After World War II, the world economy gradually went to integration. With international trade growth, the rapid development of maritime transport has become the most important means in economic development and trade. The world wars of the 20th century promoted the rapid development of technology, which is brought about by a huge move to marine transportation. The most dramatic changes are with ships, such as the diversity of the ship. the ships’ design and manufacturing being upsized and capable and high-speed, as well as the communication technology and safety equipment of the ship.The seaport development is basic on the shipping raise. In the beginning, ports serviced to shipping docks, Marine cargo handling, storage and transport, et cetera. Nowadays, except for those basic functions, according to the requirement of modern logistics, the customers are regarded as the center, which involves perfect management and the controlling of the logistics services. For example, applying the information systems and other networks to improve the effectiveness to request the consumer demand.Just like the way peoples’ lives have changed, there are some important innovations in the ships and ocean transportation that have been made since the 1950s. The purpose of this research is to pay attention to the impact of technology in maritime transport and port management since World War II.Chapter 2 explores the academic literature about the fast development of ships and seaports after World War II and, at the same time, the changing or upgrading of technology in ships and seaports. In this part of the paper, it will also show some of the reasons why Singapore’s port has become the success that it is.Chapter 3 is about the same common method in research, which is what the writer has used. In this part, the pros and cons of this method, such asprimary research and secondary research, are clearly illustrated.
