Klebanov never truly let go of the collision theory, saying the sub hit a "huge, heavy object" of "very large tonnage" that tore open the boat's hull. But he offered no suggestions about what that might have been, and there were no reports of a surface ship in the area with severe hull damage...
Officials have talked of attaching floats to the hulk, inflating them and lifting it to the surface. But with much of the hull flooded, the 14,000-ton Kursk could now be a waterlogged 30,000 tons, even more difficult to handle. A chilling but possible alternative is to leave it on the seabed, along with the six other nuclear submarines, four of them Russian, that have sunk in the age of the atom. The double steel hull of the Kursk will provide some containment for the reactors, which are encased in heavy, steel pressure vessels. The submarine would provide...
...hasn't been lost for more than 30 years because of a rigorous certification program that gives each key piece of a submarine--including its hull, pipes, valves and flood barriers--a serial number pinpointing its source and whom to hold accountable if it fails. Critical systems are duplicated. For example, there are three ways to empty the ballast tanks on Trident missile boats. U.S. submarine crews are repeatedly drilled, ashore and afloat, with two key aims: to keep their sub safe and, if that fails, to get out alive. The top concerns for crews include knowing how to restrict...
...accounts, the gamble has already proved worthwhile. For 25 years, the Genmar factory at Little Falls, Minn., has used the same caustic, grubby process to churn out Wellcraft and Glastron fiber-glass runabouts. Men and women in blue coveralls layer or spray fiber glass over each hull. Half-finished boats are scattered around the warehouse, overshadowed by stacks of used molds. The stench of styrene is overpowering. The manual layering process is so imprecise that each hull is different; imperfections have to be corrected by hand...
Every 35 min., each cell produces a new hull; next door it takes eight hours and at least twice as many people to finish one. Each completely recyclable plastic mold produces a dozen boats; next door it takes a mold per boat, and each year thousands of used molds have to be buried in landfills. Each VEC hull is so strong that Genmar has announced a lifetime warranty instead of the normal five years...
