🛠️ Before You Start Ship Trimming 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:

• General Info

• 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: Enter Ship’s Drafts

Input the following six readable drafts:

• FWD Port / FWD Starboard

• MID Port / MID Starboard

• AFT Port / AFT Starboard

Then click either "By Hull" or "By Rudder" to indicate which aft draft mark is used.

2️⃣ Step 2: Input Hydrostatic Data (Density 1.025 / Trim 0)

Use hydrostatic data for density 1.025 and trim 0. Enter values above and below the required point:

• Based on Corrected Mean Draft (m): to find LCF from A.P. (m) and MCT (tm/cm)

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

⚙️ Using Saved Hydrostatic Data

If you previously saved your hydrostatic data in the Hydrostatic Tables section:

• Click the Insert Data button

• The tool will automatically fill the required values

  
  

3️⃣ Step 3: Trimming Cargo Distribution

Enter trimming parameters:

For each compartment used "....." (e.g., cargo hold, ballast tank, fuel tank), input the numbers with following:

• LCG from A.P. to [compartment]

• Total Weight to Load/Discharge (mt):

  • Use ( + ) if loading

  • Use ( - ) if discharging

• Required Final Trim (+/- cm):

  • Use ( + ) for trimming by aft

  • Use ( - ) for trimming by forward

    💡 Need help calculating LCG? Click the Ship’s Calculator button for assistance.

The tool will calculate how to distribute the weight among selected compartments to reach your target trim.

🔐 All data is securely saved to your account and available in your personal Account.

4️⃣ Step 4: View Calculation Results

After the Ship Trimming Calculation is complete, check your results.

📌 These results reflect the impact of your entered data.

5️⃣ Step 5: Run the Calculation

Click the Calculation Icon

• Your input will be automatically saved

• All saved data is private and accessible only to your account

• A feedback message will confirm that the calculation has been processed

  🔐 Your data is secure and not visible to other users.

  
  

6️⃣ Step 6: Input Additional Data

Enter the final details:

• Name of Port

• Date

• Remark (optional)

Click the Save button.

🖨️ Print the Calculation

At the bottom of the page, you will find a PRINT button. Clicking it will open a new window with the printout form of your saved calculation — suitable for official use.

In the new window:

• A printer icon is located at the top right corner. Clicking it opens the print dialog to print or save as PDF.

• You can also press Ctrl + P on your keyboard to open the print menu directly.

  Always review entries before printing or saving.
