the current fleet of tiny  100 ton barges are about to be supplemented by two 500 ton barges.. which will be incredibly more efficient with the 2 barges doing the work of 10 at once.. possibly being more robust to weather?

Throughout the shipping season the expected daily shipping rates were achieved under normal weather operating conditions. However, the highly adverse and very unpredictable weather conditions experienced, particularly in October and November, further highlighted the need for TIG to continue to both enhance port stockpiling arrangements, barge handling and loading processes and to find ways of increasing ship-loading rates in order to compensate for non-weather working conditions at the port.

Measures currently being considered include reviewing the location and number of coal loading points, investment in land-based port loading infrastructure, the construction, delivery and commissioning of two 500t barges to supplement the existing fleet of 100t barges and improving harbour dredging capabilities. Vessel scheduling and management practices are also under review in addition to the split of functions between TIG and the port operator/stevedore.
