The training requirements associated with equipment and systems utilized in underwater salvage operations and with the diving activities which are a part of underwater salvage operations are examined. The major emphasis of the study was on the training conditions suitable for the diver. It was found that divers are best trained in a tank or in open water. The secondary focus of the study was on the operators of the man/machine underwater systems. The best training procedure for these men was found to be the use of an appropriate simulator. The third major category of persons involved in salvage operations is the topside crew. These men are faced with a problem-solving operation and their training may best be conducted by means of a model, an on-line computer, and scenarios depicting salvage situations. (JY)
