The Wärtsilä RT-flex96C is a two-stroke turbocharged low-speed diesel engine designed by the Finnish manufacturer Wärtsilä. It is designed for large container ships that run on heavy fuel oil. Its largest 14-cylinder version is 13.5 meters high, 26.59 meters long, weighs over 2,300 tonnes, and produces 80.08 megawatts.
The size of the different types of engines is an important factor in selecting what will be installed in a new ship. Slow speed two-stroke engines are much taller, but the footprint required is smaller than that needed for equivalently rated four-stroke medium speed diesel engines.
The amount of fuel carried on a container ship varies based on the engine capacity and size of the ship, which themselves are a function of the particular trading route the ship operates in and ...
This design results in a very long engine, therefore it has only been used as marine propulsion engines in large ships. The only straight-14 engine known to reach production is part of the Wärtsilä-Sulzer RTA96-C family of 6-cylinder to 14-cylinder two-stroke marine engines. This engine is used in the Emma Mærsk, which was the world's ...
The vessel's main engine is a two-stroke MAN Diesel 11S90ME-C diesel engine, which has a height of 15.5 m (51 ft), a length of 25 m (82 ft) and a breadth of 11 m (36 ft). [ 2 ] [ 4 ] The engine has a maximum continuous rating of 62.5 MW (83,800 hp) at 82.2 rpm and a normal continuous rating of 56.25 MW (75,430 hp) at 79.4 rpm.
A marine steam engine is a steam engine that is used to power a ship or boat. This article deals mainly with marine steam engines of the reciprocating type, which were in use from the inception of the steamboat in the early 19th century to their last years of large-scale manufacture during World War II.
Container ships are distinguished into 7 major size categories: small feeder, feeder, feedermax, Panamax, Post-Panamax, Neopanamax and ultra-large. [27] As of December 2012, there were 161 container ships in the VLCS class (Very Large Container Ships, more than 10,000 TEU), and 51 ports in the world can accommodate them. [28]
The Triple E class is a family of very large container ships with a capacity of more than 18,000 TEUs, which are owned and operated by Maersk Line. With a length of 399.2 m (1,309 ft 9 in), when they were built they were the largest container ships in the world, but were subsequently surpassed by larger ones such as CSCL Globe. [2] [3]
