TCP concept and benefits

The Thermoplastic Composite Pipe (TCP) concept excels in simplicity. The solid wall consists of an inner liner, thermoplastic composite reinforcement layers and a protective outer coating. Optionally a weight coating can be applied to ensure on-bottom stability. All layers, including the outer coating, are melt-fused together ensuring a bond between the layers that is as strong and durable as the base materials. The TCP is terminated by the end-fitting that effectively engages on the outer coating; the pipe can be terminated at any point of the pipe, onshore and offshore, in a matter of hours.

We design the TCP, and select the materials based on the specific requirements of each project, ensuring that a fit-for-purpose and cost effective solution is offered – every single time. Being material independent, we only use ductile, flexible polymers that do not suffer from micro-cracking, can be bonded onto the pipe as coating as well and that enable a small bending radius of the pipe during installation and operation. An overview of materials used is shown below.

  • Lowest permeation
  • Highest chemical resistance

TCP end fittings

The solid pipe wall enables the use of simple end terminations that can be made up within hours at any location in the world. The proven clamping method avoids having to terminate individual reinforcement layers and can be applied at any point in a pipe. Our products can be terminated (essentially, cut to size) offshore, permitting small I-tube diameters and providing the ability to adapt the final length offshore.

The end-fitting consists of a metal composite interface and a client-specified flange. Flange systems available today include API, ANSI and compact flanges. We supply in a variety of materials including carbon steel, 316 stainless steel, super duplex and inconel. All our end-fittings can be equipped with ancillaries, such as bend restrictors or bend stiffeners.

TCP benefits

The ability to offer the best material for each application has a proven and significant impact on pipe material cost and ensures that the lowest cost solution is selected for each project. The unique character of the TCP technology offer specific benefits:


  • Able to handle high pressure up to 15,000 PSI or 1,030 bar
  • No corrosion, resistant to H2S, CO2 and seawater
  • Lengths of up to 4 km possible, continuous lengths limited only by reeler or carrousel capacities


  • Lightweight, enabling installation using small vessels
  • Easily installable end-fitting allowing for in-field termination
  • Spoolable


  • Smooth bore enabling high flowrates
  • Collapse resistant
  • Superior fatigue resistance
  • Extremely durable, due to unsurpassed toughness, impact resistance and residual strength
  • Easy repair of superficial damage due to robust external coating layer

Our products outperform existing solutions in terms of durability, corrosion resistance and total cost of installation. Further cost reductions are possible by capitalising on the knock-on effects of using TCP. These include reducing total cost of ownership due to its durability and corrosion resistance, optimising FPSO designs to exploit the benefits of the significant top-tension reduction, and many other opportunities.
