China's second domestically-made cruise ship successfully completed its 12-day-long sea trial on Wednesday, according to its manufacturer.

During the sea trial, 149 tests were conducted on Adora Flora City to validate key performance indicators. The ship is set to be delivered to operator Adora Cruises ahead of its maiden voyage from Guangzhou on November 22.

"Breaking with industry convention, the vessel completed all verification tasks in a single sea trial, a process that previously required two separate trials over 14 days," according to Chen Jianwei, deputy general manager of China State Shipbuilding Corp's Shanghai Waigaoqiao Shipbuilding Co.

"The progress of the project represents a further improvement compared with the previous vessel. This is also a proof that we have initially acquired the capability to scale up the cruise vessels' construction," said Chen, who is also chief architect of cruise ship project.

According to Chen, the cruise ship has accomplished 98 percent of workload before the sea trial.

An engineering and technical team of 937 professionals from 12 countries were aboard for the trial voyage that began on May 16, during which they comprehensively verified the vessel's quality and reliability.

Regarded as a gigantic engineering project, the construction of the Adora Flora City involves hundreds of systems, more than 20,000 sets of key equipment, over 25 million components and parts, and more than 4,700 kilometers of cables.

Thanks to the full-process digital and intelligent system, overall efficiency improved by 20 percent over the Adora Magic City, China's first domestically-built cruise ship.
