ABB has introduced a new concept to the marine market that offers annual fuel savings of up to 6% by optimising engine speed.
Dynamic AC (DAC) has been introduced as a brand new concept to the industry, having been created by a simple configuration of electrical systems using existing, proven ABB components.
This concept addresses how ships commonly currently run with their generators at a set speed, regardless of the power requirements, which leads to surplus wasted energy. The DAC works by adjusting the rotating speed of the diesel generating sets, allowing the system frequency to vary within the specified range.
Larger ships of more than 20MW power, for example cruise ships, can save up to 6% of fuel per annum by optimising the engine speed through application of DAC says ABB. This equates to approximately 2,000 tonnes of fuel.
DAC joins a number of established ABB products that reduce fuel and maximise efficiency, such as ABB’s Azipod propulsion system and Onboard DC Grid.
“ABB has had great success providing power and propulsion solutions to the cruise industry. Dynamic AC is another tool for cruise companies to build fleets which are more efficient and more environmentally friendly,” said Juha Koskela, Managing Director of ABB’s Marine and Ports business.
