Near-miss: security of equipment
A member has reported an incident in which an ROV launch and recovery system (LARS) arrived offshore with parts missing. The LARS arrived onboard the vessel without the pin connecting the left side (standing on the LARS looking outboard) transport post to the A-frame.
Following investigation, it was learnt that the A-Frame lift post pin was in place when the new LARS system left the supplier, but was not in place when it arrived at our member’s storage facility. The missing pin was identified during ‘routine’ inspection after the unit had been lifted and transported (twice), lifted and installed aboard the vessel. For the pin to have been lost during transportation represents a high potential near miss for any vehicle (and passengers) who could have been struck by the pin falling from the moving transport vehicle.
Our member, in co-operation with the supplier, took immediate steps to ensure prevention of future incidents. Additionally, our member is in the process of designing a lift post pin that will include a retaining pin. In the meantime, Members are encouraged to conduct a careful inspection of all A-Frame lift post pins and verify that they are secure before equipment is lifted and transported.
