Intake Calculation

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.

The intake calculation function can be opened from one of the following modules:

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

  2. Select Voyage Intake Calculation.

Voyage Header Parameters

At the top, fields for changing the stowage and bunker properties for the entire voyage are displayed.



Stowage Factor

Cubic meters of space occupied by one metric tonne of cargo

DO ROB Voyage Start

Diesel oil at voyage start

DO LS ROB Voyage Start

Low-sulphur diesel oil at voyage start

FO ROB Voyage Start

Fuel oil at voyage start

FO LS ROB Voyage Start

Low-sulphur fuel oil at voyage start

Port Calls

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.




Sets the vessel DWT that is used in the calculation.

Water Salinity

One of Saltwater/Brackish Water/Fresh Water. Affects the water density.

Water Density

Density of the water at port. Higher value increases intake.


Intake draft reduction of the vessel. Lower value increases intake.

Safety Margin

Safety margin for the draft. Default value is 20%. Lower value increases intake.

Constant Reduction

Intake constant reduction of the vessel. Lower value increases intake.

Fresh Water Reduction

Intake fresh water reduction of the vessel. Lower value increases intake.

Loadline information

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


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.
