The work in a merchant ship can be divided into three main areas — deck, engine and service. These do not stand separate as watertight compartments. Consequent on the increasing application of electronics and computers, there are changing norms in the division of work among the three departments. In many instances there has to be co-operative effort and teamwork, since there are areas of overlap in functions. Studies in the growth of merchant navy services indicate great prospects for those who get trained in this area. Right aptitude is essential for success.
