This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
The person credited with this unit standard is able to identify and explain ship machinery and systems. They are also able to describe the construction and operation of diesel, refrigeration, engineering pumping, steering and electrical systems of a vessel. The person will also be able to describe problems and corrective action needed to rectify the problem related to any of the ship's systems.

The qualifying learner is capable of:
  • Identifying ship's machinery and systems.
  • Explaining the basic construction and operation of the ship's diesel engines.
  • Explaining the basic construction and operation of the ship's refrigeration system.
  • Explaining the basic construction and operation of the ship's main engineering pumping systems.
  • Explaining the basic construction and operation of the ship's steering gear.
  • Explaining the basic construction and operation of the ship's electrical systems.

    PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
