DFO contracts VARD for one Offshore Subsea Construction Vessel
VARD is pleased to announce that we have signed a contract with the Taiwanese based company Dong Fang Offshore for the design and construction of one Offshore Subsea Construction Vessel, with option(s). The vessel is of VARD 3 39 design. The value of the contract is EUR 113,5 mill.
03. April 2025

DFO was established in 2019 to deliver high quality marine construction, operations and maintenance services for the offshore wind, energy and telecoms industries. The company aspires to be the supplier of choice to deliver international standard cable installation and repair solutions in the wind and telecoms industries, operations and maintenance solutions for offshore wind farms, and the delivery of turnkey marine construction solutions in Asia Pacific. DFO has emerged as a contractor with the largest fit for purpose fleet of modern vessels in APAC, with strong local competence and industry-leading operational delivery and quality.
Designed for the future
VARD 3 39 design
Dong Fang Offshore has appointed VARD to design and construct an Offshore Subsea Construction Vessel of VARD 3 39 design. This is the third vessel VARD is building for DFO, with the first two being Commissioning Service Operations Vessels, contracted in May 2024.
The vessel contracted is a highly versatile platform designed and equipped for subsea operation duties, offshore wind operations & maintenance activities, as well as cable installation and repair scopes in the offshore wind and telecoms sectors. With its highly optimized hull form together with a powerful propulsion configuration, the vessel will have particularly good sea-keeping capabilities, including reduced motions and accelerations and excellent station keeping performance. The design has focused on the environmental footprint with an efficient machinery and propulsion set-up for high station keeping capabilities including battery hybrid propulsion, delivering improved workability and operational reliability.
Advanced subsea operations
The vessel is fitted with a 250 MT active heave compensated offshore crane which enables the vessel to perform advanced subsea operations, a 1,200 m2 work deck prepared for a cable repair or cable lay spread, and ROV hangars prepared for built-in ROVs on both sides.
The large design flexibility allows the vessel to accommodate future operational demands. The vessel is prepared for the installation of a motion compensated gangway, an under-deck carousel, the installation of a large trencher and is in addition prepared for helideck installation.
The vessel has 90 cabins to accommodate 130 people on board. Operational centers such as offices, briefing rooms, conference room/cinema and dayrooms have been designed to meet a high standard in the market, and furnishings will be completed to a premium standard by Vard interiors.
Returns to VARD
- We are pleased to return to VARD with a new order for a Offshore Subsea Construction Vessel to support our growing international client base. The order complements the two SOV’s we have ordered against long-term contracts and opens the door for DFO to expand its service offering in the offshore wind, energy and telecoms markets. Furthermore, this new order together with the option(s) attached to this agreement ensures that DFO continues to build fleet scale and latitude to continue to deliver a one-stop solution to our customers. The choice of Norway as a build country for our first ever newbuild OSCV also ensures that we continue to deliver on our promise of on-time, high quality, reliable services to our valued customers, as well as delivering a safe and comfortable work environment for our crew and clients staying on board, says Polin Chen, CEO in DFO.
Integrated value chain
Deliveries from the VARD integrated value chain
Through our integrated value chain, we are delivering the design, building the hull, outfitting, integrating, and commissioning the ship for the customer.
Vard Electro is delivering a fully integrated power and automation system, emphasizing total system efficiency to ensure optimal environmental considerations. This system is monitored by the SeaQ Green Pilot, which collects all digital data from the vessel and makes it accessible through Vard Electro’s cloud service to office desktops. The vessel is also equipped with the market-leading SeaQ Bridge.
This installation provides the vessel operator with comprehensive oversight and control of all onboard systems from a single location, enhancing both operational safety and efficiency. The SeaQ Bridge is a pivotal enabler for more digital ship operations, incorporating applications that minimize the need for manual panels.
Vard Interiors will provide HVAC-R, piping systems and modern interior solutions designed to create environments that are both functional and conducive to individual well-being and productivity aboard the vessel.
Proud and honored
- We are proud and honored that DFO has chosen to return as a customer to VARD. This contract is yet another token of VARDs ability and proven record to deliver vessels on time and budget. Together with our owner Fincantieri we are collaborating with customers worldwide to tailor-make vessels based on the customer's needs and requirements, and this vessel has been developed in a fruitful process together with the customer. We look forward to continuing our good collaboration with DFO in the years to come, says Cathrine Kristiseter Marti, CEO in VARD.
