    • ROBs: Add an ROBs tab to the Port Activities form for the voyage and be able to edit in-port ROBs for that Port Activity, for reporting purposes, after the date and time have been added.

Action Types

Each term can have one of the following Act (Action) Types. Only the nine Action Types mentioned in the table below have an effect on the Laytime Calculation. A typical set of Action Types for loading or discharging cargo follows:

  • PS (Port Action Starts)

  • NR (NOR Tendered)

  • OS (Operation Starts)

  • OE (Operation Ends)

    • If there is not a matching OS to OE an error will occur - "ERROR - Port has more OE activities than OS activities“

  • PE (Port Action Ends)

    • IS/IE pairs (Interruption Starts/Ends) and DS/DE pairs (Delay Starts/Ends) can be inserted between OS and OE pairs to log interrupts and delays.

Related Configuration Flags



Duplicate Activities for Cargoes and Berths

When this flag is enabled, those Port Activities that are flagged with the Cargo and/or Berth check box in the Port Activities form and assigned to a template will duplicate for the number of cargoes/berths that have activities at that Port.

Apply Code Pair in Port Selection

When enabled, selecting a port activity that is part of a code pair in the Port Activities form automatically pulls in the other activity from the pair directly underneath it. This makes it easier to add in both the start and end time of an activity that requires a duration.

Where applicable, Voyage Reporting forms validate that both paired port activities are present.
