Scott Oh, Director, Asia Operations at Wärtsilä Exhaust Treatment, recently shared with Singapore bunkering publication Manifold Times on their success in the current market for scrubbers and recent scrubber sales in Asia as well as elaborates on its CCS-Ready 35MW scrubber:

With the wide and relatively stable spread between high and low sulphur fuels, scrubbers continue to present a favourable economic proposition, and payback time has now reached less than two years for several vessel types.

These technologies’ role in Global Sulphur Cap compliance is well known. But, today, beyond solely tackling SOx, scrubbers have become a platform from which multiple technologies can work together in the stack and throughout the exhaust chain. This includes tackling NOx emissions by adding selective catalytic reduction systems (SCR) or exhaust gas recirculation systems (EGR) to ensure compliance with MARPOL Tier III requirements. In addition, scrubbers can reduce Particulate Matter (PM) 2.5 levels below even standard land-based requirements and a filter can be applied to capture microplastics.

Finally, and most importantly, scrubbers can now also be installed in a way that sees them primed and ready for onboard CO2 capture and storage (CCS), making them a futureproofed investment for achieving marine decarbonisation goals in a short timeframe. This has been particularly recognised in Asia and by Asian shipowners, because it is here where Wärtsilä received its first order for CCS-Ready scrubbers in November 2022. This landmark order includes systems for four 8,200 TEU container vessels which will be fitted with Wärtsilä’s CCS-Ready 35MW scrubber in an open loop configuration.

At its core, CCS-Ready means that Wärtsilä is conducting the requisite engineering and naval architecture at the outset to ensure adequate space for the future installation of a CCS system, as well as incorporating considerations for minimising idle load and optimising utilities, and preparing the control and automation system.

Owners are looking to future-proof their existing fleet and newbuildings while the regulatory environment is still evolving and at a time when yard space is in high demand. Concurrently, they are taking advantage of higher charter rates, particularly in the container ship market, so for retrofits, minimising off-hire time is critical. They need a partner that has the ability, relationships and experience to cooperate with yards and manage the process from sales to installation.

A first 2D layout drawing provides owners with an understanding of the scope of the installation and enables onboard space to be reserved. A full technical feasibility study can then be undertaken before or after contract signing. Owners typically make most decisions within the first four weeks after contract signing. This is when the equipment, piping and possible tanks are modelled, and owners may consider their preferences, such as tank locations, to ensure the design process is straightforward.

This phase also includes considerations on how best to futureproof the installation, leaving room for adaptation to CCS or hybrid functionality. The work required to allow for a CCS add-on is mainly done on the drawings at this stage, but some modifications can be made to the scrubber body. Space will need to be reserved above the scrubber and the funnel may need raising a few metres. In some cases, it makes sense to do this as early as possible.

Shipyard involvement is critical. Generally, shipyards should take the input of suppliers and ‘own’ the detailed designs themselves, ensuring a smooth and fast process that avoids confusion during installation. Co-operation between the basic and detailed designer remains important, and a good scrubber manufacturer will act as a link between all parties. In some cases, it is personal relationships and prudent communication skills more than the contract that can ensure positive, timely outcomes.

Wärtsilä has a strong presence in the Asian scrubber market after receiving Type Approval from the China Classification Society (CCS) in 2020. This was achieved when Dalian Shipbuilding Industry ordered a scrubber for the New Treasure, a newbuild VLCC. The vessel was built for Associated Maritime of Hong Kong, part of the China Merchants Energy Shipping (CMES) group, the largest VLCC owner in China.

Owners’ confidence in scrubbers as a technology platform for compliance with IMO goals and the wider decarbonisation picture has increased with advanced scrubber solutions, and by choosing the right partners, they can be confident they will overcome the engineering challenges and remain competitive.

CBL International Limited (CBL), the listing vehicle of Banle Group, a leading marine fuel logistic company in the Asia-Pacific region, on Thursday (17 April) announced its annual financial results for the year ended 31 December 2024.

The company reported a consolidated revenue of USD 592.52 million for the year, marking a 35.9% increase from USD 435.90 million in 2023.

