Equipment LL with PGNiG
Tomcat (6501/10-1) – Surface section
What happened:
Set HAL suspension plug as pr HAL manual, plug depth +- 593 m. Pressure tested plug to 290 bar/10 min. Not able to disengage RT from plug. Called support and tried several times. Ended up releasing whole plug and POOH with same.
What was planned:
Disconnect from intercept plug
What was learned:
Low confidence in Interceptor plug. Poor quality on manual and instructions for running same. HAL rep (cementer) not trained in EQ. Documentation in Orlen/WE sharepoint poor.
What actions are required:
HAL to have better control of training of personnel for different EQ planned on well.
Supply documentation at an earlier stage and store at a suitable folder in Sharepoint in addition to HAL rep.
Prepare and update DOP.
