The International Bunker Industry Association (IBIA) on Thursday (19 December) published an industry article to encourage IMO 2020 compliance:

One of the concerns around implementation of the 0.50% sulphur limit has been, and continues to be, the need for effective enforcement to ensure a level playing field. Of course, we need deterrents, but IBIA would like to stress that while enforcement is up to the MARPOL Annex VI signatory states, compliance is up to the industry. Enforcement will probably be weak in some parts of the world, but that should not discourage industry from complying. After all, just because police aren’t constantly watching us, most of us do not commit crimes. That would make us criminals. We abide by the law because we want to be good citizens.

Sure, many drivers will break the speed limit if they know there is little or no risk of getting caught. We know that speed cameras help, as does the knowledge that police may show up and do speed controls at random. Some parts of the world already have similar controls in place to monitor compliance with sulphur limits, including ‘sniffer’ devices that play a similar role as speed cameras, and random spot checks on fuel samples from ships and/or bunker suppliers to test for sulphur. The European Union has established such regimes under the EU sulphur directive to uphold the 0.10% sulphur limit in emission control areas and for ships at berth in EU ports. It has worked: compliance levels with the 0.10% sulphur limit in EU ports and ECAs has been good.

Many countries, even those that are party to MARPOL Annex VI, will not be able to enforce because they have haven’t transposed the regulation into national law. In some countries, port State control (PSC) will lack resources such as testing equipment, personnel and training to enforce effectively. However, the IMO is assisting with capacity building and training, and workshops have already been delivered with the support of Denmark and the World Maritime University.

In the meantime, those countries that have experience and/or resources to undertake thorough PSC checks may help by taking on a heavier burden in policing the IMO 2020 regulation, and because shipping is so international, most ships will eventually be checked.

The IMO has given us a tool that means breaking the rule will be harder than simply breaking the speed limit on the highways when there is no speed controls or cameras: the carriage ban.

Apart from ships that have an approved exhaust gas cleaning system (EGCS) or scrubber, use of fuel exceeding 0.50% sulphur will be prohibited from 1 January 2020. That is hard to police and enforce on the high seas, although the ship’s flag State (if it is a signatory to MARPOL Annex VI) has a responsibility to ensure the ship complies. However, as of 1 March 2020, ships without scrubbers won’t even be allowed to carry fuel exceeding 0.50% in their fuel tanks. That will make enforcement significantly more straightforward as authorities, including port State control officers, only need to prove that the ship is carrying non-compliant fuel. This will start by checking documentation and, if they suspect non-compliance, they can take samples for testing.

No ship without a scrubber should have a bunker delivery note (BDN) indicating that it has lifted fuel above 0.50% sulphur after 1 January 2020, as that would mean both the bunker buyer and the supplier have acted in contravention of MARPOL Annex VI.

Ships must have BDNs for each product supplied to the ship documenting the sulphur content. They must also carry an International Air Pollution Prevention (IAPP) Certificate and, if using EGCS/scrubbers to comply, IAPP supplement showing it has “an equivalent arrangement approved in accordance with regulation 4.1 that is at least as effective in terms of SOx emission reductions as compared to using a fuel oil with a sulphur content limit value of 0.10% m/m (in ECA) or 0.50% m/m (outside ECA)”.

Appendix V of MARPOL Annex VI prescribes information to be included the bunker delivery note. This includes the name and IMO Number of the receiving ship, actual sulphur content and a declaration signed and certified by the fuel oil supplier’s representative that the fuel oil supplied is in conformity with regulation 18.3 and that the sulphur content of the fuel oil supplied does not exceed the relevant MARPOL Annex VI limit value, i.e. the ECA limit (0.10%) or the limit outside ECAs, i.e. 0.50% as of 1 January 2020.

There is a provision in the regulation regarding the BDN for supplying fuel to “the purchaser’s specified limit value, as completed by the fuel oil supplier’s representative and on the basis of purchaser’s notification that the fuel oil is intended to be used” either “in combination with an equivalent means of compliance” – in other words a scrubber – or “is subject to a relevant exemption to conduct trials for sulphur oxides emission reduction and control technology research”.

The regulation is clear. It requires bunker suppliers, if asked to provide fuel exceeding the 0.50% sulphur limit, to do so only on the basis of receiving a notification from the buyer that the fuel is intended to be used compliantly. There is no requirement on the supplier to check if this is the case – only to obtain a ‘notification’.

