Is reusability and composites are the way forward?
Thermoplastic composite pipe can change the economics of subsea production say two of the first manufacturers. An industry project aims to pave the way for cheaper qualification of such components
Industrial use of composites in which plastics are combined with other materials for added strength, flexibility, fatigue resistance or other desired properties is relatively matured in sectors such as aerospace. The Boeing 787 Dreamliner aircraft is a complete composite structure, for example.
In oil and gas, the past decade has seen a rapid advance in the qualification and application of thermoplastic composite pipe (TCP) to counter inherent drawbacks of steel: corrosion, fatigue and weight.
Of respondents to a DNV GL survey of industry leaders, 57% see a need for cheaper, more effective pipeline material in general, while the average cost of installing and maintaining a pipeline accounts for around 35% of a typical subsea tie-back project.
In today’s cost control climate, the industry now views TCP as a viable alternative to steel across project lifecycles. A growing variety of applications offshore include flowlines, risers, jumpers, expansion spools, and lines for uses such as access, chemical injection, choke and kill, commissioning and intervention.
Magma is already involved in first efforts to qualify TCPs following DNV GL’s Recommended Practice DNVGL-RP-F119 Thermoplastic composite pipes (2015) to assure performance, reliability and safety during a product’s lifetime.
