The main factors affecting the cost of the project of manufacturing buoyancy materials based on spheroplastics have been identified and analyzed; the materials are intended for various production volumes and different hydrostatic strength. On the basis of these factors, a mathematical model is developed to determine the most cost-effective operation modes of the enterprise producing buoyancy blocks from spheroplastics. It is revealed that the cost of production of the buoyancy materials for shallow depths is only slightly dependent on the depth. Therefore, it is impractical to orient the project of production of buoyancy materials at the operating depths of underwater equipment if they are less than 1 km. The study indicates the presence of the optimal production volume of buoyancy materials, reduction of which is accompanied by a substantial increase of the cost of the finished products, and it does not lead to a considerable reduction in price. It is determined that the optimal monthly production volume depends on the operating depths of underwater equipment and varies from 12 m³ for depths less than 1 km, up to 8 m³ at depths of 5 km. When making decision on the order execution, this allows the project manager to agree with the customer upon the economically feasible minimum volumes of the ordered buoyancy materials and avoid execution of unprofitable orders at the stage of their receipt without time-consuming preliminary calculations.
