Maritime Infographic: Roadmap to Net-Zero GHG

(www.MaritimeCyprus.com) To achieve the International Maritime Organization's (IMO) goal of decarbonizing shipping by 2050, merchant ship owners and operators must adopt a range of measures to significantly reduce greenhouse gas (GHG) emissions. Foreship's Roadmap to Net-Zero GHG outlines various strategies, from technical modifications to operational changes, that can collectively drive the shipping industry towards a more sustainable future. The following measures represent key actions that can be implemented to optimize energy efficiency, reduce fuel consumption, and lower emissions across the global fleet.

Decarbonisation measures

1. Wind-assisted propulsion: Utilizes sails or rotors to harness wind power, reducing fuel consumption and emissions.
2. Limiting air resistance: Reduces aerodynamic drag on the vessel, improving fuel efficiency.
3. Hull shape optimization: Streamlines the hull design to minimize water resistance, leading to lower energy consumption.
4. Voyage optimization: Plans the most efficient routes and speeds to minimize fuel use and emissions.
5. Use of shore power in port: Connects to electrical power at the dock, allowing engines to shut down and reduce emissions while at port.
6. Hull air lubrication system: Creates a layer of air bubbles along the hull to reduce friction between the ship and water, improving fuel efficiency.
7. Battery energy storage systems: Stores energy for use during peak demand or low-speed operations, reducing reliance on fossil fuels.
8. Use of alternative fuels: Switches to cleaner fuels like LNG, biofuels, or hydrogen to reduce greenhouse gas emissions.
9. Engine optimization: Enhances engine performance for maximum efficiency, lowering fuel consumption and emissions.
10. Hull appendix optimization: Adds devices like fins or bulbs to the hull to reduce drag and improve hydrodynamic efficiency.
11. Propulsion improvement devices: Implements enhancements like ducts or fins near the propeller to improve thrust and reduce fuel usage.
12. Shaft generator use: Uses the ship's shaft to generate electricity, reducing the need for auxiliary engines and saving fuel.
13. Waste heat recovery systems: Captures and reuses waste heat from the engine, improving overall energy efficiency.
14. Lighting system optimization: Uses energy-efficient lighting and control systems to reduce the ship's electrical load.
15. Propeller refitting: Upgrades or modifies the propeller design to enhance efficiency and reduce fuel consumption.
