ABB Launches New Compact And Efficient Turbocharger For Low-Speed Marine Engine
ABB Turbocharging has launched the new A255-L and A260-L turbochargers, as the demand for compact and efficient turbocharger technology for marine engines was increasing, these turbochargers are optimized for small and medium bore two-stroke diesel and gas engines.
The new turbocharger models, A100-L and A200-L designs are proven to be reliable and also offers a smaller size with the best class performance while retaining key design features incorporating the latest rotor component technologies. The installation flexibility in modern, space-optimized engine rooms is possible due to their compact design.
The new A255-L and A260-L offer turbocharger technology with more power density with a smaller frame size which is generally expected from a larger turbocharger, in the marine engine market. For ship owners, these new turbochargers deliver high efficiency, lower fuel consumption and emissions. They have lower maintenance costs and also allows optimized total cost of ownership.
Alexandros Karamitsos, head of global sales for Product Line Low-speed Turbocharger, ABB commented: “We believe further focus will be placed on turbocharger efficiency in the future, alongside higher compressor pressure ratio demands, to enable two-stroke engines to reach their full potential. Our A255-L and A260-L turbochargers will support this demand, delivering the highest levels of turbocharger efficiency and power density while enabling small-bore two-stroke engines to achieve lower fuel consumption, and complying with the latest emissions regulations.”
Karamitsos continued “The A255-L and A260-L turbochargers are designed to operate on all fuel types and on engines specified for both IMO Tier II or Tier III emissions levels. Similar to other turbocharger products in our A200 series, a full range of matching components will be available to ensure an optimized on-engine specification. Our drydock-to-drydock service concept will also be available, with no need for intermediate turbocharger inspection.”
Global Sulphur Cap which will be implemented by January 1, 2020 will be enforcing a maximum permissible sulfur content of 0.5% for any fuel used on board ships (except for vessels using scrubber technology). Liquefied natural gas (LNG) is preferred by an increasing number of ship owners. LNG can be used on 2-stroke low pressure and higher pressure dual-fuel engines.
The new A255-L and A260-L turbochargers launched by ABB offers a feature that it can be used on low-pressure dual fuel engines to optimize combustion, which will improve engine efficiency and will allow reduction of GHG emissions. The high turbocharging efficiency provided by the new A255-L and A260-L turbochargers ensures that high air-fuel ratio is maintained in high-load operation, thus reducing the tendency for fast combustion which can adversely affect operation and emissions. The utilization of emission fading technologies for NOx and SOx reduction are also some features provided by A255-L and A260-L turbochargers.
The new A255-L and A260-L turbochargers can reduce the energy efficiency design index (EEDI) of smaller cargo vessels up to size range of 10’000- 40’000 dwt because of the significant efficiencies, that make use of small and medium bore two-stroke engines. The vessels such as bulk carriers, tankers, container feeders, and car carriers are represented by these turbochargers.
