The cargo stowage process in ships consists in arranging items into holds. This paper approaches the problem of finding the maximum number of stowed units of wood pulp into holds of dedicated maritime international ships. This problem, essentially three-dimensional, can be reduced to the two-dimensional case due to constraints provided by the transport and becomes similar to the manufacturer's pallet loading problem. We present in this paper a formulation to the woodpulp stowage solved by a Lagrangean relaxation with clusters (LagClus) that considers the conflict graph generated by overlaps of woodpulp units.
