Strohm has been awarded a contract from TotalEnergies to supply TCP flowlines for installation in Lapa NE field, offshore Brazil, at a water depth of approximately 2200 m. TCP is intended to replace existing conventional flexible pipes that are subject to CO2 induced stress corrosion cracking (SCC-CO2), a phenomena that is typical of the Brazilian pre-salt cluster, which leads to premature failure of conventional flexibles.
Recognising the limitations of traditional solutions, TotalEnergies identified Strohm’s Thermoplastic Composite Pipe (TCP) technology as a robust alternative to address SCC-related failures. TCP is immune to corrosion and is qualified for a 30-year design life under the same demanding operating conditions that affect conventional flexible pipes.
In 2025, Strohm delivered the TCP flowline system for this project, providing a reliable and long-term replacement solution. The TCP flowline significantly reduces maintenance requirements and lifecycle costs while ensuring operational integrity in ultra-deepwater environments.
Installation of the TCP system is planned for 2026.
