ii) Generate an ocean container loading plan for the whole shipment. Estimate the containers required: 456 in (38 ft) x 42 in x 36 in x 8 = 5,515,776 in 3 ÷ 61,023.744 = 90.39 m 3 This is within the capacity of 4 x 20-ft standard containers OR 2 x 40-ft standard containers. Since the 20-ft standard containers are NOT long enough to hold the 38-ft (456-in) crane boom, we need to use 2 x 40-ft standard containers. Looking at the length and weight of the sections of crane booms, it is not feasible to load these items with a forklift through the door of a 40-ft standard container. Therefore, we need to look at alternatives - a 40-ft open-top (the top is removable) or a 40-ft flat-rack container. Either one would do, but looking at the dimensions and weights, the 40-ft flat-rack container may be better. This would allow the persons loading the sections of crane booms into the container an opportunity to tie-down and block and brace the cargo, something that may not be possible inside a 40-ft open-top container because of the confined space. With the size and weight of this particular cargo, we don’t want any of it shifting during transport. THIS WOULD BE DISASTROUS! 462 x 90 x 78 = 1.1 x 2.1 x 2.2 456 42 36 = 1 x 2 x 2 = 4 sections of crane booms per 40-ft flat rack container (2 x 40-ft flat-rack containers required)

Answers Ocean Freight Page | 170 2017 Let’s verify the weight : 2,500 kg x 4 sections = 10,000 kg, which is well within the maximum payload capacity of a 40-ft flat rack container (25,000 kg). Now we have confirmed that the dimensions and weights for this shipment are within the capacities of 2 x 40-ft flat-rack containers. 40-ft Flat-Rack Container - TOP VIEW (2 x 40-ft flat-rack containers required. 2 crane booms x 2 layers high = 4 crane booms per 40-ft flat-rack container.)

Answers Ocean Freight Page | 171 2017 2. A shipment of printing presses, and a shipment of stuffed toy animals need to be transported by ocean container. Details: x 30 crates of printing presses. The dimensions of each crate are 86 in x 47 in x 58 in, the weight of each crate is 2,200 kg. Keep upright. x 171 cartons of stuffed toy animals. The dimensions of each carton are 24 in x 24 in x 24 in, the weight of each carton is 3 kg. Fragile, top-load only (load these items on the top of heavier items). i) How many and what type(s) of ocean containers are required to move this shipment most economically? ii) Generate an ocean container loading plan for the whole shipment. Estimate the containers required: (86 in x 47 in x 58 in x 30 crates) + (24 in x 24 in x 24 in x 171 cartons) = 7,033,080 in 3 + 2,363,904 in 3 = 9,396,984 in 3 ÷ 61,023.744 = 153.9889 = 153.99 m 3 The total shipment volume EXCEEDS the capacity of 2 x 40-ft plus 1 x 20-ft standard containers (50 m 3 + 50 m 3 + 28 m 3 = 128 m 3 ). Since most of the cargo is palletized, we need to re-think what type of containers to use.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
