Short Description

An estimate can be simple, for example it can be a delivery and a redelivery port only or consist of a combination of a few or multiple port calls and routing points. The Ports  Rotation field lists at any time the full voyage route (or voyage port rotation), i.e. displays at all times all port calls and routing points (if any). A port rotation can consist of delivery port, redelivery port and an unlimited number of load, discharge and/or extra port calls, routing points and canals. Special routing point codes can also be added manually to avoid high risk piracy areas.

There are six port call/routing point options when building a port rotation:

Dataloy VMS calculates and displays the shortest route for the entered rotation in the Ports Rotation field, automatically inserting, where needed, available default routing points. The Voyage Estimate module allows for an unlimited number of port calls, routing points etc. to be added to a time charter calculation. The Ports Rotation field lists by default the delivery port and then the redelivery port. All other port calls are listed where entered and manually added to the Ports Rotation field. Each entered port call will displays as individual rows, each row containing relevant port call data. Additional (or extra) ports are any type of port call aside from deliver, redelivery, load and discharge ports, for example bunkering, and are like delivery and redelivery ports only linked to the voyage (load/discharge ports are dependent on a cargo).

Routing points are also used when creating voyage rotation patterns and can be defined as specific locations that a vessels pass through when en route between port calls. They are linked to the voyage only. Canals are routing points that will by default show as a separate port call in the port rotation in order to address the time and cost involved with canal passages directly to the canal. The canal time and cost has a direct impact on the result and length of a voyage. Each routing point (including canals) is defined by a unique code and name. 

Dataloy VMS always schedules the shortest port rotation route and piracy routing is not automatically considered. Therefore, to date, nine piracy routing points have been added to retrieve the most accurate distance based on current routing advice in high risk areas. The piracy routing points are not added to a voyage rotation by default, but must always be entered be manually and only using their respective piracy routing code.

Long Description

To Enter Delivery and Redelivery Ports 

  1. Building a port rotation in a time charter estimate requires the prior entry of a vessel and existence of a ballast port. 
    Note: If no ballast port is automatically retrieved from operations upon vessel name entry or manually entered, the system will automatically recognise the very first entered port call (irrespective of port type) added to the full time charter calculation as ballast port also. The ballast port field will populate accordingly.

    Example:


     
  2. Enter applicable delivery and redelivery ports to the calculation either by
    1. port entry in the Delivery and Redelivery fields of the Main Calculation field (Time Charter (TC) Contract panel):
      Note: A minimum of one delivery and one redelivery port must be entered. ONLY delivery and redelivery ports can be entered in the Time Charter (TC) Contract panel. Manual entries are required for all other port call entries.



      1. Enter the delivery port under Delivery.
        Note: Need only to enter the first few characters of the port name. Dataloy VMS will search available ports and display the first matching entered characters, for example enter "VISAK" and "VISAKHAPATNAM" displays. 
      2. Enter the redelivery port under Redelivery (RED marking = required field).
      3. Click Enter. The corresponding port rotation will automatically display as rows in the Port Rotation field, including reason for call (RED, DEL) and the calculated distances between ballast, delivery and redelivery ports and the number of sea days needed for the voyage (Waiting panel, Main calculation field). If the delivery port and the ballast port are identical, the distance will list as zero.

        Example: 

         
         
      4. Go to Step 3.
    2. or by manual entry into the Port Rotation field:
       Note: Any type of port call can be entered manually to a rotation. Manually added delivery and redelivery port calls ONLY displays in the Port Rotation field and must be added manually in the Delivery and Redelivery fields of the Main Calculation field (Time Charter (TC) Contract panel). 
      1. In the Port Rotation field, select the port call to add a port call before or after in the rotation - it will highlight. If initial port call is to be entered - go to next step. 
      2. Either
        1. click Insert and from the menu, depending on where in the new port is to be added, select Before or After
          Note          : If no previous entry to the Port Rotation field has been made - the Before option will be disabled. Activates after first port call entry. If so, select After.

           

        2. or go to the Port Call menu and from the drop-down select Insert and then either Before or After depending on where the new port is to be added.



