A Study of the Electrical Balance Between Plants According to the Arrangement of Generators

Resumen

The importance of power plants in the Merchant Marine sector is important. Not only are we unable to imagine a merchant vessel sailing without an electrical installation, under no circumstances would it be possible to operate even during their stay in port. In this article, a study is made of the energy balance of different power plants in vessels, taking as a model two types of extreme plants in the Merchant Marine, such as, liquefied gases and vessels with state-of-the-art high speed, such as a combined trimaran transport similar to that of a fast ferry for both passenger and cargo. The most characteristic data of their power plants have been taken by comparing them, on the one hand, liquefied gases, which are characterized on a whole as being vessels of great length, with slow speeds, trips with routes longer than 8 days on average and with very few routes throughout the week and on the other hand, fast-ferry vessels of more or less 100 meters in length, very high speed, very short travel paths and many crossings throughout the day. The distribution of the power plant depends mainly on two factors of operation: the duration of the trip and the number of manoeuvres to be performed per unit time. Due to these factors, not only is the number and power of the electric generators, but also the cost of maintenance, security, etc.
