Achieving energy efficient ship operations under third party management: How do ship management models influence energy efficiency? [PDF]

Research in Transportation Business & Management, 2015
Profitable energy saving measures are often not fully implemented in shipping, causing energy efficiency gaps. The paper identifies energy efficiency gaps in ship operations, and explores their causes. Lack of information on energy efficiency, lack of energy training at sea and onshore and lack of time to produce and provide reliable energy efficiency ...