Bunker suppliers could, however, play a more active role in ensuring only ships with scrubbers, or a valid exemption to conduct trials, will receive high sulphur fuel oil (HSFO). They can, for example, check the IMO’s Global Integrated Shipping Information System (GISIS) and look for the MARPOL Annex VI module. Within this module, there is a tab for Regulation 4.2: equivalent compliance method; where you can search for ships by their IMO number to see if they have an approved scrubber. If the ship’s scrubber is very new, it is possible that it hasn’t yet been entered into the GISIS system (this is the responsibility of its flag State). The supplier could, in that case, ask for a copy of the IAPP supplement showing that the ship has an approved scrubber installed, or documentation proving that it has a valid exemption to conduct trials. Some suppliers are doing this as part of their counterparty due diligence checks.

The only other reason a ship without a scrubber could legitimately lift fuel above 0.50% sulphur would be due to a genuine non-availability of compliant fuel. If the ship has not been able to source compliant fuel it needs to provide sufficient evidence for that to its administration (flag State) and relevant authorities at its next port of call. The IMO 2019 Guidelines on consistent implementation of 0.50% sulphur limit under MARPOL Annex VI includes a standardised fuel oil non-availability report (FONAR).  The FONAR is not an exemption, but authorities are expected to take it into account as a mitigating circumstance and could decide that the ship won’t be penalised for using non-compliant fuel when, despite best efforts, it wasn’t able to source it.

Some think this is unlikely to occur because of widespread global availability of MGO that meets the ECA sulphur limit, and a 0.10% sulphur product is, of course, also compliant with the 0.50% sulphur cap.

Let’s not forget that MARPOL Annex VI is there to protect our fellow citizens and our children by reducing harmful air pollution. Flouting the rules means those benefits would be lost. We need good citizenship and sensible actions to support the continuing improvement of our environment while ensuring that shipping continues to meet the need for global transportation of goods and maritime services for all.

VO Chidambaranar (VOC) Port Authority on Friday (29 May) said it has signed a Memorandum of Understanding (MoU) with India’s ammonia producer AM Green Ammonia to collaborate in the development of a green ammonia production plant.

The plant will have a capacity of one million tonnes per annum (MTPA) at Tuticorin.

The initiative also includes development of green ammonia handling, storage and bunkering infrastructure, pilot bunkering operations, safety procedures and training programmes. 

The project is expected to support the development of green fuel corridors connecting VOC Port with major ports in Europe and Asia, thereby strengthening India’s position in the global green fuels value chain.

VOC Port also signed a Memorandum of Understanding (MoU) with Bureau Veritas (India) Pvt. Ltd., to collaborate on Green Port certification, emissions accounting, ESG reporting, safety validation, development of green bunkering practices, and establishment of a Centre of Excellence for green fuels and sustainability.

The port also plans for an upcoming 750 m³ green methanol bunkering facility.

Recent global regulations have significantly reduced sulphur emissions from ships, helping to improve air quality in coastal regions – confirmed by a recent international study led by researchers at the National Centre for Atmospheric Science. 

The research, published in Environmental Science: Atmospheres, used aircraft and ground-based instruments to measure sulphur dioxide and nitrogen oxides emitted by ships in the North-East Atlantic and European coastal waters between 2019 and 2023.

The team found that the average sulphur content in ship fuel dropped nearly tenfold in open ocean areas following the International Maritime Organization’s 2020 regulation, which capped sulphur content in marine fuel at 0.5%. 

Before the change, many ships exceeded the previous 3.5% limit. After 2020, only a small number of ships were found to breach the new standard.

In European sulphur Emission Control Areas (SECAs), such as the English Channel and the Port of Tyne, sulphur levels were even lower – well below the stricter 0.1% limit. Interestingly, ports outside these zones, like Valencia in Spain, also showed low sulphur levels, likely due to EU rules requiring cleaner fuel when ships are docked for extended periods.

This is the first study to use aircraft-based measurements and predictions from the Ship Traffic Emission Assessment Model (STEAM3) to assess ship emissions outside of sulphur control zones since the 2020 regulation came into effect. The findings support the widely held view that ships now emit around seven times less sulphur than before the rule change – an important step toward cleaner air and healthier coastal environments.

