Guidance

1.  Intro
This is demonstration for dashboard embeded from Tableau. Visitor to this private page is able to get hands-on feeling how the dashboard will work dynamically to assist your analysis (Self-BI).
This demo/example dashboard is prepared to analyse and monitor the speed, consumption of the vessel, using CP speed or target speed, consumption as benchmark. Speed consumption analysis is common task for not only vesssel operators, but it is essential analysis to run the vessel at the most efficient and economical way to increase the earning and also to avoid Spd&Con claims.  Dashboard would connect to live data and its source, pulling latest data without any action for extraction.  
Speed consumptions analysis is always troublesome, since it takes huge amount of time to collect, clean and filter data to reach to the result of it. Speed consumption analysis is inevitable due to various reasons, such as claim handling, finding optimum speed under given circumstances, determinng TC descriptions, copmarision with sister or similar type of vessel, etc etc.  The beauty of dashboard is to reduce the amount of time (usually days or weeks) to minutes. 
Deep analysis over the speed consumption would surely bring additional value to you, by spotting usual event super quickly, trouble shooting, getting accurate performance of the ship, preparing claims documents or counter in pursuasive way, or rating vessels under the fleet to get lessons for future order of the ships.
This dashboard is just an example prepared to demonstrate how we visualize vessel data and how users play around with dashbaord under the circumstances close to the "live". 
Some people misunderstood, like "dashboard = or nearly = Excel". but not true. Test dashboard and see they are completely different spices. 
Hope you would feels a sense of "beauty" of the visualization through this demo dashboard.
 
 
Note : The dashboard is embeded from other ongoing site, and adjusted to fix to website, resulting in smaller size of screen where chart and other dashbaord elevets are squeezed.  Actual dashboard is capable to fit nicely to any devices, destop, mobile and tablet.
2. Dashboard Elements
Chart 1

This bar chart is a track record of actual bunker consumption used for steaming, propelling purpose, clored by different bunker grades. (Left Axis)  Gantt chart (Right Axis) is CP or targeted bunker consumption at given speed. User can flexibly change the speed, bunker consumption matrix based on figures which is deemed to be appropriate for this paricular vessel based on past record, or power curve at the time of delivery of the ship. Or user can use CP speed & Consumption warranty figures as target speed, to analyse and monitor the actual performance of the vessel.

"L" and "B" on the top of bar indicates the vessel condition, either Laden or Ballast on eac reporting day.

Chart 2

Similar chart to Chart 1, but bar chart is colored by bunker consumption source, either 1) Mail Engine, 2) Boiler 3) Generator, fiting to tankers which fit boilers onboard. (Left Axis) On the right axis and green dot indicates the average engine load in %  of each reporting date.

Chart 3

Comparision of 1) Actual bunker consumption and 2) consumption at CP and/or target speed which user define. Actual speed is not always intenger, but usually speed consumption matrix are. To conduct the analaysis, dashboard run the proportional distribution based on user defined speed and consumption matrix based on actual speed each day.

Circle and square shape at the bottom indicate the speed instruction from responsible operators, like "full speed", "most eco" for reference.

Chart 4

Tracking average speed and Beaufort Scale of each reporting date. This visualization give quick insight the relationship between actual speed gained and weather factor of the day to check the speed is affected by bad weather or not.  BF scale is based on master's figure, however, user could replace it with scales which are provided with vendors such as weather routine companies, provided that data schema matches.

Parameters

Speed consumption matrix for both laden and ballast conditions, the users need to preset before starting analysis.

This stands as benchmark to gauge the amount of deviation of actual performance of vessel.  User have flexiblity to put TC description, warranty figures, 

On this example, to make the story simplified, the matrix starts from 10 knots, ending wat 15 knots per one knot, but user can define and designe its own matrix template. 

Filters & highlighters

This is a list of filters and highlighters. Filters are most used functionalities on dahsboard to trim data as users wish. To change the range within given timeline, exclude data which is out of allowable range, such as weather and vessel conditions. Visualization gives quick insight to locate the "error' data., by detecting spike and deviation. User filter function to eliminate  error data user don't want to include for analysis. The beauty of analysis  on dashboard is all the charts visually appeal the change as a result of actions over new filtering in quite a responsive manner.

On this example, we put filters of 1) Data range 2) Main Engine hours (from noon to noon) 3) Repored average speed (noon to noon) 4) B/F scale 5) Consumption calculation method, either raw number (sometime consumption is basis 10 hours , 12.5 hours rather than 24 hours exact) OR bunker consumption is proportionated basis actual main engine hours 6) Vessel condition (Laden or Ballast) 7) Reporting date

 

User can add any other type of filters such as draft %, deadweight, current dir, or anything to drill down the performance further.

 

Date highlight bring user to the target date instantly, as wel as vessel consition, speed instruction, bunker grade etc. 

3. Dashboard Actions
Filtering

Select from dropdown menu.

Fix the min/max range by hitting the number and box pops up to enter the new range.

Filter function is most used actions on dashboard.

Highlight

Select date users want to highlight from dropdown menu, click the color or shape legend to view only the associated data.

Tooltip

Mouth-over or click any part of chart elements. Tooltip pops up. User view the underlying data, including data set which is not visualized within charts.

Grouping

Select the range over the chart by clik and dragging mouth. The selected area wil be highlighted and make a group. Can count the number of items selected and sum of data.

4. How to play around

Set up the speed consumption matrix as you like.

You will see some of chart elements will change, such as CP / target consumption gantt chart and bar chart for deviasion.

Change the filters to trim data, visualization would keep changing, reflecting your sort
