Mainly IMO and EU are forcing shipping to decarbonize- fuel costs are going to raise and hefty penalties will apply for less efficient and vessels, which can’t burn low-emission fuels. Heavy lifters are unfortunately difficult to decarbonize, as they don’t have space to carry alternative fuels, nevertheless the industry is working new solutions. Beside of optimizing fuel efficiency and flexibility, focus is put on maximizing vessel’s transport capabilities for newbuilds by design and operational measures.
