Research from FuelTrust, showed different batches of the same grade of marine fuel (such as VLSFO or HFO) having radically different degrees of energy intensity.

As such, knowledgeable fuel buyers have an opportunity to pick up 3% BTU of extra energy by bunkering with a different batch of fuel - saving ship owners thousands of dollars in fuel costs.

The analysis of different fuel batches was carried out using FuelTrust’s AI-powered Digital Chemist, which simulates combustion on a molecular level to identify differences in fuel properties such as fuel quality, energy, and emissions profiles. Digital Chemist combines the known characteristics of a fuel batch, with class data on the vessel engine, and data from the day logs to accurately establish what happens when fuel is burned.

Based on analysis of 14m barrels of VLSFO fuel across 28 batches, FuelTrust found that different batches of fuels could essentially provide higher energy, without the supplier or buyer realising for a fully laden Panamax container ship, this would equate to a 50MT saving of fuel on a voyage from Vancouver, Canada to Portsmouth, UK, or the equivalent of up to 469 nautical miles of additional sailing distance on a typical bunker.

“This isn’t like saying there’s a difference between gas stations – it’s more like there being a huge difference in the fuel you could buy at different pumps,” explained Jonathan Arneault, CEO of FuelTrust.

The energy intensity delta could be operationally challenging as regulations on fuels tighten, and particularly if, as expected, zero carbon fuels such as methanol become widely used. Because zero-carbon fuels are less energy-dense than currently used fuels, vessels will need to carry more fuel to continue to operate in the same way.

“Energy intensity matters. We’re about to see fuels come through with much a lower energy density than we’re used to,” continued Arneault.

Dr. Ram Vis, founder and director at the Viswa Group and advisor to FuelTrust, emphasised how energy density will become a major concern for fuel purchasers;

“If, as expected, you need twice the amount of methanol to do the same work as a tonne of HFO, buyers are going to have to pay a lot more attention to the BTUs that they are buying, as they’ll have to squeeze every drop of energy out of their fuel.”

“If we see the same batch-to-batch variation in zero carbon fuels as we do today with conventional fuels, that will be a real issue. Fuel buyers will need to start thinking more in terms of energy, and less in terms of volume”.

FuelTrust’s research indicates that differences in energy intensity will be matched by differences in emissions. With the proposed introduction of carbon taxes and emissions trading schemes, this could add up to thousands of dollars in taxes saved or lost, purely based on which batch of a fuel ends up in a vessel.

Launched in September this year, FuelTrust’s Bunker Insights platform uses a combination of artificial intelligence and blockchain technologies to establish an unalterable record of fuel transactions and to analyse and identify chemical risks and changes in fuel.

In doing so, Bunker Insights makes it simple for ship owners and charterers to monitor and manage fuel risk, allowing the industry to adopt more sustainable practices backed by meaningful insights into the fuel lifecycle.

Integr8 Fuels, the bunker trading and brokerage arm of Navig8, on Tuesday (7 November) released its Bunker Quality Trends Report Q3 2023, analysing data from 120 million metric tons of supply, to reveal key trends relating to fuel quality and availability. An excerpt of the report is as follows:

Introduction: Challenges fueling change

As we come to the end of another year in the world of bunkers that seems to have passed with the blink of an eye, our minds shift towards the challenges on the horizon and how as an industry we need to embrace change to profit and succeed in the future.

This is the third Integr8 Fuels quality report covering the last six months of supplies globally where we again dissect and compare the likelihood of hidden losses and off specification issues across all commercial grades of bunkers and key ports.

Using ‘best in class’ available data from over 120 million metric tons (MT) of deliveries globally across 1,300 locations and from over 800 suppliers, we will also assess fuel quality trends using our own Integr8 Quality Index which scores the proximity (or otherwise) of individual parameters within each sample to the relevant table 1 or table 2 specification limits within ISO 8217.

Finally, given the context of the incoming changes we will consider some of the challenges that decarbonisation and verification of emissions will bring to the industry.

Part 1: Off specification frequencies

How likely are we to be faced with an off specification situation?

In the last 180 days, owners’ analysis available to Integr8 Fuels has highlighted that you are equally likely to have an off specification issue with marine gas oil (MGO) as with high sulphur fuel oil (HSFO) with very low sulphur fuel oil (VLSFO) being one third less likely (see figure 1).

What is the likelihood of receiving noncompliant or critically off spec bunkers?

It is always important to consider the context of the off specification incidents.

To do this it is essential to consider the likelihood of MARPOL Annex VI (sulphur) or SOLAS (flash point) infractions and the likelihood of critical off specification incidents such as cat fines, total sediment potential, used lubricating oils, sodium and ash content (high risk) against routine and easily rectifiable off specification issues classified “low risk” such as a high viscosity in HSFO.

The rule of thumb when comparing off specification incidents by grade is that the parameters targeted in any blending model are the most likely to be outside the specification.

For example, VLSFOs are targeted on sulphur, with the price difference for 50,000MT of fuel with a sulphur content of 0.49 compared to 0.45 possibly equating to hundreds of thousands of dollars. It’s hardly surprising, therefore, that both VLSFO and MGO, both of which are blended to a sulphur target, have more prevalence of MARPOL Annex VI non-compliances at 0.5% and 0.1% respectively.

