DNV: How to develop and implement a successful decarbonization strategy

Classification society DNV on Tuesday (16 July) published a Maritime Impact article on tanker owner International Seaways’s decarbonization journey with the support of DNV:

International Seaways, Inc. embarked on an ambitious journey to put its entire tanker fleet on course for decarbonization, supported by DNV. An overall strategy and decarbonization plans for all vessels will help the company to achieve regulatory compliance in a cost-effective way while reducing business risk.

Achieving greenhouse gas emission compliance for an entire fleet of vessels can be a very complex task, both methodically and financially, and knowing where to start is not the easiest part of it. This is why DNV’s Maritime Advisory team offers a structured approach that helps shipowners develop a fleet-wide decarbonization plan – and engage the organization to support it.

A fast follower: Putting sustainability centre stage

International Seaways, Inc. (INSW) is a well-known New York-based tanker owner with a fleet of roughly 80 vessels of various types and sizes. The company has worked with DNV for many years and turned to DNV for support with its decarbonization strategy and plans. “We are a listed public company, so we have to be very thoughtful about how we invest our money,” explains William Nugent, Senior Vice President and Chief Technical and Sustainability Officer at International Seaways. “Our shareholders expect us to be careful stewards of their investments.”

Seeing the broader trends in the industry and the global drive to decarbonize, INSW wants to be “a fast follower”, he adds. “This means that we need to look at how our existing and future fleet matches IMO’s and Europe’s decarbonization intentions and especially those of our stakeholders.” Sustainability criteria are typically embedded in today’s finance agreements, he points out, lauding the Poseidon Principles, which have helped create a level playing field for the shipping world.

DNV’s strategy report: Guiding INSW towards compliance

The purpose of the fleet-wide decarbonization strategy and plans DNV developed jointly with INSW was to enable the company to meet or exceed the IMO decarbonization trajectories and EU regulations in an economically feasible manner while minimizing business risk. DNV delivered a strategy report to provide INSW with a solid understanding of the regulatory environment and the available options to achieve compliance, including operational optimization recommendations for the years to come. Furthermore, the delivery included a fuel performance management report as well as a roadmap and capital expenditure schedule for every single vessel, delivered on DNV’s Veracity platform.

Periodical updates keep decarbonization plans relevant

Lois Zabrocky, President and Chief Executive Officer of International Seaways, summarizes the objectives: “Of course, we want a plan to reduce our emissions and extend the lifetime of the vessels as much as possible. Today, we have a plan to … look at the trajectory of our emissions and all the available opportunities for us to decarbonize.”

As a living document, the decarbonization plan is reviewed and updated periodically with help from DNV as the INSW organization builds knowledge, experience and confidence.

Alignment throughout the enterprise and beyond

“The first step we embarked on together with DNV was taking the temperature of the organization,” recalls Nugent. All parts of the INSW organization from the CEO down to the crews, along with external partners such as commercial vessel management and charterers, were asked to participate in surveys to provide their views of INSW, their current decarbonization efforts and related questions. “We also conducted a technical review across the fleet and updated our educational processes for the whole organization around what decarbonization means, the goals, issues and challenges,” says Nugent.

Turning evaluation insights into actionable decarbonization plans

“This stepwise effort, guided by DNV, was thoughtful, well-timed and in-depth; it highlighted areas where we were very strong and others where we had work to do. It was presented in a way that was clear, concise and solution-oriented.” The resulting insights enabled INSW to benchmark the company against decarbonization best practices and put in place the decision tools to change the internal dialogue around decarbonization, which took many workshops and meetings involving all levels of the organization. “DNV took an industry’s worth of insights, feedback and knowledge and turned it into something very specific and actionable for International Seaways,” says Nugent.

World Fuel and partners complete first green methanol bunkering of car carrier in Shanghai

Marine fuel provider World Fuel on Tuesday (21 July) said it successfully completed the first green methanol bunkering of M/V Arctic Tern, with EUKOR Car Carriers and SIPG Energy at the Port of Shanghai. 

Arctic Tern is the first vessel in the new Shaper Class series of car carriers. 

The operation involved the delivery of approximately 2,800 MT of green methanol to Arctic Tern via a ship-to-ship transfer using SIPG Energy’s dedicated methanol bunkering vessel M/V Hai Gang Zhi Yuan, the largest vessel of its kind in operation. 

The bunkering operation was carried out at Haitong Terminal, Waigaoqiao Port Area, Shanghai Port, with cargo handling operations conducted simultaneously during bunkering.

This marks EUKOR Car Carriers’ first green methanol operation and the first time Arctic Tern has bunkered methanol since its delivery on 9 July. The operation marked the first bunkering at Shanghai Port of green methanol produced locally in Shanghai for an international PCTC operator. 

It also demonstrated the city’s integrated green methanol value chain, spanning local production, storage and bunkering, and established a replicable “Shanghai Model” for green methanol supply.

World Fuel arranged the supply and delivery of the fuel on behalf of EUKOR Car Carriers, working with SIPG Energy as the physical supplier at the Port of Shanghai.

The green methanol supplied was produced from municipal solid waste, ISCC-EU certified, and had a carbon intensity value below 25 gCO₂e/MJ.

Arctic Tern is the first of fourteen Shaper Class vessels ordered by Wallenius Wilhelmsen. With a capacity of 9,300 car equivalent units and methanol dual-fuel capability, the vessel will be operated by EUKOR Car Carriers, jointly owned by Wallenius Wilhelmsen and Hyundai Motor Group. Following her first green methanol bunkering, Arctic Tern will continue her maiden voyage from Asia to Europe.

