Abstract
A method of commissioning one subsea hydrocarbon well terminating by a wellhead, wherein, from a petroleum drilling rig, the method includes: screwing double-walled pipe segments together in mutual succession to form a thermally insulated floor-to-surface 1 hydrocarbons, and an outer pipe, between which pipes a thermally insulating material is disposed; connecting the floor-to-surface link pipe to wellhead; and extracting the hydrocarbons via the floor-to-surface link pipe to the drilling rig on the surface.
