Abstract
A method, system and apparatus for deploying a subsea well intervention system from a surface vessel to a subsea tree, including connecting a spoolable compliant guide (SCG) to a subsea intervention package; testing the connection; lowering overboard the intervention package into a water column using a primary lifting device; 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, 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 a 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.
