The port, a point of entry : the design of a new cruise liner terminal at the point, for Durban.

Bexiga, Ricardo. January 2008 (has links)
This research examines the complex factors that influence the design of a new cruise liner terminal for Durban. Secondary and primary data collection methods will be used in the research. Secondary data collection forms the majority of the information gathered. This method will focus on precedent and case studies from which conclusions will be drawn and a design brief for the cruise terminal derived. Cruise liners typically spend periods of less than a week in port, during which time passengers will visit local tourist attractions. Durban's cruise season lasts from mid-November till mid-April. The local cruise industry has seen a steady increase in passenger numbers over the years. This has seen the MSC Melody cruise ship being procured to meet the demands of the industry. As a consequence of this increase the current cruise liner terminal, the N-Shed, has been placed under increasing pressure to provide a world class facility and service experience, expectations which it is ill equipped to deliver. Through this study key aspects, specific to the cruise liner terminal design, are investigated. These include passenger movement optimisation, response to local conditions, form development, waterfront regeneration and the concept of the terminal as a gateway to the city of Durban. In developing the architecture of the cruise terminal, the understanding of these factors is vital if the designer is to make a meaningful contribution to society though his building . With the cruise liner terminal being a unique building typology, in the context of Durban, an opportunity arises to reconnect the city with its harbour edge. / Thesis (M.A.)-University of KwaZulu-Natal, 2008.

The use of the toxicity identification and evaluation (TIE) protocol in the Port of Durban, South Africa.

Parsons, Gary Angus. January 2011 (has links)
The Port of Durban, with its close proximity to industrial, urban and agricultural activities, receives a number of chemical pollutants that settle out and accumulate in sediments. Chemical analysis of these sediments has indicated elevated levels of chemicals that, according to sediment quality guidelines, might cause adverse biological effects. However, elevated concentrations alone do not necessarily imply that chemicals are present in bioavailable concentrations high enough to be harmful to organisms that come into contact with them. Thus, chemical tests alone cannot provide an accurate indication of the potential adverse biological effects of these chemicals. In this regard, toxicity tests of sediment porewaters have been developed using sea urchin gametes to assist in determining the bioavailability of chemicals present in porewaters. Further, procedures such as Toxicity Identification and Evaluation (TIE), which involves the manipulation and/or treatment of toxic porewater, have also been developed to assist in the isolation and identification of chemicals causing porewater toxicity. In this research, on a number of sampling occasions between July 2007 and July 2009, three replicate sediment samples were extracted from a site in the Port of Durban known to contain sediment with potentially toxic porewater. Results of initial toxicity tests, using the sea urchin fertilisation test indicated the presence of toxic porewater although, in some instances, porewater toxicity was highly variable between replicate samples. However, results from TIE procedures performed to reduce potentially toxic concentrations of metals, ammonia and organic compounds did not resolve the primary cause of porewater toxicity. Further research indicated that chemicals including hydrogen sulphide, which can occur naturally in organically enriched sediments, may have been confounding factors that masked the potential toxicity of other chemicals present in the sediment samples. Consequently, a sampling strategy and modified TIE procedure have been recommended. The sampling strategy has been designed to assist with detecting and understanding any sample variability that may occur. The modified TIE procedure, which suggests initial procedures to determine and reduce/remove the possible confounding effects of potential naturally occurring compounds such as hydrogen sulphide from the porewater, could be used in future to understand and evaluate the quality of contaminated sediments from similar environments. / Thesis (M.Sc.)-University of KwaZulu-Natal, Westville, 2011.

Bunker callers to the port of Durban : a research into how to gain back this lost business.

Gardner, Rob. January 2006 (has links)
The dissertation sets out to identify the reasoning behind why there has been a decline in bunker callers to the port of Durban at a time when there has been an increase in shipping activity and other ports around the world have experienced rapid growth in their bunker markets. It was first necessary to establish that there has been a fall off, what the economic impact of the fall off was and then to analyse the current operational procedure and the strengths and weaknesses of the port. The ports of Singapore and Gibraltar are looked at as they are two ports where bunkering has grown over the period Durban has seen a decline. The SWOT analysis of Durban takes into account the survey that was conducted by IBIA to ascertain what were perceived to be the main factors behind South African ports losing bunker business The type of ship that calls at Durban for bunkering and what is the most common voyage route are identified. It was found to be a handy size ship with the last port of call being a South American port. The cost for the voyage and the port call at Durban are calculated to work out the maximum time the ship should be at Durban from arriving outside to once again sailing. It is found to be twelve hours. The relationships of the parties to the bunker operation are analysed to see where it would be possible to introduce efficiencies to the supply chain and how to reduce the overall port stay to under twelve hours. Over an above this the port costs are reviewed as there are areas where discounting could be introduced to once more encourage owners to call A major stumbling block to the whole process is the unreliability of supply with the port being unable to provide bunkers 11% of the time. The need to address the stock management problems experienced by the majors is vital to the success of promoting Durban as a bunker port and ways of achieving this are proposed. / Thesis (MBA)-University of KwaZulu-Natal, 2006.
