4. Monitoring Your fleet performance is monitored during voyage 24 x 7 in view of Daily Targets (Daily speed, Daily FO consumption, and Daily RPM) and Leg Targets (Total FO consumption, Passage Time, ETA) you set up for each voyage. Target Management Target Management in the sub-menu pane lists up your vessels illustrating business risks with traffic lights. Red lights on Daily Monitoring indicate one (or some) of ship reported values is in excess of your daily targets, and Yellow lights indicate one (or some) of them is in tolerance range Leg Monitoring applies the same mechanism comparing your targets to Weathernews estimates for the leg. Target Management menu remembers the last accessed item Daily Monitoring or Leg Monitoring - and shows it when accessed next time. 13
Ship Monitoring click on a ship name in the Target Management fleet list (previous page) or search your desired ship name and click on the ship name. Ship Monitoring page displays detailed information. clicking on the map pane shows enlarged route map. When zoomed in, wind conditions experienced by the vessel from departure to date as well as expected wind conditions on the remainder of the voyage will be shown along the route. Table items are highlighted in red or yellow corresponding to business risk analysis represented by traffic lights in Target Management table list (previous page). Daily ship reported values are shown in graphs with target threshold lines. Wind, Wave and Current data depicted are Weathernews verified data from departure to today, and Weathernews expected data on the remainder of the voyage. Ship reported wind and wave data are also shown on the graphs for your reference. Pressing Edit button allows you to set up and modify target values. Press the button again to apply the updated targets to Daily Target management. About Target Management shows tolerance types employed for your company. (See the next page) 14

Fleet Display Fleet Display in the sub-menu shows your vessels locations with weather information on the world map. Ship icon color is automatically updated corresponding to fuel consumption risk examined in Daily Targets and Leg Targets. Adjust zoom size by clicking on button. clicking on a ship icon shows a pop-up window where you can choose Route or Detail. Selecting Detail shows Ship Monitoring information of the selected vessel. (See Ship Monitoring ) 16
clicking on Route button shows the voyage track from departure to the current date and the remainder of the voyage to the destination. clicking oni << and >> button allows you to animate ship position with associated wave conditions on selected dates. To hide the vessel s track click on X button in the following pane. You can zoom in the map by double-clicking on the map. The zoomed map shows wind conditions from departure to the destination along the route. Note: Future track is not depicted unless Optimum Ship Routeing (OSR) or Oceanrouteing (O/R) or Performance Monitoring (PM) is employed. 17
5. Evaluation Performance Evaluation Ship-specific performance is analyzed based on Weathernews verified weather/current data on actual voyages. Search a ship or pick up ship(s) in ship groups. Check your desired vessel name box(s), and press Ship Evaluation button (for single ship analysis) or Fleet Evaluation button (for multiple vessels analysis). Select one of analysis periods in the options. You will have the analysis charts and table as shown in the next page. 18
(a) (b) (c) Single Vessel Analysis Analysis charts included are; (a) Daily FO consumption vs RPM analysis chart (b) Daily Speed vs RPM analysis chart (c) FO consumption vs Speed analysis chart Speed and consumption analysis table at each MCR (%) and RPM is also included. Multiple Vessels Comparison Multiple vessels performance can be compared on the charts and table with your preferred analysis parameters. 19
+ You can examine ship reports on each analysis chart by clicking on your preferred chart. The chart will be zoomed in with ship reported QRT data during the selected period. You can further zoom in the chart. Press and hold down the mouse button, then drag the pointer across the screen to define the desired area. A rectangle appears on screen to show the selected area. To zoom out, click on zoom out button. To change analysis parameters, press Edit button below the analysis table (previous page). Modify the parameters of the table as you wish. Press Go! to reflect your preferred parameters on analysis. 20
6. Setting For your quick reference the following ship groups are set up. All Ships including all vessels which were operated by your company (or section). This should be useful for Evaluation menu. Your Section fleet. In addition to these pre-set groups, you may add new groups with your preferred ships and group names. 1 1 click on button. 2 2 You will see a group set-up pane.

Appendix A : Ship Performance Assessment Ship performance speed and fuel consumption is analyzed at each given RPM in a calm sea conditions based on ship reported QRT data. QRT data for the period less than 22 hours steaming time and more than 26 hours are not taken into account. FO consumption analyzed is that of main engine converted to 24 hours consumption. In the analysis, the following parameters can be configured by users arbitrarily. Analysis period(s) Load condition - Laden or Ballast Draft Weather conditions Ship report type - "Verified data" or "Raw Data" Deviation Range Analysis period(s) arranged are (i) Last 12 months, (b) From the Last Dock to date, (c) Year to Year comparison during last three year periods, (d) Dock to Dock Comparison, (e) Event-Divided Period Comparison and (f) your preferred period(s) setting. Weather conditions have four categories - Fair, Moderate, Heavy and Severe where each category consists of wind speed and/or wave height which are determined by users. The weather used in Performance Evaluation is Weathernews' verified data, where Master's reported weather is retained, but not used in the Performance Evaluation. "Verified data" applies only where the vessel concerned is under OSR service: The nature of OSR means that any data irregularity will have been corrected by our OSR staff, where our staff may contact the ship master for data confirmation/update, or the data may not be included in ship performance analysis when it still looks suspicious even after our scrutiny with the help of the ship master. "Raw data" means that the QRT reports sent from the ship are imported direct into Weathernews QRT database and employed in EXSITE. Therefore the curves depicted based on the raw QRT data may include errors and/or suspicious elements. Deviation Range is used to filter out "Raw Data" as well as "Verified data" by the customer setting their own data deviation limit parameters (e.g. 10%) Note the vessel's speed at any given RPM is through-water speed, calibrated taking into account current factor calculated in the vessel's heading direction (See Fig 1). For example, if a vessel's reported over-ground speed is 15 Knots, and the calculated current factor is 0.5 Knots in the direction of ship heading, the "through the water" speed would be 14.5 Knots. Fig. 1 How to calculate current factor 25
Daily FOC [mt/24h] Daily FOC [mt/24h] Step 1: FOC-RPM correlation analysis In order to have FOC-RPM correlation analysis curve the actual fuel oil consumption included in QRT reports are decomposed into the following two components. FOC actual = FOC calm (RPM, Loading condition) + ΔFOC(RPM, Weather condition) Note ΔFOC(RPM, Weather condition) can be neglected when the item of interest is the actual FOC in a calm sea only. You may employ deviation filtering function when spikes and/or suspicious data are seen on the chart, which makes the data set as follows. (1-R) FOC calm < FOC actual < (1+R) FOC calm Through this process you have the revised FOC-RPM correlation analysis curve as shown in Figure 3. Fig.3: Revised FOC-RPM correlation analysis curve In this case deviation range R=50% is adopted. This is followed by the following regression analysis which is effective to minimize deviation between the actual FOC and modelestimated FOC. 175 150 (FOC actual - FOC calm (RPM, Loading condition)) 2 125 100 This is the initial FOC-RPM correlation analysis curve as shown in Fig. 2. 75 50 fitting curve reported data 25 Fig.2: Initial FOC-RPM correlation analysis curve Some spikes are seen between RPM 60 and 80 in this example. 0 20 40 60 80 100 RPM 175 150 125 100 75 50 25 0 20 40 60 80 100 RPM fitting curve reported data Step 2: Ship Speed - RPM correlation analysis The same steps are applied to the Ship Speed - RPM correlation analysis. Step 3: Speed - FOC Correlation analysis Speed - FOC Correlation analysis is depicted once Ship Speed - RPM correlation analysis and FOC-RPM correlation analysis are made. 26
