New DNV protocol promises HSE improvement

Det Norske Veritas’ ‘isrs7’ process safety management service addresses major accident risk.

A new ‘protocol’ from Det Norske Veritas (DNV) addresses what is described as ‘the continuing impact of major accident hazards’ in the oil and gas industry with a new process safety management (PSM) tool, ‘isrs7.’ The Baker and Chemical Safety Board reports on BP’s Texas City disaster confirm DNV’s experience that existing management safety systems did not perform well in the face of a major accident.


Graham Bennett, DNV Energy’s downstream business leader commented, ‘There is a need for a fresh approach to effective PSM. The new isrs7-PSM tracks the status of multiple layers of hazard management protection such as process plant condition, people issues, management effectiveness and business processes. In addition, it helps drive the improvement process.’


DNV’s International Safety Rating System (ISRS) is used to measure, improve and demonstrate safety, environmental and business performance. The new service takes a holistic view of the management of major accident hazards. DNV has already undertaken a number of PSM projects and plans to leverage these as a reference base for benchmarking PSM performance.
