Description
Product Description
Drilling risers are temporary offshore tubular systems used to connect the subsea wellhead and blowout preventer (BOP) to the surface drilling unit. They provide a controlled return path for drilling fluids and cuttings while enabling pressure control and well integrity during drilling operations.
Risers are designed to operate in dynamic offshore environments and are supplied with interfaces and features compatible with deepwater drilling systems, including auxiliary lines and motion-compensation equipment.
