  what is the difference between FWA and DWA?

• 
  @nauticalacademy00124 күн бұрын

  FWA is the number of millimeters by which the mean draft changes when a ship passes from saltwater to freshwater, or vice versa, while floating at the loaded draft. This is typically measured when a ship is moving from seawater to freshwater, such as when entering a river or a lake. Dock Water Allowance (DWA): DWA is the number of millimeters by which the mean draft changes when a ship passes from saltwater to dock water, or vice versa, when the ship is loaded to the Summer displacement. Dock water is a type of water with a density between that of seawater and freshwater. DWA is typically measured when a ship is moving from seawater to dock water, or vice versa, while in a dock or a shipyard. FWA is the change in draft when a ship sails from seawater to freshwater or vice versa, while DWA is the change in draft when a ship sails from seawater to dock water or vice versa or from dock water to another dock water with different water densities. The key difference is the type of water involved, with FWA involving a transition between seawater and freshwater or vice versa, and DWA involving a transition between seawater and dock water or vice versa.

  @@nauticalacademy001 so we can calculate the change of draft by FWA value and TPC value with the given formula DWA= change in draft= displacement * change in density/ 0,025

  Hi, at the last example, ive notice that you calculate as if the ship is going from higher R.density to Lower R.density. But as the example ship is depart from 1.007 to 1.018. Draft should rise then right? It should be decrease in draft. Kindly clarify. By the way great animation and lessons. Thank you🙂

• 
  @nauticalacademy001Ай бұрын

  Hi! Thank you for your comment. In my last example, in the final step, I subtracted the dock water allowance from the departure draft to find the arrival draft, since the ship sails from a lower R. density (1.007) to a higher R. density (1.018). The effect on the ship upon reaching higher density, she will rise, and as a result, there will be a decrease in the ship’s draft. That is why DWA should be subtracted from the dep. draft to find the arrival draft as shown in my final step which is also stated in your comment, a decrease in the arrival draft. Maybe you are confused when I take the difference of the departure and arrival relative density because, in my solutions, I have shown (1.018 - 1.007) which is the arrival R.D 1.018 minus the dep. R.D 1.007. What I did is subtract the lesser from the greater R.D. so that I would have a positive DWA, but this procedure does not affect the ship’s draft yet. As you mentioned in your comment the ship will rise in this problem, and there should be a decrease in the ship’s draft “You are right”. That is why in my final step, I have subtracted the DWA from the dep. draft to determine the arrival draft because the effect is a decrease in draft. Now you can also follow this format (1.007 - 1.018) which is departure R.D 1.007 minus arrival R.D 1.018, you will have a negative DWA. A negative DWA should be subtracted from the departure draft, and the result will be a decrease in the arrival draft as shown in my final step. Thank you very much👨

•

  There are several formulas to find the scope of the anchor, others use the numerical ratio to find the number of anchor shackles to be dropped depending on the weather conditions. You can use any method that you prefer as long as you comply with the company's Quality Management System (QMS) Manual.

  Subtracting 2H to ZD 5 is can not be, you need to borrow 1day on the date which is equivalent to 24 hours, then add that 24 hours to 02H, so you have now 26H minus the ZD 5, the answer is 21H.

  Good day.When we calculate safety depth which tide we minus MLW or MHW?

• 
  @nauticalacademy0013 ай бұрын

  Typically, the safety contour is established by considering the lowest astronomical tide (LAT) or mean low water springs (MLWS). Mean Low Water Springs (MLWS) represents the average lowest water level that occurs during spring tides over an extended period. Spring tides occur when the sun and moon are aligned, causing higher high tides and lower low tides. Using MLWS as a reference provides a conservative approach to ensure that the charted depths are sufficient for navigation under most tidal conditions. So, in the context of determining the safety contour, you would subtract the anticipated tidal range from the charted depths based on MLWS or a similar reference level to ensure safe navigation during varying tidal conditions.

  Which draft will be change, if there's correction? F, M or aft?

• 
  @nauticalacademy0014 ай бұрын

  When a ship moves from water of higher density to lower density, or vice versa, a phenomenon known as "sinkage" or "rise" affects the ship's draft. This is often called "density effect" or "density correction." The change in water density influences the ship's buoyancy, causing the entire vessel to "sink or rise" by a few centimeters in the water. This will cause a change in the ship's draft both forward and aft including the mean draft. Thank you for the comment.

  @georgen97554 ай бұрын

  Sorry What does that GM mean ??

• 
  @nauticalacademy0014 ай бұрын

  The term "GM" in the context of a ship refers to the metacentric height, a critical parameter for assessing the stability of a floating vessel. The metacentric height is denoted by the symbol "GM." GM is the vertical distance between the center of gravity (G) of a ship and its metacenter (M) when the vessel is tilted or heeled due to an external force (such as a wave or wind). A positive GM (GM > 0) indicates a stable initial equilibrium meaning that the ship tends to return to an upright position after being tilted. A negative GM (GM < 0) indicates an unstable initial equilibrium meaning that the ship tends to continue tilting and may be prone to capsizing. Thank you for the comment.
