no it cant effect cruise ships. They are to large and the cruise will go right through the oil with no problems. so don't worry and have a great vacation
Cruise ships run on diesel fuel to power generators while in port, and heavy fuel oil while sailing.
Yes, cruise ships contribute to global warming. Any transport that uses fossil fuels for power (coal, oil or natural gas) releases carbon emissions into the atmosphere. Cruise ships' engines are usually powered by diesel oil, a fossil fuel.
Sailboats, cruise ships, houseboats, tramp steamers, oil tankers, and there are more that I can't think of right now.
whenever you change the oil
Change the oil filter every time you change the oil.
The engine oil should be changed every 3000-5000 miles
Most ships no matter if they are cruse ships or merchant,battle,tankers,depending on their size can be 50,000 gallons or more,they use very crud oil for fuel,only the military uses nucluer powered vessels.
If you do not drive it often, I would recommend getting it changed every 3 months. That is what many mechanics tell you to do.
Gear oil should be changed every 4,000 to 5,000 miles. Motor oil should be changed every 3,000 miles to keep the engine running clean.
Cargo ships had a broad beam to hold produce. The warships were narrow for speed and manoeuvere.
There are jobs in hospitals and airports, in transportation and in auto repair. There are also jobs on oil rigs, fishing boats, cruise ships, and in tourism.
