Successful TCP Flowline tests on erosion, fire resistance and impact

In order to demonstrate the suitability of Thermoplastic Composite Pipe for static riser applications, Airborne Oil & Gas successfully completed three tests specifically requested by a West African operator:

  • Erosion: Erosion tests on coupon level have demonstrated superior behaviour of the liner material used in the TCP Flowline compared to a steel grade used for pipeline applications (X65) for different flow velocities. The tests have been performed under aggressive conditions, with high velocities and high sand particle concentrations. With improving performance compared to steel at increasing flow velocities, the material loss on the liner was 2.5 times less than the material loss on the steel coupons, the liner clearly outperformed steel during these erosion tests and demonstrated the excellent erosion resistance capabilities of TCP.
  • Fire: Survivability of a 6” TCP Flowline subjected to jet fires was demonstrated by exposing the pipe, protected by Passive Fire Protection (PFP) to burners with an average flame temperature of 826°C for more than 30 minutes, while the pipe was kept at the design pressure. The pipe survived the test and the residual burst capacity after the fire resistance test was still a factor 3.8 higher than the design pressure and only 6% less than the burst capacity of a new pipe.
  • Impact / collision: Finally, vessel collision scenarios have been tested for a range of impact velocities on a 4” TCP Flowline. In one test a pipe was subjected to an impact mass of 1,000kg at 2.4m/s. Following impact, an internal pressure test was performed at design pressure, to successfully demonstrate residual strength. In another test, a pipe was hit 5 times with velocities increasing from 1m/s to 5m/s. After the test, this pipe was also subjected to an internal pressure test and after successfully maintaining the design pressure, the pressure was increased and eventually the pipe burst well above the acceptance limit.

"These test results prove the suitability of TCP for riser applications", says Henk de Boer, Chief Technology Officer with Airborne Oil & Gas. "TCP can now be considered for flowline applications including riser sections, whereby the riser section is clamped to the platform."

TCP Flowline

TCP Flowline eliminates corrosion and is the lowest total installed cost solution for greenfield and brownfield applications

Airborne Oil & Gas designs and manufactures TCP Flowline products for hydrocarbon production, water, gas lift, and chemicals injection. Its non-corrosiveness, light weight, spoolability and ability to terminate in the field make it the best solution for in-field flowlines, tiebacks, single well step-outs, and (quasi) static risers.

The solid pipe structure is impervious to corrosion, resulting in outstanding performance in corrosive environments. It has an inner, fully bonded, smooth bore polymer liner that ensures the best attainable flow properties while still being piggable. The thermal performance of TCP is considerably better than that of steel (reinforced) pipe. Our end-fittings are simple and robust, relying on a well-proven mechanical clamping method. Assembly of the pipe with our end-fittings is straightforward, can be done both onshore and offshore and at any location on the pipe.

TCP Free Hanging Risers

TCP Free Hanging Risers deliver significant cost reductions compared with the traditional Lazy wave Riser solutions used in deep water harsh condition areas such as Santos Basin Brazil

Airborne Oil & Gas designs and manufactures TCP Riser products for hydrocarbon production, water and gas injection, gas lift and chemicals injection. Its light weight, good fatigue performance, non-corrosiveness and spoolability make it the best solution for Deep Water Free Hanging Risers.

Our TCP Riser is supplied in long spoolable lengths for cost-effective reel lay and lowest as-installed cost. This leads to a radical 30% saving on as-installed cost as shown in the TCP Riser business case.
