Abstract
Tankers, bulk carriers and container ships are the three largest groups of ships in the global commercial fleet. This shows that the design and construction of these types of ships deserve special attention. The IEA said global oil demand data indicated the market was approaching a rebalancing of supply and demand. Even so, this rebalancing prospect is still uncertain because there is little evidence that oil inventories are falling as expected. Thus, the development of oil tanker fleet of the world in general and of Vietnam in particular is an inevitable and objective trend. The development and design of new models takes a lot of time, effort and money. In addition, doing this is not easy, due to objective and subjective reasons. Developing a ship model from the basic design stage requires a lot of factors, including time - a problem that is difficult to meet the needs of ship owners. In fact, the demand of ship owners is often met quickly and harmoniously at shipbuilding facilities. There, the development of new ships is based on the models of ships that have been built and verified. The parameters of the ship and the energy system are calculated based on experience and statistics. The results show that the ships developed in this way all meet technical issues, construction time, ship owners' needs and good operational efficiency. With the use of statistical and data processing methods to analyze, compare and control to build a database to serve the selection of the optimal propulsion system for tankers of a tonnage of over 5,000 dwt.
