A Techno-Economic Analysis of a Cargo Ship Using Flettner Rotors

In the last twenty years, global shipping transport demand has strongly increased (around 4% per year since 1990s), together with request for new green propulsion technologies to break down carbon emissions and face costs deriving from usage of conventional diesel fuels. Flettner rotors (hereafter: FRs) have been identified by several researchers as a promising solution exploit wind energy on commercial ships, reducing fuel consumption. The present work presents six-degree-of-freedom (6DOF) ship performance model set up evaluate best way using pair rotors. study analyses this system in consideration weather sea conditions, evaluating related reduction A discussion about economic environmental advantages FRs is provided, considering linked their installation emission restrictions. Relevant results obtained different routes, speed ranges rotor dimensions while investigating arrangement minimise both cost payback period.
