Description

Displacement and hydrostatic curves is a free online course that begins by introducing you to the key feature that makes up a successful boat design. This course will introduce you to the concepts and definition of buoyancy, together with the principle of floatation. This course will teach you about vertical and longitudinal distance relating to the draft of the ship, along with the law of floatation. You will learn about the concepts and characteristics of displacement tonnage. The differences, as well as the relationship between the displacement and mean draught of a ship will be covered in this course. This course will also introduce you to displacement tables, deadweight scales, and draught curves which are used to relay information pertaining to displacement at different draught levels. This course will teach you about the two constituents of displacement which include; light and load-displacement. The concepts and functions of deadweight will also be covered in this course. You will also learn about the relationship between the waterplane area and tons per inch, along with the effect of tons per inch on the ship’s draft.

This course then explains the concepts, functions, and calculations of trim and moment to change the trim by 1 inch. You will learn about the functions of fresh watermarks for the ship. This course will teach you about the calculation, along with the relationship between freshwater allowance, displacement of the ship in saltwater, and tonnes per centimetre. You will also learn about how a draft increase from saltwater to dock water and vice versa. The change of draft when calculated between saltwater and dock water will also be covered in this course. This course also explains the effect of a constant draft on the displacement of the ship. This course will teach you about the calculation of freshwater allowance, dock water allowance, and tons per inch in various densities. You will also learn about the content, readings, and importance of hydrostatic curves. The functions of hydrostatic tables will also be covered in this course. This course will then teach you about the differences between the hydrostatic draft and the amidships draft. This course also explains the concept and functions of the hydrostatic draft.

Furthermore, this course will help you get familiar with the position and working principle of the centre of floatation. You will learn about the positive and negative correction to apply the mean draft to obtain a hydrostatic draft. This course will also teach you about the calculation of BM and KM. You will also be familiar with the calculation of BM in rectangular waterplanes, box-shaped vessels and triangular-shaped vessels. The principles of transverse statical stability will also be covered in this course. You will also be familiar with the stable, neutral and unstable equilibria. This course will also teach you about the transverse metacentre. You will also learn about the moments of statical stability at small and large angles of the heel. This course will give you a better understanding of the angle of loll, as well as the correction of the angle of loll. The free surface effect and effect of slack tanks will also be covered in this course. This free online course will be of great interest to students, researchers, and anyone with an interest in propulsion systems and load-lines.
