Incident Location

Fixed Installation

Incident Activity

Production operations

Specific Incident Equipment

Hedemora diesel engine.

Lessons Identified

• Design integrity of potential HCR leak sources should be assured
• Appropriate risk assessment of process and auxiliary equipment should be performed and documented
• Operational demands on standby equipment should be better managed to minimise failure potential
• All operationally-critical equipment should be subject to planned maintenance

Incident Recommendations

• Overhaul fuel pumps with complete new Woodward parts on all operational Hedemora generators
• Grub screws to be secured using high strength, high temperature “Loctite 278”
• Update maintenance records to ensure only new Woodward service kits are used on the fuel pumps.
• Implement planned maintenance routines to correctly overhaul the fuel pumps.
• Consider replacement of the Hedemora generators with more up to date engines
