IACS Fleet Dominates Global Shipping in Tonnage and Deadweight
March 31, 2025 – The International Association of Classification Societies (IACS) continues to play a crucial role in the global maritime industry, with its classed vessels accounting for a significant share of the world’s fleet in terms of gross tonnage and deadweight. Recent data from Lloyd’s List Intelligence highlights IACS’s dominance in global shipping, reinforcing its influence on maritime safety and operational standards.
According to the latest figures, the IACS-classed fleet boasts a total gross tonnage of 1,391,219,222, compared to the global fleet’s 1,484,552,948. Similarly, in terms of deadweight, IACS-classed vessels collectively represent 2,022,848,075, whereas the total global fleet stands at 2,160,800,857. While the total number of IACS-classed vessels is 57,283, the global fleet comprises 73,148 ships.
The data suggests that while IACS-classed vessels are fewer in number, they are generally larger and more tonnage-heavy, playing a significant role in global shipping capacity. As the industry continues to evolve with new regulations and technological advancements, classification societies like IACS remain pivotal in maintaining safety, efficiency, and sustainability across the maritime sector.
With increasing global trade demands and stricter environmental regulations, the role of classification societies in ensuring compliance and operational excellence has never been more vital. This latest report underscores the continued trust and reliance on IACS-classed ships in shaping the future of maritime transportation.
