Aging Of General Cargo Ships Safe Operation Of The Hull Structure Risk Assessment And Security Technology,

Currently, the global shipping market is in full blossom. No matter the liner shipping, bulk carrier, or the crude oil transportation is in a sound developing period. In the past few years, shipping industry developed rapidly in china. With the more and more fierce competition in international shipping market, many shipping companies are confronting the crucial challenge and life-and-death pressure, second-hand vessel is the first choice, and most is of 15 year old or above.

Currently, the risk analysis work mostly based on the experience of the superintendents, the society's surveyors or the shipyard's specialist, which needed to cope with overcautious.The paper consists of six chapters. The first chapter fully expounds the ship's accidents. The second chapter carries out various analysis of steel. The third chapter analysis the longitudinal strength and local strength.The fourth chapter provides the other factors that influence the safe-sailing of the ships. The fifth discusses the deficiencies inspection and judgement. And the sixth put forward the technical methods for safe guarantee to the aged vessel.
