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).
