Frequency distribution of project duration. Shown is the distribution of project duration in days for an installation sequence of 90 tripod foundations in the North Sea starting on 26 October based on 48 simulations using corresponding weather sequences from coastDat-2. The frequency distribution and corresponding estimates of the 5 and 95 percentile are shown in blue. Similarly a fitted Weibull distribution is shown in red. Summary statistics for both distributions are indicated on the right.
