VPS: Shipowners face ‘tricky situation’ to balance VLSFO shelf life and wax appearance temperature

‘Generally, you have to heat VLSFOs to prevent waxing, but the more you heat them the lower the shelf life is going to be,’ Dr Malcolm Cooper, the Group Managing Director of VPS, tells Manifold Times.

The following article is part of pre-event coverage for the upcoming Singapore International Bunkering Conference and Exhibition (SIBCON) 2020; where Manifold Times is an official media partner:

Shipowners using Very Low Sulphur Fuel Oils (VLSFOs) as bunker fuel to meet IMO 2020 requirements have entered into a “tricky situation” of finding the perfect temperature for fuel storage, says the Group Managing Director of international fuel testing and inspection firm Veritas Petroleum Services (VPS).

“Generally, you have to heat VLSFOs to prevent waxing, but the more you heat them the lower the shelf life is going to be,” Dr Malcolm Cooper told Singapore bunkering publication Manifold Times.

He shared some common situations that shipowners are now facing with VLSFOs and offered advice for stakeholders who have already measured the Wax Appearance Temperature (WAT), Wax Disappearance Temperature (WDT) and Total Sediment Potential (TSP) of their product:

VLSFOs with high TSP and high WAT

  • Characteristics – Heating of these fuels in the storage tank to keep the temperature above WAT to prevent cold flow issues can cause TSP to rise and increase stability issues. By the time the vessel starts to burn the fuel, the TSP could become off-spec and thick sludge is formed. Typically, the fuel forms sludge at the purifiers and increasing the temperature further (from storage to separation temperature) has generally worsened the situation.
  • Recommendation – Limitation of VLSFO bunker storage time on board to 3 months.

VLSFOs with low viscosity (<10) and high WAT (WAT>40°C and WDT>75°C)

  • Characteristics – The product’s separation temperatures may be lower than WAT and for that reason the vessel cannot at any time heat the fuel above WAT. This causes a problem with sludge formation in the storage tank and transfer pipeline, and results in filters clogging with wax, together with serious handling and transfer issues.
  • Recommendation – Controlled use of additives in some cases can improve the situation just enough to use the remaining fuel.

VLSFOs where WDT is above 75°C

  • Suggest carrying out an exact flashpoint test to make sure that the fuel is not being heated above the flashpoint.

However, the measurement of the WAT and WDT of VLSFOs have always been a challenge as the product, typically a blend of 80% heavy fuel oil (HFO) and 20% marine gas oil (MGO), is not transparent, according to Dr Cooper.

“Current test methods to measure cloud point can only be applied to petroleum products that are transparent in layers of 40mm in thickness. For this reason, the CIMAC recommendation is to keep the fuel at 10°C above the pour point,” he says.

Though the occurrence of extremely high WAT measurements has significantly decreased over 2020, attention needs to be given towards an ongoing development where VPS detected an increase in the number of VLSFOs with very low pour points over the past few months.

The development could also mean a shipowner receiving VLSFO with a very low pour point with a high WAT (for example >PP + 200C or more) and having his bunkers turn into wax/sludge if following the advisory of CIMAC to store marine fuel at 10°C above the pour point. This is because measurement of pour point is an unreliable indicator of WAT/cloud point.

“The VPS recommendation is to measure WAT to be absolutely sure of the cloud point and to proactively maintain the fuel condition for efficient storage and handling of the fuel,” suggests Dr Cooper.

A bespoke VPS method to measure WAT/Cloud Point of VLSFOs

Fortunately, VPS has already conducted a significant amount of research to develop a reliable method for the measurement of cloud point of VLSFOs during Q2/Q3 2019, shared Dr Cooper.

The output was a White Paper (available from the VPS website) outlining an automatic test method for WAT which is the cloud point of VLSFOs.

The method was validated by correlating with current methodology used for distillates, while its repeatability has been confirmed across the range of 10°C to 65°C.