      3. The Select Port to Insert pop-up will open.
         

         
      4. Fill in the fields as follows:
        1. Enter either 
          1. the port call name under Port Name or
          2. click the Triple Dot Selector next to the field. A pop-up with a list of port calls will open. Select port call and click OK.

            Example:

             

        2. Enter either
          1. the reason for call under Reason for Call or
            Note: Defaults to Loading.
          2. click the Triple Dot Selector next to the field. A pop-up with a list of input values will open. Select reason for call and click OK.
            Note: Reason for call will here be either Delivery or Redelivery depending on which is being entered. 
        3. Click OK. The pop-up will close and the new port call will display as a row in it's designated place (i.e. before/after the selected port call) in the Port Rotation field, including reason for call (DEL, RED) and the distances between ballast, delivery and redelivery ports). If the initial port and the ballast port are identical, the distance between will list as zero.
        4. Repeat until both delivery and redelivery ports are entered and displayed.
      5. Go to Step 3.
  3. The Ports Rotation field lists by default delivery port first and thereafter discharge port. Entered port calls will displays as individual rows, each row containing relevant port call data. 

    Example:



    1. The populated row fields can be manually overridden (except #, Cost Voyage Currency, L/D Days and In Port) - edit if applicable: 
      1. List (#) field lists port call order according to reason for call type.
        Note: Automatically lists delivery port before redelivery port, irrelevant of order of entry (if ports were entered manually). All other port calls can only be entered manually and will display, irrelevant of port call type, in the place they were entered in the port rotation.         
      2. Enter applicable routing point (if any) under Routing Point.
        Note: Normally populated with elsewhere entered data. 
      3. Enter port call name under Port Name.
        Note: Will be populated with elsewhere entered data. 
      4. Enter reason for call under Reason for Call.
        Note: Port call row fields for delivery and redelivery ports normally populated with elsewhere entered data.
      5. Miles automatically displays the distance in nautical miles between port calls (retrieved from the DDT).
        Note: If the initial port call and the ballast port are identical, the distance will list as zero. All distances can be manually overridden.
      6. Enter port cost in applicable currency under Cost LC (Cost Local Currency).
        Note: Only required for ports prior and after the delivery and redelivery ports. Port costs for the delivery port, the redelivery port and the ports inbetween are to be paid by the Charterer.
      7. Enter port cost currency under Currency.
        Note: Defaults to USD. 
      8. Cost Voyage Currency displays the port cost in the voyage currency.
      9. L/D Days (Load/Discharge Days) displays the time allowed to load/discharge (in days).
        Note: For TC this column is not applicable.
      10. Enter the individual extra days estimated to spend in each port under Xtra.
        Note: Defaults to 0.5 days. The total of all entered extra time spent in all port will display under Extra Port (Main Calculation field, Turnaround panel). Note: ONLY applicable to ports prior to delivery port and after the redlivery port. Defaults to 0.5 days. The total of all entered extra time spent in all port will display under Extra Port (Main Calculation field, Turnaround panel). 
      11. In Port displays the total number of days in port (i.e. the sum of L/D DAYS and Xtra days).

To Add Additional Port Calls (Load, Discharge, Extra Ports)

  1. Open the time charter calculation to add a port call/s to. Its fields will display.
    Note: All port calls entered into a time charter calculation display in the Port Rotation field. A    dding additional port calls requires the prior existence of a vessel and a ballast-, delivery- and redelivery port. All port calls can be added manually, but ONLY delivery and redelivery ports can be added through the Delivery and Redelivery fields of the Main Calculation field (Time Charter (TC) Contract panel). An unlimited number of load, discharge and extra ports may be added to an estimate (and to any estimate). Extra ports are any type of port call aside from load, discharge, delivery and redelivery ports, for example bunkering.
  2. Enter applicable load, discharge and/or extra ports:

    1. In the Port Rotation field, select the port call to add a port call before or after in the rotation - it will highlight. If initial port call is to be entered - go to next step.

    2. Either
      1. click Insert and from the menu, depending on where in the new port is to be added, select Before or After.
        Note: If no previous entry to the Ports field has been made - the Before option will be disabled. Activates after first port call entry. If so, select After. 


