Alert 06 – 35 Release of Pressure Results in Laceration and Sutures
WHAT HAPPENED:
While pressure testing the Choke Manifold up to 15,000psi the Assistant Driller noticed a leak at the test hose at approximately 9,000psi and asked the Motorman to repair the leak. First the Assistant Driller opened the bleed valve at the test pump and then he went directly to the Choke Manifold so that he could bleed off the volume in the line to the trip tank. While the Assistant Driller was still opening the valve the Motorman disconnected the quick release couplings at the choke causing the escape water pressure to lacerate the left palm at the base of the thumb. The laceration required four sutures.
