FIELD: mining. ^ SUBSTANCE: invention includes arrangement of the first vessel over hydrocarbon well, fixation of pipeline to pump hydrocarbons at the first vessel to the first end fixed to launching gear at the first vessel, fixation of the second end of pipeline to the second vessel arranged near the first vessel, pipeline lowering with the help of launching gear, increasing distance between the second vessel and the first vessel after displacement of the second vessel in direction of the third vessel anchored at the distance from the first vessel, and pipeline drawing until the second vessel is not near the third vessel. Provision of pipeline section contact with sea bottom at the position between the first and second ends of pipeline, displacement of the second end of pipeline at the distance from the first vessel, in direction of pumping pipe length, exceeding distance between the first vessel and anchor position of the third vessel, return of the second end of pipeline to anchor position of the third vessel, and establishment of hydraulic link of the second end of pipeline with the third vessel. ^ EFFECT: invention eliminates necessity of using special pipe-lay ships, makes it possible to accurately control angle of incline in pipelines that connect underwater deposit to a platform, fixed to surface vessel or to submersible buoy. ^ 14 cl, 18 dwg |
