Summary
A fire hose coupling failed during annual pressure and leak testing aboard a vessel. Examination identified corrosion and seized floating flanges, with advanced deterioration also found at the opposite end. The flash recommends targeted coupling inspections, detailed planned maintenance and personnel briefings; brass may be preferred when replacement fittings are required.
