Summary
A gas-bank equalisation transfer in an ashore yard suffered a cracked, incorrectly specified low-pressure fitting failure. A fragment struck a nearby workshop wall, and inadequate whip checks allowed hose damage. No injuries occurred. Lessons address pressure ratings, thread awareness, training, risk assessment, hose restraint, restricted access and real-time pressure measurement.
