Significant order
The order is of great importance to Aarsleff. ”We focus very much on establishment of offshore wind farms in Northern Europe, and we are well-prepared for the development of solutions that are optimised in terms of technology, economy and time”, says Lars Carlsen, deputy general manager.

The Aarsleff Bilfinger Berger JV, referred to as ABJV, is one of the world’s leading companies within installation of offshore wind farms and is currently executing the world’s largest offshore wind farm London Array at the Thames estuary in the North Sea. The London Array Offshore Wind Farm consists of 177 monopile foundations, and ABJV’s contract concerns production and installation of foundations as well as installation of wind turbines.

The order does not affect Aarsleff’s expectations for the financial year 2010/2011.
