A local university has completed the installation of a world-class test facility for large-scale models of surface ships and submarines, which the university says could be of much help to the navy.
The test facility, called the Large Cavitation Tunnel (LCT), is the third largest of its kind in the world. Completed earlier this year, it sits in the Keelung-based National Taiwan Ocean University (NTOU). It cost nearly NT$400 million to build and took more than three years to complete.
The university made a detailed introduction to the functions and capabilities of the LCT on Wednesday at the Tenth National Conference on Naval Ship Engineering hosted by the Chung-Cheng Institute of Technology of the military.

"Commercial ship designs do not need to be tested in the LCT. Only military ships will need tests in the LCT, since they must not produce much noise while in operation," Ke said.
The LCT tests are aimed at finding out -- using a one-tenth scale model of a surface ship or submarine design -- the noise level which would be produced by the vessel's propeller or the vortex which would be caused by the hull design of the vessel.
"If the navy is not interested in using the university's LCT for the design of a submarine, it could consider applying it to find out the noise levels or other relevant facts about surface ships already in service," Ke said.
"The domestically-built Cheng Kung-class frigate, for instance, has been short of such data since the design phase. It is really necessary for the navy to start building a data bank for the Cheng Kung-class frigate regarding facts such as the noises that the ship produces during operation," he said.
The university's installation of a world-class LCT marks part of the efforts being made by academic institutions to comply with the government's policy of developing a self-reliant defense industry.
Besides NTOU, the National Taiwan University and National Chen Kung University have also built similar but lower-end test facilities, which the navy could use in its ship-building efforts.
But these efforts might not be appreciated by defense contractors, who prefer to buy mature technologies from abroad rather than domestically-developed ones that need to take time to become reliable.
The state-run China Shipbuilding Corp. (CSBC), which has been bidding to participate in the construction of part of the eight diesel-powered submarines that the US has promised to get for Taiwan, does not think the university's LCT will be of any help to its submarine building project.
A spokesman for the CSBC said the company does not want to start from scratch, since it does not have much time.
"We are now trying to import existing submarine designs from abroad so as to be able to get into the business as early as possible," the company spokesman said.
Environmental groups yesterday filed an appeal with the Executive Yuan, seeking to revoke the environmental impact assessment (EIA) conditionally approved in February for the Hsieh-ho Power Plant’s planned fourth liquefied natural gas (LNG) receiving station off the coast of Keelung. The appeal was filed jointly by the Protect Waimushan Seashore Action Group, the Wild at Heart Legal Defense Association and the Keelung City Taiwan Head Cultural Association, which together held a news conference outside the Executive Yuan in Taipei. Explaining the reasons for the appeal, Wang Hsing-chih (王醒之) of the Protect Waimushan Seashore Action Group said that the EIA failed to address
Taipei on Thursday held urban resilience air raid drills, with residents in one of the exercises’ three “key verification zones” reporting little to no difference compared with previous years, despite government pledges of stricter enforcement. Formerly known as the Wanan exercise, the air raid drills, which concluded yesterday, are now part of the “Urban Resilience Exercise,” which also incorporates the Minan disaster prevention and rescue exercise. In Taipei, the designated key verification zones — where the government said more stringent measures would be enforced — were Songshan (松山), Zhongshan (中山) and Zhongzheng (中正) districts. Air raid sirens sounded at 1:30pm, signaling the
The number of people who reported a same-sex spouse on their income tax increased 1.5-fold from 2020 to 2023, while the overall proportion of taxpayers reporting a spouse decreased by 4.4 percent from 2014 to 2023, Ministry of Finance data showed yesterday. The number of people reporting a spouse on their income tax trended upward from 2014 to 2019, the Department of Statistics said. However, the number decreased in 2020 and 2021, likely due to a drop in marriages during the COVID-19 pandemic and the income of some households falling below the taxable threshold, it said. The number of spousal tax filings rebounded
Labor rights groups yesterday called on the Ministry of Labor to protect migrant workers in Taiwan’s fishing industry, days after CNN reported alleged far-ranging abuses in the sector, including deaths and forced work. The ministry must enforce domestic labor protection laws on Taiwan-owned deep-sea fishing vessels, the Coalition for Human Rights for Migrant Fishers told a news conference outside the ministry in Taipei after presenting a petition to officials. CNN on Sunday reported that Taiwanese seafood giant FCF Co, the owners of the US-based Bumble Bee Foods, committed human rights abuses against migrant fishers, citing Indonesian migrant fishers. The alleged abuses included denying
