 JAPANESE DEBUT FOR A255-L TURBOCHARGER

JAPANESE DEBUT FOR A255-L TURBOCHARGER

Tuesday, June 22, 2021 

Japanese engine builder Makita has selected ABBs latest low-speed turbochargers for an engine ‎being built for a chemical tanker, marking the first time that a Japanese-built engine will feature the ‎compact, powerful A255-L turbochargers.

The turbochargers will be applied on a 6S40ME-B9.5 engine built by Makita which manufactures MAN ‎engines under the license. The A255-L is designed to provide high turbocharging efficiency from a ‎small unit, reducing overall engine size and giving ship designers greater flexibility in engine room ‎design for small bore two-stroke marine engines.

‎The engine and A255-L turbochargers have completed shop tests and will be delivered to the shipyard ‎today. Makita’s tests confirmed good turbocharger performance across the entire load range, with ‎turbocharger efficiency exceeding 70%.

Makita is a leading builder of small two-stroke engines and places a strong focus on reliability and ‎economic performance. The A255-L is designed based on ABB’s long-established A200-L and ‎provides benefits both in capex and opex by reducing the turbocharger footprint. The turbochargers are ‎designed to be compatible with NOx and SOx abatement technologies, helping shipowners comply with ‎future regulation on air pollution and greenhouse gas emissions.

‎A Makita spokesperson said: “As an engine manufacturer, downsizing, weight reduction and high ‎turbocharger efficiency are very important. A highly reliable turbocharger is particularly important for ‎chemical tankers as service opportunities are limited. The A255-L fully meets our needs. The high ‎efficiency of the turbocharger will have a positive effect on fuel consumption and contribute to making ‎the engine more competitive in the global market.”

‎Alexandros Karamitsos, Head of Global Sales Low-Speed Turbochargers, ABB, said: “Japan is a key ‎shipbuilding market and Japanese engine builders are renowned for their high standards and attention ‎to detail. Coming at a time when cost pressures are increasing, the order from Makita demonstrates ‎both the high performance and the competitiveness of A255-L.”

‎The A255-L is designed mainly for smaller vessels of 10,000-40,000 dwt that use small bore two-stroke ‎engines. Typical vessels include bulk carriers, tankers and car carriers, many of which are built at ‎Japanese shipyards.

‎ABB Turbocharging is a global leader in turbocharging technologies and digital optimization solutions ‎for engines ranging from 500 kW to more than 80,000 kW. Its installed base of more than 200,000 ‎turbochargers and a network of more than 100 service stations worldwide‎.
