Award N°1139 – Gencon c/p – Notice of readiness – NOR regularly tendered (Yes) – Laytime – Time not to count – Holds rightly rejected because of the specific characteristics of the cargo – Demurrage – Time counting. Since the NOR was tendered by the Master from roads in accordance with c-p terms, time started counting on the same day and not, as alleged by the charterer, at the time loading operations began. Laytime has been interrupted from the time holds were rejected until they were definitely accepted for loading. Bulk ammonium nitrate and urea both require that holds must be dry and absolutely clean prior to commence loading, and these requirements should have been known by the owner.
