m-pipe® applications and benefits
m-pipe® is a high performance composite pipe ideal for use in reliable subsea production systems due to its light weight, high strength, high flow rate capability and resistance to corrosion, chemical attack and fatigue loading. The inherent benefits of m-pipe® have the potential to simplify subsea piping design and architecture. Critically, m-pipe® also simplifies subsea installation procedures and operational activities, to drive improvements in long term reliability, such as 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 well intervention vessels. 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.
m-pipe® is suited to subsea tiebacks to meet high pressure, deep water application, gas lift, water injection or hydrocarbon transfer requirements. The light weight, flexibility and strength of m-pipe® greatly simplifies the design process and installation activities that follow on from deployment, pull-in and subsea connection phases. Installation loads are greatly reduced compared to steel and NBF pipe, allowing the use of smaller vessels and faster operations with minimised interface loads. The flexibility of m-pipe® allow it to be readily deflected to fit with light loads. This eliminates the need for precise metrology and accurate fabrication, simplifying offshore operations and reducing schedule-critical activities.
Once installed, m-pipe® has a high fatigue performance to resist subsea motions, can cope with HPHT conditions, is highly resistant to degradation and does not corrode due to the action of salt water or sour service. Its smooth bore enables high flow rates and low pressure drop, and the smooth PEEK surface is resistant to wax and hydrate build-up and erosion, with better overall performance than clad stainless steel. m-pipe® tiebacks can also be insulated, using conventional subsea materials, or designed to utilise active heating through the carbon fibre, to assist with flow assurance.
