Early Phase Wind Development

Develop your offshore wind project sustainably and profitably

  • Port comparison analysis - evaluation of storage space and port restrictions
  • Installation methodology and strategy development
  • Project delay assessment: weather downtime, equipment breakdown, fabrication delay
  • CAPEX estimation - development of a cost estimation tool

How to ensure sustainable value creation for your offshore wind project?

We can help you develop a robust and cost-effective construction and maintenance strategy for your offshore wind project.

Identify risks early

We advise clients in the early development phase of offshore renewable projects. Our extensive knowledge in the industry enables our clients to develop their projects sustainably and profitably, identifying risks in an early stage. 

Solving Challenges

We look at the entire process and ensure to assess simultaneous operations that match onshore and offshore paces that can impact the project. 


The global energy transition needs offshore wind, but how can we de-risk projects?

At HES, we believe that developing realistic, robust, and ultimately cost-effective construction strategies at an early phase is essential for the offshore wind industry's success.

Improving projects

We help clients reduce project duration, costs, and weather downtime from the early-bid phase to commissioning.

Novel Methodologies

We develop novel installation and maintenance methodologies by performing feasibility studies and providing innovation support for engineering.

Providing Insights

We provide insights on construction duration and critical operations using our advanced logistical simulation software Metis.


HES Experience

Foundation Installation Calcareous Soil

We proved feasibility and developed an installation strategy for a bottom-fixed offshore wind farm in a region with calcareous soil types.
