    Fun fact : The spaces between the hull and tank are serviceable with crawl passages. You can also enter right under the tank and crawl into no man's land to swap a pt100 sensor. Got to do it once and it was an experience to be had as a service Engineer.

    As mentioned elsewhere in the comments, apart from a few minor details this is a nicely put together and informative video that gives anyone unfamiliar with tankships a good basic understanding of the principal. It's nicely presented and thought out without being overly long or technical. I'll be saving this, along with checking out some other videos from 3D.

    Thanks for this video. In 1970 I was a radio officer on a VLCC. I never knew much about the function of the ship as I was only concerned with safety of life messages and and commercial messages. One time in the Indian Ocean we had to go over a Tsunami wave at an angle of 45 degrees. The 300 metre deck rose up into the air in front of the ship and then moved down the opposite side.

    I crewed a VLCC in the late sixties and the seventies…. Shell M boats, so named because their names all began with the letter M. Interesting fact it was possible to see the hull flexing up and down in heavy seas. A bit disconcerting when one first sees it…Crew comfort was pretty good for the period. With self contained cabins that included a bathroom/toilet etc. great days of my youth…

    @polarshift6551 Рік тому

    Good to see a easy to understand view of a tanker. I don't often see breakdowns of tanker design.
    There is one correction you might make. From the manifold there are drop lines to the bottom lines so there is no need to route through the pumps. The bottom lines fill the tanks by using valves to open and close the required tanks with the segragations as you describe. This way the vessel uses the energy of the shore pumps to fill its tanks. Loading through the pumps is possible but it causes unnecessary wear on the cargo pumps and is slower loading than using the drop lines. Normally only used in emergency if there is an issue with bottom valves.

  • @robertlevine2152
    @robertlevine2152 Рік тому +19

    The ship's cargo pumps are not used in loading. The pumps are used for discharging cargo. There are drop lines that run from the cargo manifold to the cargo lines at the bottom of the cargo tanks through which the cargo is being loaded. These same lines at the bottom of the tanks are used as suction lines when pumping the cargo off.
    The cranes at the manifold are there primarily for the handling of cargo hoses. The cranes are sized based on the handling of cargo hoses. The handling of ship stores is a secondary function. There are cranes near the accommodation block aft, whose primary function is the handling of stores.

    • @robertlevine2152
      @robertlevine2152 Рік тому +2

      @HonkForThatcher I agree. Larger ships are also fitted with Cargo Control rooms where cargo loading and discharge, ballast loading and discharge, inert gas, and the ship's loading computer are located.
      With that said, I know of ships that had their Engine and Cargo Control Room equipment on the bridge. The last tankers I was involved with had computers that were linked through a common system. With the correct passcodes, you could log into any terminal for control.

    Shown is a VLCC type, the only type of crude vessel sailing with cargo tanks in the centre as well as the wing tanks. Some modifications - bridge wings are missing, you need to be able to see the side of the ship from the bridge for mooring. The pipe rack has many less pipes forward of the centre manifold area. When loading the cargo passes from the manifold down the drop line to the bottom line. Oil is not loaded via the pump-room as shown. Hope that helps - have a look at my VLCC "Solana".

  • @32voodoo

    COW or Crude Oil Washing is the most dangerous part of the process of moving crude oil. Using some of the cargo, the oil is heated to a suitable temp and sprayed with fixed nozzles to clean the residue from the tanks. If you think this creates a explosive atmosphere you would be correct, also, the spray of hot crude oil causes lighting to occur in the tanks while cleaning, so there is an ignition source. They used to figure that there was insufficient oxygen in the tank, displaced by the explosive and flammable gases cause by the crude oil washing, or water washing used previously, to pose a danger. Except, tankers were going missing at sea, presumably while cleaning tanks on the way to pick up an new load.
    So, the exhaust gases from the stack are now captured, washed and pumped into the tanks to create an Inert Gas System to prevent tankers from blowing up. COW and IGS are two important systems used in modern tankers that reduced pollution enormously. The atmosphere of the tanks is closely monitored, because you have a explosive atmosphere, there is an ignition source, and if for any reason, the tanks are not filled with inert gas. Boom. My experience was, good people, good food, but long hours, dangerous conditions and poor pay.

    One thing I was going to add being the current state of the world's energy markets between a bigger oil tanker and a smaller oil tanker is how Russia is getting around it's oils restrictions by taking its smaller tankers going out into the Mediterranean and just filling up differently flagged bigger tankers and then selling the oil as if it came from somewhere else
    But that's only a small aspect of the big tanker versus smaller tanker relationship
