The Pre-analysis tab is intended for charterers, as a tool to evaluate performance of a ship that they are considering to hire in.
The information is based on AIS data, as well as data entered in the Information section.
Click the date filter, to choose the time period for the analysis:
- Last week
- Last month
- Last 3 months
- Last year
- Dry dock until today (if dry dock date has been entered the Information section)
Alerts are given in the top right corner. The following types of alerts can be given:
- Missing information. If information has not been entered in the Information section but can add value to the analysis. For example, if date of last dry dock has not been entered.
- Incorrect information. If information has been entered in the Information section but that entry has been determined to be incorrect. For example, if last dry dock date is in the future.
- Insights from Ankeri. If results from the analysis suggests that the charterer should inspect further some points, such as if the ship is due in dry dock in the upcoming year or if she has been idle for a significant amount of time.
- Missing or empty data. If AIS data is not available or gives empty results.
The timeline lists the key milestones for the ship in terms of dates of when she was built and last and next dry docks, giving a quick overview of the ship's docking history.
The timeline is based on data from the Information section. Hover over the icons to get more details about these respective events. For example, the build yard when hovering over the ship built icon.
If the ship built year and dates of last and next dry docks have not been entered then the respective icons are shown with a grey colour. Furthermore, this also results in that the timeline cannot be generated and the icons are evenly spread across the timeline. If the date of the next dry dock has not been entered, but the date of the last dry dock has been entered, then the date of the next dry dock is assumed to be 5 years later.
The map shows the historical position of the ship with an orange path. It also shows first position with a star icon and the current position and course shown with an arrow icon. Click the icons to get additional information, such as the current speed and draft. If applicable, the map also shows the port visits with blue circles and idle time locations with red circles.
On the left side of the map there are zoom options. This includes traditional zoom in and out options (can also be enabled/disable by clicking the map and using the scroll wheel on your mouse). Also included are options for full screen mode and default, previous and next zoom modes.
On the right side of the map there is an option to enable a nautical chart from OpenSeaMap. Please note that this option is only available with sufficient zooming on the map.
This table list the port visits, with information on time moored and cast off. Click the eye icon to show and hide the port on the map. If the port coordinates (latitude and longitude) are not available in Ankeri, then the eye is shown with a grey colour.
The total number of port visits are shown in the right corner.
Please note that the port visits can currently only be gathered for the last week or month (not more than one month).
Port names, countries, coordinates and codes are taken from UNECE. If coordinates are missing, please submit a request.
This chart shows the speed profile in a histogram. The speed values are shown on the x-axis and the time spent is shown on the right y-axis. Click the percentage icon to toggle this axis to days instead of percentages.
The chart can also show consumption data from the Information section on the left y-axis:
- Speed-consumption curves for design and scantling drafts
- MCR consumption based on main engine MCR and a fixed specific fuel oil consumption of 180 g/kWh.
The average active speed, is the average speed only considering speeds above 5 knots and is shown in the top right corner.
This chart shows the ship's trade areas. This is given in terms of the active and inactive time, where active denotes the case where the vessel is sailing at speeds above 5 knots. Click the percentage icon to toggle the axis to days instead of percentages.
The number of trade areas and the proportion of time where the the vessel is active is shown above the chart.
This table gives an overview of the idle times, in terms of the area, start date and idle time duration. Please note that ongoing idles times are not shown, only past idle times. Click the eye icon to show and hide the idle times on the map.
The total idle duration and number of idle time periods is shown above the table.
The following criteria is for an idle time period in Ankeri:
- Idle time period needs to be at least 48 hours.
- Vessel cannot sail at more than 6 knots continuously for 3 hours.
- Vessel cannot cannot sail more than 40 nm from start of idle period.
Please note that the sea temperature for the idle times is not available yet in Ankeri.
