Creating input library templates saves time: add ports and offshore bases to your input library so they are available to add to any case you create. Parameters set at the input library level are carried over to the case level. Leave blank any parameters that will vary on a case-by-case basis: you can complete these at the case level.

  1. Click on Input Library in the top bar.
  2. By default, you land in the port library. You can switch to Offshore base using the toggle in the top left.
  3. Click the + Add button on the left-hand side.
  4. Complete the required parameters.
    • Offshore base:
      • Only requires a title. Further parameters are set at the case level when you add the base to a case from your input library.
    • Port:
