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.

An analysis of the pricing system in the Greek-Italian coastal routes

Price discrimination is practiced by oligopolistic coastal shipping companies in the 'unregulated' Greece-Italy routes in the year 2002. Investigation has been carried out 'per route'—in a doctoral thesis—instead of 'per market' which was the so-far erroneous approach of shipping economists. This is so for a host of differentiating factors play a considerable and non-negligible role (like geography, distance, demand, seasonality and others). Service—and price-discrimination—in coastal shipping is affected also by the predetermined ship design which thus is a special feature—but not exclusively—in coastal shipping. Companies in the Adriatic Sea try to extract the greater possible value of the user's willingness to pay, peak and off-peak, group and ungrouped, for social groups (clubs, families and students). Marketing and economics interfere in a complicated—far from the nice world of theory—situation, where maximization of revenue and profit, capacity utilization, intense seasonality and high fixed cost (common and joint costs as well) are a few of the factors that interplay. This paper can be considered as a case study for applied pricing. Excess capacity is also a strategic factor affecting pricing. It is our opinion that the analysis here gives for the first time a complete theoretical and practical account—based on the price lists of the companies—of the pricing policy of the ferry boats running in the Adriatic Sea belonging to coastal shipping companies connecting Italy with Greece and Greece with the European Union (EU). We believe this work to be useful for maritime Europe.     

Demographic indicators of the relative need for artificial reefs in Florida

Abstract

Artificial reef development involves pfonning from a number of perspectives including biological, océanographie, engineering, and social. This article reviews previous studies and identifies demographic variables that affect the use of artificial reefs by recreational anglers. An index of relative demand was created employing eight components: number of coastal county resident boat anglers, nonresident boat anglers, tourist boat anglers, nonboat anglers, number of fishing clubs, number of charter/party boats, number of registered pleasure boats, and the rate of county population growth. By comparing the magnitude of the index to the number of existing artificial reefs off of Florida's 35 coastal counties, an estimate of relative need was graphically portrayed on a state map. Indian River county on the Atlantic coast and Hernando, Hillsborough, Pasco, Citrus, Levy, Lee, and Charlotte counties on the central Gulf coast are the areas with the greatest demand relative to existing reef supply.

Forecasting short-term freight rate cycles: do we have a more appropriate method than a normal distribution?

General economists, as well as Maritime economists, assume that the time series they forecast follow normal distribution, and data is independently and identically distributed around the mean. This paper contests this assumption with the aid of three sets of time series: (1) The Dry Cargo Freight Index, 1741–2005: in this series the data deviate from the mean by more than three standard deviations on no fewer than six occasions, and exhibited “fat tails”; (2) The time charter freight rates for a 10-year-old, 80?000 dwt vessel from 6 January 1989 to 26 December 2008: this series also exhibits skewness and kurtosis in a leptokurtic distribution; and (3) The Dry Cargo Time Charter Index from 1971 to 2004: this series diverged from the normal distribution four times. Next, we searched more recent data for short-term cycles using the V-statistic. One cycle was found to last 4 years (2005 to 2008), which is in accordance with theory. This cycle started on 29 July 2005 and ended when it reached the (lowest) level of $4000 on 1 December 2008. A new 4-year cycle started on 1 December 2008 and is forecast to last until the end of 2010. Short-term forecasting of the cycle using V-statistic is theoretically confirmed by the theory advanced by Hampton [1990, published in 1989, ‘Analysis and shipping cycles I and II’, Seatrade Journal, 19–23. Long and Short Shipping Cycles: The Rhythms and Psychology of Shipping Markets, Monograph, 2nd ed. (Cambridge: Cambridge Academy of Transport), March, p. 66].     

H ∞ control design to include nonlinearities. First report: saturation of the rudder

In designing a control system for large vessels, there are two kinds of nonlinearities which must be considered. One is the nonlinearity in equations of motion and the other is the saturation in control devices such as engine output or rudders. These nonlinearities can strongly affect the performance of the control system. A new method to deal with the nonlinearity of saturation has been proposed in this paper. The saturation is considered as a variation of gain in the system. A control system with gain variation can be designed by H _∞ control theory. As an example, a course-keeping control system for a course-unstable ship has been presented. The results show that the method proposed is effective.

