Industrial Safety Incident Analysis

Incident Reports Overview

• Nitrogen Tank Incident: An unplanned energy release caused a nitrogen vessel to strike a worker, leading to injuries from falling and hitting his head.
• Medivac Response: The injured person was transported back to the vessel for immediate medivac service to a hospital.

Investigation Findings of Nitrogen Tank Incident

• Weld Issue: The skid remained welded to the deck, known only during preparations.
• Insufficient Preparation: The decommissioning project suffered from rushed planning, impacting resource availability.
• Lack of Control Measures: No Control of Work or Management of Change protocols implemented prior to the second lift attempt.
• Ignored Feedback: Crew member objections before the lift were not addressed.

Lessons Learned from Nitrogen Tank Incident

• Resource Allocation: Ensure adequate time and resources for project preparation.
• Rigorous Processes: Apply Control of Work and Management of Change to identify unknown hazards and mitigate risks.
• Effective Communication: Listen to raised concerns and discontinue operation if protocols fail to conform to established plans.

Moonpool Incident

• Fall Arrest Incident: A third-party worker was pulled to the deck by a swinging whip line while operating near the moonpool.
• Lack of Communication: Inadequate instructions created a hazardous setting; no clear signals to stay clear during operations.
• Situational Awareness: The worker failed to recognize the dangers of their location.

Root Causes of Moonpool Incident

• Planning Deficiencies: Inadequate preparations led to the incident.
• Supervision Problems: Weak oversight allowed for unsafe work practices.
• Behavior Reinforcement: Lack of emphasis on proper safety behavior contributed to the accident.

Preventive Measures for Moonpool Incident

• Improved Communication: Strengthen interaction between deck crews and contractors to enhance safety.
• Usage of Taglines: Utilize taglines in congested areas to maintain control over swinging lines.
• Awareness of Surroundings: Encourage workers to remain clear of operations using moving equipment.

Seawater Inlet Pipe Leakage

• Leak Discovery: Seawater ingress was found during routine maintenance offshore; corroded piping was identified next to the hull.
• Lack of Condition Checks: No documented checks for sea-side valves and associated piping in vessel maintenance protocols.
• Deterioration Risks: The pipe’s corroded state posed significant risks of increased leakage.

Corrective Actions for Pipe Leakage

• Emergency Response: A cement box was quickly constructed to contain the leak.
• Dry Dock Repair: The vessel entered emergency dry dock for permanent repairs afterward.

Recommendations for Maintenance

• Regular Inspections: Implement routine checks for seawater valves and piping as part of standard maintenance.
• Pre-Dry Dock Assessments: Conduct thorough inspections before dry docking to ensure the integrity of critical systems.

Security Incident - Illegal Boarding

• Armed Intruder: An intruder with a knife boarded a vessel while anchored, discovered during a security patrol.
• Vulnerability Factors: Vessel design and location made it prone to unauthorized boarding incidents.

Contributing Factors to Security Incident

• Local Threat Environment: Increased incidents of theft at the Luanda outer anchorage area noted.
• Pre-incident Discussions: Vessel team had discussed threats but failed to enhance security measures prior to anchoring.
• Access Points: Intruders reportedly accessed the vessel via fenders or rescue boat areas.

Security Enhancements Suggested

• Thorough Briefings: Conduct detailed security analyses prior to anchoring in risk-prone areas.
• Coordination with Authorities: Engage with port control and nearby vessels for collective security measures and incident reporting.

This quiz examines a serious industrial safety incident involving the release of energy from a nitrogen vessel tank. Participants will analyze the sequence of events that led to an injury and the response measures taken, such as the medivac transportation. Understanding these incidents is crucial for improving safety protocols in industrial environments.
