Assigned Department Objectives
Teaching Method
Outline:
The auxiliary devices to operate a ship are generic names of the larger parts of the machine other than the propulsion engine, main boiler and electrical equipment. Students will be able to properly understand what equipment they will first be in charge of as a member of the ship's crew. Students will learn about the operating principles, features and comparisons of the refrigerating cycle and various pumps.
Style:
Lectures and exercises
Notice:
Students whose evaluations are less than 60 points for the lecture content as a course subject required for training institutions based on the Act on Ships' Officers may take a make-up exam upon request. Students whose acquisition of units is acknowledged as a result of the make-up test will receive a score of 60 points.
