Columbia Group says dual-fuel ships will define the next decade of shipping, as the absence of scalable zero-carbon alternatives positions LNG-powered vessels as the industry's most viable solution.

The ship management company said dual-fuel ships are expected to account for around half of global new-build orders by the end of 2025, with LNG propulsion powering nearly 70% of those vessels. Columbia Group noted that this surge reflects the industry's response to tightening regulations and uncertainty over future fuels.

"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," said Duncan McLennan, Group Director, Technical at Columbia Shipmanagement. "Dual-fuel designs also give operators flexibility, reducing exposure to regulatory and commercial risks as markets evolve."

However, Columbia Group highlighted that dual-fuel ships also introduce operational challenges. The company said systems are more complex, capital costs are higher, and fuel management is more demanding than on conventional vessels.

"Balancing LNG with conventional fuels, such as VLSFO, requires careful planning and operational oversight," McLennan added. "It is not just about building these ships, but about ensuring they are run safely, efficiently, and in full compliance."

In response, Columbia Group said it 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.

"Training must go beyond textbooks," McLennan added. "Our experience managing dual-fuel tankers shows that practical preparation is essential to ensure safe and efficient operations."

The company said it is also investing in digital optimisation through platforms that 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.

"Dual-fuel vessels are complex machines," said Mark O'Neil, President and CEO of Columbia Group. "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."

O'Neil concluded that while dual-fuel ships are not the ultimate solution, they serve as a 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."

Columbia Group has provided ship management and crew management services for over 45 years, with more than 40 management and representative offices, crew agencies and training centres worldwide.
