What this video covers

The crew of SV Delos successfully flipped their 53-foot aluminum catamaran hull using a dual-crane operation after 14 weeks of upside-down construction.0:16 The vessel, estimated at 5.2 tons, required a 60-ton boom crane and a 20-ton FRANA wheeled crane to rotate the hull 180 degrees.5:25 Engineers calculated the center of gravity at 7.6 meters, with lifting points adjusted 1.25 meters to either side to ensure stability during the lift.9:03 The process involved moving the hull out of the shed with the FRANA, suspending it from a crossbeam, and using manual taglines to rotate the structure before lowering it onto supports.7:14 The team utilized 204 kilograms of aluminum welding wire during the fabrication phase to complete the hull.1:52 The operation concluded without incident, confirming the structural integrity of the fabricated lifting lugs and the accuracy of the weight calculations.18:58
