Alewijnse secures another order for the AIViVi system

Alewijnse and DEME Group have signed their seventh contract in just two years for the supply and installation of an Alewijnse virtualisation and visualisation (AlViVi) platform, on board another DEME trailing suction hopper dredger.


According to the announcment, this latest contract reaffirms the successful cooperation between DEME and Alewijnse in the field of automation and digitalisation. Together, the two companies have to date successfully completed over twenty such projects over the past five years.

AlViVi is an innovative control system jointly developed by Alewijnse and DEME to enable the faster and more efficient development and maintenance of IT systems on board vessels and offshore installations.

The solution is based on a central, redundant server system that virtualisates all dredging process-related data. The result is that the data generated by the systems centralised within AIViVi can be visualised and manipulated from any connected screen onboard the ship.

This means that the innovative platform replaces around 75% of the computers, keyboards, video and mouse (KVM) hardware and significantly reduces the cabling requirements. The AIViVi digitalisation solution is already up and running on six trailing suction hopper dredgers in the fleet of the DEME Group.

Alewijnse and DEME have been working together intensively since 2015 on automation and electrical installation solutions for DEME’s dredging fleet. Alewijnse closed the contract for this latest order due to its proven high quality of service, expertise and performance combined with previous successful implementation of the technology on other DEME dredgers and offshore vessels.

“The awarding of this latest order is a confirmation of our many years of successful cooperation. DEME has once again demonstrated the confidence it has in us to deliver a digitalisation solution in the form of an innovative and successful platform for hosting their dredging software together with that relating to equipment supplied by third parties,” said Johan van Rikxoort, Product Manager at Alewijnse.

“The platform is fast, user-friendly and extremely reliable, resulting in maximum uptime and optimal operational security. By bringing together multiple systems in one environment, their maintenance and management becomes much easier and more efficient. Updates are better and faster to test or roll back. In addition, the life-time of the software is extended by the independence of the platform and the system is also extremely secure from intruders,” commented Product Manager Johan van Rikxoort.

Alewijnse has played a significant role in the development and implementation of automation and electrical installations on board the dredging and offshore vessels operated by DEME.

The Dutch systems integrator is a proven partner in the field of dredge automation systems, dredging process solutions and dredging control systems.

Previously projects include the PLC refit and development of dredge application solutions on board the TSHDs Nile River, Lange Wapper and Uilenspiegel; as well as a new alarm and monitoring system on board the Nile River and an upgrade of the ADLS and ASTS dredging systems on board the TSHD Mellina.
