The Southland/Otago region is expected to significantly increase its exports of Forest products over the next three decades. It is envisaged that at least 90% of this increase will flow through Port Chalmers. The effects of this increased throughput on the Port has been evaluated using a number of different factors, i.e. loading rates, number of berths and vessel draught in Conjunction with the branch of operations research known as queuing theory. This combination has been used to determine the cost of delays to shipping as a result of Port congestion, i.e. waiting time and costs.
The results were that a considerable strain will be placed on the existing berthag by 1991 and that to alleviate serious congestion an expansion of port facilities must be undertaken.
To effectively cope with the projected throughput it was concluded that by 2001 a further three berths need to be provided and that by 1996 the Port should be introducing a double shift loading operation for forest products.
It appeared that harbour depth had very little importance if a high loading rate was used, the implication is that the loading rate governs Port throughput. There is unfortunately a very high labour cost which tends to diminish the savings in waiting costs made by having a double shift loading operation.
