Developer Enterprize Energy has commenced initial marine surveys off the coast of Binh Thuan province in Vietnam for its 3.4-GW Thang Long offshore wind project, the largest offshore windfarm to be granted a survey licence by the Vietnamese Government
Enterprize Energy has engaged Hai Duong Co Ltd (Haduco), a Vietnamese onshore/offshore and logistics provider that works across southeast Asia and the Thien Nam Positioning Company. They will supply vessels, personnel, and equipment to explore the bathymetry of the area and identify seabed features such as sand waves, reefs and shipwrecks.
From this initial survey work, Enterprize will focus its more indepth geophysical surveying on areas of the seabed with good construction potential and high wind energy yield.
Enterprize Energy development director David Wotherspoon said, “We have completed a full year of LIDAR wind data measurement which has confirmed the high potential of the wind resource in the area.
“Through this initial survey work, we will confirm which locations we will focus on for more intensive geophysical and geotechnical work in the near future. We can then optimise our development locations to ensure we are harnessing the best wind resource off the coast of Binh Thuan, working closely with local communities and existing sea area interests in the surrounding region throughout the development process.
“We are pleased that we have been able reach agreement with the fishing communities on a policy which was recently approved by the Binh Thuan People’s Committee. This example of closely working with the communities dependent on the sea area sets an example of good practice to be followed in the development of offshore wind in Vietnam.”
The first 600-MW phase of the project is due to come online by the end of 2025, with further phases developed on a rolling basis, subject to grid availability.
Vietnam is set to become a clean energy leader in the APAC region, targeting 21% installed renewable energy capacity by 2030. With an estimated 160 GW of wind energy potential in the region’s waters, the roll out of significant offshore wind projects will be key to meeting this target.
However, to ensure the local economic benefits of Vietnam’s transition from fossil fuels is fully realised, it will be crucial for developers to work directly with local supply chains to ensure projects are brought online in a manner which recognises, and works together with, existing crucial coastal activity, such as Vietnam’s tourism and fishing sectors.
