此外，海事部门还组织设立LNG、甲醇、氢燃料和电池动力四类新能源船舶"见习点"，破解船员实操经 验不足的问题；引入智慧教室、VR虚拟仿真系统等实训设备，实现理论教学与实景操作无缝衔接，培 训效率提升60%。 在建造质量监管方面，长江海事局参与编写、起草了新能源(LNG燃料)船舶建造检验和监督工作指南， 为船舶建造提供技术标准。在现场安全监管方面，制定出台了电池动力船舶现场检查指南，并起草了 LNG、甲醇燃料船舶现场检查指南，确保监管有据可依。 随着新能源船舶迅猛发展，船员短缺问题逐渐凸显。针对船员对新能源船舶"不会开、不会管"的难题， 长江海事部门牵头修订《内河船舶船员特殊培训合格证签发管理办法》，增加内河新能源船舶船员相关 内容，并编制内河新能源船舶船员培训大纲。 同时，长江海事局在武汉正式运行长江干线首个新能源船舶联合培训基地，打造"理论教学—模拟实训 —实船操作—就业服务"于一体的全链条培养体系，年培训能力可达2000人次。 记者从交通运输部长江海事局获悉，截至9月10日，长江干线建成投运新能源船舶156艘，同比增长翻 番。预计2025年长江沿线船厂拟建成新能源船舶422艘，未来五年新增建造意向966艘 ...

Group 1 - South Korea has a developed steel industry and has been the largest shipbuilding exporter for a long time, particularly strong in the LNG ship sector with multiple related patents [1] - The election of Lee Jae-myung as the new president of South Korea comes at a critical time, as he immediately assumes office due to a previous presidential vacancy [1] - The U.S. has imposed a 50% tariff on imported steel products from South Korea, which is seen as a severe blow to the South Korean steel industry and its exports to the U.S. market [3][5] Group 2 - The 50% tariff on steel imports will significantly impact South Korea's economy, which already faces unprecedented challenges, particularly due to competition from China [5] - The U.S. is not only imposing tariffs on steel but also on automobiles and auto parts, further complicating South Korea's economic situation [5] - The U.S. strategy towards its allies, including South Korea, indicates that it will exert considerable pressure to force concessions, reflecting a tough stance even against allies [8][10]
