Shipboard electrical power generation is generally for ship service power supported by emergency generators. In the case of a prime mover-driven propulsion system, ship service electric power is generated by ship service generators. This chapter summarizes US and IEC shipboard power generation and distribution levels at 50 HZ and 60 HZ.
In general, ships’ operations require power lower than the installed generator capacity. However, when the generator is operated at a low load, its efficiency decreases. In this study, based on actual operation data, the load requirements for each operation mode were analyzed, and a diesel-generator-based power system was designed.
Ship service generator size, rating, and quantity requirements are very well defined by IEEE 45, American Bureau of Shipping (ABS), and USCG with some slight differences. Abstract Shipboard electrical power generation is generally for ship service power supported by emergency generators.
These systems are designed to replace a conventional diesel powertrain installed on board a container ship. The fuel consumption, according to the ship load profile, is calculated and the analysis on the masses and volumes of the fuel storage tanks and of the ammonia powertrain systems is performed.
