SmartShip aims to offer a multi-layer optimization in the fields of fuel consumption, energy efficiency and emissions control management, in full respect to the implementation of the requirements of maritime sector regulations and considering applications of circular economy concepts in the maritime as well. The project will deliver an ICT & IoT-enabled holistic cloud-based maritime performance & monitoring system, for the entire lifecycle of a ship, aimed to optimise energy efficiency, emissions reduction, and fuel consumption, whilst introducing circular economy concepts in the maritime field.
