On 01st May 2022, two pipe sections were bolted together for PE pulling activity. The bolting was done to arrest the anticipated movements on host pipe during PE pulling. When PE pulling was completed, both lines were in tension to one another. In order to arrest lateral movement of the host pipe, rigger attached the host pipe to a 07 ton HIAB by using web slings. After this, the rigger approached the other pipe section to remove the bolt. Rigger observed that tension is still there on the pipeline and the bolt was not coming manually. He decided to remove the bolt by hammering it. For removing the bolt, he positioned himself parallelly with the line and hammered it. As soon as the bolt detached from pipeline, the line made an abrupt movement towards the rigger. Seeing this movement, rigger tried to move back, but his right leg made contact with the pipeline, injuring him. The rigger then shifted to Tawoos PAC Clinic and subsequently to SQH Salalah for further medical management.
