Enterprize Energy launches Vietnamese floating LIDAR survey

Enterprize Energy has commissioned Fugro and its Vietnamese partner, PTSC, to install floating LiDAR survey technology at the 3.4 GW
Thang Long offshore wind farm – the first time such technology has been used in Vietnam.
This announcement for the installation of floating LiDAR marks the next step in the surveying process for Thang Long, the only large-scale offshore wind farm to be granted a survey licence by the Vietnamese government. To date, a full year of wind data measurements have been collected via fixed LiDAR to assess resources over the allocated area, with reconnaissance surveys to support the project team’s understanding of geological and seabed features occuring earlier this year. Based on initial results, Enterprize Energy has confirmed there will be no reduction in prospective area due to unsuitable seabed features such as basalt intrusions.

Enterprize Energy has engaged Fugro and its local partner, PTSE, to deploy Fugro’s ‘SEAWATCH Wind LiDAR Buoy’ to collect detailed wind resource, meteorological, and oceanographic data across the 2000 km2 project site over the next 12 months. The technology - comprising the SEAWATCH Wavescan Buoy as a platform into which the ZX 300M LiDAR is integrated - will track air pressure, humidity, air and water temperature, wave height and current, with support from a guard vessel which will also track fishery activity and supplementary ocean data from its own onboard sensors.

Ian Hatton, Chairman of Enterprize Energy, said: “Contracting Fugro and their local partner PTSE to install the first floating LiDAR technology in Vietnam at the Thang Long project site was a natural decision for us. The data the team will collect is central to informing the next stages in Thang Long’s development process, including long-term financial modelling and power purchase agreements.

“The results from our initial marine survey demonstrate that, as we had predicted during our proposal for a survey license, a majority of the seabed throughout the Thang Long Zone is suitable for placing turbines. Now, we can quantify how much energy can be generated throughout the project based on using all of the seabed we initially planned to build on.

“We are delighted to have taken another step towards harnessing the incredible wind resource off the coast of Binh Thuan, bringing a further 3.4 GW of renewables into Vietnam’s energy mix and opening up the opportunity for even more green energy capacity as we explore the potential for energy storage. We have lain the foundation upon which the full potential of the Thang Long zone can be released for the benefit of the Vietnamese people, in line with national planning and policies.”

Mr. Truong Tuan Nghia, Director of PTSC G&S, also stated: “Today's signing ceremony shows our respect for the cooperation with Enterprize Energy, and this is an important milestone for our next steps in the future. PTSC G&S believes that, with the experience of leading experts, technical facilities and high-class equipment, can provide the best service in developing the Thang Long Wind project.

“With the support from Enterprize Energy, together with our long-standing partner – Fugro Singapore Marine, and commitment from all levels of our organization, PTSC G&S is fully confident that the project will be completed within the agreed time schedule, to the highest quality and safety standards”.

Thang Long offshore wind power project is located 20 km to 60 km from the coast of Binh Thuan, featuring water depths of around 30 to 55 metres. The site is expected to host 3,400 MW, divided into several investment phases, each with a capacity of approximately 600 MW. Investment capital for the entire project is estimated at USD 11.9 billion, not including the investment for connecting to the national electricity system. 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.
