Kawasaki Heavy Industries on Wednesday (21 August) announced that it has discovered misconduct regarding shop trials conducted for its two-stroke diesel engines for commercial marine vessels.

The firm became the third major Japanese firm to have altered test results of its marine engines after Hitachi Zosen Corporation and IHI Corporation came clean in July and April respectively. 

The company said it took the incident very seriously and offered its assurances to customers and other stakeholders that every effort will be made to ensure it does not happen again.

“The company is currently examining whether this matter will impact its financial results and will immediately issue notification should such an impact be confirmed,” it said. 

On July 5, 2024, Japan’s Ministry of Land, Infrastructure, Transport and Tourism requested that the Company conduct a fact-finding investigation into whether there had been misconduct in its nitrogen oxide (NOx) emissions verification tests for its marine diesel engines. 

The company responded by carrying out an internal investigation of such engines, which are subject to International Maritime Organization (IMO) Tier 1 and other regulations governing NOx emissions from marine engines. This investigation uncovered misconduct during shop trials, including verification tests for NOx emissions.

Specifically, the investigation confirmed that shop trial fuel consumption rates for the company’s marine diesel engines had been altered through the manipulation of testing equipment to keep values within the permissible range of customer specifications and to reduce data discrepancies. 

This has the potential to impact NOx emissions calculations for these engines.

As of the date of this news release, there have been no confirmed cases of this having affected the safety of these engines during sea trials or actual use.

Misconduct was confirmed on June 12, 2024. Subsequently, the company carried out a thorough internal investigation of 674 engines subject to NOx emissions regulations for marine vessels the keels of which were laid on or after January 1, 2000, as shown in the table below. 

This investigation confirmed that data had been altered for the 673 two-stroke diesel engines for commercial marine vessels. No data alterations were found to have been made for the single four-stroke engine.

Number of Engines Investigated

Actions to Be Taken

The company will further investigate and report on the effect of this incident on its compliance with NOx and CO2 emissions regulations set by the IMO. 

Additionally, a special investigative committee of third-party experts will be established promptly to further probe the details of this incident and analyse the root causes, as well as to formulate and implement measures to prevent recurrence.

DNV awards Cummins AiP for methanol-ready QSK60 marine engines

Cummins on Thursday (6 March) said it has received Approval in Principle (AiP) from DNV for its methanol-ready QSK60 IMO II and IMO III marine engines.

The engines are available in power ratings from 2000 to 2700 hp (1491 - 2013 kW). 

The company said the approval, granted in June 2024, validated Cummins' retrofittable methanol dual-fuel solution for the global marine market, ensuring compliance with the highest standards of safety and performance.

Following extensive field testing, Cummins plans to launch the retrofit kits for the QSK60 post-2028 to align with market demand and infrastructure readiness. Designed for diesel-electric systems, these kits can be integrated with battery technology to optimize efficiency and sustainability.

Dawn Wehr, Cummins Executive Director – Strategy, Product Planning & Digital, said: “Using a retrofittable solution dismisses the need for a major vessel overhaul and creates an immediate positive impact on carbon-emissions reduction. With our continual work on developing solutions for other alcohol fuels, including ethanol, we are committed to providing solutions that work for different operations and fuel infrastructure availabilities to ensure ease of adoption.”

The approval builds on Cummins' August 2023 announcement permitting the use of renewable diesel, such as hydrotreated vegetable oil (HVO), across its high-horsepower engine range. By leveraging renewable diesel in dual-fuel solutions, ship operators can make significant progress towards reducing carbon emissions.

LR report reveals resurgence of LNG retrofits as short-term carbon reduction solutions

LR report reveals resurgence of LNG retrofits as short-term carbon reduction solutions

Classification society Lloyd’s Register’s (LR) on Thursday (6 March) said its latest Engine Retrofit Report revealed a surprising development in 2024 – the resurgence of LNG retrofits as shipowners sought immediate carbon reductions to navigate regulatory requirements.

“More than 305 LNG-fuelled ships were ordered last year, accounting for approximately 14% of newbuilding orders, significantly outpacing methanol and ammonia alternatives,” it said. 

While LNG offers a near-term compliance solution, the report warned that deeper emissions reductions will be necessary beyond the next decade. 

“Methane emissions and the long-term availability of bio- and e-LNG remain challenges, but with zero-emission fuel supply chains still in their infancy, many operators see LNG as the most viable retrofit option today,” LR added.

The report revealed that while the maritime industry has made strides in its ability to execute ship engine retrofits for alternative fuels, a critical lack of supply-side incentives threatens to delay progress.  

Since LR's initial report in 2023, the industry has seen the completion of the first methanol fuel conversions since 2015 and a continued expansion of shipyards with retrofit capabilities.  

However, the new report emphasises that the incentives needed to accelerate the adoption of alternative fuels are evolving at a slower pace. Despite regulatory drivers such as the EU’s FuelEU Maritime and Emissions Trading System (ETS), which impose penalties for carbon emissions, demand for alternative fuels remains low due to an absence of strong incentives for fuel producers.

Supply chain readiness is another important factor highlighted in the report. It warns that without improved coordination between engine manufacturers, fuel system suppliers, and shipyards, lead times for conversion projects could stretch beyond 18 months. On the regulatory front, recent amendments to the MARPOL Annex VI NOx Technical Code are expected to ease certification challenges for converted engines.  

Another significant issue identified in the initial report was the limited capacity of shipyards capable of undertaking alternative fuel conversions. While the number of capable yards has increased (around 16 shipyards, mainly in China and the Middle East), the latest report identifies current retrofit capacity at approximately 465 vessel conversions annually—well below the projected peak requirement of over 1,000 conversions per year.  

Despite a slow evolution of new retrofit orders in 2024, engine designers are proactively preparing for future market demands. The relatively shorter lead time for retrofit projects than newbuilds mean that more projects for completion in 2026 and 2027 could be announced in 2025.  

In response to the initial report that identified shipyard capability as a potential obstacle to retrofits, LR has developed a methodology for evaluating potential shipyard candidates. This provides shipowners with confidence that chosen partners can fulfil retrofit project requirements.  

Claudene Sharp-Patel, LR's Global Technical Director said: “LR’s new Engine Retrofit Report demonstrates that while technology and regulations are evolving, decisive action is needed to secure the future fuel landscape. The technology and shipyard capacity to retrofit vessels is improving, but without decisive action to scale up alternative fuel supply chains, shipowners will face increasing compliance costs and operational uncertainty. We need greater regulatory clarity and investment to bridge the gap between ambition and action.”
