Hanwha Ocean will build six container ships for Taiwan's Yang Ming Marine Transport. The contract is worth 1,552.7 billion won, about $1.13 billion at the contract-date rate. That equals 12.1% of Hanwha Ocean's FY2025 revenue. Korean rules treat that size as material for a large corporation. Work runs from September 2026 to September 2029. The ships will be delivered in Asia. Hanwha Ocean holds a down payment on signing. It collects the rest as construction progresses. The filing does not break out per-hull pricing or margin. It also gives no delivery schedule for each ship. The company says the final settlement amount can still change.
