The first PetroChina 174,000cbm LNG Carrier built by Hudong Zhonghua finished a trial voyage

At noon on August 23, accompanied by a loud whistle, the 174,000cbm LNG carrier H1831A, the first PetroChina LNG carrier built by Hudong Zhonghua, made a triumphant trial voyage and safely docked at Changxing No. 0 base wharf. It took five and a half days to complete the trial voyage ahead of schedule the task and lay a solid foundation for the subsequent gas trial and delivery.

The ship is the first 174,000cbm large-scale LNG carrier manufactured by Hudong Zhonghua Shipbuilding for PetroChina and COSCO Shipping to expand the LNG industry. It is an upgraded and optimized LNG carrier based on the company’s self-designed fourth-generation XDF dual-fuel propulsion. The latest generation of LNG carriers has reached the world-class level in terms of technical performance, environmental protection indicators, and reliability requirements.

The ship is the first ship with many overall projects and engine projects, and all have to test the dual-engine mode and the left-right single-engine mode. If the test is carried out step by step, it will take a long time. With the full support of the ship owner and ship inspection, the LNG project team integrated the resources of the design institute, the quality assurance department, the supporting department, and other departments to formulate a plan carefully, laying a solid foundation for the orderly advancement of the sea trial project. During the sea trial, the sea trial leading group sorted out the key points of the sea trial project according to the sea conditions and the actual situation, constantly adjusted and optimized the plan, and “merged” the projects with similar test requirements to further improve the test efficiency and ensure that the sea trial task was completed on schedule.

The sea trial was successfully completed, and the project team members worked non-stop in the intense terminal cooling test and went all out to make preliminary preparations for the gas trial in early September.

仅用5天半！沪东中华中石油LNG项目首制船试航凯旋

8月23日中午，伴随着一声洪亮的汽笛声，沪东中华建造的中石油国事首制船17.4万方液化天然气船H1831A试航凯旋，安全停靠长兴零号基地码头，耗时五天半提前完成试航任务，为后续气体试航及交船打下坚实基础。

该船是沪东中华造船为中国石油、中远海运拓展LNG产业发展制造的首艘17.4万方大型LNG运输船，是公司在自主设计的全球第四代XDF双燃料推进LNG船基础上，升级优化的最新一代LNG运输船，无论技术性能、环保指标，还是可靠性要求，均达到世界一流水平。

该船是首制船，总体项目和轮机项目较多，而且均要试验双机模式、左右单机模式，若按部就班逐个项目试验，耗时较长。在船东、船检的全力支持下，LNG项目组整合设计所、质保部、配套部等部门资源，精心制订方案，为试航项目有序推进打下坚实基础。在海试期间，试航领导小组根据海况和实际情况，梳理试航项目关键点，不断调整优化计划，将试验要求相近的项目“合并”试验，进一步提高试验效率，确保试航任务按期完成。

本次试航圆满结束，项目组人员马不停蹄投入紧张的码头冷却试验中，全力以赴为9月初的气体试航做好前期准备工作。
