Expansion in cargo handling: geographical and functional issues

Intense co-operation as well as severe competition are two characteristics of the current sea-port cargo-handling sector. This paper contributes to remedying the lack of understanding of the effects that such strategies may have on operating conditions in the sector. It analyses the geographical strategies pursued by the major operators up to 2006, as well as the functional directions in which co-operation is sought. It appears that most domestic ventures for the majority of container-handling operators are non-co-operative ones, except for PSA and HPH. Abroad, all of the cargo-handling operators except DPA/CSXWT have more co-operative than non-co-operative ventures. As to nationality of acquired subsidiaries, it is observed that most co-operative ventures have two nationalities involved. In terms of functional direction of operations, the major container-handling companies, except APM Terminals, start up most of their co-operative ventures with non-cargo-handling partners. Furthermore, it can be observed that HPH, APM Terminals, P&O Ports and DPA/CSXWT have started up, acquired or merged with more limited companies in cargo-handling than in non-cargo-handling activities. Most of the non-horizontal partners in cargo-handling ventures appear to be industrial or investment companies. PSA's, Eurogate's and DPA's non-cargo-handling ventures predominantly are in logistics. Combining geography and functional direction graphically shows that the major operators have had very diverging strategies. The two extremes are Eurogate, with a network which is solely focused on Europe, and P&O Ports, covering all continents.

Productivity change in Nigerian seaports after reform: a Malmquist productivity index decomposition approach

ABSTRACT

During the 1990s, Nigerian seaports were considered inefficient, unsafe due to massive cargo theft (wharf rat phenomenon) and one of the most expensive port systems in the world. This resulted in long turnaround times for ships and increased container dwell times. As a result, port operations were transferred to the private sector through concession contracts. This paper employs a Malmquist productivity index (MPI) technique to benchmark pre-and post-reform total factor productivity growth of the six major Nigeria seaports (Apapa, Calabar, Onne, Port Harcourt, TinCan Island and Warri) for the period 2000–2011 which represents six years before (2000–2005) and six years after (2006–2011) the reform. The results indicate progress in technical efficiency of the ports after reform but deterioration in technological progress. Overall productivity growth was higher in the pre-concession period compared to the post-concession period. The source of pre-concession period productivity growth was technological progress while the change in productivity of the post-concession period is generated by an increase in scale efficiency. This suggests that concessionaires have not brought in the much anticipated investment in modern technology to drive port efficiency. The ports of Calabar and Apapa experienced the highest productivity growth while lowest result was Onne.     

Structural changes in logistics: how will port authorities face the challenge?

The market environment in which ports operate has changed dramatically, and this continuous process of change raises questions on the role of port authorities. This paper discusses the impact of some structural changes in international trade, transport and shipping on strategic and operational issues in the framework of port management. The central hypothesis put forward is that a successful port (authority), like a successful actor, must be prepared to constantly adopt new roles in order to cope with the changing market environment. The content and strategic scope of these new roles are highlighted, especially with regard to the European container port system.     

Towards a common ports policy? EU-proposals and the ports industry's perceptions

This paper discusses the European Union's (EU) proposals to improve the efficiency and infrastructure of European ports, and investigates the extent to which these proposals are welcomed by the ports industry. On the one hand, the analysis of the recent EU policy developments makes apparent that the EU is increasingly impinging upon the port industry's life. On the other hand, the findings of the semi-structured interviews with the industry's representatives suggest that although port authorities and port operators remain in principle against a coherent common EU ports policy, the industry believes that certain EU initiatives can enhance the competitiveness of the maritime transport system.

Italian ports: towards a new governance?

The adoption in 1994 of the law n. 84 introducing the landlord port model marked the starting point of a prime period for the Italian port industry. It contributed to the national port industry renaissance: Italian ports became again the leaders in the Mediterranean basin, both as gateway ports and as transhipment ports. Looking back to its 15 years of enforcement, critical aspects and weaknesses have been observed. The incentive to reflect on the governance structure of ports and on the changes affecting the whole logistics transport chain is driven by the relative and absolute loss of position of Italian ports with respect to their competitors of the North as well as of the South European range (and the ports of Northern Africa which are expected to compete fiercely in the coming future). Considering only the container traffic, from 2003 to 2008 the market share of Italian ports decreased from 20.7% to 15.7% in favor of its main European competitors. The loss of attractiveness of Italian harbors is a clear symptom of the several difficulties national ports face in dealing with the rapid changes affecting the port industry. This paper discusses the bill presented by the Italian Government concerning the ports governance reform.     

Cargo handling productivity. Part 2. The findings

This is the second of two papers on cargo handling productivity presenting the results of the model developed int he first [1] which had been designed to test a productivity measurement method with cross-sectional empirical data. Four productivity measures were employed. Two related cargo handling to time, with labour brought into the analysis as an independent variable. The third productivity measure expressed total throughput as an aspect of labour productivity, while the final measure was a full productivity index developed by relating output to both capital and labour.

The productivity measurement technique demonstrated that this method can be used for cross-sectional studies and can cope with and allow for variation in non-controllable extraneous factors, thus proving useful for policy decision-makers in shipping lines and/or port authorities.

This paper presents the results of the prodictivity analysis for which the analytical design was decribed in Part 1. The first section briefly restates the productivity indices developed. The principal results and tests on these measures are present in Section 2 with conclusion following in Section 3.     

The Port of Melbourne Authority's pricing policy: its efficiency and distribution implications

The objective of this paper is investigate the extent to which the new (revised) pricing policy has improved the level of efficiency at the Port of Melbourne and to assess the contributions of the underlying factors of port efficiency. Further, it attempts to examine the distribution implications of the pricing policy between the major port users (i.e. shipowners and shippers) and its revenue implication for the Port of Melbourne. Using a conceptual framework derived from economic theories, in-house data and responses from the port users, the study reveals that the efficiency impact has been considerable and varied between berths; land transport links and crane productivity improvements were the major factors of the port's overall efficiency; the initial losers have been the shipowners and initial gainers the shippers; however, the gains have been limited and in some cases have been offset by the introduction of higher port service charges; in the long run it is likely that the shipowners and shippers' situations will be unchanged while the Port of Melbourne will lose revenue due to improvements in berth productivity uncompensated by greater traffic volume.
