SECTION 1 INTRODUCTION AND EXECUTIVE SUMMARY
This provides a comprehensive summary and conclusions for the study.
SECTION 2 THE FLEET
The development of the world fleet of ocean-going, continuous self-unloading bulk carriers is considered in this Section. Recent additions and losses are reviewed, and the development of "hybrid" crane-plus-belt self-unloaders is analysed.
The fleet and its development are analysed by:
The Section concludes with a separate consideration of the development of the self-unloading cement carrier fleet, which is also analysed in terms of its size categories and flag registration.
SECTION 3 USES AND TYPES OF SELF-UNLOADING VESSELS
A description of the evolution of continuously self-unloading vessels is followed by a comprehensive analysis of self-unloader technology, including top-reclaiming and gravity based types, hybrids and cement carriers.
The relative suitability of different systems for different types of cargo and trading environments is considered; and the special characteristics of cement self-unloaders are examined. The environmental impact and operational experience of different systems are also evaluated, and typical discharge rates for different kinds of self-unloader are compared.
SECTION 4 OPERATORS AND TRADES
This Section provides a comprehensive collection of profiles of self-unloading bulk carrier operators, covering their fleet characteristics and deployment (by region and type of cargo), the types and speed of self-unloading equipment used in their vessels, as well as the yard of construction or conversion.
The Section also provides matrices of operators and cargoes, and regions of deployment, summarising the global network of trades and operators.
SECTION 5 GEARED BULK CARRIERS AND FREIGHT BATES
The trade-off between the higher capital costs of self-unloaders and the lower productivity and environmental drawbacks of conventionally geared bulk carriers is a major factor in the comparative shipping economics between these two kinds of vessels.
This Section reviews the development of the world fleet of geared vessels, and analyses the fleet profile in terms of its size sectors and age.
Developments in the bulk carrier freight market, including both spot-charter and time-charter rates, are analysed, and the implications for the self-unloading bulk carrier market highlighted.
SECTION 6 SHIPPING AND PORT COST COMPARISONS
This Section compares the costs of operating self-unloading bulk carriers, hybrid and conventionally geared and gearless carriers.
It includes detailed discussion of the capital and operating costs for different sizes and types of carrier. Bunker consumption and the development of bunker fuel costs are also considered.
The potential reductions in port costs associated with investing in shipboard unloading gear rather than shore-based equipment are also examined in detail.
SECTION 7 COMPARATIVE VESSEL COSTS AND CASE STUDIES
This Section calculates and compares daily voyage costs per tonne of cargo for the different types and sizes of vessel, over different representative haul lengths.
It then presents a series of notional ease studies of the economics of particular trades typically operated by self-unloadcrs or which represent potentially fruitful opportunities for their use. These range over different commodities, haul lengths and vessel sizes, and assess the competitiveness and viability of some typical self-unloader trades based on current costs and freight rates.
SECTION 8 FUTURE DEMAND FOR SELF-UNLOADERS
The successful utilisation of self-unloaders is a result of combining the identification of a transport opportunity with an entrepreneurial and effective use of technology. Hence, particular trade and cargo considerations are of primary importance in developing market prospects. The study considers the opportunities for further development of self-unloaders by identifying trade conditions where these vessels can be seen to have the most potential. This analysis is based upon OSC’s detailed knowledge of world bulk trades, port development status and shipping economics.
The general conclusion is that considerable further opportunities can be identified. The study also considers the fleet development which would be required to maintain the self-unloader share of bulk carrier markets.
The appendices list the 2002 ocean-going self-unloading bulk carrier fleet by deadweight capacity, year of construction or conversion, and region of deployment. Each vessel entry includes details of deadweight, year of construction (and conversion where applicable), yard and country of construction (and conversion where applicable), type of unloading gear, rated discharge speed of unloading gear, cargoes and region of deployment.
The self-unloading cement carrying fleet is also detailed.
