5.0 Post Inspection discussion
I gave UMM Ivers a brief of observations from the inspection, I also stated my intention to review Statutory reports further for Floor Heave events and Gas trips resulting from these events.
The surface Statutory Notice Board in the Muster area was not up to date, there was an MRE absent, the V.O’s monthly report was more than 3 months old and the Safety Bulletins were not the most recent Bulletins issued. Mr Ivers gave an undertaking this would be addressed.
