Composite Repair Keeps North Sea Oil Flowing

摘要

In the remote Shetland Islands, Clock Spring technology achieved the most cost-effective, worker-safe and environmentally sensitive repair of a landline section of the Ninian Pipeline, operated by BP Exploration Operating Co. Ltd.rnClock Spring coiled wrap is comprised of strong, lightweight fiberglass-reinforced isopoly-ester composite. Because of the way it is made, it has inherent "memory"rnthat constrains its shape to a cylinder of concentric layers around the area needing repair. The effect is similar to the physics behind the wound spring traditional clock.
