. . . they were originally invented and designed almost 100 years ago for fresh water systems, and therefore are unable to cope with the marine by-products produced by a sea water delivery system. These by-products not only contribute significantly to expensive and repetitive service and maintenance regimes, but have resulted in a culture of “fail and fix” compliance test procedures. A “pass” will never be set at 100% on first time system activation and normal test criteria is set well below this figure and allows for repeat testing until a pass is recorded.
When an offshore fire safety system is activated it will fail on first time activation where delivery line contamination is present, due to the sprinkler nozzles blocking regardless of delivery line material: the sprinkler heads will then be removed, cleaned, re-instated and tested in this way until a pass is recorded.
. . . when the inevitable does happen, who will be held responsible? The product company for failing to note on their data sheets that their nozzles will block and fail when used in a specific environment? The service company who makes repeat money out of a fail fix process with these products? Or the operator who doesn’t change its fire safety design? If a solution is available to put an end to this senseless attitude towards offshore personnel safety, someone must take responsibility and ensure a culture shift before it’s too late . . .
