TECHNICAL AND ECONOMIC EVALUATION OF IMPLEMENTING SHIP ENERGY EFFICIENCY MANAGEMENT PLAN (SEEMP) ON STEAM PROPULSION LNG CARRIER

Abstract

Ship Energy Efficiency Management Plan (SEEMP) is a simple approach for monitoring ship and fleet efficiency performances from time to time as well as for emission monitoring and reduction as mentioned as in the rule and regulation. SEEMP also provides some options to be considered to optimize ships efficiency to reduce emission. SEEMP consists of four stages. The first stage is the planning stage, followed by implementation, monitoring and self-evaluation, and finally improvement stage. In the planning stage, any ship-specific measures that can be implemented on board the ship to improve the ship efficiency as well as to reduce emission are determined. After the ship-specific measures are implemented, they will be monitored in the third stage by using Energy Efficiency Operational Indicator (EEOI). In the final stage, an overall analysis from the data collected in the monitoring stage are analyzed in order to deepen the understanding on the overall characteristics of the ship’s operation, such as which type of measures that can or cannot function effectively and lastly to improve the SEEMP for the next cycle. This project focuses on how to implement the SEEMP on a steam propulsion LNG carrier. Technical and economic evaluations of SEEMP implementation on steam propulsion LNG carrier have been carried out for weather routing optimization and asymmetry pre-swirl stator.
