The article below Managing Change – Oil Condition Monitoring & the 2020 Global Sulphur Cap is written by Paul Parkinson – VPS Global OCM Business Development Leader:

Driven by the International Maritime Organisation (IMO), the marine industry is currently going through important and significant environmental changes through a reduction in sulphur content of marine fuel from 3.5% to 0.5%. To fulfil this new requirement, stakeholders in the industry are debating and considering the merits of alternative fuels, different engine equipment and configurations as well as advances in scrubber cleaning technology. Fuels and lubricants both come into contact with engine systems so any changes that occur will have an even wider impact on marine vessel equipment. To minimise the impact of any negative consequences it is important to manage this change effectively.

Managing change effectively is an attitude supported in wider industry sense. Henry Mintzberg and John Kotter are change management experts and both say we must manage change and continuity simultaneously. Kotter says "What we do not do well is identify the most important hazards and opportunities early enough, formulate creative strategic initiatives nimbly enough, and implement them fast enough.”

One method to manage the effects of the Sulphur Cap is through monitoring of the in-service lubricant. Oil Condition Monitoring (OCM) utilises the science of tribology, and enables the condition of a vessel’s engines and other on-board equipment to be monitored. OCM provides an early warning system which when used in combination with fuel analytical information, helps to avoid costly engine failure and downtime and has an important role in preventive maintenance programs.

The best analogy is that of a blood test taken by your doctor to identify, predict and help combat on any potential health issues.

During the combustion cycle, Sulphur in the fuel is released forming SO2 (Sulphur Dioxide) and some of this forms SO3 (Sulphur Trioxide). Water contained within the scavenging air and from the combustion process reacts to form Sulphuric Acid. It is important, therefore, to monitor and control any negative and potentially damaging effects of acidity and alkalinity.
In built mechanisms in the form of oil additives are designed to improve the lubricant performance of the base oil. The choice of additives is determined by the specific application. For the 2020 change, alkalinity additives (like Calcium Carbonate) will be useful to combat oil acidity.

Why Alkalinity Additives? Most modern two stroke engines have been designed for operation on high sulphur residual fuel. Consequently, the cylinder oil used will have a high base number (BN). If the acid is not neutralised, corrosion of iron will occur and this is the primary cause of corrosive wear for liners and piston rings. Conversely a vessel using low and ultra-low sulphur fuel will produce less sulphuric acid during the combustion process. If the BN of your cylinder oil is too high this may mean that the oil is too alkaline and then compounds can be formed which may cause damage. Some slow speed engines suffer from alkaline deposits building up on the piston crown which can damage the oil film between the piston ring and liner. This can lead to scuffing and seizures. Deposits may also form between the piston rings and pistons, preventing free movement of piston rings and increased liner wear.

Why is OCM important then? Degradation of the oil occurs over time as these protective additives are consumed and engine breakdown products build up. It is important that these changes are monitored and acted on.

Total Base Number (TBN) in a marine oil generally ranges from approximately 15-80mgKOH/g and is analysed by Potentiometric Determination (Test method: ASTM D4739). This method, for used oil, uses a less polar solvent and weaker titrant than the fresh oil version. The sample is dissolved in a solvent mixture and then titrated with standardised hydrochloric acid. The end point (inflection point on a titration curve) is detected by a change in potential of an electrode connected to a voltmeter/potentiometer and is reported in milligrams of potassium hydroxide equivalent per gram of sample (mg of KOH/g).

Typically, the higher the BN, the more acid it will be able to neutralize. As the oil becomes contaminated with acids the base number will drop.

Expert independent advice is provided using CIMAC guidelines (from the International Council on Combustion Engines) as well as a simple summary using easy to read icons for Satisfactory, Caution and Action.

In conclusion, we remember Henry Mintzberg's and John Kotter’s approach that we must manage change and continuity simultaneously. Participating in an established lube oil testing program can help vessel operators to manage operational risk, comply with 2020 legislation and optimise costs during these changing times. For this to happen it is important that you partner with an experienced and informed supplier that can help monitor this change and provide impartial fuel and lubricant advice. Veritas Petroleum Services has an important role in OCM and Fuel Testing preventive maintenance programs. Our Rotterdam Laboratory has the very latest analytical technology, automation and robotics for the testing of lubricants and fuels.

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

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.
