CII insights on the RightShip Platform 
CII insights on the RightShip Platform 
Updated over 5 months ago

From June 5th, 2024, RightShip users will see a vessel’s annual and estimated CII displayed alongside the GHG Rating.  

Why CII matters

CII is the IMO’s energy efficiency rating for vessels. The rating has flaws and is likely to undergo a major review soon, but it is now a vital metric for the industry to understand. We are introducing CII insights onto the RightShip Platform to enhance transparency, to help users to see how a vessel’s CII can be understood in relation to its GHG Rating, and to facilitate better-informed commercial conversations.   

Submit your annual CII

Users can now submit annual CII on the RightShip Platform, alongside EEXI, EEDI, EVDI, and energy-saving devices. Visit our Environmental Review instructions to learn more. Vessels with unsubmitted ratings will have their CII will greyed out after May 31st, in line with the IMO’s CII submission deadlines.  

CII, GHG Rating, and vetting

There is no relationship between a vessel’s CII and GHG Rating. The annual and estimated CII Ratings are for insight only and will not be used in RightShip’s vetting rules or Baseline Criteria.  

Platform updates: the Carbon Intensity Indicator page

  1. The annual CII rating is displayed on the vessel header as a mirror image of the GHG Rating, with identical colour coding on the A-E scale. This encourages understanding of both the design and operational aspects of a vessel.  


    If the vessel has not submitted any CII Rating or keeping in line with the regulation that each ship needs to have its CII Rating issued by 31st May of the subsequent year, the CII flag will turn grey. 

  2. EEXI information is now a sub-section with the GHG Rating page. 

  3. The Operational Metrics page is now titled CII Rating, and hosts CII-related information. 

  4. A CII filter has been added to the Vessels page, allowing users to filter and select vessels based on CII.  

Estimated CII Rating graph:

An estimated CII Rating graph has also been made available in partnership with ZeroNorth. The intent in this design is to help users on the RightShip Platform be directed to the appropriate pages for further follow-up and insights from ZeroNorth. 

Below features of the graph will be helpful for its understanding: 

  1. The data in this graph is expected to appear two weeks delayed as there is a curation period involved in ZeroNorth’s model before it flows to the RightShip’s Platform. 

  2. The scatter plot refers to non-continuous weekly block i.e non-cumulative 7 days. The tooltip on the graph shows the related week’s estimated CII Rating and value, distance, average speed, and fuel consumption. 

  3. The continuous curve in the graph is cumulative week till date (YTD) with the related tooltip displaying corresponding CII Rating and value. 

  4. Since the model needs AIS data, there might be some vessels where if data is unavailable their rating may not be continuous or displayed. 

  5. This is a six-month trial period running through December 2024 during which this service will be offered at no additional charge. Further activation beyond this trial period is under review and will be updated in due course.

FREQUENTLY ASKED QUESTIONS  

Q.1 Can a good Annual CII Rating improve a vessel’s GHG Rating or vice versa?  

A. There is no relationship between the two systems. A vessel’s CII does not affect

RightShip’s GHG Rating. The GHG Rating is a design-based peer rating system while the CII is an operational metric as per IMO defined benchmarks. However, a poor CII rating might encourage a vessel owner to invest in energy saving devices and equipment to improve its performance which can lead to an improved GHG Rating once reported to and verified by RightShip. 

  

Q.2 Will Annual CII Rating be used in RightShip’s vetting rules?  

A. No. RightShip believes that CII in its current structure is not suitable for vessel selection through Rightship’s vetting rules.  

  

Q.3 What is ZeroNorth’s estimated (Live) CII’s update frequency?  

A. ZeroNorth’s data is calculated at weekly level. The data based on AIS and ZeroNorth’s fuel consumption data model is curated and released with a two-week delay, hence the related graph will always be missing the latest two weeks after each weekly refresh.  

Q.4 If RightShip believes in CII not delivering the expectations in current structure, what purpose does hosting a live estimated CII Rating graph serve? 

A. Annual CII being a regulatory system under the IMO’s MARPOL Annex VI makes it availability as an emission metric inevitable and hence hosting it on the Platform enables its transparency. 

CII has started to be used in commercial agreements in the market, albeit only a few. This has the potential to gain more acceptance with time as IMO evolves the CII regime. This can be seen through the clauses developed by BIMCO which indicates live CII monitoring between charterer and operators in a commercial set-up. Hence, this integration promotes transparency where there is a gap between the commercial entities.
