Introduction to ship stability and Simpson’s rules is an online course that begins by introducing you to the history of adaptive and variant designs in ships. This course will introduce you to the contributions of computational fluid dynamics along with ship model testing in the improvement of reliable and accurate ship designs today. This course will teach you about ship stability issues due to external forces that change the state of equilibrium and endanger the vessel. You will learn about the principal dimensions of a vessel used for performing basic calculations. You will learn about the importance of noting a ship’s length (L), breadth (B) and draught (d). The concepts and calculation of density and relative density will also be covered in this course. This course will also introduce you to the definition, functions and calculation of the Wetted Surface Area (WSA). This course will teach you about the three formulas commonly used in finding the approximate values of WSA based on ship dimensions and draught. You will learn about the relevance of the Haslar formula, Taylor’s formula, and Denny’s formula. You will learn about the relationship between displacement and a wetted surface area of two similar vessels.
This course then explains the principles, calculations, and practical applications of hydrostatic pressure. You will learn about the concepts of load on an immersed plane, as well as how to find a load on an immersed vertical and horizontal plane. This course will teach you about the four coefficients of importance needed to understand the basics of ship stability, along with their formulas. You will learn how to identify the block, midship, waterplane, and prismatic coefficients. The calculation and effect of tons per inch on the ship’s draft will also be covered in this course. You will also learn about the plotting and characteristics of the Bonjean curves. This course also explains how to draw predicted water lines and read drafts showing where the Bonjean curves are to be entered. The body, half-breadth, and sheer plan, along with the lines to which they are projected will also be covered in this course. This course will then teach you about stations and the types of stations which include; forward perpendicular, aft perpendicular, and midship stations. You will also learn about the waterlines, sectional lines, centrelines which are points of intersection formed when each plane intersects with the ship’s hull.
Furthermore, this course will help you get familiar with the numerical calculations for the waterplane area, sectional area, and submerged volume. You will learn about the brief history and concepts of Simpson’s rules. This course will also teach you about the characteristics, applications and equations of Simpson’s first, second and third rules. The longitudinal and vertical centres of buoyancy, as well as general hydrostatics particulars and curves, will also be covered in this course. This course will teach you about the calculations for the moment of area, the moment of inertia, and the moment of volume. You will also learn about semi-ordinates, appendages, and common interval. The calculation of displacement including and excluding tons per inch will also be covered in this course. You will also become familiar with the formula for finding waterplane area using Simpson’s three rules, as well as the trapezoidal rule. This free online course will be of great interest to students, researchers, and anyone with an interest in the application of Simpson’s rules in ship stability.
