Summary
An ROV manipulator fuse bolt ejected its head during pre-dive testing, narrowly missing a technician without injury. Investigation linked the failure to damage sustained during heavy work on the previous dive. The flash recommends manual jaw operation before energising hydraulics, directing arms away from people and assets, and controlling access during deck checks.
