In nautical terminology, stowage is the amount of room available for stowing materials aboard a ship, tank or an airplane. In container shipping, stowage planning refers to the arrangement of containers on board a container vessel. The stowage of a container ship involves different objectives, such as to optimize the available space and prevent damage to the goods, and more importantly, to minimize the time the vessel spends at the port terminal. Containers will be arranged depending on their destinations (those going to the first port calls in the schedule will be placed on top), cargo weight (lighter containers are stored on top of heavier ones), cargo nature (dangerous goods containers normally are placed at the end of ship, and on upper deck to minimize the loss, in case of fire or leakage), etc.

First, the expected deck stacking and lashing scheme is determined based on mainstream design, the shipowner's specific requirements, and the need for scheme balance. Then, calculation parameters are obtained based on the expected deck stacking and lashing scheme. These parameters are then input into lashing calculation software for calculation, and the reliability of the deck stacking and lashing scheme is assessed based on the calculation results to determine if adjustments are needed. Finally, schemes deemed unreliable are continuously subjected to "adjustment-calculation-evaluation-re-adjustment" until both deck stacking and lashing schemes are reliable. Through accurate reliability assessment and closed-loop adjustment of the deck stacking and lashing schemes, the final scheme is continuously optimized, resulting in a deck stacking and lashing scheme that is suitable for the ship type, safe, reliable, and meets expectations, thereby avoiding problems such as deck stacking weight reduction and lashing failure during actual operation.
