Conductor bend restrictor

摘要

An offshore system for drilling or production includes a buoyant hull. In addition, the offshore system includes a topside mounted to the hull and positioned above the surface of the water. Further, the offshore system includes a conductor having a lower end disposed in the sea bed below the sea floor and an upper end coupled to the topside. Still further, the offshore system includes a bend restrictor disposed about the conductor. The bend restrictor has a lower end positioned in the sea bed below the sea floor and an upper end positioned above the sea floor.
