Description
Technical field
The invention belongs to the technical field of submarine cable waterproof sealing, and in particular to a kind of FPSO single-points submarine cable head is prevented
Watertight encapsulation method.
Background technology
STP systems are the permanent mooring gears of a set of Floating Production Storage emptying ship (FPSO), and the FPSO of institute's mooring is
One nothing can carry out crude oil production operation and storage unloading operation from the newly-built oil tanker of the ability of boat.At regular intervals, it is outer defeated to wear
Mooring on FPSO, is passed through defeated stored crude oil outside the defeated mode of stern by shuttle oil tanker.STP systems have complete weathercock effect
Passive turret system, it by Single-point system by the power Transmission of FPSO independent power generations to two production platforms nearby, together
When the oil gas of production platform is transferred in FPSO single-points by submerged pipeline so that be transitioned on FPSO carry out oil gas water at
Reason.Carried out large repairs because FPSO needs to move dock to, so FPSO Single-point system needs to free work.Starting to free must before operation
Following several preparations must be performed：Pipe-line system is needed to rinse, and cleaning, release, draining is pulled down from swivel joint；In addition,
Flexible pipe on rotary slip ring, junction box, pipeline, cable and annex are required for pulling down；The equipment of STP floating drums need to be pulled the plug
Carry out waterproofing protection.Dragged away because FPSO departs from this, the seabed that originally submarine cable at this will be sunk to herein is carried out
Preserve, so the cable is accomplished by carrying out waterproof sealing, and the quality of cable waterproof is to ensure that can dock normally answer after dock repair
The important step of production.Existing cable waterproof technology is by adding waterproof filler, mackintosh and thermal shrinkable sleeve Multiple Superposition bag
The mode of bundle, not only waterproof sealing effect is not good, expend material, and complex steps, to disassemble process complicated, it is difficult to meet now
Offshore oil complex environment situation.
