The surface power plant containment hulls selected for study were unmanned, double-hull, thick- disc, surface-following steel structures of modular construction. Three basic hull designs were established for the five power levels selected for the study program. The hulls are not space limited and, therefore, eliminate arrangement problems. Snorkel systems are included with all hull designs. IVlodular construction permits the complete interchange of machinery space to eliminate at-sea overhaul and increase reliability. A typical configu- ration of a thick-disc hull for a surface power plant is illustrated in Figure 6. The hulls selected have been scaled to approximately the same proportions as the dimensions of the General Dynamic monster buoy.* Since the structural design is available, the thick-disc hull would provide optimum performance at minimum cost. Table 7 summarizes all the characteristics of the thick-disc hull. Machinery weight, hull weight, reserve buoyancy capacity, usable interior volume, fuel storage and trim system capacities, hull characteristics, and typical fuel replenishment are all defined in the table. The reserve buoyancy capacity for larger plants was reduced to allow for a larger on-board fuel supply. This added fuel supply would provide a more reasonable refueling cycle for the larger plants. All surface hulls were sized to carry an adclitional 50,000-pound external load imposed by the underwater transmission cable. The trim system was sized to compensate for variations of the external load. A welded, double-hull construction from low carbon steel was recommended for the surface hulls. The external skin should be fabricated from 1/4-inch plate of higher strength steel. An entrance hatch, air intake and exhaust stacks, navigational lights, and radio antenna would be supported or contained
