​Energy efficiency measures adopted onboard modern ships are developed since the early design stage through fixed procedures and feasibility criteria.

Some of these procedures were commonly used onboard the Italian Navy vessels, but newly-built and future ships have been designed to apply more advanced technologies in line with the degree of flexibility required for the new dual-use naval platforms.

Such measures mainly include:

    • underwater propeller cleaning, periodically performed by the ship's divers;
    • one shaft trailing mode with the propeller pitch set for low speed patrolling;
    • use of electric propulsion;
    • automated control of electric loads.
