A Data Replenishment Method for Self Regulating Sail-Assisted Ships Considering Big Data
The concept of intelligent sail-assisted ships based on big data comes to people's mind gradually. Data loss and distortion cannot be avoided during data collecting and preprocessing process. In this paper, a data replenishment method based on computational fluid dynamics (CFD) method is proposed and simulation cases are done to explain the method
Energy Efficiency Design Index (EEDI) for New Ships and Coping Strategies Analysis
EEDI is an indicator of ship's energy efficiency level,which is put forward by IMO and demonstrates ship's energy efficiency with the ratio of CO2 emission to freight capacity.In the paper,EEDI and ship types,to which mandatory EEDI will be applied,are introduced.Deficiencies of the EEDI calculation formula are investigated,and some coping strategies are presented from both theoretical research and technical approach.
Ground Fault Protection for Electric Utility Generating Station Medium Voltage Auxiliary Power Systems
Most generating station designs have medium voltage auxiliary power systems with low resistance grounded neutrals.1 In order to provide even higher reliability, the auxiliary power distribution system configurations supply increasingly redundant process equipment.
