Summary
During vessel maintenance, a hose disconnected while residual water was pumped from a cofferdam at approximately 5.9–6 bar. Nobody was struck or injured. The flash identifies absent whip arrestors, missed pre-use checks and an apparently worn coupling, and recommends secondary securing, coupling inspection and sufficient onboard spares.
