Why?? Any good reason, other than “I don’t like China, they cheat us by selling thing we want at prices we like”?
The Chinese Shipyards build ship for every serious shipping company in the world today. You want foreign designs to highest standard and complexity and foreign supplied machinery (much of it made in China on license, or by Chinese subsidiaries of foreign manufacturers) to go with it you pay about the same as to build in Korea, Japan, or in Europe.
Come to think of it, isn’t that the same as what the few US shipyards that build commercial vessels do today??
If you can find the equipment list for any of the JA compliant OWF-vessels on order you can confirm that. (No foreign bent plates thought)
PS> Same apply to most newer fishing vessels, OSVs and tankers built at US yards.
