Retrofitting hull enhancements for ships is an established approach to reducing carbon emissions and improving energy efficiency in the maritime industry. This process involves modifications to the ship’s hull to minimise and reduce resistance and optimise hydrodynamic performance, leading to lower fuel consumption and emissions. 

Advanced technologies such as propellor polishing, hull cleaning, Propulsion Improving Devices (PID’s) and air lubrication enhancements can offer a feasible path to decarbonisation by enhancing operational efficiency. The design and integration challenges of retrofitting hull enhancements are important to take into account,  plus the operational challenges to maximise the benefits of the installed technology. 

Retrofitting hull enhancements can be a complex yet essential step towards a more sustainable maritime industry. It demands careful consideration of technical, compliance, and operational factors to ensure successful implementation to maximise the benefits of reduced emissions and improved efficiency.
