![]() Two minutes and fifteen seconds later, another five to seven torpedo warheads exploded. The torpedo manufacturer challenged this hypothesis, insisting that its design would prevent the kind of event described. ![]() The explosion blew off both the inner and outer tube doors, ignited a fire, destroyed the bulkhead between the first and second compartments, damaged the control room in the second compartment, and incapacitated or killed the torpedo room and control-room crew. Two days later, British and Norwegian divers finally opened a hatch to the escape trunk in the boat's flooded ninth compartment, but found no survivors.Īn official investigation concluded that when the crew loaded a dummy 65–76 "Kit" torpedo, a faulty weld in its casing leaked high-test peroxide (HTP) inside the torpedo tube, initiating a catalytic explosion. President Vladimir Putin initially continued his vacation at a seaside resort and only authorised the Russian Navy to accept British and Norwegian assistance after five days had passed. Officials misled and manipulated the public and news media, and refused help from other countries' ships nearby. Its response was criticised as slow and inept. ![]() Over four days, the Russian Navy repeatedly failed in its attempts to attach four different diving bells and submersibles to the escape hatch of the submarine. The submarine's emergency rescue buoy had been intentionally disabled during an earlier mission and it took more than 16 hours to locate the sunken boat. The crews of nearby ships felt the initial explosion and a second, much larger, explosion, but the Russian Navy did not realise that an accident had occurred and did not initiate a search for the sub for over six hours. The nuclear-powered Project 949A Antey ( Oscar II class) submarine Kursk (Russian: Project 949A Антей Atomnaya Podvodnaya Lodka "Kursk" (APL "Kursk")) sank in an accident on 12 August 2000 in the Barents Sea, during the first major Russian naval exercise in more than 10 years, and all 118 personnel on board were killed. ![]() Loss of the boat, crew, headquarters personnel FOSM method is also used, which greatly under-estimates the failure probabilities for the problem studied in this paper.11:29:34 a.m. SUBSMARINE CRACK CRACKThe influence of crack model uncertainty is significant. From the studies in this paper, it is concluded that the most dangerous case is that the crack is perpendicular to the tension stress. The results obtained from the present method are compared with those obtained from direct Monte Carlo simulations. A simple procedure is presented, in which the Monte Carlo method is used to estimate the bending stress distribution, and an analytical method is used to estimate the fracture failure probability. SUBSMARINE CRACK CRACKEDThe failure of a cracked submarine pipeline subjected to the underwater explosion shock is probabilistically analyzed in this paper. Journal of Offshore Mechanics and Arctic Engineering 123 (3) : 134-140. Probabilistic failure of a cracked submarine pipeline subjected to the underwater shock. ![]() Probabilistic failure of a cracked submarine pipeline subjected to the underwater shock ![]()