However, MARPOL Annex VI is not the only compliance issue - we cannot ignore the requirement for flash point being 60°C or above as demanded by SOLAS. Indeed, off specification flash point, particularly with LSMGO, may be an unintended consequence of pulling low sulphur automotive or inland grades into the bunker pool as identified later in this paper.

High risk off specification incidents, defined as the total of both compliance and high risk off specifications, are seen to be most prevalent in MGO followed by VLSFO and, finally, HSFO. In fact, if you strip out compliance off specification, incidents relating to total sediment potential (TSP), aluminium and silicon (Al+Si) etc. for residual grades are very low indeed.

That said, there are many nuances, from region to region, to port-to-port, and even supplier-to-supplier at the same location. It therefore remains essential to consider these when buying bunkers and we will address some of the challenges later in the paper.

Availability of products (September 2023)

Unsurprisingly, marine gas oil is the most available product (640 ports) given the ability to substitute and supply higher quality inland or automotive grades and logistical ease of supplying what are quite often small quantities.

VLSFO is also seen to be readily available across all continents but at 28% fewer ports (458

ports), this because of larger quantities being ordered and the storage and barge infrastructure to support these supplies in general.

High sulphur fuel oil is the only product which is not readily available, with only 231 ports listed as of September 2023 (see figure 2). HSFO availability is centered around bunkering hubs and geographically key areas likely to receive passing trade from VLCCs and / or other scrubber fitted sectors. It is important, therefore, to plan carefully for HSFO and consider the type of scrubber fitted to the vessel along with any local limitations in forthcoming voyages that may require a fuel switch to LSMGO, for example.

Biofuel blends

Data is now becoming available for tests of identified biofuels supplied globally and whilst this is still very small in comparison with conventional fuels, it is clear to see the apparent void stretching from Singapore to Europe currently present.

Moreover, we are not currently able to comment on the sustainability of the biofuels being supplied but can confidently predict that Indonesia fuels, for example, will likely be sourced from palm oil and would not satisfy a verifier of emissions. ARA, and in particular Rotterdam, is seen to be the epicenter of supply in Europe given the current subsidies available in the Netherlands. VLSFO blends are almost exclusively limited to bunker hubs.

Which specifications are being traded?

Even as we eagerly anticipate the new version of ISO 8217 hopefully expected in early 2024, we continue to work in the past when it comes to the specifications we buy and sell on a day-to-day basis.

The scale of the challenge can be laid bare by considering the charts below, (figures 4 and 5), which identify the split of residual and distillate ISO 8217 grades traded by product group in the last 180 days.

Residual Fuels

Just over one quarter of trades are guaranteed to the latest version of the specification (2017) which is virtually unchanged compared to previous figures.

Distillate Fuels

In the case of MGO, only 18% of fuels traded were sold as 2017 fuels in the last 180 days, slightly less than previous. A very slight reduction in 2005 fuels was noted from 11% to 9%, however it is worth remembering that this specification is nearly 19 years old.

Beijing-based commodity market information provider JLC Network Technology Co. recently shared its JLC China Bunker monthly report for October 2023 with Manifold Times through an exclusive arrangement:

Bunker Fuel Demand

China’s bonded bunker fuel sales decrease in October

China’s bonded bunker fuel sales decreased further in October, because of tighter supply.

The country tallied roughly 1.63 million mt of bonded bunker fuel sales in the month, with the daily sales down by 5.74% from September to 52,419 mt, JLC’s data shows.

The sales by Chimbusco, Sinopec Zhoushan and SinoBunker slid to 520,000 mt, 580,000 mt and 70,000 mt in the month respectively, while those by China ChangJiang Bunker (Sinopec) stabilized at 35,000 mt. At the same time, enterprises with regional bunkering licenses sold about 420,000 mt of bonded bunker fuel, up from 388,300 mt in September.

China’s bonded bunker fuel sales continued to drop, as low-sulfur fuel oil supply tightened and prices stayed relatively high. Meanwhile, the barging capacity at certain ports was affected by bad weather, which also depressed the sales.

China’s bonded bunker fuel exports inch down in Jan-Sept

China’s bonded bunker fuel exports edged down in the first nine months of this year, mainly because of a decline in domestic low-sulfur fuel oil (LSFO) output.

The country exported about a total of 15.24 million mt of bonded bunker fuel in January-September, a dip of 0.66% from the same months in 2022, JLC estimated, with reference to data from the General Administration of Customs of PRC (GACC).

Among the exports were 14.44 million mt of heavy bunker fuel and 802,600 mt of light bunker fuel, which accounted for 94.73% and 5.27% of the total, respectively.

Regarding the exports by supplier, enterprises with national bunkering licenses exported about 12.15 million mt of bonded bunker fuel in the nine months, accounting for 79.69%, while those with regional bunkering licenses supplied about 3.10 million mt, accounting for 20.31%.

