Incident Recommendations

• Pneumatic quick exhausts should be fitted to pressure pilots to assist in quickly depressurising the ESD loop.

• Each ESD system installation must be function tested in situ prior to use. The time taken for the ESD valve to close after activation from various points should be recorded. This process should be part of the pre flow commissioning of a well test package.
