B1. Construction of the dredging equipment and dewatering and treatment site (completed)
The objective of this activity was to construct the dredging equipment, but also to build the treatment system to take care of the dewatering and the rejected water.
1. Design and construction of a new dredging unit and surface raft
The aim of this activity was to construct and assemble the dredging units that are used on the test site in the bay of Malmfjärden.
Because of problems with the original prototypes, the construction phase of the dredging units took longer than expected. In spring 2020, a new dredging unit, Mudster, was finally ready.
The dredging system Mudster consists of three main components:
- an underwater dredging unit
- a control raft at the surface and
- a wire system that moves the raft.
2. Construction of the dewatering and reject water system
The treatment site is a small area close to the test location, where the dredged masses are collected, dewatered and the reject water is treated and then released. In order to steer and control the uptake and treatment of the sediment, a special program was developed for LIFE SURE.Read more about the unique design solutions of the dredging units and dewatering system in the design document
LIFE SURE has produced several films, presenting the concepts and solutions developed in LIFE SURE.

A1. Planning and preparation
Project management and project partners need to plan and prepare for the stages in the project.
B2. Installation and small scale test drive
To know how to fully use the equipement in full scale, we will first test the system in small scale.
B3. Large scale demonstration
Based on the knowledge of the small scale test, we will perform full scale dredging and treatment.
C1. Monitoring and evaluation
The focus for monitoring and evaluation is mainly to follow up the effects of the dredging activities.