This growth was primarily driven by a 38.1% increase in sales volume, supported by the addition of new customers during the year, expansion of its supply network to cover more ports, and a broader customer base that now includes bulk carriers and oil and gas tankers in addition to container liner operators.

However, due to challenging market conditions, CBL reported a net loss of USD 3.87 million in 2024, compared to a net income of USD 1.13 million in 2023.

This was mainly attributed to a 25.5% decrease in gross profit to USD 5.37 million in 2024 from USD 7.21 million in 2023 and a 56.8% rise in operating expenses to USD 8.70 million in 2024 from USD 5.55 million in 2023.

The company adopted a volume-driven growth strategy that involved offering more competitive pricing in a market characterised by intensified competition and pricing pressure.

“While this approach supported increased sales volume and market share, it also contributed to narrower profit margins,” it said.

In addition to reduced gross margins, the net loss was impacted by increased expenses for business expansion, biofuel operation, additional expenses to enhance ESG, and a rise in interest expenses. These were partially offset by a reduction in income tax expenses.

The financial outcome reflects both the dynamic nature of the bunkering industry and the company’s ongoing investment in client base development and geographic growth, which are expected to enhance long-term positioning as market conditions normalise.

Earnings per share (EPS) reflected this, decreasing to USD (0.136) in 2024 from USD 0.045 in 2023. Cash and cash equivalents increased by 8.3% to USD 8.02 million as of December 31, 2024 from USD 7.40 million as of December 31, 2023.

Business Expansion in Challenging Times

CBL International’s operational expansion was a key focus in 2024, particularly in a challenging industry environment marked by geopolitical tensions, such as the Red Sea crisis and broader Middle East tensions. The company grew its service network from 36 ports at the time of its IPO in March 2023 to over 60 ports by year-end 2024, covering Asia Pacific, Europe, Africa, and Central America. Revenue growth year-on-year was notable across China, Hong Kong, Malaysia, Singapore, and South Korea.

Key new ports included Mauritius, Panama, and India, enhancing its global reach. This expansion was supported by servicing nine of the world’s top 12 container shipping lines, representing nearly 60% of global container fleet capacity. The Company’s European expansion focused on strengthening cross-regional service offerings for Euro–Asia trade routes. Growth was supported by a stronger presence in the Amsterdam-Rotterdam-Antwerp (ARA) region and a new Ireland office established in late 2023, enhancing local sourcing capabilities.

Customer diversification was another priority, with the share of non-container liners in total revenue increased, and sales concentration among the top five customers declined in fiscal year 2024.

A significant highlight was the company’s push towards sustainability, with biofuel sales surging by 628.8% and volume by 603.0%. The introduction of B24 biofuel (76% fossil fuel, 24% used cooking oil methyl ester) in Hong Kong, China, and Malaysia reduced greenhouse gas emissions by 20%, supported by ISCC EU and ISCC Plus certifications secured in 2023. This aligns with global trends towards greener shipping solutions and positions CBL as a leader in sustainable fuel logistics.

Strategically, CBL enhanced its IT systems, implementing real-time order tracking, data analytics, and workflow automation to improve efficiency. Credit risk management was strengthened, and working capital management improved with increased factoring facilities and a cash balance rise, navigating macroeconomic challenges through pricing strategies and port network adjustments. Additionally, CBL expanded its funding sources by accessing capital markets, such as private placement, increasing financial flexibility to support growth initiatives.

CBL’s Outlook for the Future

Despite the net loss, CBL’s management remains optimistic about the future, viewing current industry challenges as an opportunity to build resilience and enhance customer loyalty.

While prudently evaluating the impact of the latest US tariff policy, among other macro incidents such as geopolitical tensions, regulatory changes, and shifting global trade dynamics, on the economy and the bunkering sector, CBL believes its broad global network, primarily focused on intra-Asia and Euro-Asia trade routes, helps mitigate potential adverse effects. Since the company has no operation on U.S. ports, the impact of such policies may be limited in the near future.

The company’s strategic expansion of ports, diversification of its client base, and commitment to sustainable initiatives are designed to position it for growth when market conditions improve.

