Upgrade & Rebuild of Hurricane Damaged Rig

During Hurricane Katrina, the offshore construction and accommodation rig CSS Chemul became wedged under a bridge in Alabama while undergoing repair work at a nearby shipyard. Five years later, the CSS Chemul was transported to Halifax Shipyard, where Allswater’s engineering know-how played a key role in the upgrade and rebuild of the rig.

The rig required a comprehensive overhaul and rebuild, demanding innovative solutions and seamless collaboration among engineers, project managers, fabricators, and the shipyard. The challenge was heightened by the tight construction schedule and the stringent operational requirements set by PEMEX, Mexico’s state-owned petroleum company.

The first phase of the overhaul and rebuild was successfully completed by the shipyard, meeting all of PEMEX’s stringent standards. Impressed by the quality of work, Allswater was retained—alongside the shipyard—to complete additional upgrades on the rig. After more than six years of post-Katrina repair work, the CSS Chemul returned to operation, fully equipped and ready to meet the challenges ahead.
