Creator's Key Takeaways
one of the questions that is often put to the crew on a cruise ship is how does the ship get electricity
in the 1980s it was estimated that an ocean liner the size of the 70 000 gross ton QE2 generated enough electricity every day to power the city of Southampton
the most common power plant on cruise ships at the moment are diesel Electric Systems
cruise lines are making steps to Source Greener fuels but more needs to be done and quicker to meet the urgency needed to fight climate change

And while battery technology is improving at a great rate, you’d still struggle to find one that could allow for longer distance voyages while still powering a city, and fitting on a ship, with space left over for all of the passenger and storage spaces that are needed on board. The most common power system on ships at the moment is diesel-electric. This means that diesel engines on board the ship produce electricity. This electricity is then used to power the different services on board. This includes powering the propellers or pods. This is a form of indirect drive, where the engines are not directly attached to the propellers to drive the ship. This is the opposite of the reciprocating engines of old. The old reciprocating engines, and even the first steam turbines were direct drive. This meant that the engines were attached directly to the propeller shaft, or paddle wheel in the older ships, and as the pistons turned, this turned the propeller or paddle wheel shaft. Direct drive engines are the simplest way of powering a ship, but they aren’t the most effective. It was discovered in some of the earlier steam turbine ships, that the speed at which the propeller was most efficient and the speed at which the turbine were most efficient, were different. This led to serious vibration issues when the ship was run at speed. Indirect drive engines overcome this problem. Though they are a little more complex and require more machinery to convert the electricity to allow it to run the ship, they are more efficient overall. They allow both the engines and the propellers to run at their most efficient speed by separating the process of creating power from the process of using that power.
