The last meeting of the Marine Environment Protection Committee (MEPC 80) of the International Maritime Organization (IMO) in July 2023 will alter the course of maritime history. Adopted during this meeting, the IMO Strategy on Reducing Greenhouse Gas (GHG) Emissions from Ships was accepted by the member states. They moved the deadline for meeting the zero-emission goals from 2100 to 2050. under 2050, the marine sector is required under IMO environmental requirements to achieve carbon neutrality.

The Next Step After Eexi and Eedi Environmental Regulations
The IMO is urging immediate measures to combat the pressing issue of climate change. The journey towards transforming the marine industry into a green and sustainable sector cannot be accomplished overnight. Instead, IMO has been introducing new regulations that are gradually growing more stringent over a decade.
After the introduction of the EEDI (Energy Efficiency Design Index) environmental regulations in 2014, the next significant milestone on this journey is the EEXI (Energy Efficiency Existing Ship Index), which came into effect in 2023. These regulations pertain to the reduction of carbon emissions for all vessels, both existing and those yet to be built.
So, what’s the issue?
The competitive environment that ultimately came down to “survival of the fittest” and consolidation influenced the maritime industry landscape. Shipbuilders are required to meet deadlines, budgets, and environmental requirements while producing intelligent vessels that employ cutting-edge technology. However, officials aren’t the only ones emphasizing sustainability. Not to mention, customers want their goods to be delivered by environmentally friendly means, financiers are searching for environmentally friendly assets, and ports all over the world are beginning to fine non-green ships. So, how do you construct a vessel that will function for 20–30 years in a setting where it’s unclear what will occur in the next five years?
In the Sea of Uncertainty
The marine sector is like to being at sea, gazing into an uncertain future. Perhaps in a sector as heavily regulated as the marine industry, you shouldn’t expect to find certainty. But the ambiguity stems from a lack of understanding. The industry is focused on achieving zero emissions and moving away from traditional hazardous fuels like heavy fuel oil and marine diesel oil, but there is still a significant question that remains unsolved: “What is the fuel of the future?” Furthermore, no workable long-term remedies exist at this time.
The 10 Maritime Fuels Fighting for the Top Spot
At present, the top ten options are the main topic of discussion when it comes to the future of marine fuel. In the marine sector, there are no firm indicators as to which fuel will be “the one,” in contrast to the automotive sector, where the argument boils down to two basic options: hydrogen or electric. Sadly, there are a lot of advantages and disadvantages to every approach. According to statistics compiled by DNV and Statista with ID 1364303, the most popular alternative fuels for ships in service in 2022 were LNG, battery/hybrid, LPG, and methanol. Furthermore, in 2022, the portion in the order book remains unchanged.
Start With Integrated Ship Design to Enable Green Innovation
The only option in today’s cutting edge technology landscape is to start using digital ship development technologies right away. However, the question remains as to what problems these technologies may solve and how closely related they are. Integrated ship design holds the key to the future, providing a streamlined, collaborative environment for the construction of digital twins of vessels. By doing this, the businesses gain the ability to forecast performance and take prompt, informed decisions that maximize designs before a vessel is built. This gives space to investigate the designs and quicken breakthroughs.
The industry tools offered by the Simcenter portfolio enable a thorough examination of various propulsion choices, alternative systems and fuels, and layouts. It also offers insights into the performance and emissions of each configuration. It is imperative to conduct this type of analysis prior to agreeing to a contract for a new vessel.
In One Boat Together: Classification Societies, Shipbuilders, and Shipowners
Ship design teams and shipbuilders do not have exclusive access to comprehensive design tools that enable informed decisions as soon as possible. Class societies and shipowners must also make informed decisions. Class societies are seen as leaders in the industry, setting the standard for others to follow. They were early adopters of simulations for powering and have now embraced the power of CFD simulations and integrated systems. This integrated approach allows them to provide valuable and informed insights to ship owners when signing a contract for new construction. Ship owners are also beginning to realize the importance of in-house capabilities that can be used to evaluate, understand, and adjust performance on an individual vessel or fleet level by evaluating and identifying different propulsion configurations.
