多用途杂货船载运原木沉船安全剖析(国外英文资料) The direction of the wind, flow, waves and surge direction are consistent, made the ships in bad weather suffer no regular forces, and cause a twisting force from different direction. For more than 20 years old ship, especially made in Japan, South Korea, simple and easy shipping, it is hard to endure long waves hit, some weak positions for the hull is easy to rupture and cause the holds water. Long-term loading of the same cargo on the hull For any type of ship, long engaged in the same kind of goods transportation, and cargo weight and volume for a long time to load the same way will be adverse to the local strength of the ship. In terms of the above four ships, is 20 years old, although the regular maintenance, also do regular inspection, but a single form of load for a long time, some parts of the hull of the ship for a long time under the same stress, shear and torsion, the action of forces is bound to cause stress these parts of the fatigue, the local intensity is abate, cause hull cannot find potential hidden trouble. For two chase tank ship, itself strength is weaker than other types of ships, for a long time the same loading, the same route, the internal forces and external forces of relatively greater than the other types of ships. The effect of the log on the deck on the hull Because of the construction of this type of ship, it is unlikely to have the lower cabinet, such as a bulk carrier, to increase the strength. It cant be as strong as a general cargo ship because it has more than one hold. It is more than the container ship that has a strong special feature. The size of the log is larger and cannot be fully utilized. There will be a large number of lost Chambers, especially the upper and sides of the cargo hold. Oversize cargo already, and no strengthen the structure intensity, thousands of tons of pressure in the deck log and hatch covers, cargo hold no, the tolerance is often just the hull plate. Thousands of tons of deck l
