Patent ID: 8316947

Claim:
A method for deploying a subsea well intervention system from a single surface vessel to a subsea tree, comprising: connecting a spoolable compliant guide (SCG) to a subsea intervention package on a deck of the vessel; testing the connection on the deck of the vessel; lowering the intervention package into a water column using a primary lifting device disposed on the surface vessel, including a winch or a crane, such that the SCG does not support a weight of the intervention package; gradually paying out the SCG from a reel thereof as the intervention package is lowered to a seabed; transferring the weight of the intervention package to a secondary lifting device disposed on the surface vessel, including a winch or a crane, wherein the intervention package functions as a dead weight to overcome a positive buoyancy of the SCG, a distance between the primary and secondary lifting devices creates and controls a shape of the SCG; and once landed onto the subsea tree with heave compensation, disconnecting the secondary lifting device from the intervention package, and hanging the SCG off at the vessel at deck level.
