The output report contains a breakdown of your case's simulation outputs. Data in the output report is aggregated for every month and year, and the following statistical values are displayed for each time period:
- Average
- Percentiles (P10 to P90)
- Minimum
- Maximum
- Standard Deviation
- Confidence (minimum)
- Confidence (maximum)
Each tab of the report focuses on a specific aspect of the simulation:
- Summary

- Personnel time spent
- Weather downtime
- Task group duration (days)
- Task group end time

Summary tab
This tab contains general information about your case. The table below describes the information in this tab.
| Title | Descriptions |
|---|---|
| Project name | The title of the project/folder where the case is located. |
| Case name | The named assigned to the case upon creation. |
| Case ID | A unique ID automatically generated upon case creation. |
| Case created | Date and time when the case was originally created. |
| Simulation runs | Number of simulation runs. |
| Exported by | Name of the user that exported the output report. |
| Bases | Number of bases in the case. |
| Assets | Number of assets in the case. |
| Logistics | Number of logistics in the case. |
| Project size | The rated power of the turbines multiplied by the number of turbines in the case. |
| Project completion (days) | The duration of the simulation for the net, minimum, and maximum runs and the different p values in days. |
Other tabs
| Tab name | Description |
|---|---|
| Costs | Any costs associated with the case broken down by base, asset, and logistic. |
| Logistics utilization | Number of days a vessel was utilized per month. |
| Logistics transfer utilization | Number of transfers (drop offs and pick ups) conducted by each vessel. |
| Personnel utilization | Number of days personnel were utilized per days available in a given month/year. |
| Personnel time spent | How efficiently personnel time is spent during work hours. Broken down by group, this output shows time spent working against time spent travelling, being picked up, dropped off, and sitting idle in bad weather. |
| Weather downtime | The downtime in hours per logistic. |
| Task group duration (days) | The time taken in days to complete a group of tasks related to an individual asset. This is each task assigned to an asset, e.g., `Assembly` and `Installation`, as carried out across all asset instances. For example, if an asset has 100 instances, there will be task groups of 100 `Assembly` tasks and 100 `Installation` tasks. |
| Task group end time | The date and time at which the task group for an asset was completed. |
| Average task duration (hours) | How long, on average, a task in a task type, e.g., `Installation` has taken on an asset instance. |
| Milestones | Information on the completion of a task on each asset instance. |
| Inventory | A breakdown of inventory changes as handled as part of the Shoreline Inventory Management feature. View component stock changes over time against total stock levels. |
| Weather causes | Contribution to vessel downtime by weather type as a percentage of the total weather downtime. See the weather causes section below for full details. |
| Case bases | Information on the bases added to the case, including location. |
| Case assets | Information on the assets added to the case, including tasks and inventory management. |
| Case logistics | Information on the logistics added to the case, including activity durations and processes. |
| Case personnel | Information on the personnel added to the case. |
| Case strategy | Information on settings used in the Strategy tab of the case. |
Weather causes
Weather causes lets you see what types of weather contributed to vessel downtime as a percentage of the total weather downtime. Use these calculations to establish where vessels with greater environmental tolerance can improve project efficiency.
Weather types include the following:
- Wind speed
- Significant wave height
- Swell wave height
- Wave period
- Zero up crossing period
- Limited by daylight
- Minimum tide
- Minimum visibility
- Current speed
- Limited by lightning
- Time restrictions
Weather limitations apply to vessel process steps. You won’t see weather downtime for CTVs, SOVs, or helicopters, which do not feature processes.How weather causes are calculated
The percentage value you see for each weather type is the vessel downtime in this period caused by the relevant process, step, and weather type divided by the total weather downtime for the vessel throughout the entire simulation.
A period can be any of the following:
- Month
- Year
- Aggregated month
- Full simulation
For example, if there's a 20-percent occurrence of wind speed exceeding the weather limitation during step 1 of process A on vessel X, this contributes to the overall weather-related downtime for that vessel over the entire 10-year simulation period if the simulation years = 10.
If the criteria for multiple weather types are exceeded, downtime is registered for all applicable causes. This is why the total weather cause percentages might exceed 100 percent. In this case, weather types will have overlapped at some points, e.g., there were periods where windspeed and minimum visibility both exceeded the criteria threshold for operations.
Time restrictions
Any time restrictions you have created on your case are counted as a weather type in the weather causes output report tab. If your case includes multiple time restrictions, they are grouped together in the report as a single weather type (TIME_RESTRICTION).
