Enhancing A Reliable Ship Performance Evaluation in Dynamic Maneuvering Conditions – A Gap Analysis

Abstract

Ship and propeller interaction greatly affect ship maneuvering performance and behavior. In steady ahead operation, the interaction properties remain unchanged due to steady ship-propeller operations. In dynamic operations, such as stopping, the properties vary considerably based on the ship and propeller speed combinations. Past researches and practices use a simplistic assumption of single and constant value resembling steady ahead operation due to the lack of knowledge and data on the properties. Up to very recently, researchers in the field and related areas refer to the one and only work from more than five decades ago. The current research presents an insight to disclose the properties features, efforts, and progressions made in the field to the extent of challenges bottlenecking the development. The work broadens the analysis of the implication and inadequacy of the current circumstance toward appropriateness, accuracy, and validity of the research and related studies in the field.?
