Ship manager Columbia Group predicts that dual-fuel ships will define the next decade of shipping, as the absence of a scalable zero-carbon alternative leaves LNG-powered vessels as the industry’s most viable solution.
As we near the end of 2025, dual-fuel ships will have accounted for around half of global newbuild orders, with LNG propulsion powering nearly 70% of those vessels. Columbia Group believes this surge reflects the industry’s pragmatic response to tightening regulations and uncertainty over future fuels.
Duncan McLennan, Group Technical Director, Columbia Shipmanagement, said: “Owners and operators face increasing legislation, and LNG in particular has emerged as a bridging technology that allows compliance with today’s standards while providing confidence for the next decade. Dual-fuel designs also give operators flexibility, reducing exposure to regulatory and commercial risks as markets evolve.”
While dual-fuel ships bring opportunities, Columbia Group highlights they also introduce challenges. Systems are more complex, capital costs are higher, and fuel management is significantly more demanding than on conventional vessels.
McLennan added: “Balancing LNG with conventional fuels, such as VLSFO, requires careful planning and operational oversight,. It is not just about building these ships, but about ensuring they are run safely, efficiently, and in full compliance.”
In response to this, Columbia Group has made crew training a priority, expanding programmes to ensure seafarers are confident in handling dual-fuel systems. Simulator-based training now complements classroom learning, covering fuel switching, cryogenic handling, and emergency procedures.
McLennan said: “Training must go beyond textbooks. Our experience managing dual-fuel tankers shows that practical preparation is essential to ensure safe and efficient operations.”
Columbia is investing in digital optimisation. Platforms such as EngineLink + POCR support fuel mode optimisation, predictive maintenance, and emissions reporting. These tools provide real-time comparisons of LNG versus conventional fuels, detect engine anomalies, and capture methane slip data for regulatory compliance.
Mark O’Neil, President and CEO, Columbia Group, concluded: “Dual-fuel vessels are complex machines. Technology alone cannot manage that complexity. It requires the right blend of human skill, operational expertise, and digital support. At Columbia, our mission is to ensure all three work together to deliver safe, sustainable, and commercially viable outcomes. Whilst dual-fuel ships are not the ultimate solution, they do serve as a critical bridge. With the right management, they give shipowners the opportunity to operate more safely, sustainably, and efficiently as the industry awaits a more widely accepted alternative fuel solution.”
