Safety Issue

The Job Hazard Analysis (JHA) for disconnecting from the CALM buoy did not provide an accurate assessment of the all of the hazards and associated risks in performing the task. In addition, the crew did not use it to assess the risks associated with undertaking an unfamiliar operation and it was reviewed without any involvement from the crew. Consequently, the JHA was not an effective means for assessing and controlling the risks associated with the operation of disconnecting from the CALM buoy.
