Light well intervention umbilical and flying lead management system and related methods

摘要

Systems and methods for managing umbilical lines and one or more jumpers are provided. An example of a system includes a deployment platform carrying a winch and spool assembly, a tether management assembly, and an integrated electrical and/or hydraulic umbilical line extending between a spool on the winch and spool assembly and the tether management assembly. The winch and spool assembly is configured to deploy and to support the umbilical line. The tether management assembly includes a winch and spool assembly for deploying a flying lead and/or annulus jumper adapted to connect to an emergency disconnect package of a well control package for a well. A set of buoyant modules are connected to or integral with a portion of the umbilical line to be used to form an artificial heave compensation loop.

主权项

1. A method for providing control and well kill capability during a subsea light well intervention, the method comprising the steps of:
connecting a sea-bound end of an umbilical line to a tether management assembly, the tether management assembly including a connector for operably coupling the sea-bound end of the umbilical line to a jumper, and a jumper spool assembly carrying the jumper; running the umbilical line from an umbilical spool assembly located on a vessel, the umbilical spool assembly carrying the umbilical line; connecting an end of the jumper to a well package connector located on a well package of a subsea well to include paying out a sufficient amount of the jumper to reach the well package connector located on the well package; landing the tether management assembly at a seabed location substantially spaced apart from a location of the subsea well; and running a wireline from the vessel through a pressure control head connected to the well package of the subsea well, wherein the umbilical line at a location where the umbilical line extends from the vessel is substantially spaced apart from the wireline at a location where the wireline extends from the vessel.
