Classification society DNV on Saturday (23 March) published a technical regulatory news titled ‘IMO MEPC 81: Negotiations On New Ghg Reduction Requirements Continue’. The following are excerpts from the update related to bunker fuel:

The 81st session of the IMO’s Marine Environment Protection Committee (MEPC 81) continued its negotiation of GHG fuel intensity requirements, potentially in combination with a GHG pricing mechanism. 

Other important decisions include the reporting of transport work and more granular fuel consumption data in the data collection system, and approval of proposals to designate the Canadian Arctic and the Norwegian Sea as NOx, SOx and PM Emission Control Areas.

Energy efficiency

Use of ShaPoLi/EPL systems in the EEXI framework

To ensure a consistent and uniform approach to the immediate availability of power, including the power reserve, when using overridable shaft/engine power limitation (ShaPoLi/EPL), MEPC 81 revised the ShaPoLi/EPL guidelines. The revisions are based on provisions set out in IACS Recommendation 172 for systems which do not physically limit shaft or engine power and where the override of shaft power limitation can be indicated by giving an alarm. In this context, manual shaft power limitation systems can inhibit the initiation of the exceedance alarm for up to 5 minutes.

Review of the Carbon Intensity Indicator (CII)

MEPC 81 did not agree on a resolution stating that the CII rating system is currently within an experience building phase and that key elements of the system should be considered interim. Although recognizing that there are shortcomings in the CII framework, it was agreed that the CII is not a provisional measure and that such a resolution would undermine the CII. The concerns raised should be considered as part of the upcoming CII review.

Revision of the Data Collection System (DCS)

MEPC 81 adopted revised guidelines on SEEMP related to reporting fuel oil consumption per consumer type and transport work. This supports the adopted amendments to MARPOL Annex VI mandating the reporting of additional data elements through the DCS.

Carriage of biofuel blends

A proposal to allow for carriage of blends of up to 30% biofuel on bunker barges certified according to MARPOL Annex I was forwarded to the ESPH (Evaluation of Safety and Pollution Hazards of Chemicals) Working Group for further consideration.

Unified Interpretations

MEPC 81 agreed on Unified Interpretations to MARPOL Annex VI regarding:

  • the definition of heavy load carriers and
  • the application of the required EEDI to LNG carriers, cruise passenger ships, ro-ro passenger ships, ro-ro cargo ships (vehicle carrier) and ro-ro cargo ships, delivered on or after 1 September 2019.

Reduction of GHG emissions

Mid and long-term measures to reduce GHG emissions

To ensure shipping achieves the ambitions of the 2023 IMO GHG Strategy, the MEPC 80 decided to implement a basket of measures consisting of two parts:

  • A technical element,which will be a goal-based marine fuel standard regulating the phased reduction of marine fuel GHG intensity
  • An economic element,which will be GHG emissions pricing mechanism, linked directly to the GHG intensity mechanism or as a stand-alone mechanism

The measures are scheduled to be adopted in 2025 and enter into force around mid-2027.

At MEPC 81, several regulatory proposals were on the table. While there was no agreement on the package of measures, there was convergence between member states, along with agreement on an overarching structure for the needed regulatory amendments, the “IMO net-zero framework”, in MARPOL Annex VI. This is intended to form the basis for refined proposals, including possible legal language, to be discussed at MEPC 82 in October 2024.

MEPC 81 also agreed to organise the expert workshop on the further development of the basket of mid-term measures, intended to facilitate the understanding of the preliminary findings of the comprehensive impact assessment, which are expected to be available by mid-summer.

Life cycle GHG/carbon intensity for marine fuels

MEPC 81 adopted amendments to the “Guidelines on Life Cycle GHG Intensity of Marine Fuels” (LCA Guidelines), which set out methods for calculating well-to-wake and tank-to-wake GHG emissions for all fuels and other energy carriers (e.g. electricity) used on board a ship. The amendments included the quantification of parameters related to biofuel production, the evaluation of GHG intensity of electricity and the actual tank-to-wake methodologies for actual/onboard emission factors, amongst others.

The LCA Guidelines do not include any provisions for application nor requirements; they are intended to support the GHG Fuel Intensity regulation under development. 

