Foreship published an infographic focusing on how to accomplish a 25% energy savings, coming from hull and propulsion, HVAC, thermal energy utilization, hotel and electrical and alternative energy resources.
As presented in the infographic above, Foreship suggests some ways according to which the shipping sector can achieve a 25% energy saving.
As such, the maritime industry can accomplish:
8% savings via hull and optimisation: Hull form and optimisation will contribute to the correct speed and conditions;
- Appendage optimization;
- Air resistance;
- Air lubrication;
- Propulsion system;
- Optimization of thruster tunnels;
- Energy Advisory.
5% savings via HVAC: Chiller plant and air conditioning optimisation;
- Absorption chillers;
- VFD driven AC chillers;
- LNG cold recovery to CW;
- Air Handling Unit technology;
- Optimized galley ventilation;
- Chilled beam in cabins;
- CFD simulation for air conditioning.
3% savings from thermal energy utilisation: Maximized energy utilization onboard with waste heat recovery technology;
- Two stage exhaust gas boilers;
- Steam turbine;
- Thermal energy storage;
- Sliding steam pressure;
- Common WHR circuit.
5% savings in hotel and electrical: Improve base processes onboard for higher efficiency;
- Fresh water production;
- Power plant configuration, variable speed main engines;
- High efficiency pumps and fans;
- Energy management.
5% savings from alternative energy resources: Alternative energy resources to improve efficiency and environment.
- Feasibility studies for Battery Energy Storage;
- Feasibility studies for Fuel cell technology and fuel alternatives.
