Fuel costs and reliability are two of the most prominent issues facing ship owner/operators today. With new environmental legislation these factors will only increase in importance. Meanwhile, demand for seaborne trade is expected to grow.
Managing the performance of a ship’s engines increasingly requires information on a real-time basis. An optimized engine, where all cylinders are working in balance, uses less fuel and incurs less wear. An engine out of balance can quickly develop thermal and mechanical stress points that drag down fuel economy and increase maintenance costs.
ABB designed their Cylmate system specifically for continuous monitoring of the performance of two-stroke diesel engines used both in marine and stationary applications. Pressure transducers provide real-time measurement of compression in each cylinder. This combined with precise measurements of crank shaft position provide a detailed picture of the engine’s operation in real time so that combustion pressure can be tuned stroke by stroke.
Using Cylmate can reduce fuel consumption by 1 to 2 percent. That may not sound like a lot, but when you consider that large ships measure fuel consumption in tons per hour, even a small percentage gain will yield real savings. In fact, the payback time on a typical monitoring system is less than one year based on improved fuel economy alone.
Like other modes of transportation, ships are becoming more sophisticated with the majority of them equipped with electronically controlled engines. As this has become the industry norm, continuous combustion pressure measurements have become standard.
One of the largest and most advanced container vessels today such as the massive Maersk “Triple-E” class rely on Cylmate to optimize engine operations and keep costs down.
But the advance of engine technology is not limited to oceangoing vessels. Stationary engines used to generate electricity face the same challenges in terms of fuel efficiency and uptime.
ABB’s Measurement & Analytics have also helped the Barbados Light & Power company (BL&P) serve 280,000 residents with electricity primarily from diesel-powered generators. BL&P has installed two Cylmate systems at their Spring Garden power station to monitor engine performance and ensure a high level of reliability. The system has given them new insights into engine operations, for example by identifying conditions that could lead to a worn cylinder liner before experiencing a costly failure.
Whether on land or at sea, diesel engines are likely to be a vital power source for many years to come, but they will face increasing performance challenges from an economic and a regulatory standpoint. Technologies like combustion pressure monitoring and control is a vital tool in meeting these requirements.
