Riser, jumper and flow-line solution for subsea environments

fatigue and corrosion solve many of the problems that riser designers are currently struggling to accommodate with current steel and flexible solutions. I believe the new technology developed by Magma will reduce risk and installed cost of riser systems – the time has finally come for the use of this type of material in the offshore industry.” “m-pipe’s light weight, high performance design, combined with the ability to spool long continuous lengths will provide the industry with some exciting and highly cost effective solutions,” commented John Mair, technology development director at Subsea 7. “Working with an installation contractor from the start will ensure efficient and safe deployment, reduced risk and reduced cost particularly in deepwater deployments. We see this as a potentially exciting technology for the industry.”

manufacturing process. Pipe diameters up to 15" can be spooled for storage, transport and deployment. “We believe with the development of m-pipe we can deliver risers and flow- lines that offer significant performance improvements over incumbent technologies in key areas such as weight, fatigue and long term reliability,” commented Martin Jones, CEO at Magma Global. “With the offshore industry now operating in deeper water and more aggressive environments, m-pipe offers significantly increased pipe-line safety factors and decreased risk associated with deep water subsea extraction of oil and gas.” As a result of m-pipe’s light weight, fatigue performance and strength, engineers are able to take a fresh approach to riser architectures. “m-pipe offers the potential for a significant improvement in the way we design, manufacture, install and operate critical riser systems,” said Steve Hatton, principal director, 2H Offshore. “Its weight and high resistance to

m-pipe™ is a high performance carbon and polymer pipe developed by Magma Global Ltd in response to the challenges of deepwater, sour service, high pressure, high temperature and highly dynamic subsea applications. The company claims that m-pipe offers improved reliability, increased performance, and longer life than conventional un-bonded flexible pipes or steel solutions in the following ways: strength to weight performance – an m-pipe™ riser weighs one-tenth of a steel or un-bonded flexible riser in water; sour service performance; operational temperatures up to 350°F with no degradation in fatigue or corrosion performance; low thermal conductivity; lower flow-resistance than steel or un-bonded flexible solution; better erosion resistance and damage tolerance than steel; and no fatigue operating within specification. With internal diameters between 2" and 24", m-pipe can be produced in continuous lengths through Magma’s highly automated and controlled

Screw caps with sealing ring Pöppelmann GmbH & Co KG has added a new screw cap to its Kapsto ® range. The GPN 804 protects and seals outer threads of pipes and tubes, as well as connectors on components. Sealing-rings made from mechanical and chemical resistant elastomer are inserted into the screw caps.

The company says that this is a viable alternative to the standard product GPN 800 for use during storage, transport, assembly and finishing processes where a heightened protection against ingress and discharge of liquids is required. A non-slip knurling on the outside of the cap aids quick and easy fitting and removal. The yellow caps are made from largely chemical and impact resistant PE-HD (polyethylene high density) and are available in most established metric threads, a variety of American standard and fine threads, and certain pipe threads. Additional sizes as well as heat resistant types are available on request.
