During line pipe load out operations, three high potential near miss incidents occurred involving quayside crane lifting operations. All of the incidents had the potential for fatal consequences from line of fire situations. Two of the incidents resulted from the line pipe being dropped from the quayside storage positions, and the third as a result of line pipe contact with the ship’s hold bulkhead which could have caused the pipe to drop.
In all of the incidents, site activities were being directly supervised and controlled by our member’s subcontracted line pipe supplier. The operations involved a chartered heavy lift vessel, subcontracted by the line pipe supplier, to undertake the pipe load out activities.
What went wrong? What were the causes?
Our member noted the following:
- There was no work instruction available to detail the task and process of securing and lifting pipe from the quayside into the hold of the vessel;
- There was no requirement within the line pipe supplier’s management system to verify that their subcontractors executing the pipe load out understood and were experienced in the task, nor to verify the training and competency of those subcontractors;
- The communication process between the banksman and crane operator was not clearly understood (there was no documented process);
- The crane operator found it hard to see the banksman during the lifting operation, yet continued the lifting operation;
- The pre-job briefing did not cover all of the tasks to be conducted;
- There was a lack of experienced supervision at all stages of the pipe load out activities;
- The quayside slewing crane used was not as suitable for the task as the gantry crane, which was not always available for use.
What lessons were learned?
- In evaluation of potential suppliers:
- a focus should be placed on the high-risk activities that bidders are proposing to subcontract out
- do not assume that suppliers are knowledgeable and experienced in all aspects of their contract.
