FRC Crew Change Incident

NE Greenland

Sept 2009


Background

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.


Sequence of events

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.


Immediate actions taken

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.


Root causes

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.


Lessons learned

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
