This article will guide you on how to add and edit a Crane to your case. There are two steps to adding a Crane:

Adding a Crane

1. Open your case and go to  Build → Logistics → +Add 

2. You will then have a selection of logistics that you can add. Click on Crane.

3.  When you select the logistic type you want to add you will be directed to the selection of the cranes in your input library. Just click on the instance you want to add.

4. Complete the necessary information on how the Crane should be used. In this case the number of cranes you will need, shift, homeport, etc.

  • Name: The name of the Crane
  • Number of units to add: How many Crane you will add
  • Port: It is mandatory to add the port. If you have not added a port to your case yet, you will not be able to add the vessel.
  • Lead time (Construction only): Time required to prepare the vessel prior to deployment.
  • Availability: The daily availability of the Crane 
  • Alter vessels settings: Here you can define if the shift time is constant or if it alters. 
    • by date and the settings will repeat annually: This option lets you assign the vessel to only be available within the period you have selected. In the example below, the vessel will be available from January 1st to April 5th each year.
    • periodically and specify durations by number of days: This option lets you assign the number of the days the vessel will be available, at which point, it will be unavailable in the same number of days. In the example below, the vessel will work for 14 days, then have 14 days off, before it starts it's rotation again for 14 days. 

  5. Click on 'Next'. Here you can add all the necessary information or leave as it is and click Add

Editing a crane

1. Go to your Crane and hover your mouse over it and click on it.

2. Add or edit all necessary information. Sections available are:

3. See more detail on each section: 


If you click on Crane 1, you will be able to make adjustments to the information you added when inserting the logistic. This is a shift, availability, port, etc.

Weather Criteria (O&M Only)

  • Wind speed limit crane operation: The maximum wind speed that the crane can do any work 
  • Wind speed limitation reference height: Reference height for the cranes wind speed access limit. You can add the reference height the weather restriction corresponds to in order to extrapolate the wind speed to the same reference height as the weather limitation.
Fuel Consumption 
  • Fuel Unit: Choose between litre or tonne
  • Fuel consumption while moving: The fuel consumption when the crane is in transit 
  • Fuel consumption while working: The fuel consumption when the crane is operating on an asset

In this section, you can define the cost involved with the crane.

Step 1: define the currency 

Step 2: Add any cost you want to report on. Some examples of the cost you can manage are: 

  • Day rate: when it is doing work. Technically when it is not in the state called available in the crane statechart
  • Fuel Cost: The cost is based on the fuel unit, so if the unit is set to litre, the fuel cost will be per litre; if the fuel unit is set to tonne, then the fuel cost will be per tonne. 
    • It is a combination of a lot of different registration that then, in the end, get the total fuel consumption and from that the fuel cost.
      • working - while it is doing repairs - registered from hours
  • Mobilisation cost: It is calculated every time the vessel does a mobilization
  • Port fee: It is calculated every time the vessel moves from the port to another destination

Data Time Series

You can also add a cost time series, so your cost differentiates by year. This is done by clicking on the  Open Time Data Series button.

Set your year range starting with 1 and how many years you want to simulate and click  Update- the actual year is derived from the operational start year on the assets (if your operational start year is set to 2021-xx-xx, year 1 is 2021, year 2 is 2022 etc.), to which you can add the cost per year.

Activity Durations (O&M Only)

  • Mobilising time: The time needed for the crane to mobilise
  • Demobilising time: The time needed for the crane to demobilise
  • Connection time: The time needed for the crane to connect to an asset
  • Disconnection time: The time needed for the crane to disconnect from an asset

Capacity (CON only)

You can bundle multiple work orders on the same crane using the Capacity tab.

Set the capacity of the vessel (i.e., how many tasks it can carry) and the minimum capacity. Minimum used capacity controls how much of the capacity on this transport that needs to be filled before it can leave the base. The minimum waiting time set on tasks will override this parameter.
