Summary
A vessel’s dive-control electronics lost power during ROV recovery on a shared power bus. Low supply voltage activated the UPS internal bypass, after which circuit breakers tripped. The dive was aborted without injury. Actions included keeping the bus tie breaker open, disabling internal bypass and introducing daily UPS health checks.
