Guidance on the application of correction factors and voyage adjustments for calculation of attained Cll
Year: 2023 Language: English Author: Lloyd's Register Genre: Presentation Format: PDF Quality: eBook Pages count: 9 Description: The Carbon Intensity Indicator (CII) requirements for ships have been introduced by IMO as a short-term GHG reduction measure. IMO has also allowed for voyage adjustment and correction factors for certain ship types, operational profiles and/or voyages with a view to enhancing, as appropriate, the CII Guidelines (G1). The corrections factors and voyage adjustments which may be applied to the calculation of the attained annual operational carbon intensity indicator are described in the CII Guidelines (G5). A correction factor means a factor in the numerator or denominator of the CII formula which adjusts the calculation of the attained CII. Voyage adjustment deducts relevant fuel consumption, as well as the associated distance travelled from the calculation of attained CII for a defined period subject to certain threshold conditions being met. IMO has prescribed a specific formula for CII calculation to be used when the corrections factors and voyage adjustments are applied. Proper data and supporting evidence need to be collected for submission to the verifier if the corrections factors and voyage adjustments are applied. The purpose of this guidance is to provide practical tips on how and what data is to be collected and evidence obtained for the application of the corrections factors and voyage adjustments. The information provided in this guidance is not intended to replace the relevant guidelines and regulatory documents published by IMO. It is instead complementary and has been prepared as a handy guide to assist persons involved with IMO DCS data collection and CII calculations.
