Description

Propulsion systems and load lines is a free online course that begins by introducing you to the definition and elements of a propulsion system which include; propellers, drive shafts, clutches, and steering gear. This course will introduce you to the division of tug steering and propulsion systems which are; power source, power transfer and control system, along with thrust creation and directional control mechanism. This course will teach you about the characteristics of tugs and the operations of the tug’s horsepower. You will learn about the application of high-speed diesel, as well as the use of direct drive engines in deep-sea merchant marine vessels. The operations of the main propulsion slow-speed diesel engine, along with the components of a transmission system will be covered in this course. This course will also introduce you to the components of the stern tube, and the constant airflow type of stern tubes. This course will teach you about the purpose of the hydrodynamic drivers and the two types of hydrodynamic drivers. This course will help you identify the driver rotating around a horizontal axis (propellers), and which driver rotates around a vertical axis (Voith-Schneider cycloidal).

This course then explains the features, operations, working principles and designs of propellers. You will learn about the historical background, structure and functions of propulsion nozzles, as well as the steerable nozzle type. This course will teach you about the functions and constructional features of rudders some of which include; rudder stock, rudder post, pintle, rudder carrier and gudgeons. You will also learn about the balanced, unbalanced and semi-balanced rudders, along with important factors to consider when inspecting a rudder during drydock. The classification and characteristics of propeller blades from 3, 4 and 5 blade propellers will also be covered in this course. This course will also teach you about the classification of blades based on the solid fixed-pitch and constructional-pitch propellers. You will also learn about the operations of the right-handed and left-handed propellers. This course also explains propeller terms and the formulas for propeller pitch, propeller slip, propeller efficiency, and pitch ratio. The formulas for the pitch of propeller by measurement in drydock, disc area, blade area ratio, wake and the true slip will be covered in this course. This course will then teach you about the construction and operations of a bow thruster, along with the process of pitch control by thruster blades.

Furthermore, this course will help you get familiar with the functions, mechanisms and working principles of the Voith-Schneider propulsion system. You will learn about the controls in the Voith-Schneider tractor tugs. This course will also teach you about operations and mechanisms of the Azimuthing propulsion drives and its functions in stern-drive tugs. The salient features of the Articles of the Consolidated Load Line convention of 2018 will also be covered in this course. You will also be familiar with the purpose of the ship’s load line, the deck line, as well as freeboard and buoyancy. The course will teach you about margin line, forward and aft perpendicular, as well as the sub-divisional load line. The factor of sub-division, sheer and bow height will also be covered in this course. You will also be familiar with the characteristics and differences between type a and type b ships, as well as the concept of a ship’s tonnage. This free online course will be of great interest to students, researchers, and anyone with an interest in propulsion systems and load-lines.
