Compliance Is Arriving — IMO Sub-Committee Outcomes for 2027
By Vignesh D. · January 18, 2026 · 6 min read
The CCC sub-committee outcomes from late 2025 telegraph a regulatory floor for vehicle-deck monitoring. Operators that wait to retrofit will be behind a hard date.
The IMO sub-committee on Carriage of Cargoes and Containers (CCC) met in late 2025 and the outcome documents are now in member-state circulation. The direction of travel for vehicle-deck fire safety is clear, and the timeline is tighter than most operators are pricing in.
What is on the table
- Continuous monitoring of weather-deck and enclosed cargo spaces carrying vehicles with traction batteries.
- Time-stamped retention of detection data for casualty investigation.
- Demonstrable detection-to-alert intervals against staged test scenarios.
Member-state implementation is expected to converge around 2027 H2 for newbuilds, with retrofit grace periods of 24–36 months for existing tonnage.
What this means for fleet planning
A 36-month retrofit window sounds long until it is mapped against drydock cycles. For a fleet of 30 PCTCs on 30-month dock cycles, that is roughly one slot per ship — and yard capacity for the work is already tightening for 2027–2028.
