What riser configuration is best for TCP?
The integrated weight coating offers the possibility to tune the mass of the TCP to the requirements from the global configuration analysis. By integrating weight into the TCP only where required, Airborne Oil & Gas can always offer the TCP in the configuration as preferred by the operator. This includes the free hanging riser configuration, enabling maximum flexibility in well placement, or other configurations such as tensioned configurations (for example steep wave configurations, top tensioned risers or riser towers).
What is an integrated weight coating?
The integrated weight coating is an optional fourth layer of the TCP. The materials used for this layer are the base polymer of the TCP (being PE, PA12 or PVDF) mixed with heavy particles. Like all other layers in TCP, also the weight coating is fully bonded to the outer coating layer.
For flowlines, on bottom stability is key. How is TCP made stable on the seabed?
Airborne Oil & Gas has developed a suite of solutions that allow the operator or the installation contractor to choose the best method. These include:
We work with the installation contractor and operator to select the best method and provide oversight during installation offshore.
How can the TCP riser be installed?
We have designed the TCP Riser such that today’s installation vessels can be used for their installation. We have been able to achieve this by selecting the right material in combination with optimised pipe design. Using current installation vessels, allows operators to replace the flexible pipe by TCP Riser, without the need to change their configuration or proven installation methods.
How is TCP Flowline and Jumper spool deployed and installed?
Airborne Oil & Gas designs TCP such that existing and known installation method can be used, albeit the most cost effective ones. This is summarized as follows:

How has Airborne Oil & Gas qualified TCP for SURF and Subsea Well Intervention applications?
Airborne Oil & Gashas qualified TCP in compliance with the recommended practice DNVGL-RP F119 for TCP in subsea applications. This qualification includes product qualification, materials, design approach and production. To date, we have qualified TCP for permanent application in Flowlines and Jumper spools for hydrocarbon service, methanol injection, chemical injection and water injection. For subsea well intervention applications such as Downlines and dynamic Jumpers, Airborne Oil & Gas is fully qualified for pressure ratings up to 10,000 psi. In 2018, design pressures up to 15,000 psi will be qualified as well.
How is TCP designed, how can I review the design and become acquainted with the methods?
Airborne Oil & Gas designs the TCP based on fundamental understanding of the behaviour of the constituents, the fibre and the polymer. In order to work with our clients on designing, we wrote a white paper on this subject, called Design and Qualification of Thermoplastic Composite Pipe. Please contact us to receive a copy of this document. It outlines the design and qualification method that we use. Further, in order to help our clients become more comfortable with TCP and its design, we do Lunch & Learns and we provide training on TCP design. Please contact us for more information: firstname.lastname@example.org.
How can Thermoplastic Composite Pipe reduce total installed costs and total cost of ownership?
TCP is lightweight, spoolable, flexible and does not corrode. These elements always lead to a significant reduction in total installed cost and total cost of ownership, through any one or a combination of the following effects:
We have proven business cases in working on our projects with our clients. We are happy to work with you on assessing the cost for your project too. Beyond the lower installation cost, the lifecycle cost is reduced because of the total lack of corrosion, and easy recovery of the flexible TCP.
What additional benefits does TCP bring, for instance for jumpers or risers?
The benefits of lightweight, flexible TCP offer huge knock-on effects that trigger clients to think further and use TCP to optimise the full field layout:
What are the main direct benefits of TCP for applications in SURF and Subsea Well Intervention?
The main benefits of using TCP differ for each application:
What are the advantages of TCP over steel pipes?
TCP does not corrode and reduces installation cost compared to steel pipes. The benefits can be summarized as follows:
How does TCP compare to RTP, or Reinforced Thermoplastic Pipe?
By nature of the TCP being stronger and truly fully bonded, the application scope of TCP is significantly larger than that of RTP. In short:
Is TCP eroded by produced sand or other forms of erosion?
Airborne Oil & Gas has completed an extensive erosion test program that showed that erosion performance is better than in steel. This test program included the creation and validation of a computational fluid dynamics model which allows us to perform accurate assessment of our clients erosion profile.
Is TCP damaged by impact of foreign objects?
Airborne Oil & Gas has conducted severe impact testing to understand the effect of impact loading on TCP due to dropped objects or very rough pipe handling. The test results have proven that the ductile and flexible materials that we use in TCP provide excellent impact resistance and shock absorption.
How is the TCP terminated, and can this be done in the field?
Yes, our TCP can be terminated in the field. Because of our strong and fully bonded wall, which includes the bonded outer coating, we can simply cut the pipe at any location along the pipe and terminate in the field. We can do this offshore as well, in horizontal or vertical position, for instance above the J-tube. This concept allows clients to have a length of pipe on stock and cut to the required length, an ideal solution in for instance subsea jumper applications.
Why does Airborne Oil & Gas use a coating on the TCP?
We apply a fully bonded outer coating for protection of the pipe during handling and installation. The outer coating is an integral part of the TCP as we use the same polymer as the matrix in the composite layer; as result the outer coating is very strong, durable and continues into the end-fitting as part of the termination. Our TCP does not suffer from rapid gas decompression, blistering or coating blow-off, which is a known failure mode on composite pipe systems with unbonded coating in gas service.
What materials does Airborne Oil & Gas use in TCP, and why?
We always select the most cost-effective material for each application. As with steel, operators do not use duplex stainless steel throughout their infrastructure; instead, they use the most cost-effective material where possible. In closely scrutinising all materials and their performance, today we have selected glass-PE, carbon-PA12 and carbon-PVDF as the best materials, for the following reasons:
1. These materials are most cost effective within their range of applicability of pressure and temperature.
2. They are the most flexible polymers leading to easy manipulation and installation. In addition, their ductility avoids any microcracking in the pipe structure during bending, as more brittle polymers are.
3. They allow for the smallest minimum bend radius, including risers, allowing for known and proven installation methods to be used.
4. All these polymers have already a long track record in Oil and Gas.
We are always happy to explain how we work in designing and selecting the right material and are happy to share cost comparisons with you. Please contact us for more information: email@example.com.
What is the structure and build-up of the Thermoplastic Composite Pipe?
The Thermoplastic Composite Pipe, or TCP, has one simple, fully bonded or monolithic pipe wall. It consists of an inner polymer liner, a composite reinforcement layer consisting of several individual plies of fibre reinforced tape, and a robust outer coating. The polymers used in the liner, fibre matrix and coating are always of the same type. We use PolyEthylene (PE), PolyAmide (PA12), and polyvinylidene difluoride (PVDF) as polymers, and glass or carbon fibres as reinforcement. All individual layers are melt-fused together, ensuring a bond between the layers that is as strong and durable as the base materials. The simplicity of the concept results in a safe and reliable product due to the very limited number of potential failure modes; the fact that we always use the most optimal material depending on the application ensures that we always offer the most cost effective solution.
Who is Airborne Oil & Gas and why does it claim to be the first and leading manufacturer of TCP?
Airborne International, as former parent company of Airborne Oil & Gas, developed the concept of TCP in 1999. Airborne Oil & Gas was set up as dedicated Business Unit under Airborne International to commercialize and further develop TCP. As such, Airborne Oil & Gas was the first company to have developed TCP in the world. Airborne Oil & Gas became an independent company in 2014. Today, we have the largest track record with most pipes in operation, including hydrocarbon service, and several records including the world`s deepest TCP in 2140 meters water depth, and the world`s first TCP Flowline for hydrocarbon service.
