Abstract [en]

Sea transport is increasing due to its environmental and economic benefits. The related expansion of ports and the development towards longer, wider and more deep-draught ships cause a huge need for dredging of sediments in fairways and ports. A large volume of these sediments are contaminated with heavy metals and organic contaminants. Millions of m3 of these sediments have to be dredged and handled in the coming years according to studies performed by the SMOCS/PortInfra network. The SMOCS project (Sustainable Management of Contaminated Sediments) within the Baltic Sea Region Programme 2007-2013 has developed a guideline on management of contaminated sediments based on a sustainability approach. This paper deals with important considerations and key experiences in the different phases in a project from characterisation of sediments to be dredged, basic risk assessment, feasibility study and selection of handling options, planning and permitting, execution incl. detailed design considerations and field test and serviceability stage incl. monitoring. The stabilization/solidification technology has been applied implying the beneficial use of such treated dredged contaminated sediments in port constructions reducing the use of natural resources.

Abstract [fr]

Le transport maritime est en augmentation en raison de ses avantages environnementaux et économiques. L’expansion des ports que cela implique et l’évolution vers des navires plus longs, plus larges et à plus fort tirant d’eau provoquent un énorme besoin de dragage des sédiments dans les chenaux et les ports. Une proportion importante de ces sédiments est contaminée par des métaux lourds et des polluants organiques. Des millions de mètre cubes de ces sédiments devront être dragués et pris en charges dans les années à venir, selon les études réalisées par le réseau SMOCS/PortInfra. Le projet SMOCS (Gestion durable des sédiments contaminés), faisant parti du programme régional de la mer Baltique 2007-2013, a élaboré des recommandations sur la gestion des sédiments contaminés basées sur une approche de développement durable. Cet article traite des considérations importantes et des expériences clés des phases successives d’un projet, de la caractérisation des sédiments à draguer, en passant par l’évaluation des risques, l’étude de faisabilité et la sélection des options de gestion, la planification et les demandes d’autorisations, jusqu’à l’exécution incluant les détails de conception, les essais pilotes et les mesures d’entretien incluant la surveillance. La technologie de stabilisation / solidification a été appliquée ce qui a conduit à l’utilisation efficace de sédiments contaminés traités dans les constructions portuaires en réduisant l’utilisation de ressources naturelles finies.
