A contract has been signed for the supply of a new alarm and monitoring system (AMS) onboard a trailing suction hopper dredger (TSHD).

Alewijnse Marine won the AMS contract for DEME's 17,000 cubic-metre TSHD Nile River. The contract includes the engineering, installation and commissioning of the new AMS hardware and software. Together these will form the system that will be collecting, monitoring and displaying sensor data, alarms and other relevant information. In addition, Alewijnse will be checking and testing all existing sensors and alarms on board.

Johan van Rikxoort, product manager dredging & offshore at Alewijnse, commented: “The current Ricom 3000 system dates back to when the Nile River was built in 1999. The new system will be much more user-friendly and efficient to operate and enables more graphical options for the display and diagnostic functions.”

Well prepared

Alewijnse will deliver a pre-configured and tested system and the Alewijnse installation team on-site will also replace the old input / output boards and workstations, together with the local operator panels located throughout the vessel. The system will be operational before the end of the year after which the Nile River will be fully optimised to carry out her worldwide dredging tasks for DEME and its clients.

The order follows the earlier successful PLC (programmable logic controller) refit in 2017 and SCADA control system refit in 2018 onboard the Nile River.

Alewijnse has delivered the PLC refits for several DEME dredging and offshore vessels and was responsible for a part of the electrical outfitting of cable-layer Living Stone.
