NOTE: The output described in this article is for the first simulation run only.

The general accessibility output shows the number of accessible weather windows for each logistic unit for the whole simulation run.

Input variables:

  • Required/reference weather window length
  • Daily operation time (e.g. 7-19) - the general accessibility output disregards the shift time
  • Access limitations from vessel database

For example, the following days the described weather has given:
  • Day 1: whole day wave height < 1.5 m
  • Day 2: whole day wave height < 1.5 m
  • Day 3: until 14:00 wave heigth < 1.5 m
  • Day 4: after 10:00 wave heigth < 1.5 m
  • Day 5: whole day wave height < 1.5 m
  • Day 6: between 09:00 - 17:00 wave heigth > 1.5 m
  • Day 7: whole day wave height < 1.5 m
This information are given from the weather documentation.

Due to this information is defined:
  • Day 1: 24 h accessible
  • Day 2: 24 h accessible
  • Day 3: 14 h accessible
  • Day 4: 14 h accessible
  • Day 5: 24 h accessible
  • Day 6: 12 h accessible
  • Day 7: 24 h accessible
Additionally, the following information is defined:
  • Minimal weather window: 4 hours
  • Shift time: 07:00 - 19:00
Due to this information, an operation on day 6 is not possible.

This can then be calculated:
Day 1 + Day 2 + Day 3 + Day 4 + Day 5 + Day 7 = 6 Accessible days
6 days / 7 days = 0.8571 = 85.71 % Accessible days

CellDescription
Column ADisplays the wind farm name (if no name is provided, "default" is used as standard). 
Column BDisplays the vessel name and ID (the ID is found in the URL when editing the vessel).
Column CDisplays either the number of accessibility days (in the top rows), or the date and time when the vessel requires a weather window.
Column DDisplays the hours of weather window required (used with column C).
