Trimming Calculation Tool for Required Trim

Understanding the Trimming Calculation Tool for Required Trim 🚢

The Trimming Calculation Tool is designed to help mariners calculate the required trim with precision 🌊. Follow this step-by-step guide to achieve accurate and reliable results.

Getting Started with the Trimming Calculation Tool

Before you begin, ensure that you have filled in the necessary information on the Ship’s Data page. This data is crucial for ensuring the trimming calculations are accurate ⚓.

Step 1: Select Aft Draft Measurement

Start by choosing which aft draft will be used for the calculations:

• Hull or Rudder: Double-click to toggle between the two options. This selection determines the draft measurement used for calculating trim 📊.

Step 2: Enter Initial Data for Calculation 📝

Fields requiring input are outlined in red for easy identification:

• Actual Water Density: Input the density of water at the time of calculation.

• 6 Draft Readings: Enter the draft readings to calculate a matching draft for your ship’s hydrostatic tables.

Once this data is entered, the program automatically calculates the draft needed to align with the hydrostatic data.

Step 3: Input Hydrostatic Data 📈

Using the calculated draft, input the required hydrostatic data above and below the target draft:

1. Draft: Enter values for the draft above and below the calculated value.

2. LCF (Longitudinal Center of Flotation):

   • If your ship’s data provides LCF from the midship perpendicular, use the LCF Converter to adjust it to the aft perpendicular 🔄.

   • Alternatively, if hydrostatic data has been saved in the Hydrostatic Tables section of the Ship’s Data page, click Insert Data to populate the LCF values automatically.

3. MTC (Moment to Change Trim):

   • Enter the MTC for the actual water density manually, or use the MTC Converter to calculate it for a required density.

This flexibility ensures accurate and efficient calculations.

Step 4: Select Cargo Holds and Enter LCG ⚓

Indicate which cargo holds will be used for trimming:

• Cargo Holds and LCG: For each hold, input the LCG (Longitudinal Center of Gravity) from the aft perpendicular. Use the LCG Converter if needed 📐.

Step 5: Enter Cargo Distribution Details 📦

Input the total cargo to be loaded or discharged:

• Cargo Amount: Use + values for loading and - values for discharging.

Step 6: Specify Required Trim

Finally, enter the desired trim after the cargo has been distributed:

• Required Trim: Enter the trim in centimeters. Use + for trim by aft and - for trim by forward.

The tool will then calculate the necessary cargo distribution across the holds to achieve the required trim 🌟.

Final Steps: Save Additional Information and Print 🖨️

1. Enter Port Details: Add the port name, date, and any remarks 📅.

2. Save Data: Be sure to click all save buttons to confirm your inputted data 💾.

3. Print the Results: At the bottom of the page, click the Print button to generate a printout. Use the Print Icon in the top-right corner of the printout to print directly or save it as a PDF.
