Study Notes
Incident Summary: Diving Operations and Equipment Failures
- A frozen water bottle's handle broke, falling on a diver below in the transfer lock.
- Increased bell temperature stemmed from shallow water diving and insulation, prompting use of frozen bottles to cool the interior.
- Key lessons involved awareness of procedure deviation, lack of risk assessment, and implementation of a "Hazard Hunt" for routine tasks.
- Plans initiated for equipping the diving bell with a chiller and revising the Management of Change process focused on safety measures regarding frozen bottle handling.
Issue with Taut Wire Recovery
- Divers were unexpectedly lifted 18m off the seabed due to a taut wire operation, risking pressure injuries and entanglement.
- Miscommunication arose as the open communication system was silenced, delaying bridge team response and assuming Dive Supervisor was informed without confirmation.
- Actions taken included issuing notices for proper umbilical management and establishing communication protocols to ensure clarity in divers' safety.
Hoist Equipment Malfunction
- A defective "pay-out" button on the electric winch led to continuous payout command, resulting in motor failure.
- The operator misunderstood the condition of the hoist equipment after repeated operations.
- Implemented actions included ensuring crew familiarity with OEM manuals, conducting regular equipment function tests, and reviewing maintenance practices to mitigate breakdowns.
Workboat Collision Incident
- A workboat collided with a wind turbine platform, injuring a crew member during routine maintenance transfers.
- The master lost situational awareness due to engrossment in paperwork, leading to a course deviation and the collision.
- Minimal damage occurred to the workboat, but the crew member sustained two broken ribs, prompting emergency medical treatment.
General Safety Recommendations
- Emphasize the importance of adherence to established procedures and thorough risk assessments prior to operational changes.
- Enhance communication protocols to avoid miscommunication and misunderstandings within diving and marine operations.
- Regular maintenance and functionality checks on equipment to ensure safety in high-risk operational environments.
