Eco-Trends in Energy Solutions on Cruise Ships

Abstract

Today the world’s largest cruise ships can take on board more than 6000 passengers and almost 3000 crew members. Managing a significant number of people and all equipment and operations on ships requires the delivery of tens of thousands of kilowatts, which poses a huge challenge for both cruise ship builders and ports supporting these ships as well as for ship owners themselves, as the costs involved represent the largest share in the structure of expenditure in cruise shipping companies. In recent years, various communities and institutions, including the International Maritime Organisation and the European Union, exert pressure on cruise ship owners to use green renewable energy solutions. For these reasons, cruise ship owners are constantly looking for cost-effective and environmentally responsible solutions regarding new energy sources for ships. The aim of this paper is to identify modern solutions applied on cruise ships in the field of energy generation and to indicate benefits for the environment and ship owners in this respect. The following research questions were formulated: (1) What factors force cruise ship owners to introduce modern energy policy solutions? (2) What kind of green energy solutions are currently used on cruise ships? (3) What kind of renewable energy solutions do cruise ship owners use to reduce energy consumption on board cruise ships? The research was conducted by applying a few research methods, i.e., desk research method and exploration method, critical and comparative analysis, and also inductive and deductive reasoning. The results of this research can provide an interesting source of information for cruise ship owners, cruise seaport authorities, and shipyards involved in the construction of new vessels.
