Alert 02 – 10 Casing Incident Results in LTI
WHAT HAPPENED:
Recently, a casing crew was running a string of 9 5/8” casing, with the assistance of a third party company’s Lay-down Unit. As a joint of casing being brought to the drill floor in the lay-down trough reached the V-door, the upper section of the lay-down pole suddenly sheared off. The laydown pole stands in the mouse hole and is used to anchor the fast line cable and lay-down trough with a cable and sheave attached to the top of the lay-down pole. The lay-down pole sheared at the point where the steel base plate, used to maintain proper working height, was attached to the pole.
