The threat of large-scale pollution by tankers offers an incentive to increase our present knowledge in vessel groundings. The lack of research and technical writing as to the effects of waves on a vessel aground is emphasized. A procedure is developed to evaluate the likelihood of exceeding longitudinal strength of stranded tankers in waves. A software modification to Ship Hull characteristics Program (SHCP), a highly used naval architecture program, is described. The modification allows modeling of ground reaction for hull strength calculations of stranded vessels. An analytical technique for predicting hull failure based on the probability of wave height exceedance is presented. Computer runs using the hull form of a coastal tanker are evaluated. Pertinent environmental parameters acting on grounded vessels are defined. New salvage data collection procedures and equipment are proposed. The need to apply current microcomputer technology to salvage is addressed, and proposed hardware and software systems are included. Based on the work presented, sound initial salvage decisions, which increase hull survivability and decrease the chances of pollution, can be made. It is proposed that new technologies can augment a salvor's feel for the dynamics involved in salvage engineering.
