81061 - Prediction of Inclined Surface Spreading Extent for High Flashpoint Fuel in Large Compartments Under Ship Motion 

Ships under operation are exposed to dangers such as accidental spillage of high flash point fuel. Spillage of ships are affected by ship motion, which may cause the pool area to increase. If the pool with the increased area is ignited, a large-scale pool fire could cause a significantly greater damage to human life, property, and environment. Especially, in cases where large compartments are required such as in Ro-Ro ships, the degree of damage could increase substantially. Therefore, effect of ship motion on the spread extent of a pool should be considered when conducting fire analysis on ships. However, a quantified formula for a spread area of high flash point fuel over an inclined surface does not exist. The objective of this paper is to propose an empirical formula that predicts the spreading extent of high flash point fuel in large. High flash point fuel discharge experiments were conducted on a steel plate to analyse the effect of substrate angle and discharge rate on the spread characteristics. The experiment results, along with a series of CFD simulations, were used to develop an empirical formula which predicts the spread extent of high flash point fuel on an inclined substrate. Applying the proposed formula, variation of fire characteristics under different conditions were investigated.
