“We Are Doing Too Little with the Data We Collect!”

Interview with Andrea Grün, Senior Principal Engineer for electrical systems and automation at DNV GL

What would happen if there were a chance to deeply access the engine room level – even from afar? Completely new challenges for approvals and certification of components and systems have arisen for international classifying agencies because of this scenario. Agencies, like the Norwegian-German DNV GL, must factor cybersecurity for operational safety on board ships into their certifications. As Andrea Grün, Senior Principal Engineer for Electrical Systems and Automation DNV GL in Hamburg explains, remote access is the primary cause for concern.

In mechanical engineering, remote connections for remote maintenance, system optimization or streamlined maintenance cannot be wished away. From the standpoint of a classification agency, what do you consider important in network connections from ship to land?

Grün: System manufacturers want to equip their systems with remote access because this eases maintenance and service. We have established corresponding guidelines for such tasks. We have considered, for example, that there should be no updates while a ship is underway. We are not the police; however, we do prohibit access from land to the systems when the ship is at sea.
