PURPOSE OF THE UNIT STANDARD 
This unit standard is intended for learners within the Maritime Sector who work/wish to work as an officer on the bridge of a ship. This Unit Standard meets the needs of the sub-field and of the society by providing competent maritime officers who by ensuring the watertight integrity of a ship, contribute to a safer environment on the ship and at sea. The learner successfully completing this Unit Standard will gain essential knowledge and practical skills needed to monitor and maintain the watertight integrity of a ship.

The competencies achieved by the learner in this Unit Standard will, in the case of the Merchant Navy and the Fishing Industry, contribute to the economic upliftment of the country, and in the case of the South African Navy, contribute the preservation of human life and the defence of South African warships, territorial waters and/or area of responsibility, thus providing a safer and secure society for South African citizens.

Learners credited with this unit standard will be able to:
  • Demonstrate an understanding of general arrangements of common large and small ship types.
  • Demonstrate an understanding of the fundamental concepts of ship stresses.
  • Demonstrate an understanding of the purpose of load lines.
  • Explain how the structure and attachments of hull fittings are constructed. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    It is assumed that the learner has the following knowledge and skills:
  • Communication at NQF Level 4. 

  • UNIT STANDARD RANGE

    ASSESSMENT CRITERION 6 
    Typical buoyancy curves are drawn to illustrate forces on a ship's structure for a ship in different situations. 
    ASSESSMENT CRITERION RANGE 
    Situations include but are not limited to ships in still water, with a wave crest amidships and with a wave trough amidships.
     

    SPECIFIC OUTCOME 3 
    Demonstrate an understanding of the purpose of load lines. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1

    ASSESSMENT CRITERION RANGE 
    Marking include Plimsoll marks, Summer draught, deck line, summer freeboard, loadline zones, winter and tropic freeboards, Winter North Atlantic, fresh water allowance and Timber Load Lines.
     

    ASSESSMENT CRITERION 2 
    An explanation is given of the relationship between buoyancy and displacement with reference to implications for watertight integrity of the ship. 

    ASSESSMENT CRITERION 3 
    An explanation is given of the relationship between reserve buoyancy and freeboard with reference to implications for watertight integrity of the ship. 

    ASSESSMENT CRITERION 4 
    The applicable load line is determined by assessing the ship's maximum load of deadweight. 

    ASSESSMENT CRITERION 5 
    An explanation is given in terms of the checking of a freebord to determine that it is within its permitted limits of loading. 

    ASSESSMENT CRITERION 6 
    An explanation is given of the positioning of the draught marks of a ship with reference to implications for watertight integrity of the ship. 

    SPECIFIC OUTCOME 4 
    Explain how the structure and attachments of hull fittings are constructed.

    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.
