Sensing of sediment plumes generated by construction activities in sensitive marine areas (SEDISENSE) (39525)

Project Details


SEDISENSE focuses on conceiving, designing and operating an autonomous system for mapping water turbidity in marine environment. The system is composed by a Remote Operated Vehicle equipped with fast response turbidity sensors and designed to perform autonomous mapping of large areas around a construction site in the Roskilde Fjord - which is situated in an EU classified Natura 2000 zone.

The project is in collaboration with M&E Engineering, and Arup a/s, who are currently partners for design and engineering for the construction in the Roskilde Fjord. Some of the construction activities have the potential to disturb to the local marine environment, in particular the sediment from the seabed, which can have potentially negative effects on the area. As such, M&E Engineering and Arup require a monitoring method for sediment disturbance beyond simple point-mapping, to reduce the environmental impact of future marine construction projects.
SEDISENSE can be divided into two main phases: 

(1) Laboratory testing: Laboratory testing includes calibration of the sensor and integration with the ROV, as well as developing a method for reconstruction of 3-dimensional sediment data which it will be providing. 

(2) Field trials: The field trials include initial testing of the ROV and sensor combination itself, field trials during construction activities, and data analysis. Laboratory testing will take place at DTU, with field trials taking place at Roskilde Fjord. Construction of the Roskilde Fjord bridge piles will occur within the first half of 2018. These activities will likely provide the most marine sediment disturbance, and therefore are the most appropriate activities to be monitored by the ROV sensor.