Australian Beach Safety and the Politics of Shark Attacks

There are no simple government solutions when sharks bite people. These rare and sometimes fatal incidents are fraught with uncertainties and command a disproportionate amount of psychological space in the minds of the public, as well as a large degree of policy space and funding from many governments. Responses to mitigate shark bite incidents involve public policies that contend with the needs of public safety as well as the responsibility to protect endangered predators. Little study to date has been done examining the politics of shark attacks, yet these events are among the most geographically dispersed human–wildlife conflicts in the world. I examine the underlying concerns that drive this policy process by asking how problem definition framing by policy entrepreneurs affects government responses following shark bite incidents. Through a case study of shark bite incidents in Sydney, Australia in 1929, 1934, and 2009, I identify three competing problem definitions: behavioral, psychological, and conservation. The psychological definition, building confidence in the minds of the public, is shown to be the most successful. Building on previous research, I argue that policy entrepreneurship is a central feature in the strength of problem definitions. I conclude by suggesting lessons for the balanced coastal management of human–marine life conflicts including the selection of trusted spokespeople, prioritizing measures to relieve short-term public anxiety, reframing beach ecosystems as “the wild,” and connecting public safety education to personal behavior.     

A RANS-based technique for simulation of the flow near a rolling cylinder at the free surface

Accurate prediction of roll motion is very important in ship dynamics, particularly when the safety of the ship is in question. In this paper "COMET," a Reynolds averaged Navier–Stokes (RANS) solver, is used to simulate the flow in the vicinity of a rectangular cylinder rolling at the free surface and to demonstrate the potential of RANS-based techniques in complex flows with free surfaces. The method adopted is based on an unstructured collocated finite-volume technique, which uses a variation of the SIMPLE scheme for pressure correction. An advanced interface capturing technique known as high resolution interface capturing (HRIC) is used for tracking the free surface with reduced numerical diffusion. The results derived are compared with available numerical and experimental results, showing good agreement on added moment of inertia and damping coefficients, whilst accurately predicting other main features of the flow. However, further validation for other geometries and extension to 3-D hull forms are essential before applications to practical problems are realised.

Distribution of dinoflagellate cysts in surface sediments of the Mackenzie Shelf and Amundsen Gulf, Beaufort Sea (Canada)

In order to document long-term climate cycles and predict future climate trends for the Arctic, we need to look at the geological records to establish the link between historical and pre-historical sea-surface parameters. Dinoflagellate cysts (dinocysts) are used as proxy indicators of sea-surface parameters (temperature, salinity, sea-ice cover, primary productivity) jointly with transfer functions and a modern dinocyst reference database, to reconstruct the evolution of sea-surface conditions at decadal and millennial timescales. Here we present the surface distribution of recent dinocyst assemblages from 34 surface sediment samples collected on the Mackenzie Slope/Amundsen Gulf during the 2004 CASES (Canadian Arctic Shelf Exchange Study) cruise. Dinocyst concentrations in surface sediments are relatively high outside the Mackenzie plume area and increase gradually eastward toward Amundsen Gulf. The cysts of autotrophic dinoflagellates are dominant throughout the study area, while the maximum abundance of heterotrophic taxa is found within the Mackenzie plume. Hierarchical clustering analyses allowed defining two dinocyst assemblages. Assemblage I is located on the Mackenzie Slope and southern Amundsen Gulf, while Assemblage II is located within the Cape Bathurst Polynya area in northern Amundsen Gulf. Both assemblages are dominated by Operculodinium centrocarpum, but are distinguished on the basis of the relative abundance of Islandinium minutum, a taxon generally associated with sea ice. I. minutum is found in lower abundance in the Cape Bathurst Polynya.     

Large eddy simulations for quasi-2D turbulence in shallow flows: A comparison between different subgrid scale models

In this study, the performance of the horizontal large eddy simulation module, developed at the University of Leuven (HLES-KULeuven module) is assessed. A comparison between different subgrid scale models has been carried out. The study is concerned with the non-rotating and unstratified flows. The results of the simulation for an oscillatory backward facing (BFS) flow are presented in case of an expanding flume based on a one-length scale approach and a two-length scale approach. Three subgrid scale (SGS) models have been tested: Smagorinsky SGS model (Smagorinsky, J., (1963). General circulation experiments with the primitive equations, I. the basic experiments. Monthly Weather Review, 91(3), 99–164), Uittenbogaard SGS model (Uittenbogaard, R.E., and van Vossen, B., (2004). Subgrid-scale model for quasi-2D turbulence in shallow water. Shallow Flows. Jirka and Uijttewaal (Eds.), Taylor & Francis Group, London, ISBN 90 5809 700 5) and a proposed two-length scale approach. The first two models are considered to be a one-length scale models. A simulation without a subgrid scale model for the horizontal mixing has also been conducted. In all simulations, a quadratic friction model parameterizes the dissipation produced by the 3D-subdepth scale turbulence. The two-length scale concept uses a newly mixing length formulation for the quasi-2D turbulence and doesn't depend on the filter width in contrast to the one-length scale approach, in which the mixing length is function of the filter width. The outputs of the HLES-KULeuven module have been compared with the experimental data taken from Stelling, G.S., and Wang, L.X., (1984). Experiments and computations on separating flow in an expanding flume. Dept. Civil Engineering, Delft University of Technology, Report 2–84.). The two-length scale approach has been validated with experimental data from SERC Flood Channel Facility at HR Wallingford. In general, there is a qualitative agreement with the experimental data. It has also been found that the two-length scale approach produces more elongated and less isotropic vortex than the one-length scale models.     

