Thermoplastic Composite Pipe Technology
The Thermoplastic Composite Pipe (TCP) developed by Airborne Oil & Gas features a solid pipe wall, constructed from glass or carbon reinforcement fibres and thermoplastic polymeric materials. The unique, certified and proprietary manufacturing process results in a fully bonded composite pipe structure, with the fibres fully embedded within the polymer matrix and ensuring the strongest interface possible between the different pipe layers.
Our qualified design based approach builds on a fundamental understanding of the design, materials and production of our TCP products and of all load cases during deployment. This allows us to predict the product’s behaviour during all operational circumstances.
The benefits at a glance:
•No corrosion, excellent chemical resistance
•Light weight, reducing top tensions and transportation cost
•Long length per spool, reducing installation cost
•Smooth inner bore combined with high external pressure rating
•High internal pressure rating
•Flexibility
TCP Flowline
Costs associated with the prevention of metallic corrosion or replacement of affected subsea flowlines are a serious threat to profitable operation of new and existing assets.
With the introduction of our non-metallic, fully bonded TCP Flowline, corrosion is no longer an issue. This reduces the operational expenditure dramatically.
Our TCP Flowline is manufactured in long, spoolable lengths, reducing installation cost significantly, even comparing with carbon steel.
The TCP Flowline offers the following advantages:
•Fast and cost effective installation
•Lower total installed cost
•Long length, no or less end-fittings on the seabed
•No corrosion, lowest operating cost
•End-fittings termination on the platform, no overlength or spool requirements on the seabed
•Smooth bore – less wax deposition
The flowline is developed for offshore use in shallow and deep waters and is designed for oil field conditions with exposure to seawater, sweet and sour hydrocarbon mixtures and oil field chemicals.
TCP Spool & Static Jumper
Subsea spools and (semi) static jumpers are used as interface between flowlines, risers, manifolds and wellheads and need to absorb dynamic and static loads and displacements. Conventional steel spools are often complex 3D structures and come with a number of design, installation and operational challenges.
One of the most prominent issues and main cost driver is the metrology to establish the final jumper geometry. In addition the manufacturing time of a conventional steel spool is adding 3 – 4 weeks on average to the project critical path.
The TCP Spool and Static Jumper are our answer to these challenges; the TCP Spool and Static Jumper are flexible and can absorb significant installation tolerances, pipeline expansions and dynamic riser motions. Therefore accurate metrology and subsequent precisely manufacturing of the jumper is not required when using our jumpers and spools.
TCP Spool & Static Jumper advantages are:
•No metrology required
•Manufactured and terminated at required lengths, or in long lengths to be cut and terminated on site
•Significantly more tolerance in length than rigid pipe
•No complex geometry to weld and insulate
•No buoyancy required on most designs
•Reduce transport costs
•Can be coiled down on deck or on reels
•More pipe can be transported in a single mobilization
•Reduce installation costs
•Lower specification of vessel
•Multiple methods of deployment
•Direct over-boarding via VLS/HLS
•Conventional with less complex spreader bar
•Reduced barge / transport vessel costs, more jumpers per mobilization
TCP Riser
Deepwater risers connect wells on the seabed at water depths of sometimes more than 3000m, with the production facility floating at the surface. The challenges associated with the use of deepwater risers are large vessel payloads, complex riser layouts and associated high procurement and installation cost. Corrosion, fatigue and flow assurance further increase the design difficulties.
The TCP Riser is of lightweight construction; able to cope with high internal and external pressures and has a high strength to weight ratio. The latter is extremely beneficial in deepwater riser design, reducing tension loads in all types of riser configurations.
In particular, the TCP Riser allows for simple riser configurations that otherwise would not be possible. In the free hanging catenary configuration using TCP, the top tensions are low, well within the riser and end-fitting capacity and without added buoyancy. Compared to conventional free-hanging risers, a top tension reduction of more than 50% is achieved with the free-hanging TCP Riser.
TCP Riser advantages are:
•Low top tension
•Higher allowable topsides payload
•Simple configuration, less components, less interfaces
•Low installation cost
•No corrosion
•Excellent fatigue properties
•Inherent good U-value compared to steel risers, reducing the amount of insulation required
TCP Downline
Well stimulation leads to improved production efficiency at lower cost. Well intervention is proven to be the most cost effective method to maximise recovery ratios. Where subsea well intervention has been lagging behind, our TCP Downline and Jumper provide the fluid connection to the wellhead at lower cost per intervention.
The TCP Downline combines burst and collapse resistance with low weight, smooth bore and spoolability. This allows our clients to perform well intervention and well stimulation jobs faster, with higher flowrates, and pipeline pre-commissioning more efficient. The lightweight high strength TCP Downline can be deployed without using buoyancy elements. This results in considerable vessel time savings up to 24 hours per deployment.
The TCP Downline offers the following advantages:
•Highest internal and external pressure ratings
•High flowrate – smooth bore
•Fast deployment, reducing total time per operation
•Simple end-fittings that can be fitted within hours
TCP Jumper
The requirements for high pressure rating, maximum flexibility, high collapse resistance and high flowrate are the unique challenges that are set by our clients for dynamic jumpers used in deep water applications.
When pumping acids, or plugging a well, sub-hydrostatic pressures may occur. Having a collapse resistant jumper may prove essential to complete the operation without damage and delay.
Another industry requirement is the wish to replace conventional, small bore Flying Leads by products with a considerable longer design life.
For this purpose we developed the TCP Jumper, available from stock: a high collapse resistant flexible jumper with a smooth bore allowing operations in water depths exceeding 3000m, delivered within weeks.
The TCP Jumper has the following advantages:
•Highest collapse ratings in the market
•Smooth bore, enabling cement pumping and high flowrates
•Vacuum capability
•Tensile strength sufficient to disengage emergency quick disconnect
•Light and relative flexible, easy to handle in back deck operations as well as subsea by the ROV
