ABB Turbocharging will launch in mid-2017 a new frame size for its two-stage turbocharging solution, Power2 800-M, extending the benefits of high pressure ratios, increased turbocharging efficiency and fuel savings to a wider scope of medium-speed engine configurations, the manufacturer said.
 
The new frame size, Power2 845-M, applicable to an increased range of ship propulsion solutions, will open up the efficiency and operational benefits to a greater spectrum of vessel types, said ABB Turbocharging. These may include OSVs, drill and semi-submersible vessels, RoPax, ferries, as well as medium-sized tankers, container ships and bulk carriers, for main engines, DE and auxiliary engines.
 
According to the manufacturer, the Power2 800-M was designed to set new standards in turbocharging performance, with a design that achieves an overall turbocharging efficiency of more than 75 percent, some 10 percent higher than conventional single-stage models. For vessel owners, this can translate into yearly six-figure savings in fuel as well as up to 60 percent lower NOx emissions. In addition, designers were able to optimize the layout with dedicated components for two-stage turbocharging application, resulting in a smaller footprint.
 
Ensuring straightforward service and maintenance while minimizing downtime was another design criteria, ABB said. Power2 800-M comes with an extractable cartridge for ease of service, reducing overhaul time by 30 percent.
 
Power2 800-M’s first commercial application will be on an icebreaker to serve the Yamal LNG project in the Russian Arctic, a project for which fuel efficiency and reliability were the two major deciding factors in the design specification, ABB explained. Other key considerations were operational flexibility as well as performance in extreme environmental conditions as the vessel will operate in temperatures down to -50°C. 
 
ABB Turbocharging said other forthcoming marine applications of Power2 800-M include a Danish-built purse seiner/trawler to operate in the North Atlantic, North Sea and Norwegian waters, as well as a car and passenger ferry to be built in Finland for a Danish operator.  Further Power2 800-M units are also on order for marine and stationary power applications.
