摘　　要：海洋石油111FPSO单点配重块丢失严重,利用配重链替代丢失的配重块,并且实现了在线维修。更换后,有效地降低了FPSO运动对系泊锚链本体的冲击负荷;同时,在维持系泊惯性矩不变的条件下,弥补了配重块在极端海况条件下容易丢失的缺陷。Because of Serious loss of weight block in HYSY 11 IFPSO single mooring system, anchor chain is used to replace missing blocks with online maintenance. After replacement, the FPSO movement is reduced effectively, while in the conditions of keeping the mooring inertial moment, when the counterweight easilylost in extreme sea conditions the defects is made up.
