A North Sea Operator had planned to replace two 36” isolation valves offshore. The replacement of these valves within the utility shaft was an essential piece of maintenance that was required for continued safe operations.
The high-risk nature of the task meant safe isolation was required prior to replacing the valves. Salus Technical undertook an assessment to identify the risks associated with the safe isolation of the utility shaft. This assessment also assisted the Operator in making an informed decision on the isolation option which reduced risk to as low as reasonably practicable (ALARP).
The Challenge
The hazard identification (HAZID) study and ALARP assessment was carried out remotely, and hence required expert facilitation to ensure the all disciplines were engaged. Furthermore, the session required a chair, who had a practical understanding of the task at hand along with experience in identifying and assessing risk.
The Solution
We drew upon our operational experience and risk management expertise to swiftly identify the documentation and key individuals involved. We then spoke to key individuals to understand concerns and reviewed documentation prior to the HAZID, which ensured an effective session.
The Result
Using our expertise and experience in identifying hazards and assessing risk, we were able to provide the operator with a way forward that ensured risks were reduced to ALARP allowing them continue with business as usual.
