Marine auxiliary machinery, such as pumps, fans and blowers, are essential equipment for all ships. This course introduces you to the various pumping systems using extensive pipeline layouts with control valves. We will delve deeply into the different classifications of pumps onboard and the materials used to make shipboard pumps, fans and blowers sustainable. Learn about maintenance procedures, regulatory requirements and repair procedures involving shipboard pumps. Materials used in pumping systems are diverse. We discuss this in detail and the differences in fans with blowers in a machine system. Although rotary pumps may not have the capability of lifting a fluid from a low position, they are used in widespread applications such as fuel heating, domestic water heating, lubricating oil cooling, charge air cooling and condenser cooling. In marine engineering, fans are designed to serve various needs using air under pressure. The many types and sizes of the blowers are available for the central air fans, even if it is mostly the reciprocating tandem type that is used. Gain an understanding of the basic principles and layout, including the air receivers, which will help operate the air pressure.

This course explains how pumps aid in carrying abrasive and corrosive fluids exposed to atmospheric corrosion along with general wear and tear. Learn how these pump aids can operate at extremely high temperatures. The course describes the regulatory requirement used in centrifugal and axial fan maintenance. You will determine how the classification of societies has specific requirements regarding ships' fan systems that follow the general survey criteria for the rest of the vessel. Furthermore, you will learn about the maintenance procedures and troubleshooting measures for pumps and mechanisms. Discover the basic maintenance procedures, systems, constructional features and principles of operation. This course discusses the reciprocating pump as a positive displacement pump where the movement of the piston displaces the fluid. Explore the effect of a constant volume of liquid drawn into the pump cylinder through the suction valve on the suction stroke. Gain knowledge about the discharge of fluids under positive pressure through the delivery valves on the discharge stroke. We will take you through the classification of reciprocating pumps based on their working principles.

If you are intrigued about how devices that produce a current of air by the movement of broad surfaces can be called a ‘fan’, this extensive course on marine auxiliary machinery is a must for you. Fans fall under a general category of turbomachinery and have a rotating impeller at least partially encased in a stationary housing. This course describes the similarity of fans and in many respects their resemblance to pumps: both are turbomachines that transfer energy to a flowing fluid. Distinguish between fans and pumps and understand the function of a fan and how it moves air or gas. Appreciate the role of fans in a ship and discuss how the purpose of all types of checks is to allow proper functioning. The course examines the various pump concepts, like the most common pump used to move large volumes of water and the centrifugal pump used in simple construction and operation. This course will be of significant interest to students, researchers, marine engineers and anyone seeking to learn about marine equipment and maintenance procedures.
