A METHOD OF DRILLING OR EXPLOITING A WELL USING AN OFFSHORE PLATFORM AND A RISER SUBJECT TO WATER CURRENT

摘要

A method of drilling or exploiting a well (12) using an offshore platform (16), and a riser (19) intended to extend along a vertical direction (V) between the platform and a seabed (14) and subject to a water current (F). The water current applies mechanical efforts on the riser. The method comprises the step of applying compensation mechanical efforts (F1 ) on the riser, wherein the compensation mechanical efforts have a static horizontal component (R) intended to be the opposite of a horizontal net force (R') of the mechanical efforts applied by the water current.
