Understanding the Simulation Output Dashboard

What is this article about?

After a simulation case has finished running, the Output Dashboard is where you review and interpret the results. This article explains how to navigate the dashboard, what the controls do, what charts and metrics are available, and how to read them — for both Operation & Maintenance (O&M) and Construction simulation types.

Prerequisites

Before you can view output results, the following conditions must be met:

A project and case must already exist in the system.
The simulation must have been started and reached a completed state. Cases that are still running, failed, or have never been submitted will not show output data.
You must have at least read access to the case.

Note: If a chart shows the message "No data available for this output", the selected percentile may not have data, or the case configuration may need to be reviewed. Try adjusting the percentile selector, or check your case inputs and re-run the simulation.

How to Access the Output Dashboard

Open your Project from the project list.
Select the Case you want to review.
Click the Output tab or navigate to the output view for that case.

The dashboard loads automatically once the case is selected.

Dashboard Layout Overview

The output page is divided into the following areas, from top to bottom:

Area	Description
Sticky controls bar	Always visible while scrolling. Contains the output mode toggle (Construction only) and the percentile selector.
Reports	Download links for generated output reports.
Key Metrics	Summary cards with headline figures (statistical mode only).
Construction charts	Charts specific to Construction cases.
O&M charts	Charts specific to Operation & Maintenance cases.

Dashboard Controls

Percentile Selector

The Percentile dropdown (labelled Percentile in the sticky bar) controls which statistical representation of the simulation results is displayed across all charts on the page simultaneously.

Because each simulation case runs multiple times (Monte Carlo runs), the results form a statistical distribution. The percentile selector lets you choose which point on that distribution you want to inspect.

Available options:

Option	What it shows
Average	The mean value across all simulation runs.
Min	The most optimistic result (lowest value).
P10	10% of runs produced a result at or below this value.
P20 – P80	Intermediate percentiles (P20, P25, P30, P40, P50, P60, P70, P75, P80).
P50	The median result — the default selection.
P90	90% of runs produced a result at or below this value. This is typically the most pessimistic realistic estimate.
Max	The highest single result across all runs.
Net Run (Construction only)	Represents the net campaign result rather than a percentile slice. Only available for Construction cases.

Tip: P50 (the default) is the median and is generally a balanced starting point for analysis. Use P10 for optimistic planning and P90 for conservative or risk-informed planning.

When you change the percentile, all charts and key metrics refresh automatically to reflect the new selection.

Output Mode Toggle (Construction Cases Only)

Construction cases have an additional toggle at the very top of the sticky bar that switches between two views:

Mode	What it shows
Statistical	Aggregated results across all simulation runs, driven by the selected percentile. This is the default view.
Run-specific	Results for a single representative simulation run, selected based on the chosen percentile.

When Run-specific mode is active and a task group sort is enabled, additional controls appear:

Run selector – lets you navigate between individual simulation runs.
Task group selector – filters the S-curve and inventory charts to a specific task group.

Note: Switching to Statistical mode or selecting the Net Run percentile will automatically reset the run selector and task group filter.

Key Metrics Panel

The Key Metrics section appears in statistical mode only and displays a set of summary cards that give you a quick, at-a-glance overview of the most important simulation outcomes for the selected percentile.

Metrics are organised into subsections:

Summary (O&M Cases)

Metric	Unit	What it means
TBA Loss	%	Time-Based Availability loss — the percentage of total possible operating time lost to downtime events.
PBA Loss	%	Production-Based Availability loss — the percentage of potential energy production lost due to downtime.
Lost production	MWh	Total energy production lost across the wind farm over the simulation period.
Downtime	Hours	Total accumulated downtime hours across all turbines.
Gross capacity factor	%	Ratio of actual energy produced to the theoretical maximum if the wind farm ran at full rated power continuously.

Personnel Utilization

Grouped by personnel type (e.g., Tech Group). Shows operation days as a percentage of total possible working days for that personnel group.

Logistics Utilization

Grouped by individual logistics unit (vessel or crane, identified by name and ID). For each unit:

Metric	Unit	What it means
Operation days	Days	Number of days the unit was actively used during the simulation.
Possible operation days	%	Operation days as a share of the total days the unit was available according to its availability settings.

Example: A Service Operation Vessel (SOV) with 495 operation days and a 67.7% possible operation days figure means it was active for 68% of the days it could theoretically have worked.

Construction Charts

These charts appear for Construction cases only.

Statistical Mode Charts

Task Group and Average Task Duration

A bar chart showing how long each task group took to complete. Toggle between two views using the selector above the chart:

Total – total duration in days per task group.
Average – average duration per individual task in hours.

Use this chart to compare which task groups are taking the most time and where scheduling efficiencies might be found.

Task Group End Date

A scatter chart showing the completion date for each task group across simulation runs. The X-axis is the date and each task group occupies its own Y position.

Use this chart to assess the spread of completion dates for key milestones and understand schedule risk.

Personnel Time Spent

Shows how time was distributed across personnel groups. A Personnel groups dropdown lets you switch between different personnel categories if multiple are configured. A toggle selector lets you switch between time aggregation views.

