Summary
An undocumented gas-hose repair was discovered during demobilisation of a diver umbilical, which was subsequently scrapped. The heat-shrink-covered join could trap seawater and accelerate fitting corrosion, potentially interrupting breathing-gas supply. The member allowed such repairs only temporarily, pending a permanent fix, risk assessment and full management approval.
