Classification society DNV has launched a report to help shipowners identify energy-efficiency measures and technologies.
DNV’s latest report, Energy-efficiency measures and technologies – Key solutions and strategies for Maritime’s decarbonization journey, offers more than 40 energy-efficiency measures, specifying fuel-saving effects, cost figures, and suitability for specific ship types.
“The decarbonisation of shipping is one of our greatest challenges. While transitioning to carbon-neutral fuels is essential, supply and cost remain key barriers,” said Knut Ørbeck-Nilssen, ceo at DNV Maritime. “Energy-efficiency measures can not only cut emissions in the short term but also support the adoption of alternative fuels by reducing overall fuel demand and operational costs.”
DNV’s report focuses on how these measures can help shipowners ahere to short- and mid-term regulatory requirements, gain a competitive edge, and guarantee profitable operations into the future. It also homes in on how data-driven decision-making can enhance fuel savings, while reaffirming cybersecurity.
A three-step approach for managing decarbonisation risks is outlined in the report: defining a greenhouse gas (GHG) trajectory and goals; assessing pathways for meeting these goals; and developing a fleet decarbonisation strategy and plan.
“While there’s no one-size-fits-all solution, improving onboard efficiency reduces emissions in the short term and accelerates low-carbon fuel adoption in the long term. Every percentage of fuel saved, whether conventional or alternative, translates into significant cost savings,” added Jason Stefanatos, global decarbonisation director at DNV Maritime.
Towards the end of last year, DNV published competence standards for recommended practice for methanol and ammonia fuel use.
