As the shipping industry searches for viable low-carbon solutions, dual-fuel vessels are emerging as the bridge technology of choice. With no scalable zero-carbon alternative currently available, LNG-powered ships are poised to dominate the next ten years of global fleet expansion.
Columbia Shipmanagement projects that by the end of 2025, dual-fuel vessels will represent around half of all newbuild orders worldwide, with LNG propulsion powering nearly 70% of those ships. This surge reflects the sector’s pragmatic response to tightening emissions regulations and uncertainty over future fuel options.
“Shipowners and operators face increasingly stringent legislation,” explains Duncan McLennan, Columbia Group’s Group Director, Technical. “LNG has become a practical bridge, enabling compliance today while providing confidence for the decade ahead.” He notes that dual-fuel designs also offer flexibility, helping operators mitigate regulatory and commercial risks as markets evolve.
However, these vessels bring new operational challenges. Systems are more complex, capital costs are higher, and managing dual fuels—particularly balancing LNG with conventional fuels such as VLSFO—demands careful planning and skilled oversight.
To address this, Columbia Group has prioritized crew training, expanding programs to ensure seafarers can operate dual-fuel systems safely and efficiently. Simulator-based exercises now complement classroom learning, covering fuel switching, cryogenic handling, and emergency procedures.
“Training cannot be theoretical alone,” McLennan emphasizes. “Practical experience is essential for safe, efficient operations. Dual-fuel ships are not the ultimate solution, but they are a critical bridge toward a more sustainable future for shipping.”
