Study: Engine efficiency will be as important as new bunker fuels in future cylinder oil performance

Higher pressures and temperatures used to achieve greater engine efficiency mean lubricants will need to be more resistant to these challenging in-cylinder environments.

Ship operators will need thermally resilient, low-ash formulations and high cleaning performance from cylinder oils as they begin to use more advanced engines and new bunker fuels, according to a new white paper published by Chevron Marine Lubricants on Thursday (23 June). 

The whitepaper The Future of Marine Two-Stroke Engine Lubrication features input from engine designers, MAN Energy Solutions and WinGD as well as the International Council on Combustion Engines, CIMAC. 

The result is a wide-ranging perspective funnelling into sharp insights on how emerging engine designs and the growing use of sustainable fuels will affect cylinder condition.

Pat McCloud, General Manager, Chevron Marine Lubricants, said: “Our mission is to help navigate uncertainty, delivering robust and reliable lubricant performance to keep engines operating cleanly whatever the fuel, whatever the design. This paper highlights the emerging needs that Chevron Marine Lubricants will have to fulfil to meet that mission.”

One finding in the paper is that, while fuels are dominating discussion in the maritime market, advancing engine efficiency will play an equally important role in defining marine cylinder oil performance demands. The higher pressures and temperatures used to achieve greater engine efficiency mean that lubricants will be needed that are more resistant to these challenging in-cylinder environments.

The increasing use of exhaust gas aftertreatment systems – as well as potential future engine designs to use new fuels - will accelerate demand for low-ash oils. Aftertreatments will increasingly be used to reduce air pollutants like sulphur and nitrogen oxides (and perhaps eventually capture carbon) in line with regulatory requirements. Post-combustion systems can be sensitive to ash deposits and new oil formulations will be needed to minimise this impact.

Luc Verbeeke, Senior Engineer, Chevron Marine Lubricants, said: “Advanced engine designs and emerging fuels place a new challenge on cylinder oils. However, the fundamentals of cylinder lubrication remain the same – to keep cylinders clean and moving freely for as long as possible. Chevron Marine Lubricants has always been at the forefront of cylinder oil technology, and we are already well-advanced in meeting the emerging needs outlined in this paper.”

Singapore: Bunker fuel sales down by 9.1% on year in January 2025

Sales of marine fuel at Singapore port decreased by 9.1% on year in January 2025, according to Maritime and Port Authority of Singapore (MPA) data.

In total, 4.46 million metric tonnes (mt) (exact 4,461,710 mt) of various marine fuel grades were delivered at the world’s largest bunkering port in January, a drop from 4.91 million mt (4,906,100 mt) recorded during the similar month in 2024.

Deliveries of marine fuel oil, low sulphur fuel oil, ultra low sulphur fuel oil, marine gas oil and marine diesel oil in January (against on year) recorded respectively 1.66 million mt (zero from 1.66 million mt), 2.43 million mt (-15% from 2.86 million mt), 900 (+100% from zero), 3,100 mt (-77% from 13,500 mt) and zero (from zero).

Bio-blended variants of marine fuel oil, low sulphur fuel oil, ultra low sulphur fuel oil, marine gas oil and marine diesel oil in January (against on year) recorded respectively 16,000 (+100% from zero), 92,000 mt (+103% from 45,300 mt), zero (from zero), zero (from zero) and zero (from zero).

LNG and methanol sales were posted respectively at 6,600 mt (-36.5% from 10,400) and zero (from zero).

Singapore-based Straits Bio-LNG aims to deliver 250,000 mt of bio-LNG bunker fuel per year

Straits Bio-LNG, a privately owned supplier of bio-LNG, is aiming to deliver 250,000 metric tonnes (mt) of bio-LNG per year in Singapore, according to SEA-LNG on Thursday (13 February).

The Singapore-based company, led by SK Tan as CEO, is doing so in response to the growing demand for LNG. LNG bunkering volumes have grown significantly in key bunkering hubs as more LNG-fuelled vessels have entered into operation. 

The Maritime and Port Authority of Singapore (MPA) saw a dramatic four-fold increase in 2024 to almost 340,000 mt, SEA-LNG said in a statement announcing Straits Bio-LNG joining the coalition. 

Headquartered in Singapore, the company boasts a growing team led by SK Tan as CEO.  

Yiyong He, Director at Straits Bio-LNG, said: “We’re firmly convinced in the viability of the LNG pathway to decarbonise the shipping industry. With its very low carbon intensity and improving commerciality, liquified biomethane will be a critical piece of the puzzle for decarbonising the sector.”

“By joining SEA-LNG, we’re proud to be part of a collection of first movers making real strides to make the LNG pathway a tangible reality today.”

Straits Bio-LNG aims to reach its bio-LNG supply goal by using pioneering methods. It is currently in the advanced stage of testing breaking down Empty Fruit Bunch (EFB) through an established biological process with high enzyme concentration in its R&D facility in Malaysia. 

Both Palm Oil Mill Effluent (POME) and EFB are sustainable biomass resources listed in the “List of Materials Eligible for ISCC EU Certification” and are therefore compliant with the European Union’s Renewable Energy Directive (RED).

Peter Keller, chairman of SEA-LNG, added: “The Port of Singapore is the largest global bunkering hub. As seen in our View from the Bridge report, 2024 saw record growth in LNG and liquified biomethane bunkering, but we need more fuel to meet upcoming demand.”

“The use of liquefied biomethane as a marine fuel can reduce GHG emissions by up to 80% compared to marine diesel on a full well-to-wake basis. When produced from the anaerobic digestion of waste materials, such as manure, POME or EFB, methane that would otherwise be released into the atmosphere is captured, resulting in negative emissions of up to -190% compared with diesel."

An independent study by the Maritime Energy and Sustainable Development Centre of Excellence at Nanyang Technical University in Singapore found that pure bio-LNG could cover up to 13% of the total energy demand for shipping fuels in 2050, rising to 63% for a 20% blending ratio. 

SEA-LNG added MPA has firmly established itself as a leader in the LNG pathway, with suppliers such as Straits Bio-LNG reinforcing this position. 

Recently, the port launched an Expression of Interest (EOI) to explore scalable solutions for sea-based LNG reloading to complement the existing onshore LNG bunkering storage and jetty capacities and the supply of e/bio-methane as marine fuel in the Port of Singapore.

“Straits Bio-LNG will play a critical role in furthering the expansion of liquified biomethane at scale to meet the demand and continuing to showcase the LNG pathway as a practical and realistic solution for shipowners to decarbonise their operations, starting today,” it said.
