Ocyan and Magma Global today signed a new MOU (Memorandun of Understanding) that guarantees the participation of BrasFELS in the CompRiser® solution, a riser tower system that utilises carbon fibre composite pipes. BrasFELS, located in Angra dos Reis, is the Brazilian shipyard of Keppel Offshore & Marine, the global leader in offshore rig design, construction and repair, ship repair and conversion, and specialised shipbuilding.
“The BrasFELS participation in the CompRiser® development is another achievement of this initiative. The shipyard location, its installed manufacturing capacity and reputation in the Brazilian market further reduces the project risk assessment. It’s certainly a partner that aggregates a lot of value”, explains Marcelo Nunes, Ocyan Director – Subsea Services.
Tony Duncan, Executive Vice President at Magma Global, said: “The CompRiser is an effective solution for deepwater and pre-salt environments. It’s a clever design that uses m-pipe in a static application thus streamlining the qualification needs versus dynamic riser designs. Confirming BraFELS as the manufacturing location means we can bring this design project to fruition in the very near future.”
Mr Marlin Khiew, CEO and President, Keppel FELS Brasil, said, “BrasFELS is the most established shipyard in the Latin American region, with a strong track record in the construction, integration, upgrading and repair of a wide range of products. We are proud to collaborate with Ocyan and Magma Global in the development of the innovative CompRiser® solution, which will strengthen the position of BrasFELS as a one-stop provider of solutions for deepwater production platforms.”
CompRiser® is a hybrid riser system created in partnership with Magma Global for use in the deepwater and ultradeep water oil exploration industry. The Thermoplastic Composite Pipe (TCP) used in the CompRiser® will be m-pipe®, manufactured by Magma. TCP provides high corrosion resistance (e.g. CO2 and H2S), of great value to the subsea systems at the pre-salt area, significant weight reduction and the possibility of withstanding high temperature and pressure. Its mechanical flexibility allows the design of a new concept for the lower termination (patent pending) that allows the riser to be connected directly to the flowline – both rigid and flexible.
Its compact and modular manufacturing method allows high local content. Additionally, m-pipe is delivered in reels and does not require welding, simplifying the bundle assembly which can be completed in less than 30 days. The offshore installation takes another 20 days, without the need for special vessels and with minimal exposure to bad weather conditions.
As a decoupled solution, the product uses less than 20% of the load applied by other solutions in the production units. The result of this difference can exceed 9,000 tons per FPSO, conditioned to quantity of project risers. The reduction of weight and load in the FPSOs (floating production storage and offloading) operations is a constant demand of the operators.
