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.
