CLNG是液化天然气（LNG）加注船的缩写。LNG是一种清洁、高效的能源，由于其运输和储存条件的要求较高，通常需要使用专门的运输船进行运输和加注。CLNG就是专门用于加注LNG的船只，它们可以在海上将LNG运输到其他船只或岸上设施中进行加注，为大型LNG运输船提供燃料。

CLNG船只具有较高的技术含量和安全性要求。由于LNG的储存温度极低，且易燃易爆，因此CLNG船必须具备严格的保温、防火、防爆等安全措施。此外，CLNG船还需要配备先进的加注系统和计量设备，以确保加注过程的安全和准确性。

随着全球能源结构的调整和清洁能源的推广，LNG的需求量不断增加。CLNG船作为LNG供应链中的重要环节，在海上运输和加注LNG方面发挥着越来越重要的作用。目前，全球范围内已经有多个CLNG船队在运营中，为大型LNG运输船提供服务。

英文：

CLNG is the abbreviation of LNG bunkering vessel. LNG is a clean and efficient energy source, but its transportation and storage requirements are relatively high, so it usually requires special ships for transportation and bunkering. CLNG is a dedicated ship for bunkering LNG, which can transport LNG by sea to other ships or onshore facilities for bunkering, providing fuel for large LNG tankers.

CLNG ships have high technical content and safety requirements. Due to the low temperature of LNG storage and its flammability and explosibility, CLNG ships must have strict safety measures such as heat preservation, fire prevention, and explosion prevention. In addition, CLNG ships also need to be equipped with advanced bunkering systems and measuring equipment to ensure the safety and accuracy of the bunkering process.

With the adjustment of global energy structure and promotion of clean energy, the demand for LNG is constantly increasing. CLNG ships, as an important part of the LNG supply chain, are playing an increasingly important role in sea transportation and bunkering of LNG. Currently, multiple CLNG fleets are already in operation worldwide, providing services for large LNG tankers.
