A submarine detachment of the navy in the eastern theater carried out simulation training close to the actual combat Specialize in refining and improving the ability to deal with special situations Xu Wei and Chen Zesheng reported: "the damage control exercise alarm, a large amount of smoke was found in a cabin." In early spring, a simulated training of navigation damage management was carried out in a submarine detachment of the navy in the eastern theater. At the training site, the submarine that was organizing a deep simulation voyage suddenly lost power, the alarm sounded suddenly, and the smoke filled the whole cabin in an instant. Time is life. The electromechanical chief Wang Peng quickly commanded the crew to seal the cabin and cut off power. Under dim light conditions, the crew passes through the gap of pipeline equipment to determine the ignition point. After some intense operation, the fire was quickly controlled. Since the beginning of the training in the new year, the detachment has carried out special intensive training on damage management skills in combination with shore port simulation navigation training. Aiming at the situation that submarines may encounter when sailing to sea, they simulated the special situations such as power failure and thick smoke under large-depth navigation, set the training environment dangerous and difficult conditions, and tempered the special situation handling ability of officers and soldiers. "New fire found in adjacent cabin!" Wang Peng immediately ordered the closure of the cabin to put out the fire and organized personnel to evacuate. The dim lights and narrow space pose a severe challenge to the crew's emergency disposal. Set up isolation belt and float air supply... In the face of special circumstances, the officers and men of the whole boat operated in an orderly and tense manner. "It takes a long time to seal the cabin"... In the reply, the comments hit the key. In this training, the detachment refined the training standards, improved the operation process, strengthened supervision and inspection, adopted random sampling and other methods to assess and accept the training effect of submarine berthing duty group, improved the damage management training plan, and improved the training quality and efficiency in specializing in refinement.
