This module introduces you to the important aspects of pipes, fittings and valves used onboard ships. Learners will be familiarized with the pipelines that are used onboard together with the necessary fittings of valves that regulate fluid flow in the pipeline systems. The schematic pipeline diagrams in this module will also show the pumps that are used in creating pressures within the pipeline in transferring various fluids.

This module introduces you to the various types of pumps that are used onboard. You will discuss the basic principles of suction and delivery heads in a pumping system together with the working principles of reciprocating and rotary pumps. In this module, you will also study the components of various pipes and the state of the pumps, along with easy identification of faults in pumps and their maintenance scheme.

You must score 80% or more to pass this assessment.

This module introduces you to the system characteristics of fans and fan laws that are used onboard. You will discuss the basic principles of centrifugal fans and axial fans, the categorization and limitations of fan blade types, and their blade movement. In this module, you will also study the energy efficiency opportunities, along with where the system resistance curve and the fan curve intersect in determining the performance and efficiency of a fan.

This module introduces you to the various types of heat exchangers and compressors used on board. You will discuss the basic principles of heat exchange describing fluid flow arrangements and constructional features of tube shell and plate types of heat exchangers, together with principles of compression cycles. You will also study the heat exchanger maintenance and marine instruments used in the control-air installation.