Use this to understand how much of your labour resource was consumed and by which activities.

Personnel Utilization

Shows the utilisation rate (as a percentage) for each personnel group — how much of their available time was spent on active tasks.

High utilisation may indicate a personnel bottleneck; low utilisation may indicate over-provisioning.

Weather Downtime (shared with O&M)

See the Weather Downtime Per Logistics Unit and Weather Downtime Causes sections below — these charts appear in Construction statistical output as well.

Run-Specific Mode Charts

Cumulative Tasks Completed (S-Curve)

A line chart (also available as a bar or scatter chart) plotting the cumulative number of completed assets over time for the selected simulation run. The X-axis is the date and the Y-axis is the number of tasks or assets completed.

The S-curve is the primary tool for tracking construction progress. A steep middle section indicates a productive installation period; a flat tail may indicate weather delays or resource constraints near the end of the campaign.

If a task group filter is applied, the S-curve is filtered to show only the tasks within that group.

Inventory Management (feature-dependent)

Tracks parts and component inventory levels over time for the selected simulation run. This chart is only visible if the Inventory Management feature is enabled for your account.

Use this to identify periods of component shortage that may have caused delays.

O&M Charts

These charts appear for Operation & Maintenance cases only.

Production-Based Availability

A line chart showing Production-Based Availability (PBA) over time, plotted per simulation year on the X-axis and as a percentage (0–100%) on the Y-axis.

PBA represents the share of potential energy production that was actually achieved. A value of 100% means no production was lost; lower values indicate downtime-related losses.

This is one of the most important O&M output charts. Use it to track how availability changes year-over-year across the asset lifetime.

PBA Loss Per Root Cause

A breakdown of the total Production-Based Availability loss, categorised by the root cause of each loss event. Typical categories include weather delays, response times, and equipment failures.

Use this chart to identify which factors are the largest contributors to production loss and prioritise mitigation strategies accordingly.

This chart does not support zoom.

Time-Based Availability

Shows Time-Based Availability (TBA) over time, expressed as a percentage. TBA measures the proportion of time the wind farm was available to produce power (regardless of whether the wind was blowing).

TBA is plotted per year and can be broken down by different downtime categories (technical, weather, etc.) depending on data availability.

TBA gives a purely time-based view of downtime. Compare it with PBA to understand whether downtime events are coinciding with high-wind periods (which would show a larger PBA loss than TBA loss).

Scheduled Maintenance Completion Per Year

A bar chart showing the completion rate of scheduled maintenance tasks on an annual basis. The Y-axis is expressed as a percentage (0–100%), and the X-axis represents simulation years.

A completion rate below 100% in a given year indicates that not all scheduled tasks were carried out, which may be due to weather downtime or resource constraints.

Personnel Time Spent

Shows how much time each personnel group spent on active tasks during the O&M simulation, broken down by activity type.

A Personnel groups dropdown lets you filter to a specific group if multiple are configured.

Personnel Utilization

Shows the utilisation rate (percentage of available time actively used) for each personnel group.

Logistics Transfers

Shows the number of transfers or mobilisations made by each logistics unit (vessel or vehicle) over the simulation period.

A high number of transfers for a small vessel alongside low transfer counts for a larger vessel may indicate suboptimal task routing.

Logistics Time Spent

Shows how the operating time of each logistics unit was distributed across different activities or task types.

Logistics Operation Days

Shows the total number of operational days per logistics unit per year. This is the number of days each unit was actively conducting tasks.

Logistics Utilization

Shows the utilisation rate of each logistics unit — i.e., the ratio of actual operation days to the total days the unit was available according to its availability settings.

A vessel with a utilisation rate close to 100% is operating near its capacity limit. A low rate may indicate that the vessel is oversized for the maintenance workload, or that weather downtime is preventing it from being deployed.

Weather Downtime Per Logistics Unit

A chart showing the weather downtime rate for each logistics unit, expressed as a percentage of available hours per period (monthly or yearly, selectable via a toggle).

The yearly view shows total annual weather downtime divided by available hours that year.
The monthly view shows weather downtime per calendar month during the simulation, using actual month-by-month data rather than aggregated averages.

A Vessel dropdown lets you switch between individual logistics units if multiple are configured.

How to read it: 0% means no weather downtime was recorded in that period; 100% means the unit had no usable weather windows at all during that period.

Use the monthly view to identify seasonal weather patterns and their operational impact. Compare vessels to understand which assets are most sensitive to weather.

Weather Downtime Causes

A breakdown of weather downtime by the specific weather condition responsible (e.g., wind speed, wave height, fog, rain). Data is shown per logistics unit.

A Vessel dropdown lets you filter to a specific unit.

Use this chart to understand which weather parameters are the binding constraints for your logistics fleet. This can inform decisions about vessel specifications or operational strategies in future designs.

Downloading Chart Data

Each chart includes a download button that allows you to export the underlying data as a file (e.g., Excel or CSV). The download button appears in the top-right corner of each chart section.

Reports are generated based on the currently selected percentile, so make sure you have the right percentile selected before downloading.
