SeaARCTOS, a provider of real-time emissions monitoring solutions for the global shipping industry, has announced that its ARCTOS-1™ system has received Type Approval from Lloyd’s Register (LR) for Sulphur Dioxide (SO₂) emissions reporting.

Supported by a worldwide patent and MARPOL-approved technology, the system reads SO₂, CO₂, and geolocation data in real time and transmits independently to a secure cloud platform. The Type Approval confirms the accuracy, reliability, and robustness of the technology, which is the only system capable of continuous, direct, and independent SO₂ monitoring.

Fredrik Fuglesang, CEO of SeaARCTOS, commented: “Widespread compliance and enforcement challenges with global sulphur limits remain a priority for regulators. Current compliance testing is time-consuming, ad hoc, and lacking accuracy and consistency. Direct autonomous reporting means that pollution issues can seamlessly be solved for regulators, flag states, port operators and authorities, and shipowners. As regulatory oversight increases, verification systems that continuously monitor sulphur emissions will play a central role in future compliance strategies.”

ARCTOS-1™ is a compact, stack-mounted sensor that captures emissions data directly from the exhaust and transmits it securely to the cloud, independent of the vessel’s communications systems. Powered by waste heat, the carbon-neutral unit requires no welding, cutting, or external power and can be installed in under an hour. Automated operation and built-in tamper alerts notify both operators and authorities of any interference.

The technology, which has been extensively validated through more than 20,000 hours of real-world testing across commercial fleets, reduces administrative burden and eliminates off-hire time for emissions testing. By submitting its data directly to port and flag state authorities, the system helps minimise delays, improve transparency, and provide concrete evidence of compliance to cargo owners, financiers, and shareholders.

Fuglesang added: “As Emission Control Areas continue to expand worldwide, reliable sulphur monitoring is becoming more critical than ever. This Type Approval from Lloyd’s Register is a major milestone for SeaARCTOS and validates our commitment to delivering accurate, independent, and trusted emissions data.”

Beyond regulatory compliance, sulphur emissions also represent a significant human health risk. SO₂ can harm seafarers, port workers, passengers, and nearby communities, worsening existing conditions like asthma, and causing respiratory problems with long-term exposure linked to lung cancer, and potentially increase the risk of heart disease and stroke, according to the World Health Organization.
