  1. FRC Crew Change Incident NE Greenland Sept 2009

  2. Background Project Details: • Crew was operating on a project in NE Greenland where helicopter crew changes were not an option. • A vessel was contracted for resupply and crew change.

  3. Sequence of Events Location: Offshore NE Greenland Time of Event: 19:40 Local Time Sea Conditions: <1m swell • Seismic vessel transited into open water to facilitate the crew change between her and the resupply vessel. • The first transfer of personnel was performed with no problems or issues. • However, during the second transfer between the two vessels the FRC stalled and the engine could not be immediately restarted.

  4. Immediate Actions Taken • The resupply vessel and chase boat were immediately contacted to render aid and ready their FRC’s for immediate deployment. • The resupply vessel was able to maneuver close to the FRC providing a lee and enabling the FRC to be secured alongside.

  5. Root Causes • A residual of non-Arctic grade fuel was found to be in the fuel tank - which began to congeal in the sub-zero temperatures. • The congealed fuel clogged the fuel filter, limiting fuel flow to the engine - causing it to stall. • Lack of Management Control • Procedures not documented for preparing the FRC and Work Boat for Arctic Operations. • Management of Change not documented for small boat use variance from normal operating environments to arctic environment.

  6. Lessons Learned • Update of small boat arctic procedures to include: • Fuel tanks must be completely drained prior to any work in the arctic and replaced with proper arctic grade fuel • Safety Alert on the incident distributed amongst Business Unit • Reinforcement of Management of Change Procedures • A more comprehensive selection of tools onboard the FRC were made available
