The port-routeing behaviour of short-sea ship operators; theory and practice

This paper provides an interpretation of a port-routeing pattern of short-sea shipping services which has emerged in recent years. After basic definition. a macro theory of port routeing is presented together with an examination of the business environment of operation. Greater refinement is subsequently added with reference to the behavioural characteristics displayed by a number of individual ship operating companies in port routeing as revealed by a series of in-depth interviews. Specific illustration is provided by the Great Britian-Frances market and the paper concludes by suggesting some factors to influence the development of the future port-routeing pattern.

Vertical integration and its implications to port expansion

ABSTRACT

Over the years many shipping lines have established terminal operation companies, with some set up as independent firms. However, port authorities and local governments have not always welcomed external investment and control with open arms. The economic implications and each stakeholder’s best strategies remain unclear. This study develops an analytical model in order to study the effects of vertical integration, with a focus on shipping lines’ investment in ports’ capacity. Modelling results suggest that vertical integration between terminal operator and a shipping line leads to higher port capacity, port charge, market output and consumer surplus. It also reduces delay costs. All these results suggest that vertical integration can be an important source of synergy for the maritime industry. Although vertical integration increases the participating carrier’s output at the expenses of non-integrating rival shipping firms, our numerical analysis suggests that the overall social welfare is likely to increase. Preliminary empirical tests confirm that vertically integrated ports handle more traffic volumes and are associated with better infrastructure and equipment. Therefore, port authorities and government regulators should carefully review the market competition status as well as port expansion plans.

A model for forecasting future supply of shipping services at Australian ports

This paper aims to develop an integrated model for forecasting both the number of ship visits and their characteristics in the medium and long term. Knowledge of future shipping trends for any port is no doubt important, as the future number of ship visits and their characteristics may have implications for the physical facilities of a port. In addition, more reliance on tonnages as a revenue source has made this knowledge more valuable. The proposed model identifies such major economic determinants as the expected trade throughput, world shipping trends, standards of facilities and future plans of shipping companies/agents. The model examines three possible scenarios for the Port of Melbourne and produces a range of shipping forecasts based on certain assumptions. From the model the major findings were:

world trends in shipping did not have any immediate impact on the shipping trends at the Port of Melbourne;

Future shipping services at the Port of Melbourne in the next 11 years are most likely to be determined by trade demand rather than by technological developments overseas;

there has been no evidence to indicate that the Port of Melbourne has been excluded from the schedule of general cargo ships due to the Port's physical constraints.     

Port or shipping project appraisal under risk .

Investments in ports and shipping today are subject to uncertainty in demand, costs, prices, and technology requirements. As a result, port and shipping project appraisal must consider the risk of project decisions on outcome. The basic concepts of project appraisal under risk are discussed in this paper, and the effects of uncertainties on measures of project performance such as net present value or internal rate of return are reviewed. Applications of the approach advocated are presented in a follow-up paper.