         
      2. or go to the Port Call menu and from the drop-down select Insert either Before or After depending on where the extra port is to be added.


         
    3. The Select Port to Insert pop-up will open.


       
    4. Fill in the fields as follows:
      1. Enter either 
        1. the port call name under Port Name or
        2. click the Triple Dot Selector next to the field. A pop-up with a list of port calls will open. Select port call and click OK.

          Example:


           
      2. Enter either
        1. the reason for call under Reason for Call or
          Note: Defaults to Loading. 
        2. click the Triple Dot Selector next to the field. A pop-up with a list of input values will open. Select reason for call and click OK.
    5. Click OK. The pop-up will close and the new extra port will display as a row in it's designated place (i.e. before/after the selected port call) in the Port Rotation field, including selected reason for call. The estimate will automatically recalculate and update as a parameters changed.

      Example:

      Manually added extra port: Mumbai. Only displays in the Port Rotation field.


    6. Repeat Step 2a-e as applicable until all load, discharge and/or extra ports are entered with accurate reasons for call. For each entered port call the voyage route pattern will update.
  3. Complete the details for each port call as applicable in the Port (or Port Rotation) field (see To enter load and discharge ports, Step 3).

Extra Ballast Ports

Adding an extra ballast port to a voyage rotation, for example the end of a voyage rotation, is possible by treating the intended extra ballast port as an extra port. To add an extra port - go to To add additional port calls (load, discharge, extra ports).
 

Routing Points

  1. Routing points can be defined as specific locations that a vessel pass through when en route between port calls and are used in Dataloy VMS when scheduling voyage rotation. Prerequisites are the prior entry of a vessel and existence of a ballast, delivery- and a redelivery port. (View list of most common routing points, go to Routing Points, Canals, Piracy Routing Lists).
    Note: ONLY use a routing point's individual code when entering a specific routing point, (for example GI=Gibraltar Strait), or it will not be recognised as a routing point. Routing points are only linked to the voyage and an unlimited number of routing points may be added to an estimate.
  2. Routing points can be added as part of a voyage rotation and used to re-route a voyage by manual override.
    1. Add routing points either by 
      1. automatic scheduling by Dataloy VMS:
        1. Enter applicable ballast, delivery and redelivery ports in the Main Calculation field (Vessel panel and Time Charter (TC) Contract panel).
        2. Dataloy VMS calculates and displays the shortest route for the entered rotation in the Port Rotation field, automatically inserting, where needed, available default routing points.
          Note: The routing point code of each added routing point will display in the Ports Rotation field under the Routing Point column in the row of the port call it precedes. Can be manually overridden.

          Example:

          Port rotation: Rotterdam (DEL)/New York (RED), Ballast: Kandla
          Displays in the Port Rotation field (including routing points) as: GH-Rotterdam/New York (NY) (GH=Cape Agulhas (Cape Good Hope))

           
      2. or by manual entry into the Ports Rotation field:
        1. Click the row field of the port call to be preceded by a routing point under the Routing Point column - it will highlight.
        2. Enter either
          1. new routing point code into the row field or
          2. click the Triple Dot Selector that will appear next to the field. A pop-up with a list of routing points will open. Select routing point and click OK.

            Example:



        3. Repeat as applicable to the routing point row fields until all applicable routing points have been entered. 
    2. Re-route a voyage rotation:
      1. Open the time charter calculation with the port rotation to be re-routed.
      2. In the Port Rotation field, click the row field of the port call to be preceded by a routing point/have prior routing point/canal amended under the Routing Point column - it will highlight.
      3. Enter either
        1. new routing point code into the row field or
        2. click the Triple Dot Selector that will appear next to the field. A pop-up with a list of routing points will open. Select routing point and click OK.
      4. Selected routing point code will appear in the row field. 
      5. Remove canal row if re-routing from canal - if not - go to Step viii:
        1. Click the canal row to be removed - it ill highlight.
        2. Either
          1. Click Remove 


             
          2. or go to the Port Call menu and from the drop-down select Remove.


