Laytime calculator

Enter the SOF events and the charter party terms to see laytime, demurrage and despatch.

Support calculation. Checking and validating it against the charter party terms is the responsibility of the user.

Everything is calculated in your browser. Nothing you type is sent to the server; the draft stays on this device only.

Port

Sets the time zone and the national, state and municipal holidays.

Fills the terms with common values. Adjust them to your charter party.

Fills in the terms with the form defaults. Everything stays editable; adjust to your C/P clauses.

SOF events

Dates and times in port local time.

Local port time. If blank, the laycan does not limit when counting starts.

Stoppages

No stoppages.

    Charter party terms

    Laytime allowed
    Weekends and holidays
    Laytime commencement

    Only matters when there is a laycan opening and NOR comes before it.

    Tick only if authorised: time then counts even before laycan opens.

    Exceptions by stoppage cause

    How much of the time stopped for each cause is excluded from laytime.

    Adjust by cause (0 changed)
    Advanced rules (multiple ports, berth charter, tanker)

    When off, the calculation follows exactly the previous rules. New rules are pending validation.

    Demurrage / Despatch

    Blank: half the demurrage.
