Marine Surveys Start on 3.4 GW Wind Farm Offshore Vietnam

Enterprize Energy has kicked off initial marine surveys off the coast of Binh Thuan province in Vietnam for its 3.4 GW Thang Long offshore wind project.


This is the largest offshore wind farm to be granted a survey licence by the Vietnamese government, the developer said.

Enterprize Energy has engaged local marine services providers Hai Duong Co Ltd (Haduco) and the Thien Nam Positioning Company for the work across an area of 2,000 km2 allocated for the project.

They will supply vessels, personnel, and equipment to explore the bathymetry of the area and identify seabed features such as sandwaves, reefs, and shipwrecks.

From this initial survey work, Enterprize will focus its more in-depth geophysical surveying on areas of the seabed with good construction potential and high wind energy yield.

”We have completed a full year of LIDAR wind data measurement which has confirmed the high potential of the wind resource in this area. Through these initial survey works, 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 that 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,” David Wotherspoon, Development Director for Enterprize Energy, said.

The USD 11.9 billion (approximately EUR 10.1 billion) Thang Long project will be built in several phases.

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, the developer said.

The project will feature Vestas (MHI Vestas) wind turbines.
