With the Intake Calculation function you can change parameters of a voyage to get an overview of quantities available for cargo at the port calls.

1. Click on a voyage in the list or board to open it in the drawer.

2. At the top right, click on Functions.

3. Select Voyage Intake Calculation.

Voyage Header Parameters

At the top, below the vessel-chip and voyage reference, fields for changing the stowage and bunker properties for the entire voyage are displayed.

Schedule Table

A table of all the port calls on this voyage is shown in this section. To change the intake reduction properties per port call, click a row to open a window where you can make adjustments. Some columns are hidden by default, and can be toggled on/off by using the "Customize Columns"-button in the top right corner of the table.

Chart

A mixed chart of the calculation results is generated at the bottom. Each port call has multiple graphs to show the reductions, cargo quantity and quantity available for cargo. The charts gets updated automatically when there are changes to the voyage header, port call, or vessel parameters.

Click on the legends at the top of the chart to toggle the display of a graph. Hover the mouse over the chart to inspect the values of each calculation data point.

Loadline Information

The loadline information table shows data on the voyage that might affect the intake. To change these values, you need to edit the vessel in the Vessels module in master data.

With the Sensitivity Analysis tool you can run calculations on a chosen parameter to evaluate risk.

1. Click on a voyage in the list or board to open it in the drawer.

2. At the top right, click on Functions.

3. Select Voyage Sensitivity Analysis.

Input parameters

Select a voyage parameter which is then adjusted by the numerical variance for each calculation.

Chart

Reading the chart

The chart shows all the calculated values for the voyage. There are 15 data points, with the current voyage displayed in the middle, with negative variance on the left side, and positive variance on the right side.

The value of the selected Voyage is specified with a blue vertical line. The figures you find in a small box above each point reflect the X-axis values for each point.

Hover the mouse over the chart to inspect the values of each calculation data point.

Moreover, you may find a table on the right from the Sensitivity Analysis chart. The table consists of the calculated values, placed in ascending order. The table may ease navigation among calculations.

Downloading the chart

The VMS provides powerful voyage tools for risk assessment and estimations on cargo capacity on port calls.

These tools are available from Voyages or Planning -> Fleet Plans

1. Click on a voyage in the voyages list or board to open it in the drawer.

The deviation calculation function offers a comprehensive analysis of the difference between the current voyage and the same voyage as if it were direct — from the ballast port to the last port call.

This function is particularly useful when freight rates are low, voyages must adhere to strict schedules, or deviations are required for compliance. It helps determine whether an additional detour can generate enough extra revenue to offset the added distance, time, emissions, and fuel costs.

Figure 1 shows the Deviation Calculation window, comparing the current voyage results (in the Loaded column) with a hypothetical direct voyage (in the Direct column). The Variance column highlights the differences between the two. By clicking Open Direct Voyage, users can review the direct route’s details (Figure 2). In this example, the detour with cargo generates higher revenue, making it a more favourable option.

Prerequisites:

• The Deviation Calculation function is available only for Estimate Voyages.
