ABB launches compact turbochargers for low-speed marine engines

ABB has launched two new turbochargers optimised for small and medium bore two-stroke diesel and gas engines.

{mprestriction ids="1,2"}The A255-L and A260-L models are smaller than previous ABB turbochargers to allow for installation in space-optimised engine rooms. The new turbochargers retain a high-power density within the smaller frame size and incorporate the latest rotor component technologies for maximum efficiency and lower fuel consumption and emissions. according to ABB, the turbochargers also offer low maintenance costs.

ABB’s new A255-L and A260-L turbochargers are highly suited to low pressure dual fuel engines to optimise combustion. 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 A255-L and A260-L turbochargers also facilitate the utilisation of emission abatement technologies for NOx and SOx reduction.

According to ABB, the new A255-L and A260-L turbochargers can reduce the energy efficiency design index (EEDI) of smaller cargo vessels in the size range of 10’000- 40’000 dwt that make use of small and medium bore two-stroke engines. These will typically represent vessels such as bulk carriers, tankers, container feeders and car carriers.

“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 latest emissions regulations,” said Alexandros Karamitsos, head of global sales for Product Line Low-speed Turbocharger, ABB.

“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 optimised on-engine specification. Our drydock-to-drydock service concept will also be available, with no need for intermediate turbocharger inspection.”{/mprestriction}

  • ABB and DNV GL make history with first vessel cybersecurity verification

    In a milestone for the marine industry, ABB’s solutions onboard a large passenger ship have been awarded cybersecurity verification from classification society DNV GL. 

    As a result, this vessel became the industry’s first to achieve system compliance under DNV GL’s framework for integrated cybersecurity.

    The state-of-the-art cybersecurity resilience for the vessel was enabled by close collaboration of ABB, the shipowner and DNV GL during the construction phase at a shipyard in Europe. Cybersecurity management processes will continue during the ship’s operations, with the system’s resilience maintained throughout the lifetime of the vessel.

    “It is vital that the maritime industry focuses on cybersecurity as an essential part of both design and operation,” said Johann Melsted, area manager Benelux & France for DNV GL. “Which is why we are so pleased to be working with forward looking partners, who are prepared to engage with this emerging risk and demonstrate their commitment to tackling cyber threats.”

    In order to achieve sustainable shipping, vessels are increasingly fitted with integrated automation systems and digital solutions. As part of the Fourth Industrial Revolution, the vessel’s systems are more connected than ever before, presenting threat vectors previously unheard of in shipping. This is driving the need for closer and earlier collaboration on cybersecurity between all key stakeholders in the newbuilding process. DNV GL’s Integrated Cyber Security Dependent Systems verification establishes a framework to address cybersecurity levels for the main functions of a vessel – both during construction and in operation.

    While the framework is applicable to any vessel, greater sophistication and deeper integration of operational technology systems in complex vessels such as cruise ships mean that appropriate cybersecurity management is paramount. While digitalisation offers opportunities to measure and manage efficiencies across the entire fleet, securing these data streams is critical to the safety of the vessels’ passengers and crew.

    “ABB recognises the importance of cybersecurity in the marine industry and is working closely with shipowners, yards and classification societies to enhance cyber resilience of ships,” said Juha Koskela, managing director, ABB Marine & Ports. “As vessels become more electric, digital and connected than ever before, it is of vital importance that we equip and empower seafarers with reliable solutions that are cyber secure.”

    The vessel is powered by ABB Azipod electric propulsion system.