IBIA Annual Convention 2025: ‘Exciting times’ for post IMO 2020 bunker suppliers, states Equatorial

Choong Sheen Mao, Chief Operating Officer, Equatorial, describes to Manifold Times the pre/post IMO 2020 challenges and evolution of bunker suppliers.

The International Bunkering Industry Association (IBIA) will be hosting its flagship Annual Convention in Hong Kong at the Hong Kong Convention Exhibition & Convention Centre between 18 to 20 November 2025, as part of Hong Kong Maritime Week.

Choong Sheen Mao, Chief Operating Officer, Equatorial Marine Fuel Management Services (Equatorial), speaks to bunkering publication Manifold Times about the challenges of a post IMO 2020 bunker supplier.

MT: How does Equatorial continue to offer customer assurance and maintenance of marine fuel quality to ISO8217 standards despite increasing complexity of bunker fuel blends?

We maintain our focus to provide compliant, quality and competitively priced products to our customers. There is no shortcut. We source our products from a wide range of cargo producers and suppliers. We continue to be strict and vigilant with our testing programme for our products before delivering them to our customers. Equatorial has deepened our engagement with the wider industry to have a better and up-to-date understanding of the existing and new marine fuels.

MT: Can you share the evolution of commercial marine fuel procurement, blending and trading strategies on the back of increasing fuel types (pre/post IMO 2020)?

Pre IMO 2020, the main types of marine fuel procured and consumed by vessels were high-sulphur fuel oil, marine diesel oil and marine gas oil. Trading strategies were therefore closely linked to that within the oil industry.

However, many of the new fuel types are from other industries. For example, biofuels, methanol and ammonia are mainly products from the chemical and agriculture industries. There are marked differences between these industries and the energy industry (in particular, the marine fuels industry). LNG is from the gas industry which is distinct from the oil industry.

Without an existing liquid paper market for many of these commodities (especially as a marine fuel), the price risk management is less straightforward. Furthermore, commodity prices are no longer the sole consideration for price itself. The price of compliance must be considered. This could range from guaranteeing the origin of the marine fuel, its sulphur properties as well as its carbon intensity. The list goes on.

MT: Operational wise, what are the changing role and responsibilities of a bunker supplier to date, compared to before IMO 2020?

The role and responsibility of a bunker supplier have evolved. Fundamentally, it has been about providing quality marine fuels at competitive prices. Quantity assurance has been a critical concern which led to the mandatory implementation of the mass flow meter system for bunkering in the Port of Singapore. Interestingly, due to the nature of credit terms in the bunker industry, bunker suppliers also performed the role of “bankers” by extending favourable credit terms to shipowners and charterers.

These days, post IMO 2020, things have become even more complicated. Today, a bunker supplier retains the abovementioned roles and responsibilities, and much more – it has to ensure compliance with a plethora of rules and regulations. Compliance not only with sulphur cap requirements, but with international and regional sanctions and restrictions unrelated to the quality of the marine fuel itself. In fact, especially with alternative low- and zero-carbon marine fuels, this means compliance with standards, rules and regulations on sustainability such as the European Renewable Energy Directive and/or International Sustainability and Carbon Certification. There is also the need to comply with increasingly stringent safety regulations on both conventional and alternative marine fuels.

In addition to the above, a post IMO 2020 bunker supplier is still expected to supply compliant and quality fuel at competitive prices.

MT: Equatorial is Singapore’s largest local-born supplier; what is the next big thing for the company?

Equatorial continues to adapt and improve with the times, while maintaining its core values – Integrity, Teamwork, Commitment, Proficiency and Quality, and Safety and Environment. The bunker industry is a highly competitive one, and it is our intention to keep our competitive edge and remain relevant. This means that we have had to step out of our comfort zone and embrace the two mega trends of our time – digitalisation and decarbonisation.

We have been early adopters and developers of the electronic bunkering note as part of our own digital bunkering efforts. We have diversified our product offering to include low carbon marine fuels and are proud to be one of the pioneers for bunkering B100 biofuels earlier this year. This was made possible by the arrival of our IMO Type II chemical and oil bunker tankers. These same bunker tankers are also capable for carrying and delivering methanol. Equatorial has invested in an LNG bunkering vessel (LBV) newbuilding that is set to be delivered in Q3 2027. We are also involved in a study to develop low- or zero-carbon ammonia bunkering in Singapore.

These are exciting times.
