First 2-stroke gas engine taking Quantum 1-stroke further
A year ago, DNV launched its container ship concept – Quantum. This concept ship was designed to stir up a debate about shipping innovation. Over the past few months the engine manufacturer and the class society have worked closely together to move the concept one step nearer to becoming an actual ship.
Recently in London, DNV and MAN Diesel & Turbo announced the new Quantum 9000 concept container ship. One of its major improvements is related to the engine. MAN Diesel & Turbo has developed a gas-fuelled two-stroke ME-GI engine. In addition to having dual-fuel engines, Quantum 9000 achieves full fuel flexibility and at the same time meets the upcoming ECA requirements. The ship’s energy efficiency is also better than that of conventional existing container ships.
In addition to the use of gas, the engine solution includes waste heat recovery to improve the energy efficiency and exhaust gas circulation to reduce the emissions.
A number of other improvements have been made possible by adopting a twin island arrangement, such as increased cargo capacity and reduced need for ballast water. Also the improved sightline from the bridge, which contributes to increasing the safety in operation, and the minimum fuel consumption, can be mentioned.
The ship’s LNG fuel capacity will be similar to that needed to sail from East Asia to the east coast of the US – still without any loss of cargo space.
