Sustainable Management of Contaminated Sediments (SMOCS)
European workshop “Sustainability assessment and Management of Contaminated Sediments in Ports”, Hamburg, 12-13 October 2011
SMOCS hosted a workshop in Hamburg, on 12-13 october 2011. The workshop covered incorporation of sustainability as well as tools to be merged into the guideline that will be developed in the project. Key-note speakers are were Geert Norgaard of the Baltic Ports Organisation and Axel Netzband of the Hamburg Port Authority and Erik Westin, Swedish EPA. Documentation from the workshop can be obtained from SMOCS Communications, please contact bo.svedberg@ltu.se.
Site visit at port of Kokkola, Finland, in September 2011
The port of Kokkola hosted a succesfull site-visit and workshop in mid September. There was several participants from all around the Baltic networking on the issue of environmental dredging and stabilzation & solidification of contaminated sediments. Further info concering the event will be presented in the next Newsletter.
Mapping of sediments in port of Klaipeda, Lithuania, in April 2011
Representatives from Maritime Institute in Gdansk, Ramboll Finland, Lithuanian Maritime Safety Administration and Coastal Research and Planning Institute in Klaipeda took part in the workshop on demonstration of the sediments mapping performed in Klaipeda Sea Port.
Van veen grab sampling, parametric subbottom profiling and multibeam echosounding where introduced during the three hours field trip in the Klaipeda Strait. The workshop included also a discussion on progress and plans for the development of a joint sampling/mapping strategy, which will form an important basis to be used by ports for future mapping of sediments.
Demonstration of the stabilisation & solidification technology at a field test in Port of Gävle, Sweden, in October 2010
The Port of Gävle is expanding its business as a multi module logistic hub for trade in mid Sweden. In order to meet the future demand, the port is developing new port areas and dredging the fairways to enable deep draught ships. The dredging of the fairways is made in close cooperation with the National Maritime Administration. In order to manage about 1 million m3 of contaminated sediments the Portof Gävle is using the stabilisation and solidification technology. Thus enabling beneficial use of the contaminated sediments as base for new land, reducing use of natural resources and saving money compared to other handling alternatives.
One key issue of the demonstration at Port of Gävle is to modify and improve the process stabilization technology prior to the large scale works that will be performed in 2011 and 2012.
In Port of Gävle the binder components cement, granulated blast furnace slag, and fly ash, is mixed into the dredged material. Prior to the demonstration extensive laboratory investigations have been performed including environmental (leaching) and geotechnical (strength) properties. As a part of WP6 in the project SMOCS these tests will be correlated to the properties achieved in full scale in order to propose more detailed design and construction criteria.
