BIMCO ‘concerned’ on IMO suggestion to amend sulphur testing and sampling regulation

New suggestion can cause confusion between the ship, bunker supplier, time charter etc, especially if the testing results turn out to be different, said BIMCO.

Christian Bækmark Schiolborg, Manager, Marine Environment at BIMCO on Monday (16 November) published an article explaining why BIMCO is ‘concerned’ with the proposed procedure for ‘On board sampling’ to be used in determining compliance with sulphur regulations as the International Maritime Organization (IMO) prepares to discuss amendments to MARPOL Annex VI this week:

While shipowners have been focused on the 2020 sulphur regulation which entered into force on 1 January 2020 due to safety concerns, IMO members states have had their eyes on the procedures that control whether ships are carrying low-sulphur fuel oil in accordance with the new regulations.

In connection with the amendments to MARPOL Annex VI a few definitions will come in handy:

  •  In-use sample, defined as the sample of fuel oil in use on a ship. It can for example be drawn from the fuel oil line between the service tank and an auxiliary engine.
  •  On board sample, defined as the sample of fuel oil intended to be used or carried for use on board a ship. It is drawn directly or indirectly from fuel oil tanks.

According to the new regulation, authorities including Port State Control are thus given explicit authority to draw oil samples from the ship’s fuel oil tanks.

BIMCO is concerned with the suggested procedure for ‘On board sampling’ to be used for determining if the ship is in compliance with the sulphur regulation, since the only truly homogenous and representative fuel oil sample is the MARPOL sample (MARPOL delivered sample). The new suggestion could cause confusion and uncertainty between the ship, bunker supplier, time charter and other stakeholders, especially if the testing results turn out to be different, BIMCO believes.

Direct samples drawn through the sounding pipe or the manhole cannot in BIMCO’s view be considered homogenous and representative for the sulphur content in the fuel oil tank. This is recognised (but also disregarded) in the circular on early application of the verification procedures for a MARPOL Annex VI fuel oil sample (MEPC.1/Circ.882 ):

“The in-use or on board fuel oil sample, as appropriate, shall be used to verify the sulphur content of the fuel oil as represented by that sample of fuel oil at the point of sampling.”

This means that a fuel oil sample drawn by PSC is only representative of the fuel oil at the level or point of suction, but not representative of the fuel oil in the tank.

Indirect samples drawn by using the fuel oil transfer pump, cannot be used either, since the sample is not homogenous and representative of the sulphur content in the tank. Since the transfer pump’s suction is placed in the bottom of the fuel tank, BIMCO fears that such samples would show wrong results even if the sulphur content of the fuel oil is actually compliant.

This leads to the fact that the only fuel sample truly homogenous and representative of the sulphur content that is available today, is the MARPOL sample because it is drawn over the entire bunker operation.

Safety concerns in case of direct sampling from fuel oil tanks

A normal fuel oil tank only has two openings, the manhole, for inspection when the tank is empty, and the sounding pipe. Fuel oil tanks on existing ships are not constructed with designated sampling points.

The manhole should never be opened while there is fuel oil inside the tank. Fuel oils are stored at high temperatures and it is consequently unsafe for the people taking the sample.

The MARPOL (delivered) sample is still essential

The statutory fuel verification procedure for MARPOL Annex VI fuel oil samples is being updated to include the new fuel oil samples and making the text of the circular on early application of the verification procedures for a MARPOL Annex VI fuel oil sample mandatory. 

More information can be found here interpretation of the discord between MARPOL and commercial fuel samples.

Compared to the current verification procedure, MARPOL (delivered) samples will in the future be tested without taking the Reproducibility (R) of the test method into consideration. This means there will be no test margin and thus, the test result of a MARPOL sample (average of two tests by the same laboratory) must not exceed 0.50% m/m sulphur.

For ‘In-use’ and ‘On board’ samples, the Reproducibility (R) of the test method, in accordance with ISO 4259-2:2017, should be taken into consideration when assessing whether the test result is acceptable or not. This means that the test result, from the fuel oil samples drawn by PSC, shall be considered acceptable if the sulphur content does not exceed 0.53%.

This small but essential difference between the verification procedure for MARPOL samples and samples drawn by PSC was agreed by IMO deliberately. The difference is intended to ensure that ships are not unfairly penalised for marginal exceedances due to factors outside the ship’s control. Time will show if this is sufficient to avoid that different conclusions are drawn from the different types of samples.

In the end we should not forget that it is still the responsibility of the supplier to deliver fuel oil which is compliant with the statutory sulphur content limits i.e. 0.50% or 0.10% m/m.

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.”
