Stowage plans that follow the port rotation

Every container has a port, a weight and a place in the stack. Our models plan the stowage with port order, weight and stability solved at once: last port at the bottom, first port on top, heavy containers low. The ship sails full, sits level, and at every port the right containers are on top.

The problem

Every restow is a crane move you pay for twice

Stowage is often planned under time pressure, stack by stack, with port order, weight and stability checked one after the other. Containers for an early port end up under cargo for later ports, and heavy boxes end up high. At the next port the cranes dig: lift, park on the quay or in another bay, and lift again.

It costs crane moves and berth time at every port, longer turnarounds, ships that sail below capacity when planners play it safe, and stability margins that are hard to see in advance.

Restows at every port

Containers for the current port sit under cargo for later ports, so the crane lifts, parks and reloads before the real work starts.

Weight in the wrong place

Heavy containers stowed high or unevenly cost stability and trim, and correcting it late means reworking the plan.

Space traded for safety

Loading port by port with gaps keeps every box in reach, but the ship sails part-empty and the rest of the cargo waits for another sailing.

How we solve it

Port order, weight and stability, solved at once

We compute the stowage plan for the whole voyage: which container goes in which bay, row and tier, given every port it calls at and every limit the ship has to respect.

What goes in

  • The port rotation and the containers for each port
  • Container weights, sizes and types, including special cargo
  • The ship's bay layout and stack weight limits
  • Containers already on board from earlier ports

Constraints handled

  • Port order: the next port on top, later ports below
  • Stack weights, with heavy containers stowed low
  • Stability and trim within the ship's limits
  • Rules for special cargo and segregation

What the planner sees

  • A stowage plan per bay, row and tier
  • Expected restows and crane moves per port, side by side with the current plan
  • Weight distribution and trim, before the first box is lifted
  • Containers that cannot be stowed within the rules, named up front
Results

Measured on your voyages, not promised up front

We do not quote restow or turnaround figures before we have seen your cargo and rotations. In a shadow run, our stowage plans run beside your current planning on the same voyages, and you compare the numbers that matter to your operation.

These are the measures a shadow run compares. Outcomes depend on your ships, rotations, cargo and data, and are not guaranteed.
