Offshore Renewables & UXO

Innovative Survey Tools for the Green Energy Transition

At every stage of an offshore wind farm’s lifecycle, side scan sonar plays a critical role. From initial site assessment and seabed characterization to ongoing foundation inspections, high-quality seafloor imagery ensures safe, reliable, and well-maintained infrastructure.

Klein’s global reputation for high-resolution, photographic-quality sonar imagery makes us a trusted partner for renewables operations worldwide. Our full range of side scan sonar solutions is compliant with all major survey guidelines, including:

• European Offshore Renewable Energy (SSS-A to G)

• US Offshore Renewable Energy (Reconnaissance, COP Boulder, UXO, Seabed Mobility)

• BOEM Geophysical Guidelines

• SUT-OSIG standards

With Klein, operators can achieve accurate, reliable, and guideline-compliant surveys, supporting every phase of offshore wind development and ensuring long-term operational confidence.

Geophysical and UXO Surveys

As offshore survey guidelines become increasingly stringent, Klein’s side scan sonar technology helps future-proof operations, reduce risk, and deliver high-quality seafloor data.

The Klein 5900 sonar is capable of detecting objects as small as a golf ball at survey speeds up to 12 knots, making it ideal for geophysical site assessments and Unexploded Ordnance (UXO) surveys.

Integration of AI-based Automatic Target Recognition (ATR) further enhances efficiency, reducing the time needed to detect, locate, and classify objects of interest, and enabling near-real-time decision-making in the field

Localized Seabed Assessment

Regulatory guidelines often require recent seabed surveys—typically conducted within the past six months—before offshore operations can begin. Klein’s rapidly deployable, easy-to-use side scan sonar systems are ideal for updating survey data efficiently and cost-effectively.

With two dedicated UUV payloads, operators can utilize micro or standard AUVs to refresh seabed surveys, minimizing mobilization time and operational costs while maintaining high-resolution, reliable data.

Foundation Inspection

The seabed around offshore wind turbines is dynamic, requiring regular foundation and scour inspections to ensure structural integrity. Whether deployed from a traditional survey vessel, unmanned surface vehicle (USV), or autonomous underwater vehicle (AUV), Klein’s side scan sonar systems deliver high-resolution, photographic-quality imagery that enables operators to assess seabed conditions and monitor scour around offshore structures effectively.
