Tow-to-port operations with PBA loss calculations

You can now model tow-to-port operations with advanced precision:

• Compute PBA loss on the remaining WTGs in a string during tow-to-port operations.
• A new toggle in the Corrective Maintenance tab allows you to include or exclude PBA loss calculations across the string based on your modeling preferences.

Logistic lead time inputs for towing vessels

Add lead time durations for towing vessels to model more accurate scheduling and downtime calculations.

Charter starts after vessel's lead time in Design Shoresim.

• Vessel charters now span multiple work orders without requiring lead time resets after each round trip.
• Lead time applies only at the start of the charter period, enabling uninterrupted operations.

Continuous towing in/out modeling

You can now model a scenario where towing vessels towing an asset back to the wind farm can pick up another for MCR during the return trip.

Enable this feature by selecting the new Allow Continuous Disconnection option on towing vessel instances.

• Shoresim now prioritizes available chartered vessels before initiating new charters, reducing redundancy and costs.
• Vessel charters remain active during towing-in and towing-out phases to avoid operational gaps. Enhanced coordination for multiple towing vessels ensures charters end only after their respective operations are complete.
• Towing operation days are calculated only for the period between mobilization and demobilization.
