- Description
- The shipping industry is reliant on port authorities for the facilitation of safe entry and departure of ships at the ports. This role can not be fulfilled without the assistance of harbour tugs which are run by the marine operations section of the Transnet National Ports Authority. The tugs have to be safe and efficient in the process of pulling and pushing ships around the harbour. Harbour tugs are expensive to acquire and to maintain. The marine operations business has to make appropriate choices of tug propulsion design in order to realise the benefits of the tugs acquired by the ports authority. This can be achieved by analysing the current tugs that the operations are using, which will then serve as valuable information when the time for asset replacement is due. The researcher chose to use the two tug propulsion designs currently used by the Port Elizabeth harbour tugs as a basis for this analysis. The analysis links the three factors of maintenance management, equipment efficiency and equipment safety, to the minimisation of operational costs as perceived by the tug personnel, the pilots and the marine managers. This study seeks to verify the link between these factors and the perceived minimisation of operational costs. Available literature was reviewed and data was collected using a suitably designed questionnaire for this research. This research paper has led to recommendations that should inform the tug acquisition decisions and raise the awareness of the marine employees to relate the factors set out above to minimise operational costs.
