EEDI: Energy Efficiency Design Index, developed in 2013
EEXI and CII: Energy Efficiency Existing Ship Index and Carbon Intensity Indicator, developed in 2021 (entering into force in 2023)
SEEMP:Ship Energy Efficiency Management Plan(船舶能效管理計劃)
關于能效管理計劃SEEMP,簡而言之:
1、400總噸以上的船舶,需要編制SEEMP Part I,簽發(fā)IEE證書;(2013年實現(xiàn))
2、5000總噸以上的船舶,需要分別編制SEEMP Part II(船舶燃油消耗數(shù)據(jù)收集計劃)和SEEMP Part III(船舶營運碳強度計劃),并由船旗國或船級社分別簽發(fā)COC證書;(Part II 2019年1月1日前實現(xiàn),Part III 2023年1月1日前實現(xiàn)。)
3、船旗國或船級社,基于上述兩個COC和收集到的船舶上一年度相關數(shù)據(jù),簽發(fā)有效期一年的SOC(Statement of Compliance-Fuel Oil Consumption Reporting and Operational Carbon Intensity Rating),新的SOC應包括SEEMP Part II和Part III兩部分內容,證書格式如下:
2021年6月10日至17日以遠程視頻會議方式召開的MEPC 76會議,通過了MARPOL附則VI修正案,對SEEMP提出了新的要求,即對于5000總噸及以上且屬于本附則規(guī)定的一種或多種類別的船舶:
在2023年1月1日或以前,SEEMP應包括:
1 用于計算船舶達到的年度營運碳強度指標(CII)的方法和用于向船舶主管機關報告該值的過程的描述;
2未來三年的要求的年度營運CII;
3 記錄如何在未來三年達到要求的年度營運CII的實施計劃;和
4 自我評估和改進程序。
SEEMP Part III旨在幫助船東達到所要求的CII。這是一份動態(tài)化的文件,需要定期更新和修訂,以反映不斷變化的船舶排放性能及所需采取的措施。
CII
Redolution MEPC.304(72) The initial Carbon Intensity of international shipping to decline IMO Strategy on Reduction of GHG Emissions from Ships contains levels of ambition, the second of which is:
Carbon intensity of international shipping to decline
To reduce emissions per transport work, as an average across international shipping, by at least 40% by 2023, pursuing efforts towards 70% by 2050, compared to 2008.
Carbon intensity is defined as emissions per tranport work.
CII: Operational carbon intensity indicator, in order to distinguish it from EEDI and EEXI which are technical indices calculated using fixed design parameters.
Demand-based CII which is calculated based on the variable actual or estimated mass or volume of cargo carried on board.
Supply-based CII where the fixed capacity of the ship (in DWT or GT) is taken as a proxy of the actual mass or volume of cargo.
Since cargo mass is not reported to the IMO, nor to public databases, reliable baselines of demand-based CII may not be derived, therefore the IMO uses supply-based CII in its regulation.

CII 對船舶意味著什么?
自 2019 年以來,IMO根據(jù)自己制定的船舶燃油消耗數(shù)據(jù)收集系統(tǒng)(DCS)收集各個船舶的燃料消耗、航行距離和航行小時數(shù)據(jù)。然后,IMO根據(jù)這些數(shù)據(jù)把船舶分成A、B、C、D、E的 5個等級,其中A級最為環(huán)保,污染最嚴重的獲E 等級。當前的要求是:A、B、C屬于滿足要求,D、E將被視為不合規(guī)。如果一艘船的CII評級為E或者連續(xù)三年評級為D,則該船舶公司將被要求制定糾正計劃并提交修訂后的SEEMP。
盡管CII評級為E或者連續(xù)三年評級為D的船舶,至少目前不會或很少會使船舶受到懲罰,但是,所有航運利益相關者,如租船人、港口、保險公司、金融機構和引航等,或都將關注船舶的CII評級,并產(chǎn)生一定影響。另外,在PSC檢查時,船舶將會受到更多關注,增加滯留風險。