Xavier Leroi, COO Shipping Services at Wallenius Wilhelmsen and CEO of EUKOR Car Carriers, said: “Completing Arctic Tern’s first green methanol bunkering shortly after delivery is a significant milestone towards our decarbonisation ambition for both EUKOR Car Carriers and Wallenius Wilhelmsen. It demonstrates how investments in next-generation vessel technology and fuel flexibility are being translated into real-world operations. 

“This achievement reflects the strong collaboration between all parties involved. Together, we have shown how partnerships across the maritime value chain can help make lower-emission fuels available and operationally viable at scale.”

Mark Tamsitt, SVP Global Marine Sales at World Fuel, said, “The first bunkering event with a new fuel is a significant moment for any shipowner, and our role is to make it as seamless as possible. By connecting EUKOR Car Carriers with SIPG Energy’s proven green methanol capability at the Port of Shanghai, we were able to deliver on reliable supply, fuel quality, and safe processes. As more of our customers bring methanol dual-fuel tonnage into service, we are committed to being the partner that makes these kinds of operations routine.”

Mr. Zhang Da, General Manager of SIPG Energy, said, “Welcoming Arctic Tern to the Port of Shanghai for her first green methanol bunkering demonstrates the strength and maturity of our supply capability. Building on our well-established methanol ship-to-ship bunkering services for container vessels, we have already extended such services to pure car and truck carriers (PCTCs). This bunkering sets a new record for the largest single SIMOPs green methanol bunkering for PCTCs in China, marking another step in building Shanghai’s position as a global green energy hub for international shipping.”

This operation follows Wallenius Wilhelmsen’s announcement on 9 July that Arctic Tern would complete her first methanol bunkering shortly after delivery. The vessel entered service on routes between Asia and Europe immediately following handover from China Merchants Jinling Shipyard in Nanjing.

HPA and MB Energy develop safety concept for STS ammonia bunkering

The Hamburg Port Authority (HPA) and integrated energy company MB Energy on Tuesday (21 July) said they have completed a comprehensive risk analysis and developed a dedicated safety concept for ship-to-ship ammonia bunkering.

MB Energy said the analysis lays the groundwork for the safe introduction of ammonia as a future marine fuel.

“With our planned ammonia import terminal in Hamburg-Blumensand, MB Energy intends to provide the reliable land side supply infrastructure needed to support this transition across northern German ports,” it said in a social media post. 

Mabanaft Group was renamed to MB Energy last year and merged over 50 existing brands under one identity. 

Separately, HPA said the Port of Hamburg will become “bunker ready” for ammonia, laying the groundwork for safe and reliable ammonia bunkering in the future.

“The focus is in particular on container ships, cruise ships as well as RoRo and ConRo (Container/RoRo) ships,” it said. 

“We expect ammonia to establish itself as an alternative marine marine fuel in the coming years. With our preparatory work, we are already creating the conditions to welcome the first ammonia-powered ships in Hamburg and to bunker them safely.:

HPA added that the import terminal for ammonia planned by MB Energy from 2029 will make a decisive contribution to ensuring the reliable availability of ammonia as a bunker fuel in northern German ports in the long term. 

“The use of an ammonia bunker barge is considered a possible addition to the landside infrastructure to enable ship bunkering in the port and beyond in the future,” it said.

Global Centre for Maritime Decarbonisation (GCMD) on Wednesday (21 July) said Project CAPTURED has achieved two regulatory milestones that strengthen the commercial case for onboard carbon capture and storage (OCCS).

This comes following its world’s first demonstration of an end-to-end value chain for onboard captured and liquefied CO2 (LCO2).

Completed in June 2025, the pilot showed that CO2 captured onboard a vessel can be offloaded ship-to-ship, transported overland and permanently bound through carbon mineralisation—a process that converts captured CO₂ into stable materials for industrial use.

The CO2 captured onboard during Project CAPTURED has been formally recognised for compliance under the European Union Emissions Trading System (EU ETS). This means the verified tonnage of captured CO2 can be deducted from emissions requiring the surrender of EU Allowances (EUAs).

To qualify for this recognition, the CO2 must be chemically bound permanently in eligible products. Project CAPTURED demonstrated that CO2 captured onboard vessels can meet this requirement through carbon mineralisation.

The data and learnings from the same demonstration formed the basis of a proposal submitted to MEPC 84. This proposal received in-principle support from the International Maritime Organization (IMO) for recognising carbon mineralisation as a form of permanent CO₂ storage.

Complementing geological sequestration, which is already accepted by the IMO, this recognition broadens the downstream options for CO2 captured onboard vessels, and supports the development of maritime carbon value chains. Beyond providing a permanent storage pathway, carbon mineralisation also creates the potential for captured CO2 to serve not only as a waste stream requiring permanent storage, but also as a feedstock for industrial applications through carbon mineralisation, extending emissions reductions beyond the shipping value chain.

Professor Lynn Loo, CEO, GCMD, said, “Project CAPTURED has moved OCCS beyond technical demonstration. The acceptance of the EU ETS deduction gives captured CO₂ a compliance value. At the same time, IMO’s in-principle support for carbon mineralisation will help clarify how captured CO2 can be treated after it leaves the vessel. Together, these milestones turn a pilot into a verified reference case for maritime carbon logistics, one that links regulatory recognition, commercial value and emissions impact.”
