Classification society DNV on Wednesday (11 December) published a Technical and Regulatory News  highlights the importance of determining whether alterations to ships will be considered a major conversion under MARPOL Annex VI: 

The EEXI requirement came into effect on 1 January 2023, and all affected ships should now comply. To maintain compliance, any ship undergoing changes that affect its EEXI and/or EEDI may need to recalculate these. This statutory news outlines impacts on and necessary actions for energy efficiency certification following ship modifications.

What is a “major conversion”?

Under MARPOL Annex VI (Regulation 5.4), the Energy Efficiency Existing Ship Index (EEXI) and, if relevant, the Energy Efficiency Design Index (EEDI), must be recalculated and surveyed on board in the event of a major conversion, as defined in Regulation 2.2.17.

A major conversion includes:

  • Any substantial change in hull dimensions or capacity, except a decrease of assigned freeboard if no other alterations to the ship structure are made.
  • Any substantial increase in total engine power for propulsion (5% or more).
  • A change of the MARPOL ship type as noted on the International Energy Efficiency Certificate (IEEC).
  • A conversion intended to substantially prolong the life of the ship.
  • Significant modifications that would require the ship to meet new requirements as if it were newly built.
  • Any substantial alterations impacting energy efficiency, such as modifications that could cause the ship to exceed the applicable required EEXI or EEDI (if relevant).

If it is unclear whether a conversion is considered major, the flag administration will have the final say. For typical scenarios that may constitute a major conversion, please see DNV’s overview Re-certification of the EEXI.

EEDI compliance for extensive major conversions

If a major conversion is so extensive that the ship is considered newly constructed, the flag administration may require the ship to meet the EEDI requirements by using the reduction factor corresponding to the contract date of the conversion. In such cases, a ship originally subject only to the EEXI will also need to comply with the EEDI, and a ship already subject to the EEDI may face a more stringent EEDI requirement (a higher EEDI phase). However, most major conversions will not fall into this extensive category.

Approval of EEXI/EEDI Technical File

If the conversion is considered major, the EEXI and, if relevant, the EEDI should be recalculated, and the new Technical File(s) submitted for approval. Any necessary actions to meet the requirements should be included in the project, such as limiting the propulsion power. If installing a new or adjusting an existing overridable power limitation, an approved Onboard Management Manual (OMM) for Shaft Power Limitation (SHaPoLi) or Engine Power Limitation (EPL) will be required.

For ships subject to the EEDI, if the new attained EEDI is equal to or less than the new required EEXI, it can be considered the new attained EEXI. Consequently, the attained EEXI will be verified using the EEDI Technical File, eliminating the need for a separate EEXI Technical File.

Approval is managed through DNV’s digital EEXI self-service tool on the Veracity platform. This tool can be accessed via the “Vessel Services” tab under “Fleet Status”. A detailed guideline on how to use the tool is also available on the same page. The only exception is for MARPOL ship type changes, which are currently not supported by the tool.

Survey and certification after ship alteration

Upon completing the alteration, a survey shall be conducted to confirm the new EEXI and, if relevant, the EEDI. This survey will also verify any measures installed due to the new calculations, such as power limitations. Once the survey is completed, a new IEEC will be issued to reflect the updates.

The validity of the IEEC will be verified during annual statutory surveys. Additionally, the PSC guidelines include checks to determine if the ship has undergone a major conversion or if there have been changes affecting aspects covered by the EEXI or EEDI Technical Files.

EEXI/EEDI calculations for non-major conversions

Conversions that have an impact on energy efficiency, but which are not considered major conversions, will not require re-approval of the EEXI/EEDI Technical File(s) or a new IEEC. However, re-approving the Technical File(s) and issuing a new IEEC should be considered to reflect, for example, an improved energy efficiency index, especially in cases where SHaPoLi/EPL installations may be removed, or the power limitation is reduced.

SEEMP/CII for ship alterations

When making alterations, it is important to consider their impact on the SEEMP III and the CII calculation as well. An alteration may affect the SEEMP III, which outlines the future attained and target CII as well as future measures in the three-year implementation plan. Key parameters used in the CII equation – such as MARPOL ship type, deadweight and gross tonnage – are particularly important. Therefore, the DCS verifier should be informed in order to make the necessary updates and correctly verify the CII to assign an appropriate rating.

When DNV serves as both the class and DCS verifier, essential data for the CII calculation will be automatically captured upon updating the IEEC. For ships not classed by DNV but where DNV acts as the DCS verifier, a copy of the new IEEC, along with the new load line certificate if there is a change in deadweight, should be submitted via DATE.

Recommendations

When planning any alterations, it is essential to determine early on whether the changes will be considered a major conversion under MARPOL Annex VI. Assess the potential impact of the alterations and ensure that the ship remains compliant upon completion of the alteration.

China: Zhoushan Port achieves 7.26 million mt annual bunker volume for 2024

Zhoushan Hi-Tech Zone Administrative Committee on Friday (10 January) said Zhoushan, the fourth largest bunkering port of the world, delivered 7.26 million metric tonnes (mt) of marine fuel in 2024.

This marked about a 3% increase from 7.04 million mt in 2023. 

The committee also highlighted the progress Zhoushan Port has made in the past year including actively planning to build an alternative fuel bunkering centre.

