DEME

Digital logbook captures business critical data

Now DEME can provide better data between vessels and good documentation to customers.

DEME specialises in mounting offshore wind turbines on a foundation that often extends many metres into the seabed below the windswept sea surface. The task requires data and documentation about geographical and geological conditions to be collected in a digital logbook. We developed this logbook in close collaboration with DEME.

Solution

Weak network in space lake

With the DEME project, we faced a new challenge compared to other IT projects: a weak or non-existent network in open sea. We had to develop an intelligent, robust and fault-tolerant solution that ensures that all DEME's vessels can collect data and automatically and continuously update each other and DEME's customers with data as soon as the network is available. The technology behind the solution is Microsoft's SQL Server Replication service.

Illumi's solution ensures that we are always up to date with all our data, so we can minimise the risk of errors and document the entire work process in detail.

Data security

Why geographical and geological data is critical for DEME

DEME is a highly specialised offshore company that has installed around half of the world's offshore wind turbine capacity. DEME operates a fleet of special, expensive specialised vessels equipped with legs that are lowered deep into the seabed. They sail to the launch site, lower the legs into the seabed and stand firmly in place to lift the one-tonne wind turbine towers onto the foundations - this is called jacking.

Illumi's solution captures vessel position logging data and jacking process data in real time, sends it to the main database on land and exchanges it between DEME's vessels and customers. The solution automatically imports and stores raw data from various sources, especially the vessel's various navigation equipment, and integrates it into the service reports that offshore crews can continuously extract from the system, even while the vessels are at sea.

Monitoring

Monitoring and registration

With the forces of nature at work, it is crucial that DEME constantly monitors and records exactly where the vessels make holes in the seabed and how deep the legs have been sunk. This information is critical for positioning the next installation or service vessel to assist in the area, and to document that the cable corridor where the submarine cable that sends the power from the offshore wind turbine onshore to consumers is located has not been crossed.

One of the biggest benefits of the project is that we can now very quickly find answers to customers' questions in our data. Of course, customers need to be sure that the installation and servicing of complicated and expensive wind turbines is carried out according to regulations to the letter.
