This course has been developed to enhance diver safety when working near potential sources of stored energy, providing essential knowledge and awareness of surrounding subsea isolations.

Due to diving incidents regarding unplanned hydrocarbon releases, and potential injury to personnel during subsea intervention projects in the oil and gas industry, this course has been developed to enhance diver safety when working near potential sources of stored energy.

The course will provide all persons involved with diving and subsea operations, an awareness of the principles of subsea isolations from planning to completion, both from platform control room to the subsea work site.

Course objectives

This training course has been designed to provide candidates with the general principle of isolation, where the removal of hazards or sources of energy can be confirmed to provide adequate disconnection of that system, from any potential source of further energy.

This course has been developed to enhance diver safety when working near potential sources of stored energy, in response to diving incidents regarding unplanned hydrocarbon releases, and injury to personnel during subsea intervention projects in the oil and gas industry.

The course will provide all persons involved with diving and subsea operations, an awareness of the principles of subsea isolations from planning to completion, both from a platform control room to the subsea work site. The syllabus examines previous examples in the offshore environment and identifies potential work place hazards, teaching industry approved control measures including legislation and guidance.

Entry requirement

Candidates should be employed within the oil and gas industry and be familiar with the concept of isolations and potential for stored energy. Typical candidates would be diving supervisors, client reps, platform control room operators, subsea engineers, platform OIM, DSV OPM, client PM and anyone with a duty of care as per DWR 1997.

Certification

On completion of the course, each student is issued with an NHC certificate of competence.

Course duration

2 Days.
