Aarsleff Bilfinger Berger JV London Array

The Aarsleff Bilfinger Berger JV London Array refers to a joint venture between Per Aarsleff A/S and Bilfinger Berger, specifically associated with the London Array project. The London Array is one of the world's largest offshore wind farms, situated in the Thames Estuary in the United Kingdom. Here’s a brief outline of the entities involved and their contributions:

Per Aarsleff A/S

• Based: Denmark


• Specialization: Civil engineering, infrastructure, and foundation engineering.


• Role in London Array: Provided expertise in heavy foundation works, which was critical for the installation of offshore wind turbine foundations.

Bilfinger Berger

• Based: Germany (now part of the Bilfinger SE group, after several restructurings).


• Specialization: Engineering and construction, with capabilities in both civil and industrial sectors.


• Role in London Array: Partnered in providing comprehensive engineering solutions, infrastructure support, and project management.

London Array Project

• Location: Thames Estuary, UK


• Capacity: Initially up to 630 MW (megawatts), making it one of the largest operational offshore wind farms globally.


• Construction Timeline: Major construction began in 2011 and the first power was produced in October 2012. It was fully operational by mid-2013.


• Significance: The project plays a significant role in contributing to the UK's renewable energy supply, aimed at reducing carbon emissions and providing sustainable energy solutions.

Joint Venture Role

The joint venture between Aarsleff and Bilfinger Berger was instrumental in the construction phase, focusing primarily on the complex, large-scale installation of offshore foundations which require significant expertise and resources. Their combined knowledge and experience ensured that the project met its structural and environmental standards.

Key Activities

• Foundation Installation: The JV was responsible for deploying innovative techniques and equipment to install the turbine foundations in the challenging marine environment.


• Infrastructure Support: Besides foundations, they also provided ancillary infrastructure such as subsea cabling and substation support structures.

Environmental Impact

The London Array project, including the work performed by the Aarsleff Bilfinger Berger JV, adhered to stringent environmental regulations to minimize impact on the marine ecosystem and surrounding environment.

Outcomes and Legacy

The successful completion of the London Array has demonstrated the viability and importance of large-scale offshore wind projects. The collaboration between Aarsleff and Bilfinger Berger set a benchmark for future renewable energy projects globally, highlighting the importance of joint ventures in pooling expertise and resources to tackle ambitious engineering challenges.
