ClassNK has independently verified residual marine fuels treated with Octamar™ combustion catalysts can achieve an average fuel economy improvement of 2.7% and a 60% reduction in Particulate Matter emissions including black smoke, carbon and other harmful substances.

It validated Innospec's additives were tested during field trials, on test bed engines and onboard various types of vessels, and exposed to in-lab tests such as the FIA test verified by a third party.

The verification document also substantiated Innospec contributing to CIMAC whitepaper No.69 that evaluates the effectiveness of additives under the Octamar™ Combustion Catalyst Series on combustion quality of fuel through a series of eight field trials.

Under the series, results between 2.1 to 3.0% fuel economy were achieved in three tests using pure combustion catalysts; fuel economy effects from 2.3 to 3.9% were recorded in four tests while using combinations of combustion catalysts with detergent/stabilizers; and pure organic combustion improvers achieved 3.7% improvement in fuel economy in one test.

“For Octamar™ F35C, the combination of combustion catalyst and combustion improver provides a faster and more complete combustion which will reduce unburnt fuel in exhaust, soot, PAH, post combustion fouling, black smoke, black carbon,” affirms Nicea Ng, Marine Technical Specialist, Innospec Limited.

“For Octamar™ Ultra HF and Complete, the combination of combustion catalyst, combustion improver and stabilizer/dispersant create a threefold effect on combustion catalysis, ignition improvement, homogenization and better atomization/spray pattern thus significantly reducing unburnt fuel in exhaust, soot, PAH, post combustion fouling, black smoke, black carbon.”

Giorgio de Leonardis, Vice President EMEA, Innospec Fuel Specialties meanwhile highlights Innospec has also became the first fuel chemistry supplier to be awarded the “Innovation Endorsement” from ClassNK.

“This endorsement demonstrates the unique value of Innospec products which have helped vessel owners and operators to enhance their fleet performance,” shares Leonardis.

“Today, as various solutions are being explored to meet environmental goals like CII, the Octamar™ range also provides a launching platform for current and future emission reduction strategies.

“Any improvement in fuel consumption will result in improvements in CO2 emissions.”

The recent oil leak incident at Police Coast Guard (PCG) Brani Regional Base has prompted checks on all fuel pipes at PCG’s three other bases for leaks, according to The Straits Times on Monday (10 February). 

Responding to queries from the local news provider, the police said all fuel pipes at Brani Regional Base were inspected on 6 February while fuel pipes at the other three bases at Loyang, Lim Chu Kang and Gul are also being checked with inspections expected to be wrapped up on 10 February. 

The police also said that a preliminary assessment on the cause of the leak might be due to micro cracks in a damaged fuel pipe as a result of repeated twisting of the pipe due to the movement of the pontoons caused by tidal changes.

On 6 February, Singapore authorities confirmed that a diesel oil leak was discovered at the Brani Regional Base on 5 February, at around 11.40am (Singapore Time). 

According to a joint statement by Singapore Police Force, Maritime and Port Authority (MPA) and National Environment Agency (NEA), about 23 metric tonnes had leaked from a damaged shore fuel hose used to refuel patrol craft at Selat Sengkir. 

The leak was eventually isolated at about 3.40pm and there were no oil slicks observed.

NYK conducts first Japan bio bunker fuel trial on coal carrier for domestic power utility firm

NYK conducts first Japan bio bunker fuel trial on coal carrier for domestic power utility firm

Japanese shipping firm NYK on Monday (10 February) said it has started a biofuel test run on its coal carrier Noshiro Maru, which is operated by Tohoku Electric Power on 9 February.

This is the first time in Japan that a coal carrier has been used to test biofuel for a domestic power utility company. Mitsubishi Corporation Energy in the Keihin area facilitated the supply of biofuel for the vessel.

Biofuels are made from organic resources (biomass) of biological origin, such as agricultural residues and waste cooking oil, and are considered to produce virtually zero carbon dioxide (CO₂) emissions when combusted.

“Since they can be used in heavy-oil-powered ship engines, which are common on large merchant ships, biofuels are considered a key means of reducing greenhouse gas (GHG) emissions in the transition period from heavy oil to zero-emission fuels,” NYK said. 

“Using biofuel to reduce GHG emissions during sea navigation also contributes to reducing Scope 3 GHG emissions generated by transporting customers’ cargo.”

NYK added it will continue to focus on introducing biofuels and other next-generation fuels, and will contribute to reducing GHG emissions in our customers' supply chains while promoting decarbonisation in marine transport.

IBIA welcomes IMO move to draft guidance change on carriage of bio bunker fuels

IBIA welcomed agreement by IMO’s Sub Committee on PPR 12 to draft Interim Guidance on the carriage of blends of biofuels and MARPOL Annex I cargoes by conventional bunker ships.

The International Bunker Industry Association (IBIA) on Monday (10 February) said it submitted a document to IMO on the carriage of biofuels for supply to a ship for use as fuel oil on board that ship in November 2023.

This highlighted that as conventional bunker vessels were limited in carrying fuel oil of no more than 25% biofuel it presented a potential impediment to the global adoption of biofuels as fuel oil for ships and so to the ambition for the decarbonization of international shipping in the short term, as set out in the 2023 IMO GHG Strategy.

“IBIA therefore welcomes the agreement by IMO’s Sub Committee on Pollution Prevention and Response (PPR 12) to draft Interim Guidance on the carriage of blends of biofuels and MARPOL Annex I cargoes by conventional bunker ships,” it said on its website. 

The guidance allows conventional bunker ships certified for carriage of oil fuels under MARPOL Annex I to transport blends of not more than 30% by volume of biofuel, as long as all residues or tank washings are discharged ashore, unless the oil discharge monitoring equipment (ODME) is approved for the biofuel blend(s) being shipped. 

“The Interim Guidance is expected to be approved by IMO’s Marine Environment Protection Committee (MEPC 83) in April,” IBIA added. 

“IBIA’s membership represents stakeholders from across the global marine fuel value chain, and being able to draw on this technically strong and credible resource will, in its role of having consultative status to the IMO, mean that IBIA will continue to bring important matters to the attention of the wider IMO membership for due consideration.”
