Spoolable Composite Tubular Applications
Applications for spoolable composite tubulars can be divided into three major areas — onshore, offshore and downhole. Onshore applications, which include production and gathering lines that convey fluids between wells and surface facilities, are well-suited to spoolable composite tubing and RTP. Offshore appli

Other Applications Expand
A growing area in the offshore world is the refitting or “recycling” of older oil platforms to support additional production. A particularly active area for recycling is in the North Sea, where additional pipelines can be run to existing rigs for about $1 million (as opposed to spending $20 million for a new r

Material Selection And Properties
The design process starts with determining the functional requirements of the component part. These requirements include: • Mechanical properties — tensile, compressive and flexural strength; elongation, impact resistance, hardness, density. • Electrical properties — dielectric strengt

Studies Support Viability Of Composites
Numerous studies have compared the performance and cost of steel and composite tendons. Conoco, Norske Conoco A/S (NCAS) and KOP headed several projects to qualify composite TLP tethers prior to launching a full sea test. In a recent study, they compared steel and composite TLP systems in water depths up to 9,
