  1. How many days will the ship take to steam from A to X?<\/span><\/li>\n
  2. How much fuel will she use on that part of the voyage?<\/span><\/li>\n
  3. Assume she needs enough fuel to reach X plus five extra days\u2019 steaming.<\/span><\/li>\n<\/ol>\n

    3.1\u00a0 \u00a0How much fuel should she have on board when sailing from Port A?<\/span><\/p>\n

    3.2\u00a0 \u00a0How many tons of extra cargo can she carry if she only has on board the required amount for the voyage A to X plus five extra days?<\/span><\/p>\n

    3.3\u00a0 \u00a0How much will she earn from the extra cargo carried?<\/span><\/p>\n

    3.4\u00a0 \u00a0How much extra will it cost in terms of fuel and operational costs to call at X?<\/span><\/p>\n

      \n
    1. How many days will the ship take to steam from X to B?<\/span><\/li>\n
    2. How much fuel will she use on that part of the voyage?<\/span><\/li>\n
    3. Assume she takes only enough fuel at X to steam to Port B plus five days\u2019 extra.<\/span><\/li>\n<\/ol>\n

      6.1\u00a0 \u00a0How many tons of fuel did she have left on reaching Port X?<\/span><\/p>\n

      6.2\u00a0 \u00a0How many tons of fuel will she need to take at Port X?<\/span><\/p>\n

      6.3\u00a0 \u00a0How much will that fuel cost?<\/span><\/p>\n

        \n
      1. Calculate the costs (operational and fuel) of a voyage from Port A to Port B without calling at Port X.<\/span><\/li>\n
      2. How much will the ship earn for the voyage?<\/span><\/li>\n
      3. Calculate the costs (operational and fuel) of a voyage from Port A to Port B but calling to bunker at Port X.<\/span><\/li>\n
      4. Will it be beneficial for the ship to call at X or should she omit the call at X?<\/span><\/li>\n
      5. Which routing will give the ship more profit for the voyage?<\/span><\/li>\n<\/ol>\n

        Section\u00a0B<\/span><\/h4>\n

        About 45 ships pass the Cape each day, yet only a few call to work cargo or to bunker.<\/span><\/p>\n

          \n
        1. Why is it important to encourage these passing ships to bunker in South African ports?<\/span><\/li>\n
        2. What can be done to encourage them to call at South African ports?<\/span><\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
