The multipurpose and heavy-lift fleet is benefiting from a white-hot carrier market and a consolidating sector but facing tough, multimillion-dollar decisions on fleet renewal. After years of overcapacity in the sector, a looming vessel shortage in an already-tight market is rattling nerves across the project cargo supply chain. Why are so few new vessels on order? A lack of yard space and high building costs are significant factors, but looming even larger are questions about what designs, engines, and technology will work for vessels expected to operate for 20 years or more in a low-carbon or carbon-neutral future. What will regulators and shippers require from their carriers in terms of low-carbon footprints and Environmental, Social, and Governance criteria? And what should or can carriers require of their clients? This incisive discussion with four executives from leading multipurpose carriers will analyze these questions and more.
