ON THE DEVELOPMENT OF DESIGN CRITERIA FOR COLLISION RESISTANCE
Long since considered as a means of preventing or reducing the consequences of vessel collisions, design criteria for improving the quality of ship design are increasingly being examined. This paper attempts to identify the design criteria for certain types of vessels by analyzing the mechanics of collision and its levels of risk. It is shown how the basic mechanics of collision is determined from the laws of conservation of energy and momentum, assuming that the collision is perfectly inelastic. Although elastic energy absorption was found insignificant in some types of collisions, a solution is derived for estimating the plastic energy absorbed in a minor collision. Factors affecting energy absorption in minor tanker collisions are then identified, and a probabilistic approach to the study of collisions is presented. After establishing the mathematical requirements for determining the design criteria, the author concludes with a discussion of the environmental, regulatory, statistical and economic aspects as they relate to these collision resistance criteria.
