Magma Global has delivered the world’s first high-pressure composite riser pipe to HWCG’s storage location on the U.S. Gulf Coast on May 14, completing its rapidly deployable Offset Flexible Riser (OFR) system.

HWCG commissioned Magma Global, manufacturer of PEEK and carbon-fiber composite m-pipe, to qualify and manufacture a high pressure, high temperature m-pipe to be used as a flexible riser connection to enhance HWCG’s rapid deployment emergency well containment system. The lightweight, flexible m-pipe section will provide additional flow and capture emergency response options for HWCG’s members in the U.S. Gulf of Mexico.

The m-pipe is designed for rapid installation and is suitable for responses where vertical access is restricted and an offset is required such as: shallow water depths where the presence of combustible and volatile compounds affect personnel safety or where access under a floating production facility is needed. The system may also be used in deeper waters where more flexibility is desired in managing the marine systems during a response.

Deployed straight from the handling apparatus, the 800 ft long section of m-pipe will provide a flexible riser connection between the capping stack placed on the incident well and a rigid riser suspended from a MODU. The m-pipe will form a horizontally oriented “S” shape between the capping stack and the rigid pipe riser thus decoupling motion and decreasing surface station-keeping requirements for the temporary production facility. Once in operation, hydrocarbons released from the well flow through the complete riser flow path and are processed on board the temporary production facility to be collected in shuttle tankers for transportation.

HWCG specified a pipe that would need to be compliant with movement and resistant to degradation from continuous exposure to hydrocarbons at pressures up to 10,000 psi and temperatures up to 250°F and would offer an alternative to conventional non-bonded flexible pipe. Magma qualified the six-inch m-pipe to meet the project requirements and completed manufacture and FAT testing during the COVID-19 pandemic lock-down.

HWCG is one of two deepwater oil and gas emergency response consortiums established for the U.S. Gulf of Mexico following the Macondo blowout incident in 2010. HWCG’s response provides for the installation of a capping stack within 7-14 days and the ability to commence contingent flow and capture operations within 18 days assuming no weather or other uncontrollable delays. Once installed the m-pipe is qualified to operate for at least six months, which is enough time to drill a relief well to provide final well kill and containment.

“This is a bittersweet success for Magma,” Martin Jones, CEO at Magma Global, said. “We are proud to supply the first composite flexible riser for high pressure, high temperature hydrocarbons, for use in the Gulf of Mexico yet we hope it will never have to be used. Nevertheless, m-pipe doesn’t corrode or degrade over time and hence will always be ready to enable HWCG to install at speed and with confidence.”
