摘　　要：在韩国注册的船舶中,总吨不足30的小型船舶约占90%,其中大部分为玻璃钢渔船。为了减少这些小型船舶的温室气体排放,韩国实施了一系列措施,但并没有像IMO MARPOL法规一样强制实行,所以效果并不明显。通过比较韩国玻璃钢渔船设计规范与其他国家船舶设计规范,分析韩国渔船结构设计余量和因设计余量导致的船体建造原材料增加对大气污染的影响,确认船体减重对改善玻璃钢船舶环保性能的可行性。研究结果显示,对于船体结构设计,韩国玻璃钢渔船设计规范,没有考虑纤维含量与积层板力学性能的关系,同时没有考虑船型、结构布置等参数对设计载荷的变化。因此,相比其他国家船舶设计规范,按照韩国玻璃钢渔船设计规范设计的船体结构存在较大的设计余量,会加速全球变暖和臭氧层破坏。Small vessels of GT(gross ton)30 or below account for 90 percent of all registered vessels in Korea,most of which are built from composite materials.Recently several efforts have been made to reduce the amount of greenhouse gas emitted from such small vessels;however,they are mainly ineffective as they are not compulsory like the emission regulations from IMO MARPOL.This study aims to evaluate design margins of Korean composite fishing vessels by comparing the Korean rules on small composite vessel designs to other related international rules.This study also aims to quantitatively show how reducing the design margins can help make small composite vessels more environmentally friendly.This study showed that the Korean rules were not taking into account the fiber weight fraction of composite laminated plate,which determines physical properties of the plate.The Korean rules also failed to consider the effect of hull shape and structural layout on the design load of a vessel.As a result,design margins in Korean rules were slightly larger than that of other international regulations.This difference in design margins was proven to contribute to the global warming and the depletion of ozone layers.
