Steel Crankshaft Case News

Removing a 132 metric ton engine from an 11 deck luxury cruise liner whilst it’s in-service may sound impossible, but that’s exactly what marine engineers Atlantic Pacific Marine (APM) did in February. The company teamed up with wire sawing experts Drillcut (UK) Ltd. to cut one of Disney Wonder’s Sulzer ZA40S engines into 32 separate sections en-voyage. The sections were then lifted out and off loaded, enabling ultra-fast engine replacement once the liner had dry docked in the Grand Bahama Shipyard. In all, the innovative process saved six dry docked days.
