Dong Fang Offshore Co.

What Dong Fang Offshore Co. does

Dong Fang Offshore Co., Ltd. (DFO, stock code 7786.TWO) is a Taiwan-based marine engineering services company founded in 2019 that operates the country's largest offshore wind support vessel fleet. The company provides full life-cycle offshore wind farm services—from survey, construction support, and submarine cable installation through long-term operations and maintenance—using a fleet of 18 vessels (14 operational, 4 under construction) ranging from 27m crew transfer vessels (CTVs) to a 130m cable-laying ship (Orient Adventurer). Technical capabilities include DP2/DP3 dynamic positioning, a 5,000-ton cable carousel capable of laying over 100km of submarine cable, a 3,000m work-class ROV, 250-ton active heave-compensated cranes, and Taiwan's first local Walk-to-Work motion-compensated gangway system.

DFO's revenue model rests on four streams: (1) long-term vessel charter contracts (12-15 years) for Service Operations Vessels (SOVs) and CTVs to offshore wind developers; (2) submarine cable installation, burial, maintenance, and turnkey telecom cable EPCI projects; (3) offshore wind farm O&M services including balance of plant management; and (4) vessel management services. Customer concentration is anchored on major international developers (Vestas, CIP/Copenhagen Infrastructure Partners, Ørsted-adjacent projects), the Norwegian subsea contractor DeepOcean (European market entry), Chunghwa Telecom (telecom cable EPCI), and emerging Australian partner GO Offshore. DFO secured a NT$2.58 billion (~US$80M) submarine cable EPCI contract with Chunghwa Telecom and a NT$4.6 billion (~US$144M) syndicated loan in September 2025—the largest offshore wind vessel financing in Taiwan. The company was originally incubated by Hung Hua Construction Co., Ltd. (now 39.48% shareholder), listed on the Emerging Stock Board in 2024, and submitted its formal Taiwan Stock Exchange IPO application on July 8, 2025.
