EUROPEAN CONTRACTORS PLAY MAJOR ROLE IN OFFSHORE WIND FARMS

Both 2015 and the first quarter of 2016 saw a series of new contracts with major dredging companies for the installation of European off-shore wind farms. These contracts constitute a significant part of the turnover for the four major European dredging companies. (See stories below). In general, the dredging companies are responsible for operations such as preparing the seabed to receive the windmill foundations, placing them and backfilling with rock after the platforms have been placed to stabilize and protect them from currents and severe weather. Next to these activities, however, the dredging companies are more and more often joint venture partners and main contractors, providing both financing and managerial capability, as well as extensive maritime expertise.

Corps Performs Lakebed Imaging Study for Erosion Analysis

Last year, the U.S. Army Corps of Engineers Detroit District began a lakebed imaging study to determine changes near the New Buffalo, Michi-gan, area. The Detroit District Hydrology and Hydraulics Office is analyzing the data to under-stand how the sand is moving and why, and what might be done to alleviate problems with erosion. In September 2015, 11 scientists and engineers spent two weeks collecting data to quantify the changes in the amount of sand in the coastal zone.