Activities,resources and inter-organizational relationships: key factors in port competitiveness

In the last decade, the port economics literature has given great emphasis to the Supply Chain Management approach as the new paradigm for the definition of port competitiveness. SCM supports the development of partnerships between the actors of the supply chain and considers the integration of activities and resources along business processes as source of competitive advantage. Nevertheless, the application of SCM approach to the port is particularly compiex given the traditional hostile relationships between port actors. In the effort to overcome such complexity, some authors have considered ports as Logistics Service Providers and interpreted their role within supply chains through the integrative practices undertaken by Global Players–mainly Shipping Companies and Terminal Operators–in the supply of integrated logistics services. Even tough these actors are crucial for the port competitiveness, they determine a passive role of port in the new competitive scenario. The definition of a potential and pro-active role of port in the supply chains is the objective of this paper that presents, through a literature review on SCM and port competitiveness, a new framework for port competitiveness. According to this framework, that is based on the value constellation concept value is generated by joint effort of port actors in the satisfaction of clients' needs, through the exploitation of different I mterdependencies (serial, pooled and reciprocal) between supply chains. In this context, Port Authority has a I fundamental role in identifying those resources–the so called critical assets–that encourage the development of inter-organisational relationships between port actors in the value generation process.

An analysis of decision-making processes in multicultural maritime scenarios

With three research studies recently carried out the pros and cons of multicultural, multilingual crews have given a 'second' food for thought:

• The Seafarers' International Research Centre (SIRC): 'Transnational Seafarer Communities' and the research, 'Finding a balance: companies, seafarers and family life', linked to this [1]. The latter presented in Maritime Policy & Management, no. 1, January-March 2003.
• The Swedish National Maritime Museum (SNMM): Isolde av Singapore [2]. This research and sociological documentation will be reviewed in a later issue of Maritime Policy & Management.
• Horck, J., 'A culturally mixed student body; the WMU experience in fostering future decision makers' [3].

There is a growing conviction among seafarers and persons working in the land-based sector of the maritime industry (including ex-seafarers) that staff onboard and on shore should be prepared to work with crews and groups whose members come from different countries and cultures and speak different languages. The problem, though, is which culture will have to surrender and which will dominate? Will a third culture become the norm for common survival? Perhaps to understand oneself and be knowledgeable about others is a better way to avoid eventual conflicts.

There are nearly no research findings on how a programme should comprise the aims of facilitating comprehension and appreciation of influences, from differences in cultural backgrounds, on group performance and decisions.

This paper reports on the research carried out on students in the Shipping Management and the Maritime Education and Training courses at World Maritime University (WMU). How do post-graduate students holding unlimited certificates of competency, as well as holders of university degrees with experience in the maritime industry and maritime administration, come to a consensus decision?

The findings in this research are discussed in balance with the results from both the SIRC and the SNMM research which is interesting because the results, in some significant issues, are not the same.

A phenomenographic approach has been used to find out that a multicultural group is not free from working problems. Can cultural differences, perhaps, be developed from an assumed hindrance into a catalyst for stimulating national appreciation and cooperation? Perhaps the opposite is true; it might be a bottleneck for improvements in safety as formulated in the STCW95 and the ISM Code.

Personal history I began my career with Mitsui O.S.K. Lines (MOL) upon graduation from Kyoto University in 1967. During my 38-year career at the company, I have been involved in a broadrange of maritime activities, and have witnessed dramaticchanges in the industry as it has sought to meet the changingneeds of societies and the globalization of economies. Keyevents in my career include a posting to Mitsui O.S.K. Lines'San Francisco Representative Office from 1975 to 1979;becoming a staff officer of the Planning Division in 1987,followed by a promotion to Deputy General Manager of theDivision in 1988; appointment as General Manager of Europeand Oceania Division in 1993; being elected to a directorshipin 1996; promotion to Managing Director in 1998, SeniorManaging Director in 2000, Deputy President in 2003, andfinally President in 2004. For me, the shipping industry isboth a business and a passion. I am extremely excited aboutthe changes and challenges that lie ahead for the industry aswe begin the 21st Century, and consider myself to be in amost enviable position leading Mitsui O.S.K. Lines, acompany at the vanguard of shipping developments, in theseexhilarating times.     

