USCG announced that the Outer Continental Shelf National Center of Expertise (OCSNCOE) published two reports on lessons learned from past events. One of the reports covers an inadvertent button-push and risk identification in the Job Safety Analysis.
A drillship had a recent near-miss while drilling an exploratory well in the Gulf of Mexico.The event provided several lessons learned for the vessels with dynamic positioning(DP). The vessel was conducting what seemed to be a simple maintenance procedure on a thruster.However,human errors with a mix of ergonomics got involved and resulted in a position loss within five feet of a “yellow” condition.The incident was caused due to the proximity buttons to one another as well as the number of alarms a DP operator (DPO) recieves.
Lessons Learned
- Do my work permits adequately identify the risks?
- Doew my well specific operating guideline take into account well control operations?
- Should certain controls on a DP system be protected from accidental activation?(a cover was later added in this case)
- Is there good communication between the drill floor and the bridge during simultaneus operations?
- When the bridge receives multiple alarms,is the DPO taking the extra second to recognize the alarm before the proper action?