             
      6. A pop-up opens asking to confirm removal.
      7. Click Yes. Selected row will delete.
      8. The calculation will update and recalculate as parameters changed.
      9. Repeat as applicable until re-routing is complete.  

Canals

Canals are routing points that will by default show as a separate port call in the port rotation in order to address the time and cost involved with canal passages directly to the canal. The canal time and cost has a direct impact on the result and length of a voyage. To each canal a default passage time is added automatically added to the calculation, for example the Suez Canal = one day time passage (time default can be manually overridden by Administrator/Super-user). The Canal passage cost must be manually entered under the Cost LC (Cost Local Currency) column and reason for call will display as C (=Canal Passage). Dataloy VMS only treats canals as routing points when routing between port calls, but displays canals as port call rows in the Port Rotation field. As canals are routing points, they are only linked to the voyage. (View list of most commonly used canals, go to Routing Points, Canals, Piracy Routing Lists). 

Canals can be added as part of a voyage rotation either by

  1. automatic scheduling by Dataloy VMS:
    1. Enter applicable port rotation string, i.e. delivery, redelivery, load, discharge, extra ports, etc. in the Port Rotation field.
    2. Dataloy VMS calculates and displays the shortest route for the entered rotation in the Ports (or Port Rotation) field, automatically inserting, where needed, available default routing points and canals.
      Note: The canal will be inserted as a row before the port call it precedes. Can be manually overridden.

      Example:

      Port rotation: Rotterdam (DEL)/New York (RED), Ballast: Kandla

       
  2. or by manual entry - can only be entered as port call and will only display in the Port Rotation field.
    1. In the Port Rotation field click the port call to enter a canal before or after in the rotation - it will highlight.
    2. Either
      1. click Insert and from the menu, depending on where in the new port is to be added, select Before or After.



      2. or go to the Port Call menu and from the drop-down select either Before or After depending on where the extra port is to be added.



    1. The Select Port to Insert pop-up will open.


       
    2. Fill in the fields as follows:
      1. Enter either
        1. the canal name under Port Name or
        2. click the Triple Dot Selector next to the field. A pop-up with a list of port calls will open. Select port call and click OK.

          Example:


           
        3. Enter either
          1. the Canal Passage under Reason for Call or
            Note: Defaults to Loading.  
          2. click the Triple Dot Selector next to the field. A pop-up with a list of input values will open. Select Canal Passage and click OK.
      2. Click OK. The pop-up will close and the newly entered canal display as a row in it's designated place (i.e. before/after the selected port call) in the Port Rotation field, including selected reason for call. The estimate will automatically recalculate and update as a parameters changed.

Removing a canal from a port rotation requires the removal of the port call after in the port rotation before the canal can be removed. As Dataloy VMS always schedules the shortest route, the system will automatically reinsert the canal if it is removed without first removing the following port call (unless voyage is re-routed using routing points go to Routing points, Step 2b). Removing the port call enables the canal to thereafter be removed.


Piracy Routing

Dataloy VMS always schedules the shortest port rotation route and piracy routing is not automatically considered. Therefore, to date, nine piracy routing points have been added to retrieve the most accurate distance based on current routing advice in high risk areas. The piracy routing points are not added to a voyage rotation by default, but must always be entered be manually and only using their respective piracy routing code. 

(View list of available piracy routing points and codes, go to Routing Points, Canals, Piracy Routing Lists).


To Rotate Port Call Order

The Port Rotation field lists all entered port calls in the place where they were entered. Only the delivery port will by default automatically be inserted before redelivery port. Each entered port call display as individual rows, each row containing relevant port call data. Port call order can be changed (i.e. port call order rotation) in the Port Rotation field.

To move a port call in a time charter rotation:

  1. Open applicable time charter calculation. Its fields will display.
  2. In the Port Rotation field click the port call to be moved - it will highlight.
  3. Either
    1. click Move and from the menu, depending on which way the port call is to be moved in the rotation, select Up or Down
      Note: The port will move one step, i.e. be sorted above or beneath the port calls either preceding or following it.



    2. or go to the Port Call menu and from the drop-down select Move and then either Up or Down depending on where the port is to be moved to.

       
       
  4. The estimate will automatically recalculate and update as a parameters changed.
