Sour service pipe test JIP begins at DNV GL

Offshore staff

SINGAPORE – DNV GL has launched a joint industry project to develop a way to evaluate fractures and cracks using a Single Edge Notched Tensile (SENT) test designed specifically for sour service environments.

“The JIP will involve detailed experiments and analysis to provide a better understanding of the key parameters known to impact fracture toughness test results,” said Dr. Jens Petter Tronskar, DNV GL vice president and CTO of the Deepwater Technology Centre in Singapore. “This will enable the development of a guideline which may further develop into a Recommended Practice which will provide significant technical, logistical and financial savings to the industry.”

The JIP is a joint effort between DNV GL Singapore Deepwater Technology Centre and DNV GL’s laboratories in Singapore and Columbus, and will be run in three phases over two years.

Eight participants are on board and the JIP is still open for new participants.
