Combustion pressure under control at Mærsk Mc-Kinney Møller

Introduction

The 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.
