SeaARCTOS Wins LR Type Approval for CO2 Monitoring System

Lloyd’s Register Certifies ARCTOS-1 System

SeaARCTOS, a supplier of real-time emissions monitoring technology, has received Type Approval from Lloyd’s Register (LR) for carbon dioxide emissions monitoring and reporting using its ARCTOS-1™ device. According to a report by Maritime Executive, the certification confirms the system’s compliance for tracking and reporting CO2 output from ships.

ARCTOS-1™ is a MARPOL-approved, patented stack-mounted device that continuously measures CO2, sulphur dioxide, and methane exhaust emissions. The company says the unit has undergone more than 20,000 hours of at-sea testing, weighs under 3.5 kg, and is roughly the size of a shoebox. It is powered by waste heat from the exhaust stack and can reportedly be installed in under an hour without welding, cutting, or power tools.

Data Security and Anti-Tampering Features

The system includes an alarm designed to notify both port authorities and SeaARCTOS if the device is tampered with. Emissions and geolocation data are recorded at regular intervals, encrypted, and transmitted via satellite to a cloud platform. A location-locked tracking feature in the user interface is intended to guard against AIS spoofing.

Industry Commentary

Fredrik Fuglesang, CEO of SeaARCTOS, said regulatory frameworks such as FuelEU Maritime, the EU Emissions Trading System, and the proposed IMO Net-Zero Framework depend on strong enforcement mechanisms. He noted that consistent, tamper-resistant monitoring gives regulators, port authorities, and flag states evidence to act on both non-compliance and over-compliance, while also helping compliant operators avoid penalties tied to estimated rather than actual emissions.

Tianxiang Li, Global Technical Support Office Director at Lloyd’s Register, said the Type Approval offers independent assurance that the ARCTOS-1™ system is ready to support the industry as emissions regulations continue to develop.

Wider Stakeholder Uses

The source text notes that emissions performance data generated by such systems could also be useful to financiers, including Poseidon Principles signatories seeking to assess how ship-finance portfolios align with climate targets, as well as to charterers and shippers tracking Scope 3 emissions and sustainability goals. SeaARCTOS suggests real-time data of this kind could additionally reduce vessel off-hire time associated with compliance testing in port.
