🛠️ Before You Start Ship Maximum Cargo Calculation: Set Up Ship Data

Before using any calculation tool, it’s essential to enter and save your ship’s data. This ensures all tools use accurate data specific to your vessel.

✅ Complete Required Ship Data Sections

Go to the Ship Data page. You’ll find three main sections:

1. General Info

2. Dimensions and Weights

3. Hydrostatic Tables (optional but recommended)

📌 Mandatory Sections

You must complete the following before using any tool:

1. General Info

2. Dimensions and Weights

Once saved, this data is automatically used across all tools. You only need to enter it once — typically when joining a new vessel.

⚠️ Important: Enter all values carefully and double-check against official ship documents. Read any guidance or warnings displayed during the saving process.

🧱 Optional: Hydrostatic Tables

Adding hydrostatic table values is strongly recommended for faster calculations:

• Tools will auto-fill matching values from your saved data.

• If you haven’t saved your hydrostatic data yet, you can manually enter hydrostatic values during calculations — above and below the required value.

  💡 Tip: Always double-check input values above and below the target for accuracy.

  
  

1️⃣ Step 1: Define and Enter Data of the Limit Point of the Ship

This section helps determine the ship maximum cargo that can be loaded without exceeding the draft limit at a specific voyage point (e.g., port, canal, or zone).

Enter the mean draft at the limit point.

Enter the seawater density at the limit point.

Enter Hydrostatic Data for the Limit Point (Density 1.025 / Trim 0)

You must use hydrostatic data for density 1.025 and trim 0.

Enter values above and below the required point:

• Based on Draft (m): to find Displacement (mt)

  ⚠️ Enter all data carefully and accurately — incorrect values will affect the result.

⚙️ Using Saved Hydrostatic Data

If you have previously saved your hydrostatic table:

• Click the Insert Data button

• The tool will automatically fill in the required values

  
  

Enter Weights at the Limit Point

Enter the ship’s known weights:

• F.O. (mt) – Fuel Oil Remaining on Board

• D.O. (mt) – Diesel Oil Remaining

• L.O. (mt) – Lube Oil Remaining

• Slop/Sewage (mt) – Waste tank content

• Ballast (mt) – All seawater ballast

• Fresh Water (mt) – Potable and technical water

• Other Weights (mt) – Any other temporary/permanent weights

• SAG Allowance (mt) – Deduction due to SAG

• Constant (mt) – Ship's constant (crew, stores, etc.)

  
  

  The tool will calculate and display Ship Maximum Cargo On Board (mt) based on entered weights and hydrostatic data.

2️⃣ Step 2: Enter Data of the Departure Point of the Ship

This section helps determine the mean MID draft at the departure point needed to ensure the ship arrives at the limit point within the draft restrictions.

Enter the seawater density at the departure point.

Enter Weights at the Departure Point

Use the same format as in Step 1:

• F.O., D.O., L.O., Slop/Sewage, Ballast, Fresh Water, Other Weights, Constant

  
  

Enter Hydrostatic Data for the Departure Point (Density 1.025 / Trim 0)

• Based on Displacement (mt): to find Draft (m) and TPC (t/cm)

  ⚠️ Enter all data carefully and accurately.

⚙️ Using Saved Hydrostatic Data

If hydrostatic data is already saved:

• Click the Insert Data button to auto-fill the values

  
  

  The program will display the required Mean Mid Departure Draft (m) based on the cargo and conditions. This ensures compliance at the limit point.

3️⃣ Step 3: Enter and Save Additional Data

Enter the final voyage-specific details:

• Date

• Voyage

• Cargo

• Remarks (optional)

Click the Save button.

📂 A feedback message will confirm your entry is saved.

📌 Note: At this step, all data has been calculated and saved.

🖨️ Print the Ship Maximum Cargo Calculation

At the bottom of the page, click the PRINT button:

• Opens a new window with the formatted printout (official format)

In the print window:

• Click the printer icon (top-right) to print or save as PDF

• Or press Ctrl + P on your keyboard

  Always review entries before printing or saving.
