Combustion pressure under control at Mærsk Mc-Kinney Møller

Cylmate® pressure transducers

Share this page

World’s largest container ship uses ABB’s Cylmate pressure transducers to optimize performance of diesel engines.

Introduction


Maersk_McKiney_MøllerThe recently launched largest and most efficient container ship uses ABB pressure transducers to measure the combustion pressure of its electronically controlled diesel engines. Twin 8-cylinder MAN diesel engines and two propellers drive the ship, named Mærsk Mc-Kinney Møller.

This is the first ship among Maersk’s “Triple-E” class of container vessels, capable of carrying 18,270 twenty-foot standard containers. The Triple-E stands for the class’s three design principles: economy of scale, energy efficient and environmentally improved. Currently, only a few ports have gantry cranes tall enough to fully load the ship.

Cylmate pressure transducers, suitable for both marine and power plant applications, measure the combustion pressure in each cylinder, continuously and in parallel, under all load conditions. The pressure transducers never need recalibration and they permit blow-through cleaning to prevent any build-up of combustion residues. Pressure measuring accuracy is 0.5% over the full range.

The unique and reliable Cylmate pressure transducer has proven its maintenance- and calibration-free performance during years of continuous operation.

Cylmate pressure transducers save money by enabling the tuning and controlling of the combustion pressure stroke-by-stroke. Cylmate pressure transducers used on electronically controlled diesel engines provide improved energy efficiency and lower the risk for off-hire costs.

The unique and reliable Cylmate pressure transducer has proven its maintenance- and calibration-free performance during years of continuous operation.

Engine designers, engine builders, shipyards and shipowners enjoy major benefits with Cylmate pressure sensors

By using Cylmate pressure sensors you will get the key knowledge for obtaining optimum and reliable engine performance:
– reduced fuel consumption
– an engine in good balance will avoid thermal and mechanical
over-loads by assuring that the power distribution is equal
between the cylinders
– an optimized engine will make it easier to comply with
environmental regulations
