DNV: Multifaceted approach to managing decarbonization risks

In a recent Maritime Impact article, classifiction society DNV offered a look into Great Eastern Shipping’s approach to decarbonization including bio bunker fuel trials, collaborating for green hydrogen and ammonia infrastructure and energy-saving retrofits:

In a time of regulatory uncertainty and evolving fuel options, shipowners like Great Eastern Shipping are taking a pragmatic route to decarbonization by focusing on flexible fleet upgrades and operational efficiencies while supporting Indian ports and government construction of a low-GHG fuel infrastructure.

As the shipping industry responds to IMO’s decarbonization goals for 2050, along with the interim targets for 2030 and 2040, many questions remain unanswered, reflecting the complexity of the path ahead. “The major challenge is the regulatory uncertainty,” says Capt. Ankush Gupta, Chief Operating Officer of the Great Eastern Shipping Company Ltd. (G E Shipping), India’s largest private-sector shipping company. “We desperately need a clear, final ‘basket of measures’, specifically the global fuel standard.” 

Drop-in biofuels can reduce emissions immediately

As shipowners and operators plot a course towards net-zero, they must carefully weigh their options to manage the potential increase in emission- and fuel-related costs. Which new fuel will be available at scale, when, and what will be the price tag? How long will it take ports to build up an adequate global bunkering infrastructure for new fuels? How will all this change the competitive environment? 

But this uncertainty has not stopped G E Shipping from taking action. “We are actively pursuing immediate, viable solutions,” says Gupta. “We’ve been a pioneer in India by successfully completing trials of marine biofuel blends on our tankers. This was a landmark achievement, demonstrating that sustainable drop-in fuels can achieve instant, meaningful emissions reductions in our existing fleet without requiring massive capital investment in engine modifications.” G E Shipping is now using biofuels on selected voyages where supply logistics allow, Gupta adds. 

Collaborating for green hydrogen and ammonia infrastructure in Indian ports

Operating a fleet of roughly 40 tankers, bulk carriers, and gas carriers, with more to be added soon, the company is pursuing a cautious but steady fleet renewal strategy in line with India’s ambitious national maritime vision.  

“Our decarbonization efforts are in line with the Indian government’s Maritime Amrit Kaal Vision 2047 and the Harit Sagar initiatives,” says Gupta. “As the country’s leading private-sector shipping company, we feel a responsibility to champion this transition. We’re very open to collaborating with Indian ports and government bodies, providing operational insights to help them shape the necessary infrastructure for green shipping corridors, especially in line with the national vision for green hydrogen and ammonia.”

Energy-saving devices and operational measures buy time

DNV’s Maritime Advisory experts completed a decarbonization study for G E Shipping’s entire fleet a few years ago, resulting in CII ratings and a decarbonization plan that delivers actionable recommendations. This has enabled G E Shipping to commit its resources to the most effective and cost-efficient measures. “Our primary focus is on energy-saving devices, installed during dry dockings,” says Gupta. “We’ve invested heavily in propulsion efficiency, fitting pre-swirl devices and high-efficiency propellers to reduce energy losses. These technical retrofits, along with engine part-load optimization, high-performance hull coatings, and hull cleaning, deliver substantial fuel and CO2 reductions.”  

Proactive biofouling management and the use of combustion catalysts are supporting these measures, while advanced voyage optimization and smarter autopilot systems help the vessels select the most efficient itineraries, achieving additional, measurable savings. G E Shipping is also exploring just-in-time arrival, working with the Blue Visby Consortium. “For the long term, our R&D evaluates technologies like air lubrication systems, wind-assisted propulsion, and onboard carbon capture as critical components for meeting our ultimate decarbonization goals,” remarks Gupta. 

Nevertheless, the company is well aware that these are short-term fixes, he adds. “These operational measures buy us time, but they won’t meet the ambitious mid-term targets.”

BHP and GCMD trial multi-feedstock B100 bio bunker fuel on bulk carrier

BHP and the Global Centre for Maritime Decarbonisation (GCMD) on Wednesday (3 June) said they have blended biofuels from two distinct feedstocks—used cooking oil and waste animal fats —and introduced the lower-emissions marine fuel into a BHP-chartered bulk carrier as part of a pilot project.

The bio-blend in the BHP and GCMD pilot is being used on a BHP-chartered bulk carrier Berge Lyngor, owned and operated by Berge Bulk, transporting BHP iron ore from Western Australia to China. When run on bio-blend, the vessel has the potential to reduce well-to-wake greenhouse gas emissions by approximately 79 per cent per voyage compared to sailing on very low sulphur fuel oil (VLSFO).

The vessel bunkered in Singapore in early May with a B100 bio-blend comprising 50 percent tallow-derived biodiesel, sourced and supplied by HAMR Energy, and 50 per cent used cooking oil (UCOME) supplied by Mitsui & Co Energy Trading Singapore (METS).

Mitsui also blended the fuel and Dan-Bunkering coordinated and executed the bunkering operation, which was performed by Global Energy’s barge MT Maple.

The BHP and GCMD pilot will assess how biofuels from multiple feedstocks can be blended, handled, and introduced under real-world operating conditions using existing used cooking oil bunkering infrastructure.

At the same time, insights from this pilot will help identify solutions to challenges related to fuel quality, handling, traceability, and onboard vessel performance.

Biofuels for global shipping today rely heavily on used cooking oil – a feedstock whose availability is approaching its projected limits. Biofuel from waste animal fats presents a promising option to expand the supply of lower-emissions marine fuels.

The outcomes of the pilot are expected to shed light on the practical steps to integrate biofuel blends from different feedstocks into existing supply chains. The diversity of biofuels will provide shipowners and operators with greater flexibility to optimise fuel procurement based on cost, availability, and lifecycle emissions performance.

Biofuels derived from different feedstocks can exhibit varying properties that may impact operations, including potential corrosion from oxidation, fuel system clogging caused by wax formation, which this pilot aims to assess.

The pilot will trace and verify the biofuel blend’s integrity aimed at bolstering confidence in emissions reductions reporting. The pilot will also provide insights into how robust tracing can support future marine fuel supply chains where biofuels from multiple feedstocks with varying lifecycle greenhouse gas emissions footprints are blended together.

This project is co-funded by the Maritime and Port Authority of Singapore under the Maritime Innovation and Technology Fund (MINT).

NYK starts one-year B100 bio bunker fuel trial on car carrier

Japanese shipping firm NYK on Tuesday (2 June) said it has commenced a one-year long-term trial involving the continuous use of 100% biofuel (B100) on an NYK-operated car carrier. 

In this trial, NYK will operate a car carrier continuously on B100 for one year to evaluate the impact on engines, fuel supply systems, and operational practices. High-purity biofuels such as B100 are known to be susceptible to degradation from oxygen, light, and heat, raising concerns about the stability of such fuels during long-term use.

In this trial, the biofuel primarily comprises FAME (Fatty Acid Methyl Ester) derived from used cooking oil and similar feedstocks.

The initiative is designed to evaluate the fuel’s effects on the vessel’s equipment and verify operational safety under real-world conditions. 

Through this effort, NYK seeks to accumulate technical expertise that will support the broader use of high-purity biofuels and further accelerate efforts to reduce greenhouse gas (GHG) emissions.

NYK has been advancing the use of biofuels through various initiatives. In 2024, the company conducted a trial using biofuel blend B24 and subsequently expanded practical usage to B30. However, the company said there remains limited global experience with the long-term continuous use of B100.

“By collecting long-term operational data through this trial, NYK aims to accumulate valuable technical insights to support both the safe operation of vessels and the wider adoption of high-purity biofuels,” it said.
