The aim was to provide a cost effective compliant solution that minimised operational impact, this was achieved by:
The operation was improved by providing additional emergency stops and fault indication on the vessel’s bridge, one button press now started the drives and reliable indication of actual drive speed is provided. There was less harmonic distortion observed on the electrical supply generation system and reduced voltage spikes. The maintainability of the converters has been improved by with the inclusion of a low maintenance speed feedback encoder to allow easy access to parameter editing and monitoring of operational variables. Due to clever design there was reduced manual handling when changing major components and the auxiliary electrical components are now readily available current generation parts. Future changes can now also be easily implemented via the local control panel or a laptop.
