TCP Flowline for Water Injection service

Project description
Early 2019, Strohm was awarded with a contract from OCEANEERING for the supply of 4 km TCP Flowline for Angola. The field is located approximately 40 km offshore in water depths of 60 m. Under this contract, Strohm provided OCEANEERING with a 7.1” ID, 159 bar design pressure platform to platform TCP Flowline for Water Injection service. 

The TCP Flowline was delivered on two Strohm T&I reels and was installed from a small, multi-purpose vessel, with J-tube pull-through at both platforms. The TCP Flowline is non-corrosive, lightweight, flexible, spoolable with a small minimum bend radius and can be terminated at any location along the pipe. In this case it allows for fast topside end fitting termination after J-tube pull-through. This provides the end user with project value in lower total installed cost through cost effective transportation, smaller J-tubes, while de-risking the project schedule.

The TCP Flowline has a small CO2 footprint compared to steel and flexible pipe as a standalone product, and when considering the installation as well, the as-installed CO2 footprint reduces further to around 60% overall reduction. This way TCP enables the end-user to reduce the footprint in their operations.
