line anchor safety technolog刀化y has successfully broken the fo站電reign monopoly, which is of grea劇頻t significance.

On July 31, the reporter learn暗農ed that Shenzhen Bra師個nch of the Company Limite老西d (hereinafter refer外空red to as Shenzhen Branch) has succe制到ssfully completed the first onlin體刀e replacement of FPSO mooring sy兒習stem in China un個做der the condition that F坐說PSO is not released and山美 the oil field is not s了子hut down. In the early morning 說些of July 13, as the divers fastened th草見e connector to the last anchor chain 10說信5 meters underwater, the underwater mo文亮oring system compose腦花d of three groups of 9 mooring leg動刀s firmly "tied" the 150有為000 ton "offshore oil 111&qu路線ot; FPSO (floating product放市ion, storage and unloading遠小 device) to the sea surface.
