Container carriers are in general a safe ship type. Nevertheless, risk from some types of accidents can be reduced in a cost-efficient way. An example is fire and explosions, which contribute to about third of recorded fatalities onboard container ships and provide the second-largest contribution to the overall cost of accidents. Fire and explosions in the cargo area are especially difficult to handle, because both the fire detection and, especially for deck cargo fires, fire fighting are difficult. A series of full-scale fire tests on two loaded 20-ft sea containers was carried out in order to estimate cargo fire risks for container ships, assess the behaviour of unprotected steel construction in fire, and provide data for the validation of numerical methods. Gas temperatures in the containers, temperatures of the steel -and concentrations of gases were measured. The air supply was varied in the tests by partial by partial elimination of the bottom and opening the door in order to model a partial loss of integrity. The conditions varied from a closed container with a strongly under-ventilated fire to flashover with strong convective flames and high temperatures. In addition, numerical simulations were carried out in order to enhance the understanding of the phenomena.The results show that in none of the tests a destruction or some damage of the tested contalners occured,which can compromise container integrity or stacking safety.
