A METHOD FOR RECOVERING FLUID FROM AN UNDERWATER APPARATUS SUBMERGED IN DEEP WATER

摘要

A method for recovering fluid from an underwater apparatus submerged in deep water, the method comprising the steps of flowing fluid to said underwater apparatus (BOP) to power the underwater apparatus, characterised in that the method further comprises the steps of flowing recovered fluid from said underwater apparatus (BOP) to a subsurface recovery apparatus (FRS) comprising a pump apparatus (430, 602) and selectively pumping recovered fluid to above a surface of the deep water. Preferably, the method further comprises a reserve capacity apparatus (410, 610) in said deep water, the method further comprising the step of allowing the reserve capacity apparatus (410, 610) to fill with recovered fluid.
