U.K. Medmerry Managed Realignment Scheme Wins WODCON Coastal Resilence Environmental Award

U.K. Medmerry Managed Realignment Scheme Wins WODCON Coastal Resilence Environmental Award

Medmerry Managed Realignment is the largest open-coast scheme in Europe, the first in the United Kingdom, and one of the most sustainable projects the United Kingdom Environment Agency has ever delivered. Located on the south coast of England in Sussex, it was known to be one the most flood-prone and vulnerable parts of the southern coastline. The threat of flooding has long caused concern because of the risk to nearby towns as well as to the natural wetland and intertidal habitat.

Boeing’s Restoration at the Duwamish Waterway Receives Environmental Dredging Award

Boeing’s Restoration at the Duwamish Waterway Receives Environmental Dredging Award

Boeing recently completed a multi-faceted environmental restoration of a one-mile portion of the Duwamish Waterway, removing contaminated sediments and creating acres of new aquatic habitat critical for endangered salmon migration as well as new vegetated marsh and riparian areas. The birthplace of the Boeing Company and the B-17 Flying Fortress bomber that was critical to national defense during World War II has been transformed by innovative remediation dredging methods (RDMs) developed for the project. These RDMs demonstrate that contaminated sediment can be removed efficiently without adverse release of chemicals to the water. The Duwamish Waterway area has gone from a camouflaged bomber plant that helped win World War II to an invaluable natural habitat. The project addressed more than a century of impacts from industrialization along the waterway and throughout the entire watershed.

One was the appointment by Nobelwind of JDN as Engineering-Procurement-Construction-Installation (EPCI) contractor to install all foundations and the 50 3.3 megawatt (MW) MHI Vestas wind turbines offshore at its fourth offshore wind farm in Belgian territorial waters. These turbines will have an installed capacity of 165 megawatt and will supply green power to 186,000 Belgian households yearly. The first foundation components arrived in the harbor of Oostende on March 23. The first installation offshore started in May, when the installation vessel, Vole au vent, picked up the foundation components and brought them to the site at sea. The installation of all foundations is expected to last until the beginning of September, depending on weather conditions.
