United Kingdom : 2H Offshore secures deal to handle Production Riser Testing
Publish Date : 06-Oct-2015
Chevron has awarded a deal to 2H Offshore, an Acteon company to manage a production riser weld qualification testing programme.
The objective of the improvement of 20,000 psi technology is to specify the equipment needed to develop future offshore fields with design pressures above 15,000 psi and temperatures above 250 F. These design pressure and temperature requirements result in line pipe wall thickness requirements as much as 1.9-in. for 8 to 10-in. diameter risers. This is beyond what the industry has already qualified and installed to date for fatigue sensitive deepwater risers.
The programmes scope would include test pipe specifications, procurement and qualification of new welding and AUT procedures and comprehensive fatigue testing, which would cover the effects of sour service conditions.
Additionally, the project scope covers the development of feasible marine riser system configurations for a number of different host vessels.
Nuri Saglar, 2H project manager, said, We will be pushing the boundaries of current pipe manufacturing and fabrication processes in the programme, and we look forward to supporting Chevron in developing a fit-for-purpose welded riser joint for the next generation of high pressure, high temperature (HPHT) field developments.
