Cruise Ship Crankshaft

The grid-like structure of cruise-ships.

Cruise ship crankshaft. The crankshaft from a cruise-ship diesel engine can be replaced in as little as 12 hours during a scheduled harbor stop and without cutting the watertight bulkheads thus not impacting operations. First proposed in 2019 the new state-of-the-art terminal is projected to cost 125 million to build and when completed it will provide a terminal to handle the worlds largest cruise ships. A 4 stroke engine can be installed on the ship to produce electrical power and also to propel the ship usually in small size vessel.

Excellent factory machine and technology. Wartsila 12V46 Length of crankshaft 9 meter Weight of crankshaft. Prior to the exchange the existing structures on the ship were reinforced and reference points were added to show the original position of the engine.

The crankshaft is linked to the propeller which would turn faster the faster the pistons moved. At 228081 GT she is the largest cruise ship in the world by gross tonnage surpassing her sister ship Harmony. This type of propulsion is very similar to traditional diesel engines.

On the other end propeller is fitted which pushes water and hence moves the ship. The old crankshaft was damaged so needed to be exchanged and refurbished. 5 CRANKSHAFT REPLACEMENT LINE BORING REBUILD FOR WARTSILA 12V46 ENGINE CAREFUL PLANNING AND EXECUTION.

TUI Cruises Mein Schiff 6 has been fitted with a new crankshaft for one of its four Wartsila engines at a wetdock in Germany. Most new cruise ships use diesel-electric engines. Modern cruise ships tend to use medium speed 4-stroke trunk engines to drive alternators which provide power to electrically driven propulsion units.

Are equipped with diesel engines. Goltens met with the cruise lines technical management and consultant and agreed. I hope this gave a small peek into some of the challenges of the shipping industry.
