Summary
An investigation examines a platform crane incident during toolbox transfer to a motor vessel. The load and boom dropped, and the toolbox was lost overboard after striking the water. Findings attribute hydraulic pressure loss to relief-valve failure and corrosion. The narrative and attachment give conflicting accounts of pre-use inspection.
