Strohm’s "Jumper on Demand" concept allows multiple pipe lengths to be spooled from a delivery reel of continuous pipe and cut into discrete jumper lengths on site.
Strohm has fabricated the first of 13 water alternating gas injection (WAG) thermoplastic composite pipe (TCP) jumpers for the Yellowtail development offshore Guyana, operated by ExxonMobil.
Under Strohm’s "jumper on demand" concept, multiple lengths can be spooled from a reel of pipe for cutting into discrete jumper lengths on site. The company’s field service team will then fabricate and terminate the individual jumpers.
Strohm claims this approach enables large volumes of jumpers to be manufactured faster.
Earlier this month, the first two TCP jumpers for Yellowtail were integrated with vertical connections, pressure tested and installed subsea in water depths of more than 1,700 m by means of a spreader bar. They were then locked in and back seal tested.

Tests and engineering assessments are said to have confirmed the pipe’s performance in real conditions and the ease of installation, using flexible pipe installation vessels in Petrobras’ fleet.
The TCP was tested using the same methodologies and standards as for conventional flexible pipes.
This is the first offshore trial for Petrobras to include TCPs.
