m-pipe® reduces costs & improves ROI
How m-pipe® reduces subsea costs
m-pipe reduces subsea project Capex and Opex
Reduced oil price has put enormous pressure on Operator and supply chain CapEx and OpEx, resulting in a recent enthusiasm for subsea product standardisation and company mergers to drive subsea project efficiency.
But, with existing products, a Capex transformation is unlikely to be achieved safely and sustainably just by squeezing supplier margins. Once the oil price improves, many initial efficiency gains will be lost, as margins recover and the impact of company consolidations drive prices back up over time.
To continue to meet ongoing global energy needs, a step-change in subsea project economics is required. This is why proven and qualified new technology is important, as it offers an enduring source of cost reduction. m-pipe® offers a sustainable way to reduce CapEx and OpEx over the whole life of a project, from simpler design to faster deployment, lower maintenance and longer subsea life.
m-pipe weight and strength reduces both cost and risk
The weight of subsea pipe is a key factor in total subsea project costs, affecting subsea architecture, ancillary component design, buoyancy and crane requirements, manual and ROV handling and vessel size. At 20% of the density of equivalent rated Non Bonded Flexible (NBF) or steel pipe, m-pipe® dramatically reduces both the deployment spread and the facilities required for subsea deployments.
m-pipe® is also a proven subsea technology that is qualified to DNVGL-RP-F119. This recommended practice was developed through a DNV GL-led joint industry project involving 18 companies, including Magma and Operators like Shell, Statoil and Total as TCP end users.
m-pipe® end fittings interface with all standard oilfield connectors and m-pipe® has been used for water, hydrocarbons, gas, high sour, high temperature and high pressure service. Our TCP product is at TRL7 with Operators since 2012 in the North Sea.
m-pipe TCP is lower cost
At current oil prices, many subsea projects show negative project margins, a challenge for Operators around the globe. Magma has been able to build a TCP pipe that is higher performing than our competition, and yet lower cost foot per foot. This has been achieved by streamlining the supply chain with our partner Victrex, optimising the wall thickness of m-pipe® and removing key sources of wastage in our automated manufacturing process.
Multiple studies by Statoil, Subsea7, Chevron, Total and Petrobras have shown 30% to 45% total subsea project cost savings using Thermoplastic Composite Pipe (TCP) for both jumpers and flowlines. Compared to equally rated steel or Non Bonded Flexible (NBF) pipe, the light weight and strength of TCP is key, delivering this commercial advantage when pipe, fabrication, transportation and installation are all taken into account.
And, when flow rates and maintenance and replacement issues like sour service corrosion, hydrate build-up, erosion and hydrogen embrittlement are included, the whole-life project cost savings are even greater with m-pipe® TCP.
Lower cost design and deployment
The combination of m-pipe® spoolability, light weight, low product volume and fatigue resistance greatly simplifies deployment operations. This accelerates installation, reducing deployment costs and minimising fabrication requirements and ancillary subsea plant, as well as making manual, crane and ROV handling easier.
For intervention lines for example, fatigue resistance and pipe longevity remove lost time wasted on replacing and coiled tube. The light weight and high flow rate capability of m-pipe® speeds up hydraulic pumping and pipe retrieval and removes the need for additional buoyancy.
For subsea risers, the light weight and low product volume of m-pipe® means more product on existing carousels with less returns to the spool base. Light weight also means simplified riser architectures with less buoyancy and faster running times. In fact a recent detailed SLOR study showed a reduction in installation from 30 days to just 2 days by using m-pipe®.
For subsea jumpers, the flexibility of m-pipe® removes the need for pre fabrication metrology and simplifies rigid spools’ complex 3D shapes into a simple arch. This removes the time to fabricate the jumper from the critical path to first oil and also increases the number of jumpers a single vessel can install.
Improved subsea project returns
m-pipe® is a game-changing technology that enables an essential period of change in improving offshore project economics, simplifying subsea architectures, reducing subsea project risk, and reducing time to first oil.
The light weight of m-pipe® also enables faster and easier deployment, simpler ballast and buoyancy, and low-load rapid ROV connection.
Its fatigue resistance, high flow rate smooth bore and corrosion resistance all provide longer subsea project life, improving the ROI for new field developments and existing offshore sites, as well decreased time on well during hydraulic intervention operations.
The spoolability of m-pipe® also aids transit, loading and handling for tieback, infield flowline and light well intervention applications.
Lower subsea installation costs
Subsea infrastructure and deployment typically make up one third of a deep water project’s costs and, in deeper water, the riser installation makes up a significant portion of this.
m-pipe® is light, strong and flexible and these factors help deliver cost reduction across all subsea project applications. Recent detailed comparative studies with Operators and installation contractors show that m-pipe® not only reduces project Capex inflation risks, but enables far simpler architectures and reduced installation Opex.
For subsea jumpers the removal of a prefabrication metrology stage and the ability to hold completely standard, lightweight, product that is flexed to fit by a small vessel, reducing the cost of installation. For intervention, speed of deployment and recovery also drives significant cost reductions.
Deep water projects using existing steel and Non Bonded Flexible pipe need complex subsea architectures simply to support the self-weight of the risers, and need larger, more expensive construction vessels to install them.
The light weight and volume advantage of m-pipe® means reduced hook loads and tensioners, so smaller vessels with lower day rates can be utilised, completing installations faster and reducing the overall deployment cost.
