How we do it

Combining pragmatism, commitment, lessons learnt and a positive attitude we help clients meet their goals. We know what it takes to realise offshore projects with hands on experience in realisation of more than 1GW of offshore wind farms.

Focusing on interface details but always keeping an eye to the overall picture is our strength. We bring to your project 9 years of offshore wind experience covering development, construction and operation of over €4 billion of offshore wind assets.

We draw on direct personal experience as technical advisor leading 3 projects to financial close, following 3 projects during construction and 2 projects during operations. Details of our involvement per project are provided below.
