  2. Outline • Background • Energy Efficient Fleet Operations • Optimum Weather Routing • Weather Routing and Monitoring • Improvement of Weather Routing by Broadband • Next Challenge

  3. Background

  4. Save bunker activities in shipping company • According to increased cost of bunker, shipping companies have applied operational and technical measures for fuel savings • Slow steaming • Weather routing • Propeller cleaning • Energy saving devices Cost benefit and emission reduction by slow steaming e.g. 8,000 TEU container Slow steaming - 16 % - 42 %

  5. Performance monitoring- compare total fuel consumption • Same ship size and same voyage – but total amounts of fuel consumption largely differ More than 30 % difference

  6. SEEMP - PDCA management for energy efficiency • SEEMP (Ship Energy Efficiency Management Plan) • MEPC 62 adopted revisions of MARPOL Annex VI introducing EEDI and SEEMP • Entry into force date: 1 January 2013 • Operational measures • slow steaming • weather routing • hull and propeller maintenance • …. Plan Do Check Act Continuous monitoring & improvement Importance of Energy Efficient Operation is increasing

  7. Energy Efficient Fleet Operations

  8. Best balance of safety, economy and environment No cargo and ship damage Keep schedule Maximize charter base (minimize cost) Minimize emissions Fleet operation Snapshot from NYK e-Missions’ NYK fleet: about 800 vessels now Multi-objective optimization

  9. Management for energy efficient operation- Needs all related parties participation Plan – routing Do - navigation PDCA cycle for improvement Act – corrective action Check – monitoring To encourage all participants efforts for energy efficient operation by sharing information, good communication and right scheme

  11. Introduction of Onboard Broadband on NYK Fleet - Improve Infrastructure Reducing CO2 emissions by introducing onboard broadband

  12. IBIS (Innovative Bunker and Idle-time Saving) PJ - Effective Utilization of Broadband Sharing Information including weather, sea forecasts, sea-current, and ship-operation data between land and ships in real time.

  13. Optimum Weather Routing

  14. Optimum Weather Routing • Role of weather routing • (past) Avoiding severe weather • (now) Optimum weather routing Best balance of • Safety • Schedule keep • Economy • Environment • Necessary technology for optimum weather routing • Ship performance model • RPM – speed – fuel consumption • Ship motion and performance in severe weather Way points Routes and weather

  16. Weather Routing and Monitoring

  17. Integration of Weather Routing with Monitoring Performance Monitoring（CHECK） Weather Routing（PLAN） • Actual voyage • + actual weather • + ship performance data • + ship motion data • Voyage plan • + weather forecast • + ship performance model • + ship motion model Feedback Ship model and weather forecast inherently include errors. Feedback loop with monitoring can make this system work better.
