Hydrographic Survey

Whether you are planning a new offshore wind farm development, or monitoring existing infrastructure, understanding bathymetry is a vital task. Failure to track seabed morphology can lead to over-budgeting of infrastructure requirements, or increased costs from remediating defects due to unsuitable foundations or poorly designed cable routes.

We perform seabed mapping from nearshore and hazardous shallow water to deep water environments, using a range of hydrographic surveying methodologies, including multibeam bathymetry, side scan sonar, sub-bottom profiler, 2D-UHR and magnetometry surveys.

Operated by our highly experienced team of hydrographic surveyors, our innovative solutions are tailored to meet your quality, sustainability, schedule, and cost requirements. Supporting site consenting, pre-construction and cable route surveys, our survey solutions accelerate the acquisition of industry-leading hydrographic data.

Geophysical Survey

Conducting geophysical surveys at the design and planning stages of your project helps to identify and mitigate hidden hazards which could be faced by offshore project teams and contractors.

Supporting your offshore wind development activities, we deliver geophysical survey solutions at all water depths, minimising project risk, improving safety and facilitating the route and project design for offshore developers.

Seismic Survey

We utilise 2D Ultra High Resolution (2D-UHR) seismic survey technologies, providing a detailed picture of sub-bottom structures and shallow sub-surface seismic stratigraphy, which can play an important part in offshore wind farm foundation studies.

Our expertise in seismic data interpretation provides offshore site developers with critical insights required for positioning new turbines securely on the variable sediments and mobile sea floor, helping to reduce costs and extend the lifespan of offshore wind infrastructure.

Shallow Geotechnical Survey

To provide further understanding of the composition of sediments at and below the seabed, geotechnical sampling is undertaken. Cone Penetration Testing (CPT) provides in situ measurements of a soil’s properties, while a vibrocorer is used to provide physical sediment samples that can be analysed in further detail.

Geotechnical analysis supports ground-truthing of geophysical data, providing greater certainty of physical seabed properties across the survey area. Running geotechnical operations alongside hydrographic survey, geophysical survey and other work packages improves value through fewer mobilisations and acquisition synergies.

Marine Environmental Survey

In supporting the planning, consenting and development and environmental protection across new offshore developments, we understand the importance of recording an monitoring the complete environment. That is why our integrated survey capabilities are designed to combine the acquisition of physical, chemical, and biological data sets simultaneously.

Working with trusted environmental science partners, we offer a broad range of specialisms, delivering industry leading data insights in a concise report. Our extensive environmental survey solutions range from benthic studies for species identification and abundance, water chemistry analysis exploring dissolved O2, pH and temperature in addition to meteorological observations at the project location.

Marine Archaeology

Offshore wind farm developments can occupy a significant area in the oceans, and turbine foundations pose the risk of impacting archaeology. We recognise the importance of subsea archaeology; there are far fewer sites in comparison to land, and these may contain artefacts of historical significance that are not found elsewhere. We understand how critical it is to ensure that archaeological methods are efficient and executed with precision and care, to protect these valuable assets for future generations.

UXO Identification & Clearance

Unexploded ordnance (UXO) continue to pose a real risk to site developers, contractors and asset owners, even after decades of inactivity.

We are experienced in identifying, investigating and mitigating hazards with precision and expediency. Fusing our expertise together with sub-bottom imaging technology and our SubSLAM X2 intelligent data collection system and sub-bottom imaging technology, we can accurately detect ferrous and non-ferrous items of UXO both above and below the seabed, generating full 3D models of UXO and other artifacts of historical importance in-situ and in real-time.

In doing so, we substantially reduce the amount of vessel time required to investigate false positives, delivering considerable cost savings and a significant reduction inemissions. Additionally, we provide expertise and assets to precisely identify and remove boulders and other obstructions from the seabed safely and efficiently.

Cable Route Planning

Eliminating uncertainty about offshore subsea site conditions, we help our clients mitigate risk and ensure the long-term performance of their assets. Our technical studies and surveys deliver insights that provide a thorough understanding of offshore wind development areas and cable routes, guiding layout and design.

Through state-of-the-art data collection and in-house analysis, we enable informed decisions and the de-risking of complex projects. Furthermore, our comprehensive range of solutions also support the conservation of the marine environment and the sustainable development of large marine assets.
