- Abstract
- A study of fire risks in ships engine rooms shows that the main risk for fire is connected with leakage of petroleum products. Such a leakage could cause a spray fire, which if it is allowed to develope means severe damage in a short period of time. Extinguishing a spray fire could mean a considerable risk for the fire fighter. It is therefore quite motivated to have a good protection against such fires, primarily from health aspects, but also for economical reasons. Todays extinguishing systems of total flooding type in ship engines are too slow to respond to a spray fire, in order to reduce the damage approximately. They must be completed by a local extinguishing system, fast enough to knock down the fire in its very beginning. This report comprises an investigation of the fire risks, describes the setup of some experiments and briefly presents the test results. The report also gives suggestions for the design of a suitable extinguishing system. The system consist of fast detectors and a water sprinkler rig, for protection of engines running on heavy fuel oils. For engines fueled with marine diesel it is necessary to add foam as extinguishing media. A full presentation of test data is given in a separate report, "Extinguishment of Oil Spray Fires With Water--Experimental Procedures and Test Data", SP Report 1990:32.
