Meet the Team: Jeffrey Davis
At OWC, our teams are constantly expanding into more locations, in expertise, and in sectors of influence. Our people are at the heart of what we do, and we invite you to get to know our team members so you can meet the energy behind change.
As offshore wind projects become larger, more complex and increasingly capital‑intensive, understanding cost drivers, and how to manage them, has never been more critical.
Based in Hamburg, Jeffrey is a Principal Consultant in OWC’s Cost Engineering team, supporting offshore and onshore wind developers and investors with robust, market‑informed cost modelling and commercial insight across the full project lifecycle.
With current market conditions placing renewed scrutiny on project economics, Jeffrey and the wider team help clients navigate uncertainty, strengthen bankability and unlock value through deeper understanding of CAPEX, OPEX and LCOE drivers.

Give us a glimpse into your day-to-day life at OWC? What keeps you on your toes?
Offshore wind is a constantly evolving industry, with new markets, regions, and technologies to characterize and evaluate on a global scale. Recent market conditions have put a very fine lens on project costs and financing, and keeping updated on the latest changes has become a key value-add for our clients.
From understanding shifting supply chains to assessing how new technologies impact cost and risk profiles, cost engineering today is as much about commercial, technical and operational insight as it is about numbers.
What drew you to the industry and what keeps you passionate about it?
I started my career in onshore wind and I’ve been happy to transition to offshore for more opportunities to explore renewables on a global scale. Larger projects with a global supply chain and more complex contracting structure have been a fun challenge so far.
Can you tell us about something exciting you are working on right now?
One of my current projects is focusing on the commercial evaluation of deepwater foundation solutions for offshore wind turbines. These new technologies are looking to use existing manufacturing techniques and installation strategies to bring fixed-bottom solutions to water depths up to and exceeding 100m.
Understanding whether, and where, these solutions make economic sense is key to enabling future project viability.
With some headwinds in German and wider European offshore wind – how can cost engineering help tackle uncertainty to support renewed investor appetite?
With markets shifting and the cost of capital increasing, we’re seeing renewed interest from developers in revisiting business plans post‑award. Cost reduction and value optimisation have become major priorities.
By exploring alternative supply chain options and applying deep‑dive value engineering, we help clients reduce project costs, improve bankability and ultimately support renewed investor appetite.
Beyond the work, what makes you tick outside of the office?
I’m lucky to have family and friends scattered across many corners of the globe and spending time with them is a big focus for me.
