Equipment will be used for gas injection at Lapa pre-salt field
Dutch-based pipe manufacturer Strohm has signed a contract with French supermajor TotalEnergies to provide its thermoplastic composite pipe (TCP) solution for the Lapa pre-salt field in the prolific Santos basin offshore Brazil.
TCP can be used for a wide spectrum of applications such as supporting mature developments or for deepwater operations with high carbon dioxide contents that are typical of Brazil pre-salt projects.
Due for deployment in 2026, the TCP solution has been selected for the first time for flowlines to be installed at water depths of about 2200 metres. Financial terms were not disclosed.
With a design life of 30 years, the technology is immune to the phenomenon known as stress-induced corrosion cracking from supercritical carbon dioxide (SCC-CO2).
“It will be the first project like this in the pre-salt and we have carefully selected this innovative technology for replacing the flexible lines in operation with a clear focus on design life, performance and carbon footprint,” said TotalEnergies project manager Thomas Leize.
“This technology is important because it represents a solution to a long-lasting corrosion problem, at a competitive cost, applicable for ultra deepwater, in line with our commitment of reducing emissions from our operations.”
With an inner diameter of six inches and a 600-bar design pressure, the TCP flowline will be used for gas injection. It will be installed using a standard pipelaying support vessel.
TotalEnergies has recently installed a TCP jumper at the Egina field offshore Nigeria, and is now prepared to install a TCP flowline at Lapa.
