Hanwha Ocean targets US Navy orders as Trump seeks shipbuilding ties

Transplanting processes

Hanwha Ocean's Philadelphia Shipyard is trying to get a licence that clears it to build US Navy vessels, but transplanting cutting-edge manufacturing processes honed from competition with other South Korean and Chinese shipyards is not as simple as bringing in some automated welding machines, Jeong said.

"I think the US shipbuilding industry hasn't had to compete very much. Facilities are old, and there's a shortage of technicians," Jeong said.

"We are looking to modernise facilities, train and equip workers, and bring in our manufacturing process that can build the same ship in, I think, two-thirds the time or less as that of a US shipyard."

Jeong said the company is investing in South Korea to use existing facilities and expand naval ship capacity to build five submarines and three surface vessels at the same time by 2029, from two submarines and two surface vessels now.
