AI Extracts & Reviews Terms

Laytime allowance (e.g. 72 hours SHINC)

Demurrage & despatch rates

Time exceptions (holidays, weekends, weather, etc.)

NOR requirements, commencement rules, and special clauses

Calculation Runs Automatically

Once you confirm the terms, the engine calculates laytime used vs allowed across all port operations:

Applies time exceptions and non-counting periods

Handles reversible laytime, OODAOD, and multi-port scenarios
