The international maritime industry is racing against time to comply with the expanded Data Collection System (DCS) requirements. Germany-based CM Technologies has issued a warning to shipowners and operators, emphasizing that data required for 2027 reporting must be collected starting from the very first days of 2026.
Although the new regulation—covering all ships of 5,000 GT and above engaged in international voyages—officially entered into force in August 2025, the reporting timeline is based on a full calendar year.
The updated rules require not only total fuel consumption data, but also far more detailed and disaggregated information, including fuel usage across different onboard systems, distance traveled, and voyage duration.
Experts highlight that the new system represents a shift from “estimation and reconciliation” to “direct measurement.” Incomplete or inconsistent datasets may prevent vessels from obtaining their Statement of Compliance.
