Many shipping companies struggle to realise significant savings through implementing energy efficiency measures. While industry leaders claim to achieve savings of more than 30%, most only realise minor savings of 1 to 3%.
Successful companies have ensured a few success factors.
- A holistic approach to defining energy saving measures. A detailed cost-benefit review ensures that those measures are selected which best fit to the company specific operational profile and business model. The review covers all areas of improvement:
- The voyage: Optimising schedules and ensuring effective voyage execution and speed management
- The fleet: Ensuring effective fleet composition for the defined network set-up, ensuring transport system optimisation
- The organisation and management: Establishing an effective organisation that ensures ownership for energy management activities, and allows for performance and change management
- The vessel: Optimising the hull and propeller condition, draft, trim, autopilot and rudder settings
- The main and aux engines: Efficient performance of the main and auxiliary engines as well as generators
- The Consumers: Optimised consumer usage in all operational modes
- A dedicated team or person steers and coordinates all the energy management related topics:
- Coordination of all the energy management activities
- Monitoring and tracking of the measures’ implementation and impact
- Regular review of benefits and costs of fuel saving measures
- Support through change management activities, training and communication
- Energy management programs are supported through a performance management that provides the required transparency at an operational, managerial and technical level
Finally, it is a matter for top management to ensure that savings are generated. Only their commitment and interest ensures that the change in behaviour will take place.
