PORTSMOUTH, UK – Ocyan and Magma Global have signed a memorandum of understanding under which BrasFELS will participate in the CompRiser development.

This is a riser tower system that employs carbon fiber composite pipes.

BrasFELS, based in Angra dos Reis, Rio de Janeiro, is the Brazilian shipyard of Keppel Offshore & Marine.

“The shipyard location, its installed manufacturing capacity and reputation in the Brazilian market further reduces the project risk assessment,” said Marcelo Nunes, Ocyan director – Subsea Services.

Tony Duncan, executive vice president at Magma Global, said: “The CompRiser is an effective solution for deepwater and presalt environments. It…uses m-pipe in a static application thus streamlining the qualification needs versus dynamic riser designs.

“Confirming BrasFELS as the manufacturing location means we can bring this design project to fruition in the very near future.”

Marlin Khiew, CEO and president, Keppel FELS Brasil, added that CompRiser would “strengthen the position of BrasFELS as a one-stop provider of solutions for deepwater production platforms.”

Magma will manufacture the m-pipe thermoplastic composite pipe, which is said to provide high corrosion resistance to carbon dioxide and hydrogen sulfide, suiting presalt area subsea systems, also providing a substantial weight reduction and the possibility of withstanding high temperature and pressure.

Its mechanical flexibility is said to facilitate the design of a new concept for the lower termination that allows the riser to be connected directly to the flowline, whether rigid or flexible.

In addition, the compact and modular manufacturing method suits local fabrication, and the fact that m-pipe is delivered in reels and does not require welding is said to simplify the bundle assembly which can be completed in less than 30 days.

Offshore installation takes another 20 days, Magma added, without the need for special vessels and with minimal exposure to bad weather conditions.

Finally, as a de-coupled solution, the product is said to take up less than 20% of the load applied by other systems in the production platform, with consequent weight reductions.
