船舶运输的主要性能有哪些特点呢？
船舶运输是全球贸易中最重要的运输方式之一，它具有以下几个特点：
1.经济性
船舶运输的经济性是其最显著的特点之一。由于船舶的装载量大，且运输速度较慢，每吨货物的运输成本较低，因此在远距离大运量货物运输中，船舶运输是经济效益最优的选择。
2.适应性强
船舶的载重能力、航速和航程等方面可以根据不同的需求进行调整和改变，因此船舶运输非常适应性强，可以适应不同货物、不同航线以及不同的海况等。而且在繁忙的港口地区和海上交通干线上，船舶的流量大，可随时进行协调调配，优化运输布局。
3.环保性好
船舶运输的环保性在当前全球环保高度重视的时代显得异常重要。相比较其他交通方式，船舶运输对于空气和水质的污染程度相对较低，因为燃料消耗少，有些船舶还可以使用环保燃料。而且，船舶可以通过拦截器等装置对于垃圾、污水等废弃物进行清理和处理，因此能够有效的保护海洋环境的安全性与健康性。
4.不受天气限制
相比较其他交通方式，船舶运输的不受天气限制特点非常突出。尤其是在海洋运输中，因为海洋上气象变化多，所以对于其他运输方式而言，容易受天气影响不能运作，而船舶可以通过应对各种海况和恶劣天气，在海上面对挑战与困难，维护运输的正常进行。
总结来说，船舶运输经济性好、适应性强、环保性佳、不受天气限制，因此是重要的贸易运输方式之一。
关于“船舶运输的主要性能有哪些特点呢？”的英文翻译What are the main performance characteristics of maritime transport?
Maritime transport is one of the most important transportation methods in global trade, which has the following characteristics:
1.Economic
The economy of maritime transport is one of its most significant characteristics. Due to the large loading capacity of ships and the slower transport speed, the transportation cost per ton of goods is low. Therefore, in long-distance and large-quantity goods transportation, maritime transport is the most cost-effective option.
2.Strong adaptability
The carrying capacity, speed, and range of ships can be adjusted and changed according to different needs, so maritime transport is very adaptable and can adapt to different goods, different routes, and different sea conditions. Moreover, in busy port areas and on major sea traffic routes, ships have a large flow, can be coordinated and allocated at any time, and optimize transportation layout.
3.Environmental protection
The environmental protection of maritime transport is particularly important in the current era of global high environmental protection. Compared with other transportation methods, maritime transport has relatively low air and water pollution levels because of less fuel consumption, and some ships can also use environmental protection fuels. In addition, through interceptors and other devices, ships can clean and treat waste, sewage, and other waste, thus effectively protecting the safety and health of marine environment.
4. Not affected by weather conditions
Compared with other transportation methods, the characteristic of not being affected by weather conditions is particularly prominent in maritime transport. Especially in maritime transport, because of the changeable weather on the sea, it is easy for other transportation methods to be affected by weather and cannot operate. Ships can face challenges and difficulties on the sea by responding to various sea conditions and adverse weather, to maintain the normal operation of transportation.
In summary, maritime transport is an important trade transportation method with good economic performance, strong adaptability, good environmental protection, and not affected by weather conditions.
