FIELD: pipeline engineering. ^ SUBSTANCE: device for coupling with vertical pipeline comprises vertical pipeline for transporting oil and/or gas from sea bed to the sea platform that receives flexible pipe connected with the transporting pipeline. The vertical pipeline is made of reserve vertical pipeline. The coupling mounted at the top and bottom end of the reserve vertical pipeline provides a seal between the transporting pipeline and flexible pipe. ^ EFFECT: reduced cost. ^ 3 cl, 6 dwg |
