Why are there no Cold Flow Improvers CFI for VLSFO

Colorado-based global specialty chemicals company Innospec Fuel Specialties in December published a technical bulletin entitled Cold Flow – A Point on Pour Point. The document has been shared with Singapore bunkering publication Manifold Times:

Why are there no Cold Flow Improvers (CFI) for VLSFO?

Cold Flow Improvers (CFI) are created to target the most common N-Paraffins within a fuel. For MGO, this is relatively simple due to consistency in production and therefore in the n-paraffin distribution.

VLSFO quality is far more variable. Our research into n-paraffin distribution of VLSFO has shown that they not only differ from MGO, but significantly differ from each other. This means a cold flow improver designed for MGO will most likely not work on VLSFO, whilst CFI products designed for one VLSFO may not be effective in others.

CFL MGO vs VLSFO n paraffin distribution

The graph above gives an example of two VLSFOs with completely different n-paraffin profiles. CFI products are designed to target a specific range as illustrated by the treat range. We can see CFIs for the typical MGO will have limited to no impact on VLSFO 1 or VLSFO 2 as most n-paraffins for these fuels exist outside of the treat range.

Solution?

It would be possible to produce a specialist CFI to treat the n-paraffins of a single VLSFO, however the prospect of treating all VLSFOs with a single CFI is not practicable. In theory a single CFI could be designed to impact the entire n-paraffin range found in VLSFOs. However, such a treatment would require very high treat rates and prove prohibitively expensive and of little practical use.

The most practical way to prevent cold flow issues when using VLSFO is to ensure sufficient heating in fuel tanks, while maintaining temperatures in line with or close to the Wax appearance temperatures wherever practical.

Residual fuels are often highly viscous and require heating to bring their viscosity down to a level where effective pumping and injection is possible. For HSFO, fuels were stored unheated and then before use brought up to temperature.

However, VLSFO will require continuous heating in storage to prevent cold flow issues in colder climates. Though, much like heating MGO, heating lighter VLSFOs over time is not advised due to the onset of ageing which is common when lighter or FAME components are heated in the long term.

Note: The next Innospec Fuel Specialties technical bulletin to be released by Manifold Times next Wednesday (12 January) will cover the consequences of incorrect VLSFO heating with advice on how these issues may be overcome, together with tips on how to best manage paraffinic VLSFO and case studies.

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.

Technical considerations of ammonia as marine fuel

Muammer Akturk, ABS Regional Business Development Manager, on Monday (10 June) published an article on technical considerations of using ammonia as a marine fuel in his Alternative Marine Fuels Newsletter.

The article dives into the use of ammonia as a marine fuel, focusing on the safety and technical considerations necessary for its implementation.

Ammonia is recognised for its potential as a zero-carbon fuel, making it an attractive option for reducing greenhouse gas emissions in the shipping industry. However, it poses significant safety challenges due to its toxicity and flammability.

Key points discussed include:

  1. Safety Measures: The importance of stringent design and operational safety measures to prevent ammonia releases and mitigate risks during both normal and emergency conditions is emphasized. This includes the need for gas dispersion analyses and the use of safety systems like gas detectors and alarms
  2. Regulatory Framework: The article reviews the latest regulations and guidelines developed to ensure the safe use of ammonia as a marine fuel. This includes the IACS Unified Requirement H1, which provides a framework for controlling ammonia releases on vessels
  3. Engineering Considerations: Technical aspects such as fuel storage, handling systems, and the role of risk assessments in identifying potential hazards and implementing preventive measures are detailed
  4. Human Factors: The article also considers the human factors approach to safety, emphasizing training and the importance of designing systems that account for human errorOverall, the article aims to provide a comprehensive overview of the challenges and solutions associated with using ammonia as a marine fuel, highlighting the importance of safety and regulatory compliance in its adoption.

JLC Bonded bunker fuel sales in Zhoushan (Mar 2024)

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

Bunker Fuel Demand

China’s bonded bunker fuel sales surge in March

China’s bonded bunker fuel sales grew in March, as the shipping industry recovered gradually and sellers actively boosted sales on the back of ample supply and high inventories. Domestic LSFO prices were lower than those in Singapore and other neighboring ports, incentivizing shipowners or operators to refuel their vessels in China, with bunkering volume in Shanghai and Zhoushan rising considerably.

The country sold about 1.82 million mt of bonded bunker fuel in the month, with the daily sales up 13.59% month on month to 58,658 mt, JLC’s data shows.

