DNK launches first-of-its-kind programme to protect vessels from electronic signal interference

DNK, the Norwegian war risk mutual insurance provider, has officially launched an industry-first programme designed to safeguard commercial vessels against the escalating threat of Global Navigation Satellite System (GNSS) signal interference. As GPS jamming and spoofing incidents rise in regions like the Baltic Sea and the Strait of Hormuz, this initiative allows shipowners to deploy advanced anti-interference technologies. By mitigating electronic warfare risks, DNK aims to ensure the safety of global maritime trade routes and protect critical navigation infrastructure.

This initiative aligns with the International Maritime Organization (IMO) guidelines on cyber risk management, specifically addressing the vulnerabilities highlighted under SOLAS Chapter XI-2 and the International Ship and Port Facility Security (ISPS) Code. Compliance departments must recognize that GNSS manipulation directly compromises the integrity of Electronic Chart Display and Information Systems (ECDIS), which are mandatory under SOLAS Chapter V, Regulation 19. Failure to address these signal disruptions can lead to significant safety non-conformities during Port State Control inspections and insurance coverage disputes.

Navigating officers and masters must now prioritize the verification of position data through secondary means, such as radar plotting and visual bearings, whenever GNSS signals appear unreliable. These professionals need to be proficient in identifying spoofing patterns and immediately reporting anomalies to the bridge team. Understanding the technical limitations of GNSS receivers is essential for maintaining situational awareness and ensuring the vessel remains on its intended track despite electronic interference in high-risk zones.
