Methodology for optimising the hull shape of a vessel with restricted draft

Abstract

Increasing transport volumes on Europe's inland waterways is a major reason for improving the quality and reliability of internationally important waterways. Continued navigation restrictions due to restricted draft (draught) led to the search for new design solutions. Such solutions enable navigation even under critical navigation conditions. Restricted draft is one of the most important limitations that hinder navigation, especially in the summer. The main objective of the construction of an inland vessel is to obtain a shape that will achieve optimum performance with as little resistance as possible. A shape that will be able to navigate at a limited depth. Presently, there is no clearly defined methodology as a procedure for optimising the hull. When solving theoretical problems of shipbuilding character and ship calculations, it is necessary to consider the basic theory of the ship with special regard to the latest methodological procedures of related scientific disciplines. This paper presents a methodology that considers all the basic aspects of optimisation tasks in ship design and construction.

Concept and Performance Analysis of Propulsion Units Intended for Distributed Ship Systems

“…The research was conducted on numerical methods CFD, which allowed the calculation and comparison of the performance characteristics of propellers through direct recording of their hydrodynamic quantities during the analysis. These methods are described in detail in pilot studies [18,21]. The creation of a spatial CFD domain for vessel navigation analysis usually starts in a 3D modeling program.…”

“…Research in the field of improving the conditions of navigation on inland vessels is focused primarily on hull shape optimization and traditional stern propulsors. A detailed description of the numerical calculation methodology is summarized in several studies [17,18]. The installation of distributed propulsion (on the sides of the hull) on inland waterway vessels represents a new way of addressing the issue of navigability of watercourses for commercial navigation due to low navigation level, which is a major restriction for smooth inland waterway transport [19,20].…”

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

“…Formerly, Sutulo and Soares (2011) who reviewed various selected topics related to mathematical models mainly for simulation of ship maneuvering purposes acknowledged that not much data on the properties were available aside from the work hence encouraging the collection of new data. Recently, both Illes et al (2021) and Illes et al (2020) also listed the work despite unclear contributions to the studies.…”

“…However, knowledge and data on the hull-propeller interaction properties in various maneuvering conditions are very limited (Ye et al, 2012;Sutulo and Soares, 2011;Artyszuk, 2003;Harvald, 1976). The work of Harvald (1977Harvald ( , 1967 as the pioneer (Artyszuk, 2003) since more than a half-century ago is still referred to by various researchers in the field and related areas up to now (Illes et al, 2021(Illes et al, , 2020Sunarsih, 2018;Trodden and Haroutunian, 2018;Sutulo and Soares, 2011). Only recently, Sunarsih (2018) was recorded to execute similar research and took advantage of the properties developed to evaluate ship-stopping ability based on the Standards framework.…”
