What reorder point means
The reorder point is the stock level at which a new order should be placed so that parts still arrive before the ship runs out. Lead time at sea is long: a filter or impeller can take weeks from the maker. Safety stock covers delays, extra consumption and a missed port.
How this calculator works
ROP = Daily use × Lead time + Safety stock. If current ROB is entered, the page says whether you are already below the reorder point. Critical class-required spares follow the company’s minimum-stock list, not only this formula. Order quantity is a separate decision.
Who should use it
Useful for the second engineer and storekeeper. Official requisitions stay in the company PMS.
