Ship Energy Efficiency as Competitiveness Factor for Revamping or Scrapping Decisions
Abstract
Many vessels have been dismantled based on energy efficiency considerations, becoming an environmental problem and contributing to the non-sustainability of materials. Revamping existing ships in view of improving their operating costs may be seen as a sustainable approach.
The article focuses on the use of a specific procedure to determine and evaluate the ship energy improving actions and their technical and economic evaluation, therefore allowing the support of the revamping or scrapping decision.
This article uses a number of existing ships as examples.
