BP, Subsea 7 join deepwater m-pipe initiative

Offshore staff

PORTSMOUTH, UK – Magma Global has signed a joint development agreement with BP and Subsea 7 to qualify Magma's carbon fiber m-pipe for the next generation of subsea pipelines.

The program has additional support from the UK’s National Composites Centre (NCC) and Innovate UK, the government initiative to support pioneering technologies in the energy sector.

Magma describes m-pipe as a high-strength, lightweight, corrosion-resistant, fully bonded, composite thermoplastic pipe manufactured from carbon fiber and PEEK polymer materials.

It is claimed to be is stronger than steel and traditional flexibles, and typically around one tenth the weight.

The new 30-month qualification program will target 6- to 12-in. pipes for risers and jumper systems in deepwater and includes laminate testing (elevated T and aged properties); single load tests (tensile, burst, collapse, bending, torsion, compression, impact); and combined load tests (axial bending, collapse bending, pressure bending, axial pressure bending).

One goal to open the way to lighter, more cost-efficient riser systems to drive down the costs of deepwater field developments, and in particular those with corrosive fluids.

Magma adds that jumpers or spool pipes made from m-pipe should be easier and less expensive to design and install, and more reliable to service.
