TGS expands offshore wind measurement campaign to five locations on US East Coast

TGS has announced an expansion to its offshore wind and metocean measurement campaign off the US East Coast. In addition to its floating LiDAR buoy in the New York Bight, TGS has announced four further deployments. One offshore Massachusetts, two covering the impending Central Atlantic lease round, and another buoy in the New York Bight area to further enhance its existing data collection and wind modelling of this area.

The TGS multi-client approach, where multiple customers can subscribe to the same floating LiDAR data, offers offshore wind stakeholders reduced development costs, timelines, and the ability to further minimise energy uncertainty. In the Central Atlantic, the TGS-deployed floating LiDAR buoys will provide data and insights on a subscription basis to those pursuing wind development opportunities allowing the de-risking of prospects before the lease bidding process.

This new floating LiDAR data will be the only full dataset covering the Central Atlantic lease areas, due to open for bidding in early 2024. Access to such data at this early stage is expected to enhance the decision-making ability of all stakeholders investing in the wind development future of this region.

In the New York Bight, TGS' first buoy in the region is performing well with high data recovery rates and measuring aspects of the wind resource not previously captured by prior modelling studies or measurement campaigns.

Adding a second TGS floating LiDAR buoy aims to further reduce wind and ocean modelling uncertainties and cycle times for those embarking on site assessment activities. This second floating LiDAR also aims to further validate TGS' numerical weather prediction (NWP) model data coverage. Similarly, those companies working on wind development offshore Massachusetts can acquire additional data to de-risk Final Investment Decisions (FIDs) or enhance Construction and Operations Plans (COPs).

In all five deployments, TGS is utilising a floating LiDAR system with the highest level of accuracy (stage 3 validation) from EOLOS. Throughout each buoy's deployment campaign, data will be acquired continuously with the data stream quality controlled and made available to customers daily via the Wind AXIOM platform, TGS' site evaluation, and wind data analytics tool. In addition to wind speed measurements, the data package includes metocean and environmental data such as wave heights, ocean current profiles, and acoustic monitoring of whales, dolphins, birds, and bats.

Using aggregated data inputs, including wind models and measurements, Wind AXIOM instantly accesses and processes vast amounts of site-specific data via the cloud. This functionality allows wind developers and stakeholders to constrain the most influential factors affecting the viability of offshore wind projects and answer questions related to energy output, annual revenue, supply fluctuations, and more. Wind model inputs are complemented by a range of cost-influencing factors, creating a tool that improves the quality and speed of decisions by offering a configurable experience for various participants in the offshore wind market.

Jan Schoolmeesters, EVP of Digital Energy Solutions at TGS, comments: "Having supported the energy industry for over 40 years with data driven insights, TGS understands the value of gaining early access to as much relevant data as possible in the project development cycle. We identified a need for wind measurements earlier in the development process, but the costs to deploy offshore measurements have been prohibitive and often don't make sense from a risk reward perspective. With the multi-client floating LIDAR program, TGS hopes to provide the best data earlier for greater risk reduction throughout the project."
