Cargo Hold Capacity Calculations Part 2: Draft & Load Line Restrictions with Density Corrections

This video shows how to calculate the amount of cargo that can be loaded in each ship's cargo hold. It involves manual calculations about the percentage capacity of each hold.
It covers draft restrictions and the ship is sailing from summer to winter zone with density corrections.

I have one question. If no restriction draft in discharging port, so with max draft loaded in seawater no need to do density correction for discha port, we can take in account dwa, that’s correct?

[@nauticalacademy001]

Great question! You are right. If there is no draft restriction at the discharging port and the ship is loaded to its maximum permissible draft in seawater, you don’t need to apply a density correction for the discharging port. However, you must also account for the change in draft when transitioning from salt water to dock water, considering the ship's UKC. Calculating the Dock Water Allowance (DWA) is essential to ensure compliance with the minimum UKC requirements as per company policy.

@ Thank you sir for answer. Appreciate it.

Nice vlog how about summer loading port about 7days she pass to winter in certain latitude and longitude position that when she pass she will be in winter tks

[@nauticalacademy001]

Thanks for watching! Great question-to maximize the loading capacity from the loading port (summer zone) to winter zone, coordinate with Chief Engineer to confirm ROBs of FO, DO & LO upon arrival in the winter zone . Share details of the voyage plan, especially the distance from the loading port to the winter zone, then calculate the loadable cargo considering other consumables onboard using the loading-back method. If the vessel carry more cargo while sailing within the winter zone following the permissible winter draft, be sure that upon arrival at the discharge port draft requirements are complied, recalculate consumables from the winter zone up to arrival to ensure compliance with draft restrictions in the discharging port. This approach helps you maximize the loading capacity of the ship, maintain safe and compliant drafts requirements throughout the voyage. Thanks

How about if the density in loading is less 1.018 and the discharging port is 1.025 so the density correction is added am i correct to get the actual cargo to load

This explanation why no multiple SF like part 1 for each hold

[@nauticalacademy001]

In this video, it has only one type/grade of cargo (coal), so only one SF, the same as part 1. In part 1, it has only one SF because the cargo has the same type/grade. Kindly review part 1, thank you.

@nauticalacademy001 Thank you Sir,

[@ernieaguilar3997]

How about there are 3 grades of cargo different SF can you make a vlog tks

@@ernieaguilar3997 I will try if time permits. Thank you.