It has successfully obtained approval for the national biodiesel promotion and application pilot project. The construction of a project to produce an annual 1 million mt of marine biodiesel has begun.

The first methanol vehicle-to-ship pilot was carried out, and the first methanol bunkering barge in Zhoushan was officially built and is expected to be put into use by the end of 2025.

The port has also improved the fuel supply efficiency of various bunkering anchorages in Zhoushan including Tiaozhumen Anchorage adding three bunkering anchorages on top of the original five and has successfully carried out night bunkering operations. 

Xiushandong and Mazhi anchorages have added a total of three new bonded bunkering anchorages, which can implement all-weather and fully automatic anchorage reservations, and provide advance reservations and priority refueling services for large ships and large orders.

The committee also highlighted Dong Fang Zhao Yang becoming the first domestic bunkering barge to obtain the mass flow meter system certification under the ISO22192:2021 standard. The barge conducted a successful pilot for the bunkering of bonded fuel oil using a mass flow meter at Xiushandong Anchorage on 9 December. 

A spokesperson of the committee said Zhoushan will focus on promoting alternative bunker fuels such as biofuel and LNG and accelerating the completion of methanol refuelling safety assessments.

Rasmus Stute from DNV interviews Sameer Kalra, President of the Marine Division and Executive Vice President at Alfa Laval, on key industry trends including the company's innovative approach to the energy transition, emphasizing fuel-agnostic solutions, energy efficiency and close collaboration with third parties to meet future challenges:

We met recently at the SMM trade fair, always a really important date on the shipping calendar. What were your takeaways?

The first thing that stood out to me was that energy efficiency seems to be really high on the agenda, alongside LNG as an alternative fuel. Secondly, digitalization seems to be much more in focus than just a couple of years ago. This is why it is so great to come to these trade shows; you can hear what the industry’s talking about and it really helps to calibrate your own views.

At SMM, we launched our latest Maritime Forecast to 2050, which focuses on the building blocks needed for the energy transition in shipping. From Alfa Laval’s perspective how are you going to respond to the energy transition? Is this a significant challenge or something you’ve already anticipated?

The one thing that Alfa Laval is absolutely known for is being innovative from the beginning and that’s still part of the company’s DNA. So when we started working around decarbonization and the energy transition roughly five or six years ago, we took the position that as Alfa Laval we needed to put our money where our mouth was. And, instead of just telling others to decarbonize, we also set some goals for ourselves for 2030. Right now, we expect to meet our Scope 1 and 2 net zero targets ahead of schedule. (PS: After this interview took place, Alfa Laval announced an updated goal to achieve net zero in its own operations by 2027, covering Scope 1 and 2 emissions.) 

However, challenges remain, particularly supporting customers in areas outside our direct control, such as fuel choice. Shipowners have a tough challenge, finding a vessel design and choosing a fuel that is economically viable, commercially attractive and future-proof for the next 20–25 years. Recognizing this complexity early on, we positioned ourselves to support shipowners with versatile, future-ready solutions. In particular, one major initiative has been to ensure our product portfolio is fuel-agnostic

Additionally, we have prioritized the development of new platforms focused on energy efficiency. Another key step has been the acquisition of StormGeo, which, whilst unconventional for a company like Alfa Laval, aligns with our strategy to address the evolving energy efficiency and sustainability demands of the maritime industry. Ultimately, our commitment is to provide solutions that enable both immediate and long-term decarbonization goals.

You mentioned key elements like energy efficiency and fuel flexibility, and you have set up your company to address these challenges. Looking ahead to 2030, what do you envision will be your most important products to support customers with these trends?

It is challenging to be definitive about specific products, but we can identify trends. Our energy efficiency portfolio will play an increasingly important role, even more so than it does today. Transitioning to clean fuels will also grow in importance. If I were to highlight one area, it would be energy efficiency over the short term. 

Given the challenges in scaling up the supply of green methanol and ammonia by 2030, boosting energy efficiency becomes an essential, immediate necessity for the industry. At Alfa Laval, all three of our divisions – Marine, Energy, and Food and Water – will contribute to these efforts. In the near term, we will focus on enhancing energy efficiency in existing systems whilst introducing new, innovative energy efficiency platforms across our product portfolio to support our customers in navigating this energy transition.

I’ve a follow-up question on the energy transition. How do you feel about the role of carbon capture and storage in this process?

From our perspective, carbon capture and storage (CCS) is set to play an important role, particularly on the energy side. However, the role of onboard carbon capture specifically is less clear. These are two different challenges and we need to approach them with an open mind. For instance, it’s possible that LNG could be a transitional fuel that achieves a 20% reduction in emissions. If onboard carbon capture technology could add another 10–15% reduction on top of that, it might be a viable step forward. 

However, there are still many questions to address. We need to solve challenges related to the footprint of onboard carbon capture systems, as well as their cost-benefit ratios. These are critical factors that must be worked out before onboard carbon capture becomes a widespread solution. That said, I have confidence in the ingenuity of the maritime industry, and I am optimistic that we will find ways to overcome these challenges. 

And whilst there are still questions to answer, I firmly believe that carbon capture and storage, both on land and onboard, could make a significant contribution towards accelerating the energy transition.
