Yes, the need to keep the generators going.

Electricity on ships is primarily produced using generators powered by various sources, such as diesel engines, gas turbines, or even renewable sources like solar panels and wind turbines. The generators convert mechanical energy into electrical energy, which is then distributed throughout the vessel to power systems, equipment, and lighting. Some ships also utilize batteries for energy storage, enabling a consistent power supply even when generators are not in operation. Additionally, modern ships may employ hybrid systems to optimize fuel efficiency and reduce emissions.
Cruise ships run on diesel fuel to power generators while in port, and heavy fuel oil while sailing.
The answer is suggested in your question. Cruise ships, like most big boats, have generators on board that provide the electricity. Usually big diesel engines. Depending on the size of the ship, there could be four or more.
Ships generate electricity for various systems using onboard diesel generators or gas turbines. These generators are powered by fuel, which is converted into mechanical energy to produce electricity. Some ships also utilize solar panels or wind turbines to supplement their energy needs.
Ships are sometimes built in pairs to reduce costs through economies of scale in production, maintenance, and operation. Building identical ships also allows for standardization of parts, training, and procedures, making it easier to manage and operate the vessels efficiently. Additionally, having sister ships can provide redundancy and flexibility in fleet deployment.
Diesel generators are used to generate electricity. They are used as an emergency supply of power, where access to power is limited and, even, on ships so that they can carry more cargo.
It's a generator that creates 400hz AC signals, instead of 50 or 60hz. 400hz is often used on ships, because the equipment (generators, transformers) can be made much smaller.
You can buy a power generator from Resource Steel Homes check out the website www.customsteelframes.com/resource.htm they can ship it to you or any part of UK mainland
Ships can use a variety of energy sources, including diesel fuel, heavy fuel oil, liquefied natural gas (LNG), and electricity from onboard generators. Some ships also use alternative energy sources such as wind or solar power to supplement their traditional fuel sources.
