ENERGY EFFICIENCY MANAGEMENT SYSTEM APPLICATION MEASURED DATA ANALYSIS ON CONTAINER SHIP

摘要

Recent global recession has been prolonged as positioning ship owners to unfavourable business environment for several years. Most of shipping companies are currently trying to ascertain their energy efficiency levels and to find energy saving opportunities to survive in this hard time. For this reason, the ship energy management system is considered as a monitoring and evaluation tool for the cost reduction simultaneously satisfying SEEMP regulation. However, the accurate vessel performance evaluation is very difficult in actual seagoing conditions in reality. Vessel efficiency changes up to 30% depending on the weather condition, ship motion, engine status, etc. In this paper, more comprehensive vessel operational optimization and performance evaluation are executed for container vessel. The container vessel is equipped with trim, route, speed optimization tools with state-of-art technologies. In addition, main equipment performance is evaluated, and weather & non weather effects are analyzed based on ISO correction method. The reasonable accuracy of vessel performance prediction is verified for the voyage from Busan in South Korea to Prince Rupert in Canada. Finally, energy saving potentials are discussed for each optimization techniques.
