Daily Logs, no Measured Fuel Consumption (MFC)


The Running Machinery Daily Log is a method of tracking daily use of vessel, observations of major running machinery and estimating fuel consumption.  The Standard  Daily Log is illustrated (wherein the engines and generators do not incorporate fuel consumption metering.).


A Measured Fuel Consumption Daily Log is also provided.  You must choose an appropriate log before making any Daily Log entries for your vessel.  


Entries shall be made to this log every day, even if not under way, for purposes of tracking officers in charge and ad hoc information.  A typical log entry would include Engine Hours (port and starboard) that were found at the beginning of the log entry (or Advanced from a prior entry), port/starboard Generator hour readings at the end of the logging day, designation of Captain, First Officer and Engineer, date of the log entry and a description of events (Daily Diary).  


To practice with the MFC Running Log choose M/V Abby Lane from the Vessel Information Module.  Also note that an alternate vessel cannot be chosen from within the Running Log module.


Those fields shown in white or yellow type with black background are calculated fields and cannot be changed by direct entry.  For instance, when the Hours and Total Fuel Used Main Engines fields are filled, the Total Main Engine Hours/2 (both main engine running times divided by two as an average running time) the Average Consumption (per hour) of the Main Engines are calculated.  The Generator hours and Total Fuel are similarly calculated when the Average Consumption GenSet is entered.  The Total Fuel This Trip (shown below) is a calculated field.  


The Total Fuel Used Main Engines and Average Consumption GenSet fields are estimations based on experience.  Occasionally you'll need to make a Sounding Adjustment to make Total Fuel On Board calculations accurate.  If the Sounding Adjustment is constantly over or under the estimated usage you'll gain insight into the accuracy of prior estimates.


When tabbing from field to field VMS will skip those fields that are not normally updated manually (like Hours Start).  The tab order begins with Daily Diary.  


If  Advance Record method was used to create the current record the Start fields will be filled automatically.  If necessary, you may manually place your cursor in any Start field to change it's value.  When entering these fields you may find it easier to increment or decrement any of these numeric fields by using the keyboard rather than typing the number.  


The cutout at left demonstrates final adjustments that may be made to the Total Fuel On Board calculations.  


After bunkering you may show the amount of fuel taken on board in the Fuel Added field.  If you transfer fuel to another vessel you may enter the number of gallons in the Fuel Transferred field (note: this is entered as a positive value, or may be incremented/decremented with the minus or plus keys on your keyboard).  


Finally, in this example, a sounding observation (tankage) indicated that there were 150 more gallons on board than estimated, and that value was entered as a positive number (if the number had been negative one would first enter a "minus sign," then the number).  


Important Note:  The Sounding Adjustment field is necessarily programmed to accept either a positive or negative value.  So the minus sign (if used) does not increment or decrement as it does in all other number and date fields.  After all running times, fuel added, fuel transferred and sounding adjustments are entered VMS will calculate the Total Fuel On Board.


The Advance Record button will create a new record using some data from the record currently viewed.  It will advance Hours Ending to Hours Starting, clear those entries that normally change from log to log (like Diary) and Total Fuel On Board (quantity at the end of the previous day's record) will become Total Fuel Start (fuel presumed to be On Board at the beginning of the current running day).  After advancing the previous day's record you'll only need to enter Diary information, re-select the appropriate officers (if necessary) and fill in the Ending Hours fields.


You may hide a record (usually because old but you don't want to delete it) by checking the box shown at left.


You may examine a record hidden by the action above by checking the box at left, and change it's hidden status once revealed.  Checking this box will open all archived records for this session only.  When you reopen this module only the visible records will be shown in the index choices.  However all records are available in the QuickView.


Printed reports from this log display the same calculations as the parent data module. By choosing a range of dates when printing you'll be able to produce a history of the vessel's activity for a specified length of time.
