ABB sets two-stage turbocharging available to more vessels

ABB announced that, from mid-2017, it will launch a new frame size for its Power2® 800-M two-stage turbocharging solution, that will allow more vessels to benefit from the high efficiency and fuel savings.

The new frame size, Power2 845-M, applicable to an increased range of ship propulsion solutions, will open up the market to a greater spectrum of vessel types, such as 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.

Marco Burgwal, Product Line Manager, Medium-Speed, ABB Turbocharging comments: “Two-stage turbocharging responds to the most important technology value drivers in the development of modern four-stroke medium-speed engines, reaching beyond the parameters of single-stage turbocharging.”

Power2 800-M’s design 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 significant cuts in emissions – up to 60 percent lower NOx emissions.

Attention was also given to optimizing the layout with dedicated components for two-stage turbocharging application, resulting in a 20 percent smaller footprint than a solution based on conventional single-stage components.

Ensuring straightforward service and maintenance while minimizing downtime was another design criteria. Power2 800-M comes with an extractable cartridge for ease of service, reducing overhaul time by 30 percent.

Power2 800-M will first be commercially applied on an icebreaker to serve the Yamal LNG project in the Russian Arctic. 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, and 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.

The solution will also be presented at Nor-Shipping, from May 30 to June 2, at Hall E 03-13.
