Abstract:
1. A method of well intervention in a subsea well having a wellhead on the sea floor, in which an intervention hose extends downwardly through the sea from a hose drum installed on a vessel on the sea surface into the well through a subsea intervention stack installed on the wellhead at the sea floor, and in which the intervention hose is exposed directly to the ambient sea between the vessel and the top of the subsea intervention stack, wherein the intervention hose is completely non-metallic or has a metal content of less than 50% by volume, wherein the hose is driven out of the well without the use of an injector by pulling the hose out of the well with the hose drum, wherein a guiding sheave for the hose is located at a position higher than the hose drum and is arranged to guide the hose into a downward direction towards the well, and wherein the hose extends substantially vertically on the drum side of the guiding sheave.
