As an example the laycan for a ship on a Gencon 76 may have been agreed as Wednesday 8th April – Tuesday 14th April. The time to count from 1400 if NOR delivered in office hours before noon and 0800 the next day if delivered after noon. A rate of 5,000 tonnes per day WP was agreed for cargo handling. Had the ship arrived on Wednesday 8th at 0745, the NOR would have been tendered at 0900 and time and time started to count from 1400 that day. But if the ship arrived on Friday 3rd April at 1100 and tendered immediate notice time would start to count at 1400 on Friday 3rd. None of the time up to 0001 on Wednesday 8th would count either because it was a weekend (excepted under the terms of the c/p) or because the time was before commencement of laydays. But as soon as Wednesday 8th arrived the laytime clock would start to run, and unless the weather prevented any work it would do say at 0001. A whole 14 hours earlier than the charterer may have counted on. Some charterers have countered this advantage for the owner by demanding a clause that prevents the NOR being presented before laydays. INTERRUPTIONS: Once laytime has commenced, unless a vessel’s cargo-handling equipment breaks down, it will continue unhindered until the completion of cargo operations, or until laytime expires or demurrage commences. Nevertheless, contracts frequently include express clauses interrupting laytime in the event of: Weekends and holidays. Shifting between berths. Strikes. Bad weather. Breakdowns. Weekends and holidays: If these are to interrupt laytime, the contract can be said to be on ‘SHEX’ terms (Sundays and Holidays Excepted), or on FHEX terms (Fridays and Holidays Excepted) if in Moslem countries. Should weekends and holidays count as laytime, the contract can be said to be based on SHINC (Sundays and Holidays Inclusive) – FHINC in Moslem countries. The terms SHEX and SHINC came into use when Saturdays were considered part of the working week. Nowadays of course Saturday is also a non-working day and the terms have been altered slightly to SSHEX and SSHINC – sometimes brokers refer to this as ‘full’ SHEX or SHINC as the case may be when talking to each other.