“This bespoke VPS method allows the WAT/cloud point of VLSFOs to be measured. The method also enables the measurement of WDT which is the temperature at which the last wax solids are melted back into liquid when the oil is heated,” he notes.

“VPS has now measured the WAT/cloud point of thousands of VLSFO samples. As may be expected, we have seen a direct correlation between the WAT and the likelihood of operational issues arising from waxing/sludging of the fuel.”

Bonded bunker fuel sales in Zhoushan JLC Nov 2024

Beijing-based commodity market information provider JLC Network Technology Co. recently shared its JLC China Bunker monthly report for October 2024 with Manifold Times through an exclusive arrangement:

China’s bonded bunker fuel sales plunge in October

China’s bonded bunker fuel sales plunged in October, due to lingering tightness of LSFO supply and the bad weather at certain ports.

The country sold about 1.45 million mt of bonded bunker fuel in the month, which was the lowest level since February 2022, JLC’s data shows. The daily sales settled at 46,881 mt in October, tumbling by 15.28% month on month.

Bonded bunker fuel sales by Chimbusco, Sinopec (Zhoushan), SinoBunker and China Changjiang Bunker (Sinopec) stood at 410,000 mt, 530,000 mt, 40,000 mt and 25,000 mt in the month, while those by suppliers with regional bunkering licenses settled at 448,300 mt, the data indicates.

China’s bonded bunker exports surge in September, but sales decline

China’s bonded bunker fuel exports surged in September, because of brisker re-export trade, but its actual sales declined amid tighter domestic supply.

The country exported about 2.18 million mt of bonded bunker fuel in the month, with the daily exports at 72,790 mt, up by 45.60% month on month and 37.82% year on year, JLC estimated, with reference to data from the General Administration of Customs of PRC (GACC).

Specifically, heavy bunker fuel exports totalled 1.90 million mt, accounting for 87.19% of the country’s total, while light bunker fuel exports increased to 279,800 mt, accounting for 12.81%.

Though bonded bunker fuel exports jumped amid more re-export trade activities, the actual sales descended as domestic refiners cut their LSFO production and port operation in East China was dampened by typhoons.

Chinese refiners produced about 993,000 mt of LSFO in the month, with the daily output at 33,100 mt, a slump of 11.16% from August and 15.13% from a year earlier, JLC’s data shows.

China issued this year’s third batch of quotas on LSFO exports in September, which was also expected to be the last batch for 2024, permitting only 1.0 million mt of exports, bringing this year’s total quotas to 13 million mt, down from 13.17 million for 2023 (the country issued quotas on 14 million mt for 2023, but some quotas were later converted to clean oil products).

China’s bonded bunker fuel exports totalled 15.09 million mt in the first nine months of this year, with the daily exports at 55,078 mt, sliding by 1.36% from the same period of time in 2023. Heavy bunker fuel exports came in at 14.08 million mt in January-September, accounting for 93.28%, while light bunker fuel exports stood at 1.01 million mt, making up 6.72%.

Domestic-trade heavy bunker fuel demand shrinks in October

Domestic-trade heavy bunker fuel demand shrank in October, because of multiple factors.

Domestic-trade heavy bunker fuel demand settled at 360,000 mt in the month, a decline of 30,000 mt or 7.69% month on month, JLC’s data shows. Most shipowners reduced purchases in early October, as they preferred to consume stockpiles during the National Day holiday. Operating ships decreased in mid-to-late October amid strong typhoons in southern China, and some ports’ bunkering business was hindered by the bad weather.

Domestic-trade light bunker fuel demand came in at 130,000 mt in the month, a loss of 10,000 mt or 7.14% from the previous month. Trade in the light bunker fuel market was limited, with shipowners still hesitant to make deals.

Bunker Fuel Supply

China’s bonded bunker fuel imports hit 22-month high in September

China’s bonded bunker fuel imports jumped significantly and set a 22-month high in September 2024, as domestic LSFO supply declined amid tight quotas.

