The strength-to-weight ratio and resistance to corrosion of carbon fiber subsea risers over steel are its primary advantages. A subsea riser made of carbon fiber is typically 20 times stronger than one made of steel for the same weight. In general, carbon fiber can be used to do anything steel can be.
Carbon fiber, on the other hand, enables a novel and more effective alternative to steel and flexible riser architectures that are not bonded.Although the polymers that make up the inner surface and matrix of a carbon fiber pipe are not all chemically resistant, any riser concept that is based on carbon fiber pipe has an inherent advantage in terms of resistance to corrosion.
PEEK is a particularly appealing polymer because it is unaffected by oil field chemicals, particularly carbon dioxide (CO2) and hydrogen sulfide (H2S), which pose particular challenges for steel structures. The pipe can also withstand high temperatures thanks to PEEK, and its extremely low permeation makes it ideal for gas applications.
The emergence of US shale and low oil prices have put pressure on the development of deepwater fields. The offshore industry has responded by looking for technologies that can cut costs and speed up the first oil extraction process for deepwater reserves, especially those in harsh environments.
As a result, there is now a growing interest in the use of thermoplastic composite pipe (carbon fiber) for risers, flowlines, and jumpers. Several designs are either currently being developed or are planned for use in the future. Materials technology will enable the designs of the next generation of risers, paving the way for the use of composites in subsea infrastructure in the future.
The Global carbon fiber subsea riser market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The brand-new thermoplastic composite pipe (TCP) carbon fiber subsea riser developed by JPT Nonmetallic can now be found in every oil and gas region in the world. It can operate at pressures of up to 12,500 psi and in water depths as low as 3000 m. The current focus is on developing and deploying TCP risers for harsh environments.
The thermoplastic composite pipe (TCP) technology, which has been tested in the field, can now be found worldwide in every oil and gas region. TCP lines can be used for full wellstream service (hydrocarbons), water injection, chemical injection, methanol injection, gas lift, and intervention.
They are qualified for use with flowlines, jumpers, and spools. TCP items can at present be introduced and work at tensions of up to 12,500 psi, and in water profundities as low as 3000 m.
The attention is presently on the turn of events and arrangement of TCP risers for outrageous conditions. Airborne Oil & Gas is collaborating with engineering company SMEROS Technologies to deliver the first qualified TCP risers in the deepwater region of Brazil following the launch of a qualification program with Subsea 7 to certify TCP for dynamic riser applications.
A major operator in the region is providing funding for the program, which aims to qualify the TCP riser for pre-salt and highly corrosive conditions. It is anticipated to save an estimated 30% on as-installed costs and to be 45% less expensive than a flexible pipe in a lazy wave configuration because it is the world’s first fully bonded, free-hanging composite riser.
