Retrofitting can reduce CO2 emissions significantly

MAN Energy Solutions is implementing retrofitting technology to convert ship and power plant engines into future-ready machines capable of running on synthetic fuels – gaseous or liquid. Upgrade solutions and advanced customized retrofits by MAN PrimeServ open a world of options. They help you optimize reliability, efficiency, and performance; they lower maintenance expenses and add operational flexibility. More importantly, they enable you to comply with increasing environmental regulations. Retrofitting an engine extends the life cycle substantially, thus abating up to 97% of CO2 compared to e.g., building a new ship.

Keep your engines, systems, and equipment compliant and competitive 

Cargo ships and power plants are long-term investments. Retrofitted and modernized with high-value MAN Energy Solutions’ products, they become more sustainable, can continue to be used for decades, and are an attractive investment proposition.

Retrofits play an important role in the energy transition and are crucial for achieving a green fleet of ships or power plants that help to meet the targets of the Paris Agreement.

A recent study indicates that around 1,900 two-stroke and 1,800 four-stroke marine and power plant engines have the potential for a future fuels retrofit.

Maximize savings with future fuels through cutting-edge retrofit solutions 

Switching between different fuels is made easy with MAN dual fuel engines, as they are highly versatile and capable of utilizing both liquid and gaseous fuels. This flexibility empowers you to transition between fuels at your convenience, whether driven by factors like fuel costs or regulatory requirements. What's more, these engines can seamlessly switch between fuels even while operating, all without compromising engine performance. Should you wish to convert single fuel engines to dual fuel, please note that such a transformation may necessitate adjustments to your fuel supply infrastructure. Our team of MAN PrimeServ fuel experts is readily available to provide guidance and discuss the various possibilities. 

Converting existing engines to dual-fuel operation is crucial to decarbonize shipping because it’s a powerful measure that can be implemented quickly. This is an essential first step, as all such dual-fuel engines can also be enabled to operate on a range of carbon-neutral synthetic fuels, including synthetic natural gas (SNG), green ammonia and methanol. And from an economic perspective, retrofitting is much more efficient than installing a new engine or building a new ship

COSCO Extends Strategic Cooperation

New framework agreement facilitates further projects

At a recent ceremony in China, MAN Energy Solutions signed a framework agreement with COSCO Shipping Heavy Industry Co., Ltd. (CHI) regarding their future cooperation on decarbonisation retrofit projects.

Michael Petersen – Senior Vice President, Head of PrimeServ Denmark – signed the agreement on behalf of MAN Energy Solutions, with Guo Zhiqiang – Deputy General Manager, CHI Commercial Headquarters – doing so for CHI.

Guo Zhiqiang said: “I am pleased to announce that CHI and MAN Energy Solutions, having served shared clients in their respective domains, are now forging a closer collaboration in vessel decarbonisation. Starting today, our integrated one-stop solutions will inject fresh impetus into the green transition of the global maritime industry.”

Petersen said: “This frame agreement facilitates MAN Energy Solutions’ partnership with CHI, one of the largest repair-yard groups in the world. The agreement means that we can join forces on many future projects to ensure the decarbonisation of the existing commercial fleet worldwide. Today, there are some 4,500 vessels globally with the potential to benefit from changing their current bunker fuel to more environmentally-friendly options. We look forward to working with CHI to deliver new decarbonisation solutions to the maritime industry.”

The new framework agreement provides for the retrofitting of existing ships to operation on new alternative fuels like methane, methanol and ammonia – all fuels that can be produced in a sustainable way through power-to-X processes. MAN Energy Solutions will provide advanced engine-retrofit technology and digital energy-efficiency solutions, while CHI will leverage its rich EPC (Engineering, Procurement, and Construction) experience in large-scale ship modification projects.

With five ship-repair yards, CHI has the capacity to repair and modify approximately 1,500 ships annually. This collaboration will integrate MAN PrimeServ’s cutting-edge, dual-fuel engine technology with CHI's repair and modification capabilities to decarbonise the merchant fleet globally.

MAN Energy Solutions views the new agreement as a natural development stemming from the companies’ strong relationship. In this respect, MAN Energy Solutions and CHI are already working together on two major projects for two world-leading container-ship owners.

Frequently Asked Questions

Can I retrofit older vessels, or are retrofits primarily for newer ships?

Retrofits benefit vessels of all ages, not just newer ones. It extends the operational life of vessels and ensures compliance with evolving industry as well as environmental standards. Retrofit options depend on the vessel's age, condition, and design, but older ships can benefit from retrofits as well.

What are the environmental and regulatory benefits of upgrading to cleaner technologies in marine applications?

Upgrading to cleaner technologies in marine applications provides numerous environmental and regulatory benefits. This includes significant reductions in emissions of air pollutants, compliance with international regulations, improved fuel efficiency, and noise reduction. Moreover, cleaner technologies enhance safety, contribute to long-term sustainability by reducing carbon emissions, and open access to environmentally conscious markets.

What is the expected downtime during a retrofit or upgrade project?

The expected downtime during a retrofit or upgrade project varies significantly based on factors like the project’s size, customization, location, regulatory requirements, and unforeseen issues. Downtime can range from a few weeks to several months. Efficient project planning can help reduce downtime, while unforeseen problems may extend it. The goal is to strike a balance between minimizing downtime and ensuring high-quality and safe work.
