When you have the right data, you can make the right decisions

Profitable offshore developments begin by asking the right questions about your site. Let’s gather the insight you need to make your commercial decisions with confidence.

The development potential of a new site is always exciting. But the offshore sector is growing fast. New sites are often in deeper water, posing greater geological and operational challenges. Achieving profitable outcomes begins with asking the right questions about your site, right from the outset.

We have the expertise not only to assess site feasibility, but to supervise and manage all stages of a site survey and ground investigation – making sure you gather the data you need, without paying to capture data that you don’t.

Perhaps you want to understand if a lease area is worth bidding on. Or maybe you want to identify the most cost-efficient locations to place foundations. We give you total clarity on the risks and the opportunities. So you can make confident commercial decisions.

How we help

Our services include:

  • Desktop studies and open-source data collation
  • Preliminary conceptual ground models
  • Geophysical survey/SI specification and scoping
  • Contractor tender review and selection support
  • Final engineering and construction ground models

Accurate insight

Get the project spec and scope of investigations right first time. Quickly understand the risks and viability of development.

Cost management

Gathering the right data doesn’t mean conducting every survey imaginable, across every square inch of your site. We make sure you capture the data that matters. No more, no less.

Site Investigation

We have in-house geophysical, geotechnical and geomorphological expertise. That means you can come to us to reveal the true characteristics of your site – mapping the seabed, identifying what it’s comprised of and discovering the risks.

Outcome orientated

Every project is different. Our investigations are always conducted to align with your developmental ambitions.

Commercially focused

We keep a keen eye on the bigger commercial picture – whether that’s identifying red flags as early as possible or making sure there are no surprises when it comes to construction.

Ground Modelling

It’s impossible to overstate the importance of an accurate ground model. This visualisation of the data gathered on your site informs everything from the design and installation of your project right through to its eventual decommissioning. When data accuracy is essential, it pays to work with an expert.

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

“Jess has and is doing an excellent job on the project in what has been a challenging situation. Jess is positive and pleasant to work with and builds rapport well. She clearly has excellent offshore geophysical experience.”

Lee Goulding, Director of Engineering, Thistle Wind Partners

The more you work with us,
the more you derisk your project.

The lifecycle of any offshore development is intricately connected. Each phase – and its success – is contingent on the phases that came before. It’s why working with an independent expert can generate huge savings. When each part of the process is conducted meticulously, without losing sight of the bigger picture, the impact on costs can be transformative. Let us help.
