2H Offshore Awarded Production Riser Testing Program

2H Offshore has been contracted by Chevron to manage a production riser weld qualification testing program.

The aim of the development of 20,000 psi technology is to qualify the equipment required 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. 2H Offshore said this is beyond what the industry has already qualified and installed to date for fatigue sensitive deepwater risers.

The scope of the program will incorporate test pipe specifications, procurement and qualification of new welding and AUT procedures and comprehensive fatigue testing that will include the effects of sour service conditions. In addition, the project scope includes the development of feasible marine riser system configurations for a number of different host vessels.
