DNV GL, ExproSoft to develop risk-based subsea barrier valve test procedure
DNV GL and ExproSoft are joining to offer a risk-based approach to testing barrier valves in subsea completed wells anywhere in the world.
DNV GL and ExproSoft plan to develop the risk-based approach which will identify failure modes and causes, failure rates, analyze the consequences, establish a risk picture, and translate the results into a recommended test frequency. Further, a method to develop risk-based leak acceptance criteria may also be an outcome of this work. The results can be applied globally and are scheduled to be available in 1Q 2016.
“Changing today’s prescriptive test intervals and leak criteria to a risk and reliability-based approach, will achieve substantial year-on-year cost savings for operators in Norway and elsewhere,” said Kjell Eriksson, regional manager - Norway,DNV GL - Oil & Gas.
