Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria and include knowledge of: alterations, including: alterations of course reduction in speed effects of current, wind and restricted water on helm response features of a vessel that relate to its handling characteristics importance of navigating at reduced speed to avoid damage caused by own vessel bow wave and stern wave manoeuvres, including: application of constant-rate-of-turn techniques berthing and unberthing under various conditions of wind, tide and current with and without tugs choice of anchorage: anchoring with one or two anchors in limited anchorages and factors involved in determining the length of anchor cable to be used determining the manoeuvring and propulsion characteristics of common types of vessels, with special references to stopping distances and turning circles at various draughts and speeds dragging anchor and clearing fouled anchors dry-docking, both with and without damage handling vessel in rivers, estuaries and restricted waters with due regard to the effects of current, wind and restricted water on helm response importance of navigating at reduced speed to avoid damage caused by own vessel bow wave and stern wave interaction between passing vessel and own vessel and nearby banks managing and handling vessels in heavy weather, including assisting a vessel or aircraft in distress, towing operations, means of keeping unmanageable vessel out of trough of the sea, lessening drift and use of oil manoeuvres when approaching pilot stations and embarking and disembarking pilots with due regard to weather, tide, head reach and stopping distances manoeuvring in shallow water, including the reduction in under-keel clearance caused by squat, rolling and pitching methods of taking on board survivors from rescue boats and survival craft practical measures to be taken when navigating in or near ice or in conditions of ice accumulated on board precautions in manoeuvring to launch rescue boats or survival craft in bad weather procedures for and anchoring in deep and shallow water turning a vessel on a reciprocal track to rescue a person overboard using propulsion and manoeuvring systems, including various types of rudder vessel and tug interaction manoeuvres when towing or under tow manoeuvring and propulsion characteristics of common types of vessels means of keeping an unmanageable vessel out of trough of the sea, lessening drift and use of oil nature of emergencies, including: beaching cargo shift collision damage to the vessel disabled or partially disabled vessel fire grounding loss of steering gear, including rudder person overboard operational environment, including: bank effect conditions of loading marine park areas passing vessels shallow and restricted waters orders, including: communications with shore embarking or disembarking a pilot engine helm preparation for being towed or towing another vessel preparation for taking tug lines running mooring lines procedures for entering and leaving traffic separation zones reduction in under-keel clearance caused by squat, rolling and pitching situational awareness, including: berthing and unberthing with tugs choice of anchorage dry-docking effects of current, wind and restricted waters on helm response head reach in or near ice or ice accumulation on board launching lifeboats or survival craft load conditions own vessel bow wave and stern wave pilot boarding grounds requirements of the manoeuvre rivers, estuaries and restricted waters safe water shallow water stopping distances and turning circles taking onboard survivors from lifeboats or survival craft tide traffic operation schemes weather conditions use of propulsion and manoeuvring systems use of, and manoeuvring in or near, traffic separation schemes (TSS) and in vessel traffic service (VTS) areas vessel and tug interaction vessel handling characteristics, including: effects of single or twin screw effects when moving astern stopping ability use of controllable pitch propeller (CPP) vessel resources, including: bow and stern thrusters communications equipment engine control systems helm and rate of turn indicators personnel WHS/OHS requirements and work practices. |