Parameterisation of clastic sediments including benthic structures

The sediment transport processes in the south-western Baltic Sea are predicted by means of a numerical model in the project DYNAS. There are two sediment parameters that influence the results of modelling remarkably: critical shear stress velocity and bottom roughness. This paper presents the way how to parameterise these factors and extrapolate them into the investigation area. The critical shear stress velocity is parameterised basing on grain size data, combining approximations after Hjulström [Hjulström, F., 1935: Studies in the morphological activity of rivers as illustrated by the river Fyris. Geological Institution of University of Uppsala: Bulletin (25): 221–528.], Shields [Shields, A., 1936: Anwendung der Ähnlichkeits-Mechanik und der Turbulenzforschung auf die Geschiebebewegung. Mitteilungen der Preussischen Versuchsanstalt für Wasserbau und Schiffahrt (26): 26 pp.] and Bohling [Bohling, B., 2003: Untersuchungen zur Mobilität natürlicher und anthropogener Sedimente in der Mecklenburger Bucht. unpublished doctoral thesis, Mathematisch-Naturwissenschaftliche Fakultät, Ernst-Moritz-Arndt-Universität Greifswald/Germany, 156 pp.]. The roughness length, in the case of absence of macro zoo-benthos and their structures, is parameterised basing on grain size too employing Soulsby [Soulsby, R.L., 1997: Dynamics of Marine Sands: a Manual for Practical Applications. London, Thomas Telford Publications. 249 pp.], Nielsen [Nielsen, P., 1983: Analytical determination of nearshore wave height variation due to refraction shoaling and friction. Coastal Engineering 7, 233–251.] and Yalin [Yalin, M.S., 1977: Mechanics of Sediment Transport. Pergamon Press, New York. 298 pp.]. No equivalent simple parameterisations for biologically caused bed roughness exist. Here, findings of Friedrichs [Friedrichs, M., 2004: Flow-induced effects of macro zoo-benthic structures on the near-bed sediment transport. Dissertation, Universität Rostock, 80 S.] and estimations by the DYNAS biologists group were combined in order to derive roughness lengths from abundance measurements of four previously selected key species which represent the originators of the dominating benthic structures at the sea floor in the south-western Baltic Sea. Critical shear stress velocity and bed roughness are known at few sample sites only. They were extrapolated into the larger investigation area using a proxy-target concept. The mean near bottom milieu (bathymetry, median grain size, salinity, oxygen) which was derived using results from numerical modelling serves as the proxy. Since the milieu parameters are measured at the sampling sites for which the target parameters have been determined, a combined hierarchical and supervised classification was employed to transfer the local knowledge into the unknown investigation area.     

Ocean energy—an update

The oceans of the world, which comprise 71% of the earth's surface, provide a vast resource of renewable energy which has only been used in limited quantities. The feasibility of the extraction of energy from the ocean has been discussed and deemed possible, but with very few successful applications. However, as the world energy and economic situation changes, many countries are initiating R&D programmes to use the ocean waves, tides, currents, and temperature differentials to produce electricity. The transmission and utilization of this oceanderived electricity requires the integration of an ocean facility into an existing land-based electric power transmission grid. Extensive use of this energy source is still years in the future; however, prototype systems have been and are being developed so that this limitless supply can be successfully tapped.     

Planning framework of analytical approaches applied to Zairean transportation

The purpose of the article is to provide an analytical planning framework which includes decision makers, organizations imposing operational and institutional constraints, direct customers and indirect beneficiaries. All these actors have differ-ent, only partially overlapping, interests; this increases the complexity of capital budgeting and imposes limitations on decision-making framework has important implica-tions for project selection, charging and depreciation policies. Although the illus-trations are limited to transport planning, the framework can be easily applied to any sector or country. For example, the English engineering students applied the framework to 18 industries in the U.K.: Auto-diesels, Bass, British Airways, British Gas, British Oxygen, British Petroleum, British Rail, British Steel, British Telecom, East Midland Electricity, Guinness, Imperial Chemical Industries (ICI), Inter-national Computers Limited (ICL), Marks & Spencer, Mercury Communications, National Westminster Bank, Rover and Thames Television (see A. Kelvin, 1993, Increasing student participation in the learning process. Higher Education, 26(4), December, 449-470).
