Decarbonization is transforming shipboard engineering operations. MARPOL Annex VI regulations now require strict management of energy efficiency indices and operational carbon intensities.
EEXI vs. CII Compliance
- Energy Efficiency Existing Ship Index (EEXI): A technical design index measuring a vessel's carbon output per capacity-mile, requiring engine power limiters (EPL) on older hulls.
- Carbon Intensity Indicator (CII): An operational rating (A through E) indicating how efficiently a vessel actually transports cargo over a calendar year.
Key Watchkeeping Duties
Log fuel quality delivery notes (BDNs), manage cylinder oil feed rates, maintain scrubber emission logs, and track daily cargo boiler efficiency to guarantee compliance with regional emission control areas (ECAs).
