Elements and Performance Criteria
Range Statement
Performance Evidence
Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria on at least one occasion and include:applying constant-rate-of-turn techniquesapplying relevant work health and safety (WHS)/occupational health and safety (OHS) requirements and work practicesbasing all decisions concerning berthing and anchoring on a proper assessment of vessel manoeuvring and engine characteristics and the forces to be expected while berthed alongside or lying at anchorberthing and unberthing under various conditions of wind, tide and current with and without tugsdetermining the manoeuvring and propulsion characteristics of common types of vessels, with special references to stopping distances and turning circles at various draughts and speedshandling vessels in rivers, estuaries and restricted waters having due regard to the effects of current, wind and restricted water on helm responseissuing helm and engine ordersmaintaining situation awarenessmaking a full assessment of possible effects of shallow and restricted waters, ice, banks, tidal conditions, passing vessels and own vessel bow and stern wave while under way so that the vessel can be safely manoeuvred under various conditions of loading and weathermanaging and handling vessels in heavy weather, including assisting a vessel or aircraft in distress, towing operations, keeping unmanageable vessel out of trough of the sea, lessening drift and using oilmanoeuvring in shallow water, including the reduction in under-keel clearance caused by squat, rolling and pitchingusing propulsion and manoeuvring systemsusing remote controls of propulsion plant and auxiliary machinery. |
