Global Energy Ventures Ltd (ASX:GEV) has completed the second of the three cycle fatigue tests required to obtain an American Bureau of Shipping (ABS) full class design.

The testing is part of the company’s work in designing a new CNG Optimum ship to transport compressed natural gas (CNG).

The third and final test, which will involve cooled burst testing, has begun and its completion will meet ABS requirements to issue full design approvals.

ABS approval work remains within the original budget and will be completed this quarter.

GEV chairman & CEO Maurice Brand said: “GEV has one final test to complete and we are confident that it will be successfully completed in December.

“The GEV Canada team continue to work closely with ABS as we move closer to finalising all documentation to complete the process to obtain full class design approval for the CNG Optimum design.”

A second cycle fatigue test, referred to as notched burst test after fatigue, requiring fatiguing a specimen through three-times its design life, or 6,000 cycles.

The pipe was then burst with machined notches embedded to prove the pipe's ductility and ability to maintain burst capacity even with some initial defects.

Burst occurred at 7,571 psi which is more than double the maximum operating pressure, and as such was a ductile failure – this is a positive result and meets ABS requirements.

Cooled burst test after fatigue is the final remaining test and also requires fatiguing the specimen through three-times its design life.

The pipe is burst after it has been cooled to simulate temperatures that would result from the Joule-Thompson cooling effect of gas escaping through a crack.

This test has begun and will take about 14 days to complete.
