A ship has reportedly lifted 31,000-ton oil platforms without using a crane, by sinking down to allow steel beams to slide under the load and then rising to lift the platform. However, some reports suggest that super heavy lift cranes may have been involved in solving engineering challenges, potentially contradicting the claim of no crane use. The operation is part of decommissioning efforts at an oil and gas field, with one outlet reporting that a final topside has been moved quayside.
