Magma Global’s launch of m-pipe™ at OTC Houston reaffirmed the need for a high performance carbon and polymer pipe to meet the challenges of deepwater, sour service, high pressure high temperature and highly dynamic subsea applications.
“We were delighted at the industry’s response to m-pipe™,” remarks Damon Roberts, Magma’s Engineering Director. “It’s performance advantages over steel and un-bonded flexible pipes seem to resolve a number of specific problems facing existing fields, and many proposed developments, which face challenges with high pressures, high temperatures and sour service. Many of the teams visiting our stand during the show were articulating specific problems they were facing where m-pipe™ could provide the ideal solution.”
In addition to solving specific problems within existing architectures, many saw m-pipe™ as enabling new, more efficient and more reliable architectures. Particular focus was placed on the advantages resulting from m-pipe’s light weight when looking at deepwater configurations. m-pipe™ is around 1/10th the weight in water of an equivalent steel riser which has significant advantaged when it comes to reducing hang off loads.
Many see challenges with m-pipe™ in an SCR (Steel Catenary Riser) configuration, the general consensus being that it would require weighting at the touch down zone. A popular alternative was to look at the Compliant Vertical Access Riser (CVAR) configuration. Here m-pipe™ benefits in terms of fatigue and weight present distinct advantages.
Stuart Mitchell, Chief Executive of Flexlife, specialists in full field subsea project and integrity management, was quick to recognise; “Flexlife has a track record in delivering robust but novel solutions to the oil industry, and m-pipe™ offers some significant benefits which should enhance the solutions we are able to deliver our customers. This is definitely a game changing technology for deep water riser configurations.”
“m-pipe™ offers the potential for a significant improvement in the way we design, manufacture, install and operate critical riser systems,” comments Steve Hatton, Principal Director 2H Offshore. “It’s weight and high resistance to 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.”
For deepwater applications, the combination of m-pipe’s lightweight and spool-ability appealed to many from the deployment perspective. The ability to significantly reduce deck loads and speed up deployment through a combination of simpler configurations and spooled deployment was seen by many as significantly reducing deployment risk and reducing deployment costs. Magma has worked on its first deepwater deployment configuration with Subsea7 to produce a faster, lower risk and lower cost deployment method.
“We see m-pipe™ as a potentially exciting technology for the industry. Working with an installation contractor from the start will ensure efficient and safe deployment, reduced risk and reduced cost particularly in deepwater deployments,” John Mair – Technology Development Director at Subsea 7.
