      • Salary (hourly or annual)

Logistics utilization​

Operation days (total): The number of days the logistic was in operation

Operation days (possible): The percentage of available days that the logistic was in operation:

  • An available day is any day where the logistic is available for operations.
  • Calculation: Operation days (total) / Available days.

Number of flying hours: Helicopter flying hours per month and year.

Logistics transfer utilization​

The transfers conducted by a logistic on each asset.

Possible transfer types:

  • Drop off
  • Pickup

Logistics time spent​

The amount time each logistic spent in different phases of operation, such as Waiting on weather (i.e., downtime), Traveling, or Waiting to be scheduled.

Personnel utilization​

Number of days personnel were utilized per days available in a given month or year.

Aggregated values are derived by adding together the values from all the relevant days in the simulation and dividing by the number of days the personnel were available.

Example​

For a given year of the simulation, we have these values:

  • Personnel in a group: 15
  • Personnel used per day: 5
  • Number of possible workdays: 300
  • Number of non-workdays with weather that would’ve allowed work: 12

Personnel utilization is derived with the following calculations:

  • 5*300 = 1500 working personnel
  • 15*(300+12) = 4680 total personnel available
  • 1500/4500 = 0.3205 = 32.053 percent personnel utilization in the given year of the simulation

Personnel time spent​

How efficiently personnel time is spent during work hours. Broken down by group, this output shows the percentage of time spent working against time spent travelling, being picked up, dropped off, and sitting idle in bad weather.

Weather downtime​

The percentage of time a logistic was available for operations but spent idle due to bad weather. Calculation: Bad weather hours / Available hours

Task group duration (days)​

The time taken in days to complete a group of tasks related to an individual asset. A task group is each task type assigned to an asset—-e.g., Assembly or 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 the average task of each task type, e.g., Installation, took on an asset instance.

Milestones​

Information on task completion on each asset instance.

  • Infrastructure Id: The name and unique ID of the asset instance.
  • Status: The type of milestone.
  • Related work order id: ???
  • Workorder component: The work order ID related to this milestone.
  • Workorder birthtime: When the work order for this milestone was created.
  • simDuration: The amount of time that has passed in the simulation up until this milestone.
  • simDateTime: The date and time in the simulation up until this milestone.

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.

  • Port: The base at which the inventory is stored.
  • Component name: Custom name set at the time of inventory creation.
  • Change: Stock level change that occurred at the registered time. Either + for additional stock or - for removal of stock.
  • Actual stock level: Amount of the component in storage after the change.
  • Time: The simulation time at which the stock change occurred.

Weather causes​

Contribution to logistic downtime by weather type 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
info

Weather limitations apply to vessel process steps. You won’t see weather downtime causes 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).