The country imported 566,700 mt of bonded bunker fuel in the month, skyrocketing by 60.63% from the previous month and 45.38% from a year earlier, JLC estimated, with reference to data from the GACC. The imports hit the highest level since November 2022.

Bonded distributors imported more LSFO to meet demand when domestic refiners slashed their production amid lingering quota tightness. However, these distributors cut their high-sulphur fuel oil imports as their inventories remained relatively high. The imports of MGO were basically stable in September.

Malaysia still topped all suppliers by exporting 202,500 mt of bonded bunker fuel to China, which accounted for 35.73% of China’s total imports. Brazil came in second with 138,300 mt, accounting for 24.40%, followed by Singapore with 99,800 mt, making up 17.61%. Iraq and South Korea slipped to the fourth and fifth place with 85,200 mt and 40,900 mt, occupying 15.03% and 7.22% respectively.

China imported roughly 3.36 million mt of bonded bunker fuel in the first nine months, an upsurge of 16.39% from the corresponding months in 2023, speeding up from a rise of 11.86% in January-August.

China’s bonded bunker fuel imports are expected to hit a 23-month high in October, as domestic supply tightens amid quota shortages.

Chinese bonded bunker suppliers have imported more LSFO to meet demand lately, as Chinese refiners have cut their production amid shortage of quotas, according to market sources. By the end of September, Chinese oil refiners with LSFO export quotas (Sinopec, PetroChina, CNOOC, Sinochem and Zhejiang Petroleum and Chemical) had used 87.4% of their 2024 quotas, leaving quotas on only about 1.63 million mt for the last quarter, JLC’s data shows. This means they are likely to produce an average of roughly 545,000 mt of LSFO a month in the last quarter, versus a monthly average of about 1.26 million mt in January-September.

Domestic-trade bunker fuel supply tightens in October

Domestic-trade bunker fuel supply tightened in October, as cargo delivery was impeded by strict tax inspection, though the availability of blendstock increased.

Chinese blenders supplied about 370,000 mt of heavy bunker fuel in the month, a cut of 30,000 mt or 7.50% month on month, JLC’s data shows. At the same time, domestic-trade MGO supply slipped to 160,000 mt, down by 10,000 mt or 5.88% from a month earlier.

Report: €40 billion needed for EU shipping’s energy transition

Building a supply chain for clean fuels in Europe is a priority for the industry to meet its decarbonisation targets and for Europe to achieve its climate targets, say stakeholders.

Clean Maritime Fuels Platform

Clean Maritime Fuels Platform on Thursday (7 November) called on policymakers to create the regulatory conditions to unlock investments in the production of clean maritime fuels in the EU.

The Draghi Report estimates that €40 billion in annual investments will be needed between 2031 and 2050 for the energy transition of shipping.

Building a supply chain for clean fuels in Europe is a priority for the industry to meet its decarbonisation targets and for Europe to achieve its climate targets.

Clean Maritime Fuels Platform supports the report’s conclusions regarding the need to:

  • De-risk investments in renewable and low carbon fuels, for example via schemes based on Contracts for Difference and auctions as a service.
  • Launch dedicated sectoral calls under the Innovation Fund for the first deployment of decarbonisation solutions. The 20 million EU ETS allowances allocated to the decarbonisation of the maritime sector until 2030 should be used as soon as possible.
  • Expand existing funding mechanisms for refuelling and recharging infrastructure.
  • Start building a supply chain for renewable and low-carbon fuels in the EU.

European manufacturing capacity should match demand for clean shipping fuels in Europe as much as possible, in line with the benchmark of the Net-Zero Industry Act.

