On October 14th, 2020 at 14:00hrs, the DWS HDU-1 crew were laying down water hoses in Thamood. During the last 100m of hoses remaining to being laid down, the crew decided to proceed directly from the trailer. The reels on the trailer were unsecured. The rigger who was standing in between the stack of moving reels at the front left of the trailer, instructed the trailer driver to stop. The sudden harsh braking by the driver after the rigger’s instruction, caused the unsecured rotating reels to come out of their connections and strike the rigger on the right side of his face, resulting in his head injury. The rigger was immediately transported to RIG 38 for first aid and then transferred to Shaleem Hospital, then onwards to Salalah Sultan hospital for further treatment.
