Marine-Based Solids Management

"Marine-Based Solids Management Eliminates Need for Open Barge Transport, and Land-Based Dewatering and Transportation Facilities for Contaminated Sediments"

During operations to remove contaminated sediments from a dredge work area, the collected sediments must be transported and transferred to land-based facilities that are designed to remove excess water and prepare the processed sediments for transport to a final disposal site.

The construction and operation of such land-based facilities introduces permitting issues and local community impacts that in many cases prevent cleanup projects from proceeding in a timely fashion.

Seaway's "Marine-Based Solids Management System" is a solids handling technology that provides for safe, clean, and containerized management of contaminated sediments on marine platforms. It eliminates the need for the transport of contaminated sediments in open barges or the pumping of muds to shoreside storage lagoons. It provides the means for collecting, processing, containerizing and transporting contaminated sediments on the water without the need for land-based facilities.

Seaway utilizes two types of vessels in this Marine-Based Solids Management Operation: 1) a solids processing vessel, which removes large debris and stabilizes the sediments (muds) with cementitious reagents and 2) a container transport vessel, which carries containers into which the stabilized sediments can be deposited, sealed and transported to an existing port facility, where the containers can be off-loaded for transport by rail to a final disposal site.
