Elements and Performance Criteria

  1. Provide commands to bridge and engine room to effect manoeuvres
  2. Order adjustments to vessel course and speed to maintain safe navigation
  3. Command vessel during emergencies
  4. Work with pilot to ensure safe passage to berth or anchorage

Range Statement

Range is restricted to essential operating conditions and any other variables essential to the work environment.

Situational awareness includes:

berthing and unberthing with tugs

choice of anchorage

dry-docking

effects of current, wind and restricted waters on helm response

headreach

in or near ice or ice accumulation on board

interaction between passing vessels and between own vessel and nearby banks

launching life boats 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 on board survivors from life boats or survival craft

tide

traffic operation schemes

vessel and tug interaction

vessel traffic service (VTS) areas

weather conditions

Manoeuvres include:

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, 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, headreach 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

turning a vessel on a reciprocal track to rescue a person overboard

Performance Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements, performance criteria and range of conditions on at least one occasion and include:

applying constant-rate-of-turn techniques

applying relevant work health and safety (WHS)/occupational health and safety (OHS) requirements and work practices

basing 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 anchor

berthing and unberthing under various conditions of wind, tide and current with and without tugs

clearing fouled anchors

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

handling vessels in rivers, estuaries and restricted waters having due regard to the effects of current, wind and restricted water on helm response

issuing helm and engine orders

making 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 weather

managing 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 oil
