Case: A fleet of six vessels to be scheduled for half a year
This is an illustration on how LNG4004 can be used to schedule a fleet of six vessels for first half 2013.
The ships to be scheduled are described by their capacities such as speed/cons, cubic capacity, dwt et.
Before a schedule is generated, the ships availability are specified by the port and date the vessels are open for scheduling:
The fleet may be a combination of own vessels (i. long term tc) and spot charters taken in for a trip or period.
LNG4004 will calculate what market opportunities best fit within the schedule.

The cargoes or jobs to be lifted are specified by

  • Load port

  • Discharge port

  • Port costs

  • Type of LNG (Retrieved from internal cargo data base with specific gravity, heat content etc) This is used to calculate cargo intake that is determined by ship's dwt and cargo capacity, also taking into account any draft restrictions in load or discharge port

  • Most important are often laydays for loading and discharge.

  • Distances between ports are retrieved automatically from the internal database.

  • Canal transits through Suez and Panama are handled automatically and tolls are calculated based on updated tarifs and data for transit times.

The strength of LNG4004 is the ability to generate a fleet schedule from scratch. The user specifies where vessels are open (port and date) along with a list of the cargoes to be lifted.
LNG4004 is therefore doing the same job as an experienced chartering manager or scheduler
But LNG4004 will save a lot of time - and in most cases LNG4004 will find a schedule that is significantly better than a manual schedule.


Visual presentation of the schedule generated by LNG4004.

  • When LNG4004 has calculated a schedule that is feasible (i.e. meets all contractual constraints and taking into account all spot opportunities) the user can retrieve a visual presentation of the cargoes allocated to the various vessels.

  • A special color will show where vessels have been waiting for loading or discharge.

  • The user may also work interactively with this visual schedule by moving around cargoes to the vessels. By pressing a command button "Update vessel", the user can immedfiately see whether his new schedule is feasible or better than the one generated by LNG4004.

Various reports are available for the user to understand what the schedule implies.
The most detailed report is a voayeg estimate showing the voyage results for each ship/cargo in the schedule.

Report - Voyage summary
Another report shows a summary for each ship with data on loading date, cargo intake, days voyage, TC result etc

Fleet summary report
Show total results for the entire fleet. Cargo intake, Gross tc result, TC pr day, waiting time in percent of total time etc.

Special reports can include:
Detailed position list with ETA and ETD.
Again note that this position list is the result of the fleet being scheduled by a computer program called LNG4004.

Emissions and GHG emissions report
LNG4004 includes a very powerful tool that generates the GHG emission on the various voyages. The user may also include CO2 as a 'cost' in his scheduling and thereby generate schedules that are 'greener'.