Chinese refiners reduced their bonded bunker fuel exports in the first three quarters of this year, as domestic supply decreased amid falling LSFO production. Refineries lowered their LSFO output in the period when their production enthusiasm was greatly depressed by less considerable margins. The country produced about 11.10 million mt of LSFO in January-September, a cut of 5.45% year on year, JLC’s data shows.

In September alone, China’s bonded bunker fuel exports settled at 1.58 million mt, down by 2.79% from the previous month and 21.13% from a year earlier. Heavy bunker fuel exports amounted to 1.47 million mt, accounting for 92.73% of the total, while light bunker fuel exports stood at 115,200 mt, occupying 7.27%.

Suppliers with national bunkering licenses tallied approximately 1.18 million mt in the month, accounting for 74.23% of the country’s total, with Sinopec Fuel Oil and Chimbusco taking 64.35%. At the same time, enterprises with regional licenses exported about 408,300 mt, accounting for 25.77%.

JLC China Bunker Market Monthly Report (October 2023)

Domestic-trade bunker fuel demand extends gains in October

Domestic-trade bunker fuel demand extended gains in October, because of post-holiday restocking.

Domestic-trade heavy bunker fuel demand settled at 400,000 mt in the month, rising by 40,000 mt or 12.12% month on month, JLC’s data shows. Some shipowners increased purchases after the holiday for the National Day, as they had run out of stockpiles. Meanwhile, high-sulfur fuel oil prices fell to a relatively low level, which also attracted buyers to make deals.

Domestic-trade light bunker fuel demand surged to 165,000 mt in October, growing by 25,000 mt or 19.23% from a month earlier, the data indicates. Downstream buyers showed higher buying interest when MGO prices rolled back. At the same time, shipping demand at inland ports increased, with coal transportation speeding up amid the heating season in North China.

Bunker Fuel Supply

China boosts its September bonded bunker fuel imports

China boosted its bonded bunker fuel imports month on month in September, as domestic low-sulfur fuel oil (LSFO) output decreased rapidly.

The country tallied about 389,800 mt of bonded bunker fuel imports in the month, surging by 27.18% month on month, JLC estimated, with reference to data from the General Administration of Customs of PRC (GACC).

Domestic refineries slowed down their LSFO production amid bad margins, leading refiners to import more bonded low-sulfur bunker fuel to meet demand. The country produced about 1.17 million mt of LSFO in the month, with the daily output dropping by 5.40% month on month to 39,000 mt, JLC’s data indicates. Meanwhile, some distributors expanded their bonded low-sulfur bunker fuel imports as more unit maintenance and export quota tightness triggered fears of a further decline in LSFO output in the fourth quarter.

Imports of high-sulfur bunker fuel and marine gas oil (MGO) largely stabilized at a normal level.

Russia surpassed Malaysia and became the largest supplier by shipping 214,000 mt of bonded bunker fuel to China, accounting for 54.9% of China’s total imports. Malaysia slipped to the second place with 61,800 mt, accounting for 15.9%, while Singapore ranked third with 60,900 mt, occupying 15.6%. Shipments from South Korea were reduced to only 53,100 mt, accounting for 13.6% and bringing the country to the fourth place.

On a year-on-year comparison, however, China’s bonded bunker fuel imports fell by 8.90%.

China’s bonded bunker fuel imports totaled 2.88 million mt in the first nine months of this year, plunging by 19.18% from the corresponding months in 2022, decelerating from a 20.58% slump in January-August.

Domestic-trade bunker fuel supply continues to grow in October

Domestic-trade bunker fuel supply continued to grow in October, as blenders boosted production when their blending margins for bunker fuel were widened by a drop in blendstock prices.

Chinese blenders supplied about 450,000 mt of domestic-trade heavy bunker fuel in the month, a boost of 60,000 mt or 16.22% month on month, JLC’s data indicates.

Similarly, refineries ramped up their light bunker fuel production amid relatively fair margins. Domestic-trade marine gas oil (MGO) supply rose to 180,000 mt in October, an uplift of 20,000 mt or 11.76% from September.

Latest figures from DNV’s Alternative Fuels Insight (AFI) platform in October saw six LNG-powered vessels added to the database. Additionally, the trend of increased orders for methanol-powered vessels continues, with 14 methanol-fuelled vessels ordered.

October also saw the first confirmed order for two ocean-going vessels equipped with ammonia dual fuel systems.

Following in the footsteps of the first orders that were made for LNG, methanol, and LPG powered vessels, the initial orders for ammonia-fuelled vessels are for ships designed to also transport the same fuel as cargo.

“Finally, we have order confirmation on the first ocean going vessels with ammonia propulsion. This simplifies the chicken and egg dilemma related to fuel availability versus demand,” exclaimed Martin Wold, Principal Consultant in DNV's Maritime Advisory business.

“It also addresses crew training, as crew will already be trained specifically on gas and ammonia carriers, so this does not become an extra burden or risk to manage.

“Furthermore, we see that the drivers for alternative fuels in general, and the push for ammonia as a fuel in particular, compared to what was the case in the early days for LNG and methanol respectively, are much stronger at this stage of the industry development.

“So, we will see orders for other ship types even before we get operational experience from gas carriers using ammonia as a fuel.”
