What testing has been done on TCP by Strohm, both on material level and full scale?

Strohm tests TCP in full compliance with the standard DNV-ST F119. The testing covers both the material itself, as well as the full-scale product, as per the testing matrix outlined in the recommended practice. This can be summarized as follows:

  • The material is tested in the fluids it is used in, for short and long term, at the minimum and maximum design temperatures. This includes all long-term effects such as ageing, stress rupture and fatigue. Important is the fact that we test the material submerged in the fluid; for instance, NORSOK M710 hydrocarbon mixture, or methanol, seawater etc.
  • The full-scale testing confirms the accuracy of the design method by validating the design predictions. These tests include burst, collapse, bending fatigue, impulse testing and the like. In addition, Strohm have tested erosion, impact and fire jetting, all with great success.

What kind of certification does Strohm have on TCP?

For our subsea products, Strohm tests TCP in full compliance with the standard practice DNV-ST F119 and have the certifications for its design method, material, production method and first product TCP Flowline. On all our products, we provide the client with a Manufacturer’s Certificate of Conformity, certifying that the TCP we supply is in compliance to the standard practice DNV-ST F119.

How has Strohm qualified TCP for onshore applications?

We have tested and qualified our onshore product TCP Light in full compliance to API RP 15S standard.

How has Strohm qualified TCP for SURF and Subsea Well Intervention applications?

Strohm has qualified TCP in compliance with the standard practice DNV-ST F119 for TCP in subsea applications. This qualification includes product qualification, materials, design approach and production. To date, we have qualified TCP for permanent application in Flowlines and Jumper Spools for hydrocarbon service, methanol and MEG injection, chemical injection, gas lift and water injection. For subsea well intervention applications such as downlines and dynamic Jumpers, Strohm is fully qualified for pressure ratings up to 10,000 psi.

How is TCP designed, how can I review the design and become acquainted with the methods?

Strohm designs the TCP based on fundamental understanding of the behaviour of the constituents, the fibre and the polymer. In order to work with our clients on designing, we wrote a white paper on this subject, called Design and Qualification of Thermoplastic Composite Pipe. Please contact us to receive a copy of this document. It outlines the design and qualification method that we use. Further, in order to help our clients become more comfortable with TCP and its design, we do Lunch & Learns and we provide training on TCP design.