A GESAMP Working Group was established to consider new default fuel pathway values, certification of actual well-to-tank and tank-to-well emission factors, and more general methodological LCA issues. A Correspondence Group was established to address other social and economic sustainability topics and aspects of marine fuels, for possible later inclusion in the LCA Guidelines.

MEPC 81 considered how to develop a framework for the measurement and verification of tank-to-wake emissions of methane (CH4) and nitrous oxide (N2O) in the context of the LCA Guidelines. A separate Correspondence Group was established to further progress the matter.

On-board carbon capture

MEPC 81 discussed the issue of on-board carbon capture and established a Correspondence Group to further discuss the matter and develop a working plan on the development of a regulatory framework for the use of on-board carbon capture systems.

Identification and protection of Emission Control Areas (ECAs)

MEPC 81 approved proposals to designate the Canadian Arctic and the Norwegian Sea as ECAs for nitrogen oxides (NOx), sulphur oxides (SOx) and particulate matter (PM).

For the Canadian Arctic, assuming adoption at MEPC 82, the requirements take effect as follows:

  • The 0.10% fuel sulphur content requirement takes effect from1 March 2027.
  • TierIII NOx requirements will apply to ships constructed on or after 1 January 2025, although the requirements will enter into force at the earliest on 1 March 2026.

For the Norwegian Sea, also assuming adoption at MEPC 82, the requirements take effect as follows:

  • The 0.10% fuel sulphur content requirement takes effect from 1 March 2027.
  • TierIIINOx requirements will apply to ships contracted on or after 1 March 2026; or, in the absence of a contract, keel-laid on or after 1 September 2026; or delivered on or after 1 March 2030.

Recommendations

DNV recommends that our customers take into account the work on new GHG reduction ambitions when considering energy efficiency, alternative fuels and other GHG reduction options for their existing fleet and newbuilds, and note the requirements with expected entry into force around mid-2027.

Companies operating in the Canadian Arctic and Norwegian Sea are advised to note the establishment of ECAs and the attendant effective dates of the requirements.

We also recommend signing up for our dedicated webinar, discussing the outcome of MEPC 81, taking place on 3 April 2024: https://www.dnv.com/events/mepc-81-meeting-summary-ghg- emissions-regulations-and-more/

Yang Ming orders six LNG dual-fuel, ammonia-ready containerships from Hanwha Ocean

Taiwanese shipping firm Yang Ming Marine Transport Corporation (Yang Ming) and South Korean shipbuilder Hanwha Ocean on Wednesday (2 September) signed a shipbuilding contract for six 13,000 TEU class LNG dual-fuel container vessels. 

The contract was signed by Dr. Chuck Tsai, Chairman of Yang Ming, and Mr. Charles Kim, CEO of Hanwha Ocean. The vessels are scheduled for delivery between 2028 and 2029. 

They will complement Yang Ming’s existing fleet of 10,000+ TEU vessels and serve as key vessels on East-West services, with deployment flexibility across trade lanes connecting Asia with the East and West Coasts of North America, South America, and the Mediterranean. 

Each of the six new vessels will have a capacity of up to 13,650 TEU and feature LNG dual-fuel propulsion and Ammonia Fuel Ready specifications.

“As Yang Ming transitions toward net-zero emissions, LNG provides a relatively mature and economically viable alternative fuel solution, capable of reducing greenhouse gas emissions by approximately 20%,” the company said. 

“At the same time, ammonia can serve as a carbon-free fuel by utilising converted LNG storage facilities, while offering relatively lower conversion costs and comparatively well-developed supply chains and infrastructure. The Ammonia Fuel Ready design will therefore provide Yang Ming with greater flexibility in responding to increasingly stringent international regulations on greenhouse gas emissions.”

In addition, the vessels will be equipped with Type B LNG fuel tanks with a design pressure of 1.0 bar to enhance the safety and efficiency of LNG operations, together with a range of energy-saving technologies, including Wind Shields, Rudder Bulbs, Pre-Swirl Stators, and Shore Power Systems. Smart ship technologies and cybersecurity protection features will also be incorporated to enhance operational efficiency, safety, and reliability while effectively reducing fuel consumption and greenhouse gas emissions.

Deliveries under Yang Ming’s next-generation fleet optimization plan commenced earlier this year. By 2030, a total of 24 new vessels are expected to enter service. 

This includes 18 LNG dual-fuel vessels—comprising five 15,500 TEU, seven 16,000 TEU, and the six 13,000 TEU vessels under this contract—alongside six 8,000 TEU methanol dual-fuel-ready ships.

