Nine years on, J.Ocean Heavy revives Gunsan shipyard as major production hub

The Gunsan shipyard in North Jeolla Province, which struggled through years of industry downturns and order droughts after its completion in 2010, is now moving quickly to restore full shipbuilding operations under its new owner, J.Ocean Heavy Industries. Despite housing the world's largest single dry dock, the yard sat idle for nine years in terms of completed-vessel production amid a prolonged industry slump, leaving it a symbol of the region's economic pain.

J.Ocean Heavy Industries and HD Hyundai Heavy signed a deal last month to transfer ownership of the Gunsan shipyard for 780 billion won ($523 million), according to industry sources Thursday. Payment and the formal transfer of title are expected to be completed by year-end. J.Ocean Heavy Industries is a corporate entity created by EcoPrime Marine Pacific — the private equity fund that is the largest shareholder of HJ Shipbuilding & Construction — specifically to operate the Gunsan shipyard.

Since its completion in 2010, the Gunsan shipyard generated annual sales of around 1 trillion won in its early years of operation. A wave of low-cost orders from Chinese shipbuilders and a global decline in new orders sent utilization rates plummeting, and the yard halted operations in 2017. It resumed limited activity after 2022, mainly producing ship blocks. An industry official said J.Ocean Heavy Industries already has a sales team in place and active, and is expected to move ahead with equipment maintenance and a broader hiring push at the shipyard.

The deal reflects a convergence of mutual interests. HD Hyundai Heavy gains capital it can reinvest in future projects or global expansion, while J.Ocean Heavy Industries acquires in one move the infrastructure needed to build very large vessels.

In the near term, the Gunsan shipyard plans to continue producing ship blocks for HD Hyundai Heavy. At the same time, it is refurbishing production facilities with the goal of entering full production next year and delivering its first completed vessel in 2028. J.Ocean Heavy Industries has already secured orders ahead of the formal acquisition closing. Late last month, it signed a letter of intent with an Oceania-based shipowner for four 114,000-ton crude and petroleum product carriers. If the deal proceeds to a full contract, it would mark the first completed-vessel production at Gunsan in nine years.

The local community has welcomed the shipyard's revival. When a yard builds complete vessels rather than components, the utilization rates of hundreds of local parts suppliers and equipment manufacturers rise sharply, setting off a virtuous cycle across the regional shipbuilding ecosystem. The recovery is also expected to stimulate the steel and components industries and generate ripple effects in shipping and logistics.

With the global shipbuilding industry suffering from a shortage of dry-dock slots, the Gunsan shipyard — which carries an empty order book — is well positioned to offer shipowners fast delivery as a key selling point. The yard is equipped with a 1.3-million-ton dock, the world's largest single dock at 700 meters long and 115 meters wide, a 1,650-ton Goliath crane and a 1.4-kilometer quay wall. Its annual assembly capacity stands at 250,000 tons, enough to build 12 vessels based on a 180,000-ton bulk carrier standard. The dock alone surpasses those at HD Hyundai Heavy's Ulsan headquarters (642 meters) and Samsung Heavy Industries' Geoje shipyard (640 meters).

The acquisition is also expected to accelerate a dual-production strategy with HJ Shipbuilding & Construction and generate synergies between the two yards. HJ Shipbuilding & Construction had been unable to take orders for large vessels due to site and dock size constraints, but the Gunsan yard can accommodate very large crude carriers and other oversized ships. An HJ Shipbuilding & Construction official said the company's Yeongdo shipyard will focus on naval vessels and other special-purpose ships as well as eco-friendly container ships, while the new Gunsan yard will serve as a production base for large merchant vessels such as VLCCs and tankers, along with offshore wind structures.

In a recent report, DS Investment & Securities said that because global VLCC slots are already filling up through 2030 deliveries and freight rates remain solid, J.Ocean Heavy Industries can expect strong buyer inquiries if it offers short-lead-time slots for 2028–2029 delivery at premium vessel prices. The brokerage added that HD Hyundai Heavy has contractually committed to placing ship-block orders at the Gunsan yard for the next three years to maintain utilization rates, which should minimize any near-term revenue gap.
