Investigating the effects of maintenance and environmental conditions on the operational efficiency of ships by analysis on the real operational data

The maritime sector has recently been under pressure to reduce its fuel consumption due to the restriction on Greenhouse gas emissions and fuel prices. The new regulations of the International Maritime Organisation (IMO) regarding operational management and design limitations enter force in following years. Besides that, fuel consumption cost represents a major of total ship operation cost. Due to these, environmental performance and energy efficiency are top issues for ship operators and technical departments who are in pursue of cost reductions and greener operations. In this case, fouling management by hull and propeller cleaning and intelligent operations by considering environmental conditions may give ship operators to reach remarkable fuel saving. In this study, different 7 ships' noon data are examined in terms of fouling and environmental conditions such as sea state and sea direction. The Energy Efficiency Operation Indicator (EEOI) and main engine fuel consumption per nautical miles (T/NM) are considered as efficiency Key Performance Indicators (KPIs). This research's aim is to analyse of fuel consumption data before and after hull and propeller cleaning period and indicate any relevant way of these maintenances affects fuel consumption. Secondly, this research also aims to determine how ship speed is influenced by different sea state conditions and different wave & wind directions.
