INCIDENT While preparing to install an Epoxy Grout Sleeve on 16” LEK – YIB GGP Gas Pipeline,

1. INCIDENT While preparing to install an Epoxy Grout Sleeve on 16” LEK – YIB GGP Gas Pipeline, two civil crew helpers were engaged in manually removing fallen soil in the pit in order to expose the line. A JCB was deployed so the bucket could be used to assist in removing soil from the pit (3 m depth). After completion of one side soil removal, the plant operator was instructed to shift the JCB to the other side of the pit and to excavate the remaining soil. In the process of removing soil from the bottom of the pit , the teeth of the JCB bucket struck and damaged a nearby 16”  GRE oil line. The affected 16” GRE header was isolated and the flow was diverted to alternative lines. Approximately 1m3 of oil and 2 m3 of water was released to the surrounding environment. The total deferment is in the order of 51m3. ROOT CAUSES: Use of JCB for soil removal in close vicinity of live pipe line without proper controls in place Lateral Learning Safe work execution shall start from planning stage all the way till completion People should be aware about consequences of breaking LSR’s. Recommended Actions: Discuss this alert in toolbox talks and HSE meetings and Distribute to all contractors Post on HSE notice boards Include in site HSE induction • Key Learning: • Where practically possible, avoid high critical activities during holidays. • All activities regardless how small they are, shall be included in PTW system. • Ensure strict adherence to procedures when working around live pipelines especially in congested areas. • Re-assess risks more frequently whenever there is a change in scope.
