On floating wind farm installation projects, support vessels work alongside a large installation vessel to carry out the station-keeping and hookup of a floating turbine.

In Shoreline Design, you can model this scenario using an HLV as the installation vessel and a feeder vessel as the support vessel.

You will need a case set up with a base, WTGs, an HLV, and a feeder vessel.

Configure your HLV

1. Click on the Build tab.
2. Click on the Logistics tab.
3. Click on your heavy lift vessel.
4. Click on the Processes tab.
5. Click on 5.0 - Working with feeder.
6. Set a Duration that meets the time required for station-keeping, i.e., anchoring and mooring, operations (~11 hours).
   
7. Click on 6.0 - Install component.
8. Set a Duration that meets the time required for hookup operations (~32 hours).
9. Click Save.

Configure your feeder vessel

1. Click on the Build tab.
2. Click on the Logistics tab.
3. Click on your feeder vessel.
4. Click on the Processes tab.
5. Set Duration values on 1.0 - Mobilization, 2.0 - Loadout, and 5.0 - Demobilization.
6. Click Save.

Configure asset tasks

1. Click on the Build tab.
2. Click on the Assets tab.
