Regulatory clarity, decarbonisation and digitalisation were central to discussions as more than 85 representatives of shipbuilders, shipowners and classification societies, together with invited observers, met in Tokyo on 28–29 October for Tripartite 2026. BIMCO was this year’s organising association.
The annual summit examined how the industry can develop safe, secure and environmentally sustainable ships amid technological change and regulatory uncertainty. Participants reaffirmed their support for the International Maritime Organization (IMO) as shipping’s global regulator and stressed that close cooperation between regulators, shipbuilders, shipowners and classification societies is essential to making new requirements clear and workable.
“Tripartite brings together shipbuilders, shipowners and classification societies to discuss contemporary issues related to new ships. By sharing hands-on experience and working together through this unique forum, we contribute with realistic solutions that can be implemented effectively across the industry to deliver on the ambitions of the regulators at IMO,” - Lars Robert Pedersen, BIMCO Deputy Secretary General
Clearer rules for new technologies and fuels
Discussions covered fuel efficiency, new technologies and practical approaches to reducing greenhouse gas emissions. Participants considered how safety regulation can keep pace with new fuels and novel propulsion systems, alongside the need for greater harmonisation across regulatory requirements and progress towards a single global decarbonisation framework.
A high-level panel explored how the industry can build the next generation of ships despite uncertainty over future regulation. A dedicated session also examined nuclear technology and its potential role in maritime decarbonisation.
Better data exchange and less administration
Digitalisation discussions focused on reducing administrative burdens, improving information exchange between ship and shore, and using data more effectively to support safe and efficient operations. Participants also discussed data interoperability between ships, shore-based teams and other stakeholders, and a common environmental reporting protocol covering local, regional and commercial requirements. Environmental sessions addressed current compliance challenges and emerging regulatory requirements.
Turning discussions into practical outcomes
Tripartite’s working groups will continue to develop solutions and recommendations on technical, safety, environmental and digitalisation issues. Their work supports the safe, sustainable and efficient operation of ships and related regulatory developments at IMO.
The forum has supported IMO’s work for more than two decades, contributing to Common Structural Rules for bulk carriers and tankers, permanent means of access on tankers, and mandatory coatings for ballast and cargo tanks.
The participating organisations are ASEF, BIMCO, CESA, IACS, ICS, INTERCARGO, INTERTANKO and SEA Europe. This year’s summit was also sponsored and supported by ClassNK, the Japanese Shipowners’ Association and the Shipbuilders’ Association of Japan. The next Tripartite forum will take place in China in the fourth quarter of 2027.
