t is not the age, but the actual ageing that should be leading when replacing modular frequency converters, according to dredging and offshore system integrator Bakker Sliedrecht. The company is changing its approach from time-based to conditionbased maintenance, and the first offshore crane ship is already being successfully maintained in this way.
Vessels with electrically-driven motors, but also cranes, terminals, pumps, and rollers use modular frequency converters to control their speed and power. Each frequency converter contains a capacitor bank in which the capacitors are subject to ageing. Replacing them is a time-consuming job. It can take between seven and eight hours to replace the capacitors of a single module
