摘要:
This concerns a method of connecting a subsea flowline to facilities on top of an offshore platform which is supported above a body of water and which has a plurality of conductors extending from above the water to within the sea bottom. One of the conductors is cut just above the mud line and raised to leave a gap between the lower end of the upper portion of the conductor and the conductor stub which remains firmly anchored in the sea bottom. The flowline is pulled to a position just adjacent said conductor stub. A production riser is lowered through the upper portion of the conductor and then the lower end of the production riser is connected to the pulled end of the flowline.
