Rules and regulations outlook

Solvang expects that consolidation of data collection and compliance rules will make every vessel a target for IMO emission reduction from 2024.

DCS and SEEMP III + fuel GHG standard

As from Jan 1, 2023, SEEMP Part III is a mandatory onboard document specific to each vessel, describing how to improve the CII over the next three years.

A SEEMP III document is dynamic and must be updated in line with performance and reported measures from the ship. Beginning in 2024, it is mandatory to compute and submit the Carbon Intensity Indicator (CII) to the Data Collection System (DCS) verifier, along with the consolidated DCS data from the previous year. This submission should incorporate any applicable correction factors and voyage adjustments.

The achieved CII and its corresponding environmental grade (ranging from A to E) will be documented on the DCS Statement of Compliance (SoC). This document must be retained on the vessel for a duration of five years.

In scenarios where a vessel receives a D environmental rating for three successive years or an E rating even once, an update to the Ship Energy Efficiency Management Plan (SEEMP) Part III is mandatory.

After 2030

After the reporting year of 2030, the target specifies GHG intensity of fuel, and the values are defined as well-towake figures (not tank-to-wake). In addition all GHG gasses are included.

The EEXI and CII - ship carbon intensity and rating system

Under IMO, Marpol Annex VI, from Jan 1, 2023 all ships must calculate their attained Energy Efficiency Existing Ship Index (EEXI) and collect data to report annual operational carbon intensity indicator (CII) in order to attain CII rating A-C (compliant) to D-E (non-compliant).

The aim is to reduce specific carbon emissions in global waters by 40 % by 2030, based on 2008 projections. As for today, the vessel-specific CII is based on 2019 figures. The values from 2023-2026 have been pre-calculated, while calculations from 2026 to 2030 will depend on the planned IMO revision in 2026.

Amendments include EEDI, the Energy Efficiency Design Index, the Annual efficiency ratio (AER) deployable to ships over 50 tonnes, requiring a SEEMP (ship energy efficiency management plan) for each vessel.

A vessel rating will be based on reported fuel figures and get a score between A and E, where A is the best, C is in compliance and D and E are non-compliant scores.