By investing in new ports and expanding relationships with key industry players, CBL aims to secure long-term partnerships that will strengthen its market position as global trade stabilises and profitability improves.

Dr. Teck Lim Chia, Chairman and CEO of CBL International Limited, stated, “We are confident in our strategy to expand our service network, maximise sales volume and explore sustainable offerings, even in these challenging times.”

“Our investments in new ports, diversified clients, and sustainable fuels are building a foundation for future growth. We believe that by demonstrating our capabilities at present, we will earn customer loyalty that will yield substantial benefits as the market recovers, positioning CBL International for significant success in the years ahead.”

Looking ahead, CBL remains focused on expanding its market presence, particularly in biofuels, and enhancing its global supply network.

Chinese shipbuilder delivers CMA CGM’s Singapore-flagged LNG-powered boxship

Bureau Veritas Marine & Offshore (BV) on Wednesday (16 April) announced the successful delivery of CMA CGM SEINE, a new 24,000 TEU LNG dual-fuel container ship, by Hudong-Zhonghua Shipbuilding (HZSY).

This milestone marked the completion of the first vessel in a four-ship series, with BV providing classification and BV Solutions Marine & Offshore (BVS) providing advisory services.

It is CMA CGM’s first LNG-powered vessel flying the Singaporean flag with a capacity of 24,000 TEU.

It was reported that CMA CGM planned to expand its fleet and vessel tonnage, adding more vessels under the Singapore Registry of Ships. To support the transition to more sustainable fuels, CMA CGM said it would register and bunker alternative fuel vessels under the Singapore flag.

Xavier Leclercq, Vice President of CMA Ships, said: “Today’s delivery of the ‘CMA CGM SEINE’ featuring LNG as fuel at such a large scale, will remain a major landmark in the shipping world and embodies the engagement of the CMA CGM group toward an ambitious decarbonisation path, leading the way to our industry.”

Mr. Xiufeng ZHANG, Vice General Manger of Hudong-Zhonghua shipyard, said: “CMA CGM SEINE, as the lead ship of the four 24,000-TEU LNG dual-fuel powered container ships ordered by CMA Ships from our company, stands as a new-generation maritime ‘Green Giant’ and ‘super cargo hauler’.”

The vessel integrates a dual-fuel propulsion system supported by GTT Mark III membrane-type LNG bunker tanks, with a total capacity of 18,600 cubic meters, designed to enhance both environmental performance and operational efficiency.

Measuring 399.9 meters in length and 61.3 meters in beam, the vessel has a carrying capacity of 23,876 TEU and is equipped with a WinGD W12X92DF-2.0 dual-fuel main engine, incorporating the Intelligent Control by Exhaust Recycling (iCER) system.

This configuration significantly reduces methane emissions and enables compliance with IMO Tier III emission standards when operating in "Diesel + iCER mode".

BV worked closely with the engine manufacturer and the shipyard to test the parent engine and issued the Engine International Air Pollution Prevention (EIAPP) certificate, establishing a foundation for compliance across the series. The iCER system optimises energy efficiency, achieving an Energy Efficiency Design Index (EEDI) reduction well beyond the IMO’s Tier III standards.

To address the critical sloshing challenges in large-volume LNG bunker tanks, BVS performed direct computational fluid dynamics (CFD) simulations. The verified pressure data was provided to the design unit for structural strength checks, ensuring the safety of the cargo containment system and hull support structure.

The vessel features advanced technologies to boost operational performance and energy efficiency. Equipped with the SmartEye intelligent monitoring system and the TotalCommand full-control system, it achieves automated precision control during berthing, significantly reducing berthing time and enhancing port operations.

Energy efficiency is further improved by applying variable frequency drive (VFD) technology to the engine room fans and seawater cooling pumps. Meanwhile, the WinGD Data Collection Monitoring (DCM) system offers real-time tracking and analysis for the dual-fuel main engine, supporting operational optimisation.

BV also supported the upgrade of BV certified boil-off gas (BOG) compressors by conducting sea trial tests and re-issuing product certificates, facilitating seamless system commissioning and vessel delivery.
