Ship Energy Efficiency: Here is All You Need to Know

Written by Capt Rajeev Jassal on May 24, 2018

ship-energy-efficiency Energy efficiency is the big deal these days. If we use less energy, not only we save the energy but we contribute towards lesser pollution too. After all, the greenest energy is the energy you do not have to produce. As a responsible citizen of this earth, if I wish to use lesser energy than I am using now there are few things I can do. I can run my car to lesser miles than I ran last month so that I burn less fuel. This can be by using a bicycle for the shorter distance or using shorter routes for the travel I can buy a car which has better mileage than my present car. So even after running the same distance, I have now used less fuel than the last month. Ship energy efficiency is not much different than this. For a very long time, ship energy efficiency was voluntary and ship owners were expected to understand their responsibility towards energy efficiency. However, IMO felt a need to make the concept of "energy efficiency" as mandatory and thus the Annex VI of the MARPOL was amended to include chapter IV for ship energy efficiency. In this post, we will discuss everything we need to know about the requirements of the ship energy efficiency. Let us start. Ship energy efficiency When we talk about energy efficiency, there are not one but many way by which this can be...

    Dear Capt Rajeev. You are the kind of teacher or instructor which a good training institute must have. Iam really impressed with the way you provide your knowledge in simple and nice manner that anyone can understand easily. Your blogs are really good and informative specially to junior officers who are looking for answers and appearing for exams. Please continue doing the good work. You are doing a fabulous job honestly. We mostly meet people in shipping too scared to share their knowledge you are right opposite..Kudos!!!

    The full form of EEOI is "Energy Efficiency Operational Indicator" and not "Energy Efficiency Operational Index". Contents of the material otherwise are commendable.

    Thanks, but real world example would be worth to give. Our tanker vessel has attained documented EEDI as 2.632 g/tonne*nm. But our EEOI is between 7 and 12. So I wonder how comes that there is such big difference from EEDI?

    I was really lucky to have stubled upon this blog. I was looking for explanation of SEEMP and EEDI concepts and surfed through various pages, all in vain. Your explanation has been the most simple and easy to understand. Thank you so much and please keep up the good work you are doing. Thanks once again.

    Indeed, I felt lucky, too, and I am truly thankful to the author, and really glad that such brave and intelligent person exists at all. It is not easy to put all that in such a readable format, and it is twice not easy to decide to do so, and to keep doing it. Bravo.

    Thank you for your great work, Sir. Impressive. It is indeed a real problem, the language of the official sources. As usual people say, official language is rather dry, far too universal, super hard to understand, is not intuitively readable, and all that by one well known reason: to cover an ass, as some say. To be protected from misunderstandings... And no matter that understanding itself gets super awkward if possible at all. I admire your courage and your brave and responsible mission, of putting all that information your way, in simple, plain, intelligent format that makes sense. Many thanks for that. Just a little remark, about this particular blog entry, that the source was so complicated, that even you, with all your dedication, could not help it much, and I felt heavy sleepiness trying to reach the end of an article. But this is of course not your fault. Many thanks again for your outstanding attempts to help people who do want to know however would prefer to remain alive from that super dry, far too formal format that exists in the official books. I really appreciate and admire what you do, and wonder how you manage to digest all those official books without falling asleep, you must be a very strong person, maybe a saint one ;) Thank you)

    Dear Captain Rajeev, many thanks for this great article. However, I have some doubts on wordings somewhere. For me, measurements and calculations are two different things. Trying to understand the EEDI vs EEOI I came to impression that both of them were calculations, and not measurements, which logically is based on the statement that we do not measure actual CO2 emission and instead we calculate it from how much fuel was consumed per capacity mile. Therefore, very last words of your blog are confusing to me, where it says that "Energy efficient operation index (EEOI) is the voluntary monitoring tool provided by the IMO to measure and monitor the actual CO2 emission". While, based on your whole preceding explanation, I would reckon that the EEOI is a tool to calculate, and to monitor through this calculation, and not the actual emission, but still calculated emission based on actual fuel consumtion.

  • Viahak May 13, 2021
    Sir , please note , you have mentioned that seems is made mandatory as per annex 4 reg 22 . I guess you intended to write maarpol annex 6 chapter 4 regulation 22. I humbly request you to correct it. Thank you for your efforts, the article was well organized and easy to understand.

  • Shalabh Agarwal June 19, 2021
    Amazing article to get the heck of it, as it is most commonly asked by all the surveyors in MEO exams. Just that the EEOI is Energy Efficiency Operational Indicator and not Index. The surveyors in India are very particular about this as they will certainly fail the candidate if they get to hear about it.
