IDP hydraulic intervention system
m-pipe® subsea intervention animation
Magma m-pipe® is a high performance thermoplastic composite pipe suited to reliable subsea production systems due to its light weight, high strength, high flow rate capability and resistance to corrosion, chemical attack and fatigue loading. m-pipe® properties simplify subsea piping design and architecture and reduce project costs. Critically, m-pipe® also shortens subsea installation procedures and operational activities and drives improvements in long term reliability, with a reduced need for inspection, maintenance, repair or replacement.
m-pipe® is proven to substantially reduce subsea project costs and furthermore reduce subsea project deployment risk, for example through a reduction in the need for large riser buoyancy modules or the ability to use smaller light well intervention vessels rather than rigs in areas like the Gulf of Mexico. m-pipe® has a high strain capability ten times that of steel, plus an ability to accommodate axial compression loads without birdcaging or excessive fatigue damage rates. This allows m-pipe® to be deployed in simplified and lower cost subsea piping configurations that are not possible with steel or non-bonded flexible pipe, either due to weight or axial compression limits.
Downlines for hydraulic pumping
Coiled tubing evolved as a simple solution for hydraulic pumping in offshore wells, driven by a need for fast, mobile delivery. However, corrosive intervention fluids and increasing well depths that require high fluid flow rates and operating pressures, are taking coiled tubing beyond the limits of its capability. Coiled tubing reels are large and coiled tubing is prone to handling damage, plastic deformation, fatigue and chemical attack, necessitating regular replacement, reduced well intervention campaign efficiency and higher costs.
m-pipe® combats the operational fatigue and flow rate challenges of coiled tubing, providing efficient hydraulic pumping to rectify downhole issues rapidly and maximise a well’s commercial life. Magma has developed a 3,000m (10,000ft) 3in m-pipe® and IDP (Integrated Deployment Package) as a practical high flow rate hydraulic pumping solution up to 15ksi for offshore light well intervention, with the capability to withstand highly corrosive intervention fluids such as HCl.
Subsea Light Well Intervention (LWI) from small construction and support vessels is increasingly used to achieve increased commercial production from subsea wells on a cost effective day-rate basis, avoiding the need to mobilise costly MODU. m-pipe® is an ideal product to facilitate high flow rate pumping in a safe and reliable manner. m-pipe® has applications in IWOCS, downline and chemical injection systems, offering hydraulic LWI benefits due to the light weight of m-pipe®. The Magma compact IDP is suited to the back deck of smaller vessels for day-rate rental to operators and contractors.
m-pipe® offers minimum weight, maximum flexibility and proven ability to accommodate a wide range of stimulation fluids without degradation. Importantly, m-pipe® has a high fatigue performance, allowing multiple deployments over many years without concern of fatigue failure, avoiding the common performance issues of steel coiled tubing.
Magma has developed a complete IDP subsea intervention system in collaboration with back-deck specialist MDL, enabling rapid and efficient mobilisation onto a deployment vessel using a lightweight crane. The IDP comprises of a modular reeler with level wind, m-pipe® riser and handling system, built-in tensioner, control cabin, power unit, installation deck and retrieval winch, designed for rapid deployment and retrieval in deep water.
