Incident Consequence
Hydrocarbon release

Incident Location

Fixed Installation

Incident Activity

Production operations

Specific Incident Equipment

Swagelok fitting on fuel gas system

Lessons Identified

The HVAC system to the enclosure was also investigated and found not to be functioning 100% correctly

It is suspected that this may have contributed to the build-up of gas in the enclosure if a weep were present. It was decided that it was safe to start up the gas turbine and, using an operational risk assessment (ORA), monitor the enclosure for fuel-gas leaks for the following two weeks.

Incident Recommendations

Complete ORA to allow operation of the turbine while monitoring enclosure and fuel gas cabinet for hydrocarbon levels. ORA to run for two weeks from start-up.
