Title:
APPARATUS AND METHOD FOR TREATING SUBSEA FLUID CONDUITS
Document Type and Number:
WIPO Patent Application WO/2015/150837
Kind Code:
A3
Abstract:
An apparatus and method for collecting fluid during flushing of a subsea fluid conduit such as a subsea umbilical. The apparatus comprises a vessel configured to receive fluid from the subsea fluid conduit, and a first connector for fluidly coupling the vessel to the subsea flowline. In one aspect, the apparatus comprises a second connector for fluidly coupling the apparatus to a subsea production system and a flow control system. The flow control system is configured to operate in a first mode in which flushing fluid is directed from the subsea fluid conduit into the vessel, and is configured to operate in a second mode of operation in which the fluid is diverted from the subsea flowline to the subsea production system. In another aspect, the apparatus is configured to provide a detectable signal to surface when a pre-determined volume of flushing fluid has been received in the vessel.
