Site investigation that gets to the bottom of your project

When you know what’s happening below the waterline, you can make confident design, development and commercial decisions. But only if your data has been captured accurately.

For confidence in your decisions, you need confidence in your data

Drawing from decades of offshore survey vessel experience, our team guides clients through the complex, costly process of seabed investigations with precision and care. We collaborate closely with you to design, procure, manage, and interpret data acquisition, while our fully qualified representatives act as your advocates aboard vessels, ensuring high-quality data collection backed by round-the-clock onshore support.

From initial planning through completion, we maintain rigorous quality standards as our experienced geoengineers verify all data both offshore and onshore. Ternan continues supporting your project through reporting and laboratory phases, providing expert guidance on testing requirements and thorough quality checks of contractor deliverables. Working as your integrated partner, we ensure every piece of information collected serves your project needs, optimising foundation design and mitigating installation risks throughout the entire process.

Client feedback

What do our clients think?

“Throughout the project Ternan has been easy to work with, responsive and helpful, and were a key deliver partner for the project. We will certainly be approaching Ternan again for future projects.”

Neil Crawford, Subsea Cables Package Manager, Ocean Winds

“Kent have worked with Ternan Energy on several projects now, where Ewan Fielding was the Geotechnical project engineer focal point. Ewan has consistently shown his ability to manage the project scope of work Ternan were required to deliver, including great responsiveness every time it was required and providing a clear and proactive communication to manage expectations and deliveries.”

Kent Group PLC

“…all four of the client representatives were excellent and I wouldn’t hesitate to recommend any of them to other projects or work with them again. All four were on board through some quite difficult situations for various different reasons during this campaign and all were handled very professionally with excellent communication onshore.”

Amelia Chilcott
Site Investigation Package Manager 
RWE Renewables UK

FAQs

How long until site investigation data is available?

Typically it can take many months to turn site investigation data into a ground model. However we have developed software that provides a preliminary visualisation of site data – such as bathymetry and seabed composition – in as little as 24 hours. It enables you to react quickly to initial survey findings, transforming the speed at which key decisions can be made among the stakeholders in your project. Ask us for more information.

Do you have the right expertise?

Ternan Energy is a highly specialised team of geophysical, geotechnical and ocean engineering experts. We have provided insight on site investigations all over the world. And we can do the same for you.

How quickly can you react to my project?

Because we are an independent specialist, we can stay nimble and responsive to incoming projects. It’s all about capturing the data you need, while remaining sensitive to your deadlines and timeframes. Try us.
