Hanwha Ocean Co. Ltd.

Hanwha Ocean builds naval frigates and offshore platforms at its Geoje Island facility by welding steel — sourced from POSCO and cut by workers holding Korean marine-welding certifications — into continuous hulls inside dry docks that each hold a single vessel for twelve to twenty-four months at a time. Because the hull cannot be built in stages across separate sites, each dry dock is effectively the production line itself, and the moment a finished vessel is launched is the moment that dock earns the third milestone payment and becomes available for the next keel laying. The total number of operational docks sets a hard ceiling on how many vessels can be built in any year, and adding a new dock takes years, so the order book can grow faster than the facility can physically absorb it. Korean domestic-content and security-clearance regulations require that naval vessels be built at a domestically certified yard, and those certifications are tied to Geoje Island's own audit history, which means the Korean Navy has no legal alternative — though if Seoul were to change those rules, or a typhoon shut the facility long enough to trigger force-majeure clauses, the queue of customers who currently cannot leave would suddenly find they could.
