Normally, percentages of days at sea are best rounded up to whole days for the sake of simplicity of calculation and to allow for any unforseen delays. But where short voyages are involved this is not realistic. Thus, for the 475 miles between Toasmasina and Port Louis (Mauritius) 1½ days should be allowed (475/312 = 1.522) although this percentage can be disposed of in the final voyage days analysis by allowing a compensating 2½ days to load in Mauritius. Mauritius to the Suez Canal is 3650 miles which, divided by 312 miles per day, equates to approximately 12 days. You are told to allow 2 days for the canal transit and a canal bunker consumption of 7 tonnes each of fuel and diesel oil, so these details can be entered. The final leg of 3200 miles from the Suez Canal to London should take about 10 steaming days. The one remaining entry for the ‘itinerary’ section is that of port time in London but, since we are to work on a daily discharge rate in London (for which we must “allow full laytime”) we must first calculate the quantity of cargo on board. To do that we should consider load-line zones and any port limitations en route. The ship’s draft fully laden is still within the limits of the Suez Canal and there is adequate depth of water at both loading and discharging ports. Consequently there are no restricting factors affecting the quantity of cargo to be loaded apart from those of the ship itself, its cubic capacity and deadweight. Bulk sugar stows around 1.13 to 1.22 cubic metres per tonne (40 to 43 cu.ft). Allowing for an increase to this figure for loss of trimming spaces, as a result of tweendeck overhangs, of an extra 10 percent as compared with a bulkcarrier, the cubic space available should still be more than adequate. 21295 cubic metres divided by 1.34 (1.22 + 10%) = 15900 tonnes approximately.