Sales by Chimbusco, Sinopec (Zhoushan) and China ChangJiang Bunker (Sinopec) came in at 540,000 mt, 630,000 mt and 30,000 mt in March, while those by suppliers with regional bunkering licenses settled at 558,400 mt. At the same time, SinoBunker sold about 60,000 mt of bonded bunker fuel, the data indicates.

China’s bonded bunker fuel exports rise in first two months

China’s bonded bunker fuel exports rose in the first two months of this year, underpinned by fresh quotas and larger production.

The country exported a combination of 3.02 million mt of bonded bunker fuel in January-February, growing by 3.13% from the same months in 2023, JLC estimated, with reference to data from the General Administration of Customs of the PRC (GACC).

Heavy bunker fuel exports totaled about 2.85 million mt in the two months, accounting for 94.13% of the total, while light bunker fuel exports were 177,500 mt, accounting for 5.87%.

The increase in the exports mainly came as China released this year’s first batch of quotas on LSFO exports at the end of 2023. Though refiners’ LSFO production margins were relatively poor, they ramped up their production amid new quotas, which buoyed the exports. China’s LSFO output totaled 2.57 million mt in January-February, with the daily output gaining 2.69% year on year to 42,850 mt, JLC’s data shows.

In January alone, China’s bonded bunker fuel exports settled at 1.78 million mt, jumping by 11.93% month on month and 34.71% year on year.

However, the exports plunged to 1.25 million mt in February, down by 29.99% month on month and 22.75% year on year. Bunkering business at Chinese ports was halted during the Chinese New Year holiday, and customs’ clearing procedure for export was also affected by the holiday. In addition, the operation of many ports was hit hard by heavy snow and freezing rains, adding to the downward pressure on the exports.

Domestic-trade bunker fuel demand rises in March

Domestic-trade heavy bunker fuel demand recovered mildly in March, as the shipping industry rebounded after the Chinese New Year holiday. However, the demand growth was still limited as some shipowners still suspended services and the market was dominated by wait-and-see sentiment amid high prices.

Domestic-trade heavy bunker fuel demand was estimated at 430,000 mt in the month, a gain of 70,000 mt or 19.44% from a month earlier, JLC’s data shows.

Meanwhile, domestic-trade light bunker fuel demand was estimated at about 140,000 mt, a gain of 20,000 mt or 16.67% from a month earlier, the data indicates.

Bunker Fuel Supply

China’s bonded bunker fuel imports soar in Jan-Feb

China’s bonded bunker fuel imports soared in January-February 2024, due to a low base a year earlier.

The country recorded 581,900 mt of bonded bunker fuel imports in the two months, a surge of 27.36% year on year, with 359,200 mt in January and 222,700 mt in February, JLC estimated, with reference to data from the GACC.

China’s bonded bunker fuel imports dived to a record low in January-February 2023, as bunkering demand had not fully recovered from the epidemic, also because of high freight rates and ample domestic supply. The imports totaled only 456,900 mt in the first two months of 2023, tumbling by 48.01% year on year.

On the other hand, Chinese refiners boosted LSFO production in January-February 2024, limiting the import growth. These refiners produced about 2.57 million mt of LSFO in the two months, with the daily output climbing by 2.69% year on year to 42,850 mt, JLC’s data shows.

Russia became the largest bonded bunker fuel supplier in the first two months of this year, exporting 276,800 mt to China, accounting for 47.57% of the latter’s total imports. Malaysia ranked second with 186,800 mt, accounting for 32.10%, followed by South Korea with 95,800 mt, accounting for 16.46%. Japan climbed to the fourth place with 21,500 mt, occupying 3.69%, while Singapore slipped to the fifth place with only 1,000 mt, making up 0.17%.

In China’s bonded bunker fuel market, only HSFO and MGO are still mainly imported, while LSFO is rarely imported as its import efficiency is relatively low amid steep freight rates.

Domestic-trade bunker fuel supply increases in March

Domestic-trade heavy bunker fuel supply improved in March, as availability of some blendstocks (such as low-sulfur residual oil and shale oil) increased.

Chinese blenders supplied about 460,000 mt of domestic-trade heavy bunker fuel in the month, a rise of 60,000 mt or 15% from February, JLC’s data shows.

Similarly, domestic-trade MGO supply rose to 160,000 mt in March, up 30,000 mt or 23.08% month on month, the data shows. Refineries’ enthusiasm for MGO production improved in March, as domestic MGO prices moved up along with domestic oil products.
