Marine engineering specialist ABB Turbocharging has announced two new turbochargers for small and medium bore two-stroke and dual-fuel engines and upgraded its ABB Ability Tekomar XPERT engine monitoring platform.

In response to increasing demand for compact and efficient turbocharger technology for marine engines, ABB Turbocharging has launched the new A255-L and A260-L turbochargers. Scaled down from the proven and reliable A100-L and A200-L designs, the new turbocharger models offer a smaller size and best in class performance while retaining key design features incorporating the latest rotor component technologies. Their compact design allows installation flexibility in modern, space-optimised engine rooms.

Delivering the high-power density normally expected from larger turbocharger alternatives, the new A255-L and A260-L offers the marine engine market, turbocharger technology with more power density with a smaller frame size. For ship owners, these new turbochargers deliver high efficiency, lower fuel consumption and emissions. They also offer lower maintenance costs, allowing for optimised 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 latest emissions regulations. 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.”

ABB’s new A255-L and A260-L turbochargers can be used on low pressure dual fuel engines to optimise combustion, improving engine efficiency and allowing for the 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 A255-L and A260-L turbochargers also facilitate the utilisation of emission abatement technologies for NOx and SOx reduction.

Due to the significant efficiencies achieved, 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- 40,000dwt 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.

ABB Turbocharging has also upgraded its digital platform ABB Ability Tekomar XPERT, for use on a fleet-wide scale. Tekomar XPERT for fleet incorporates all standard features found in the original Tekomar XPERT application with additional fleet functionality specifically developed to support middle and top management decisions.

When installed on every vessel in a fleet, Tekomar XPERT can quantify deviations in engine performance and provide simple guidance on running engines at optimum levels of efficiency. The software also offers recommended corrective actions for the realisation of potential fuel oil savings.

Deviations from actual service performance to shop trial reference are converted to a fuel penalty. This fuel penalty is broken down in reference to single parameters. For each parameter there is a recommended action to bring the performance back to optimum and realise the fuel oil saving. ABB Turbocharging claims following the advice provided by the software can result in significant fuel savings of typically 0.5 to 3 tonnes of fuel per day, per vessel.

This type of advanced diagnostics, combined with the sharing the information with onshore office, also allows ship operators to immediately focus on fixing potential problems, rather than initially spending many hours analysing them. Tekomar XPERT for fleet allows company-wide engine performance assessment with controlled and consolidated analysis across a fleet. It facilitates the benchmarking and ranking of engines, vessels and fleets and the user-friendly dashboard can be customized according to role.

Beat Güttinger, Head of Tekomar for ABB Turbocharging, said, “Tekomar XPERT for fleet makes keeping an overview on engine performance easy undertaking for fleet managers, ship operators and owners. This smart digital solution with the newly introduced Engine Health Index offers marine customers an instant overview of their entire fleet. Whether an operator oversees five ships or many more across an international fleet, they can benchmark their fleets, ships and engines and quickly drilldown into more details to identify potential low performers or late reporters, Tekomar XPERT for fleet takes away the time consuming analysis of engine performance and allows operators to immediately focus on fixing problems to reduce fuel consumption and minimizes downtime and maintenance costs.”

Tekomar XPERT can be used with any marine main and auxiliary engine, irrespective of manufacturer, type, age or size. There is no hardware to install and the application can be dropped into the shipping company’s normal IT system, accessible via PCs, tablets and mobiles.