LR, China’s MARIC unveil tanker concept ready for three future bunker fuels

Lloyd’s Register (LR) and the Marine Design and Research Institute of China (MARIC) on Thursday (3 September) have secured Approval in Principle (AiP) for a new 114,000 DWT product and crude oil tanker designed to accommodate future conversion to LNG, methanol or ammonia.

Announced at SMM 2026, the concept addresses one of the biggest investment challenges facing shipping today: the need to develop vessels and capabilities that can support a range of alternative fuel options and pathways as technologies, infrastructure and regulations evolve.

While LNG is already a mature fuel pathway, methanol and ammonia remain at an earlier stage of development, with questions around global fuel availability, infrastructure development, economics and long-term adoption.

The 114,000 DWT tanker concept has been designed as a product and crude oil carrier that can accommodate future conversion to LNG, methanol or ammonia as technologies, regulations and fuel supply chains mature. By incorporating conversion readiness at the design stage, the concept aims to reduce future retrofit complexity and provide owners with greater confidence when planning long-term fleet investments.

The design concept was reviewed against LR’s July 2026 class rules and regulations, including requirements relating to ships using gases and other low-flashpoint fuels, alongside relevant IACS Common Structural Rules for oil tankers. Final classification and statutory approval remain subject to full compliance with all applicable rules and regulations.

Theo Kourmpelis, Global Business Director for Tankers, Lloyd’s Register, said: “Shipowners are being asked to make major investment decisions today despite continued uncertainty around which fuels will dominate in the decades ahead. Alternative fuel solutions each offer potential pathways to compliance, but fuel infrastructure, regulation and economics continue to evolve at different speeds around the world.

“Designs that preserve flexibility will be critical in helping owners manage risk while preparing for multiple future scenarios.”

Si Nan, Marine & Offshore Marketing Department Vice Director, MARIC, said: “As the industry explores different decarbonisation pathways, shipowners need vessel designs that can adapt alongside technological and regulatory developments. This concept was developed specifically to provide greater fuel flexibility and long-term resilience, allowing owners to respond to changing market requirements without being locked into a single fuel strategy.

“Receiving Approval in Principle from Lloyd’s Register is an important milestone that validates the design concept and supports its future development.”

DNV: Alternative-fuelled vessel orders hit highest monthly level since October 2024

Latest data from classification society DNV’s Alternative Fuels Insight (AFI) platform alternative-fuelled vessel ordering was strong in August, with 52 new vessels added to the platform.

This is the highest monthly total since October 2024 and follows another active month in July, when 47 vessels were added to the database.

LNG-fuelled vessels accounted for the vast majority of August activity, with 46 orders recorded. The container segment led the way with 30 orders, while the car carrier segment contributed a further 12 LNG-fuelled vessels. In addition, four ethanol-fuelled bulk carriers and two hydrogen-powered bulk carriers were added during the month, as well as one LNG bunker vessel.

The strong summer performance marked a significant acceleration in ordering activity after a relatively slow start to the year. In total, 242 alternative-fuelled vessel orders have been placed in the first eight months of 2026, representing a 27% increase compared with the same period in 2025.

LNG remains the dominant fuel choice, accounting for 63% of all alternative-fuelled vessel orders registered so far this year. Container vessels represent the largest share of these LNG orders (59%), followed by car carriers (30%).

Jason Stefanatos, Global Decarbonization Director at DNV Maritime, said: “The past two months have been particularly strong for alternative-fuelled vessel ordering, with August recording the highest monthly total we’ve seen since October 2024. This has helped lift year-to-date orders to a level well above the same period last year.

“LNG remains the leading fuel choice, driven largely by activity in the container and car carrier segments. These sectors have been among the earliest adopters of alternative fuels, supported by predictable liner operations and increasing demand from cargo owners to reduce emissions across supply chains. 

“For many owners, LNG offers a combination of emissions reductions, fuel availability and future flexibility while the longer-term fuel landscape continues to evolve. 

“At the same time, the latest figures include orders for ethanol- and hydrogen-fuelled vessels, highlighting that owners continue to explore a range of decarbonization pathways. Different segments are making different fuel choices, but the overall level of activity demonstrates continued investment in lower-emission shipping.”
