Remarks: The crane operator picked up the equipment basket and swung the load around to be in position to load the basket onto an approaching M/V. The operator then swung the load back to load additional items. In doing so, he felt the clutch slip and he started to lose control of the load. He pushed the block and winch line levers down to stop the boom’s descent; however,  the boom did not stop descending until the load hit the water. The boom impacted platform railings, grating, and associated support structures and sustained substantial damage. The load remained attached to the crane boom.
