5 TASK III - PORT FACILITIES REQUIREMENTS 93. The analysed short-, medium- and long-term cargo throughputs through Namibian ports have to be translated into port, berth and quay facility requirements, categories and dimensions as well as realistic ship movements for different commodities. These projections for different cargo commodities are pictured in the following tables (tables 27, 28, 29, 30 and 31).

94. At present the entire pelagic fish catch is landed or transhipped at W.B. It can be concluded that, modernisation apart, the existing fishing port at W.B. could handle the entire purse-seiner catch at MSY after full recovery of the pilchard and anchovy stocks. The present W.B. frontage is about 1.800 m which could be optimally compressed to 1.000 m frontage elsewhere. The demand analysis suggests that about 25% of the total pilchard and anchovy landings could be more economically provided for at a North Coast fishing port with required landing jetties and a frontage of 300-400 m. See tables 32 and 33.

95. The mid-water trawler fleet presently responsible for landing large quantities of horse mackerel as frozen blocks (primarily for transhipment) and fish meal (for export) will require a future berth length of approximately 450 m with a depth of water alongside of 9 m. This pre-supposes that all frozen fish scheduled for transhipment will in future first be off-loaded to shore. Indications are that the sources of such transhipments of frozen fish are distributed in the ratio 50%:30%:20% between the northern, central and southern fishing grounds. See tables 34 and 35.

96. The various growth scenarios anticipated for
the future white fish landings are expected to affect the trawler fleet size in proportion
to the expected increase in catch volume from 1995 onwards. Table 36 gives the required
berth length for white fish trawler landings. The demand analysis revealed that 20-25% of
the total berth lengths could be provided at a North Coast Port in place of W.B. See also
table 37.

97. Table 38 gives for the expected growth scenario the required berth lengths for smaller fishing vessels where also 25-30% could be economically justifiably used at a North Coast Port. See also table 39. Table 40 gives the summarised "Exports of Fish by Sea".

98. Table 40 gives the required berth lengths for the handling of general cargo commodities. These commodities are expected to remain via coasters and general ocean-going cargo carriers of the 5.000 to 20.000 GRT class requiring a depth of water less than 10 m. The demand analysis for expected growth showed that 2 berths will be sufficient to handle the increased cargo throughput, but that a 3rd berth might be essential to avoid congestions in case of simultaneous arrivals. The additional berths under the rapid growth scenario are required for cement exports. The sea area associated with a single general cargo berth (average: 180 m) is typically 50.000 to 60.000 m2 and the land area 4.000 to 15.000 m2. Every second general cargo berth should be backed up by a storage shed of approximately 3.500 m2. Each berth should also be serviced by 2 wharf cranes (5 - 15 t) and have railway line access along the quay side.

99. Table 41 gives the containerised cargo facilities. The table indicates that, even in the longer-term, a single, dedicated container berth with one container crane will suffice to handle the increased containerised cargo. The sea area associated with the single container berth (of total 180 m length) is typically 50.000 to 60.000 m2 to accommodate a throughput of up to 100.000 containers per year. Both the quay side and stacking areas should be serviced by rail access.

100. Table 42 gives the expected dry bulk cargo facilities. Handling of the sea transportation of imported bulk commodities is expected to remain via ordinary coasters of the 5.000 to 10.000 GRT class while bulk salt export will remain via special bulk carrier requiring a depth a water depth of less than 10 m. In the near future these vessels are expected to visit the port at an average rate of one per week. Of these ships, one third would be dedicated to salt exports and one third to mineral/ore exports. The table furthermore indicates that 2 berths will suffice. The sea area associated with a single berth (of total 180 m length) is typically 60.000 m2 and the land area 5.000 m2.

101. Table 43 gives the expected liquid cargo facilities. The sea transportation is expected to remain via coaster tanker of 20.000 GRT class requiring a depth of water of less than 10 m. The table indicates that a single (dedicated) liquid cargo berth/terminal will be sufficient to handle the increased fuel throughput. The sea area associated with such single berth/terminal is typically 250.000 m2. Storage capacity, in the form of tanks, should require a ground area of not more than 10.000 m2.

102. As far as facilities for the Off-shore Oil Industry are concerned, for the two first exploration phases to the year 2000 no special port facilities are required. After the year 2000 exploration is expected to continue with five floaters in operation. The required port facilities for the peak of the third exploration phase can be quantified in table 44:

103. Major port developments can, however, be expected if sufficient quantities of oil/gas are being exploited off-shore to justify a local refinery. For exporting refinery products it is expected that a loading jetty or a single buoy mooring (SBM) to accommodate one 70.000 GRT tanker would be needed by the year 2010.
104. Other port facilities will be needed for the mooring of 2 fisheries inspection vessels, 1 survey ship (requiring berth lengths of 3 x 100 m) and 2 coast guard vessels (requiring berth lengths of 2 x 70 m). Equipment storage as well as office space will be required and an area for confiscated ships as well as fishing boats awaiting the next season.