“The Draghi Report has recognised the global leadership of European shipping and the need to remain internationally competitive. In order to meet our targets, we need clean fuels available in the market in sufficient quantities and at an affordable price. To ensure that the shipping energy transition happen, the EU should de-risk investment in renewable and low carbon fuels and start building a supply chain for renewable and low-carbon fuels in the EU. Moreover, existing funding mechanisms for refuelling infrastructure should be expanded to better ensure the security of supply of clean fuels for shipping”, said Sotiris Raptis, ECSA Secretary General.

"Mr. Draghi’s report acknowledges the strategic role of renewable and low-carbon fuels, particularly in decarbonising all transport modes. His report highlights the EU's leadership in this area and calls for a truly technology-neutral approach. We, European Fuel Manufacturers, believe the right EU policy framework and subsidies can create a robust business case to attract private investments and avoid de-industrialization, help the EU successfully deliver climate neutrality by 2050, ensure a secure supply of energy, and foster innovative, EU-based, globally competitive industry for the welfare of EU economies and citizens", stated Liana Gouta, Director General of FuelsEurope.

“By linking the FuelEU Maritime with the supply mandates of the Renewable Energy Directive and abolishing stringent eligibility criteria, we can gradually increase eFuel capacities in the maritime sector.”, said Ralf Diemer, Managing Director of the eFuel Alliance.

“The following decade will lead to a fundamental shift in the European maritime fuel supply structure owing to the introduction of new regulations. The Draghi report places renewable and low-carbon fuels at the forefront of decarbonisation for the hard-to-abate maritime sector, and our industry is fully ready to support European shipowners to achieve this transition in a sustainable and cost-efficient way”, said Angel Alvarez Alberdi, Secretary General of EWABA.

“It is crucial to create a fertile environment for companies to invest in the production of competitive clean shipping fuels in Europe. Building on the Net-Zero Industry Act and the recommendations of the Draghi report, policymakers need to focus on to the importance of building a robust European supply chain for hydrogen and hydrogen derivatives in the maritime sector”, said Daniel Fraile, Chief Policy Officer of Hydrogen Europe.

“In the spirit of the Draghi-report, and for stimulating public and private investments, the EU should ensure that its regulations are in line with global developments, also in the maritime domain and notably with the IMO”, said R. Tim Eestermans, Managing Director Europe, Methanol Institute.

Sea Cargo Charter 2024 report

The shipping industry must take urgent action to meet ambitious new climate targets set by the International Maritime Organization (IMO), according to a new report released on Thursday (13 June) from the Sea Cargo Charter (SCC), a global transparency initiative developed by the Global Maritime Forum.

New data from the SCC, a global framework representing 20% of global bulk cargo transport, reveals the sector fell short of minimum international climate goals set by the IMO by an average of 17% in 2023, equivalent to 165 million metric tonnes of CO2e.

When considering ‘striving’ goals set by the IMO, signatories are on average 22% misaligned, which represents a shortfall of 204 million metric tonnes of CO2e in 2023.

Currently, dry bulk, general cargo, and tankers account for around 400 million tonnes of CO2 emissions. With global trade predicted to quadruple by 2050, emissions will skyrocket without urgent action.

Reporting has also been expanded to include “well-to-wake” emissions, which measure emissions from the extraction of oil to its end use, providing a more comprehensive picture of environmental impact and pushing the industry towards faster decarbonisation.

The 2024 report highlights the gap between current emissions and the IMO’s revised strategy for net-zero emissions by 2050. The report shows the importance of commercial and operational decisions on the vessels’ use (such as, instructed speed, cargo and routing optimisation, laden/ballast ratio), innovation and cooperation within the industry to be able to take action in this transition.

Other identified barriers to cutting emissions are geopolitical disruptions, limited alternative marine fuel options for long voyages, and a lack of infrastructure to support new technologies.

The 2024 Annual Disclosure Report was produced by the Global Maritime Forum, which performs secretariat services for the Sea Cargo Charter with expert support provided by UMAS and the Smart Freight Centre.
