ABB today announced that it has opened two-stage turbocharging to a wider market with a new frame size for the Power2 800-M solution, a development ABB says will enable more vessels to benefit from the high efficiency and fuel savings.

The Power2 800-M is said to provide an overall turbocharging efficiency of more than 75 percent - approximately 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," says ABB.

Power2 800-M is set for its first commercial application on an icebreaker that will serve the Yamal LNG project in the Russian Arctic, with fuel efficiency and reliability noted to be the two major deciding factors in the design specification.

Power2 800-M is set to be launched mid-2017, with ABB noting that, with the new frame size, Power2 845-M is now applicable to an increased range of ship propulsion solutions, opening up the efficiency and operational benefits to a wider range of vessel types, including 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.

"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," said Marco Burgwal, Product Line Manager for Medium-Speed ABB Turbocharging.

"In extending our Power2 portfolio, we are achieving our product development goal of bringing these values of high efficiency for fuel savings, system compactness and flexible operation to a greater number of engine builders' customers."

Earlier this month, Ship & Bunker reported that two DFDS RoRo vessels will receive high-performance A270-L turbochargers, which ABB says will reduce bunker consumption and associated emissions.
