    Example Ocean Passage

    From Oceean Quay, Southampton

    To New York, via Nab Tower.

    ETD 1600 9thJanuary 2012

    Principles are the same regardless ofsize or type of craft

    Voyage Planning In all cases, the plan will cover from berth

    to berthand apply to anytypes of vessel.

    For your practical Navigation you

    will only do detailed plans of; Exit and/or entry

    Advantages of Voyage Planning

    Margins of safety are considered vertical (depth) & horizontal (distance)

    Critical sections of the voyage areidentified Important information will not be missed Navigation marks and systems identified

    Watchkeeping duties are planned to ensureadequate rest

    Contingency plans can be drawn up

    There are 4 stages in voyageplanning

    1. Appraisal: collecting information

    2. Planning: planning voyage from berth toberth

    3. Execution: update plan beforedeparture

    4. Monitoring: making sure ship keeps to theplan

    1. Appraisal Checklist

    Great Circle or Rhumbline routes

    TSS and shipping lanes, traffic, fishing vessels

    ETD,ETA and speed of advance (SOA) Meteorology Climate/weather

    Limitations of ship, eg loadline changes

    Limiting danger lines (LDL or no go lines) Time zones

    Availability of navaids

    Detailed planning

    Routes with alternatives, with LDL andcourses.

    Distances to run

    ETD,ETA planned noon and midnightpositions

    SOA and any changes

    Predicted currents

    Known meteorologiccal data (fog,ice etc)

  • 8/13/2019 Passage Plan 3

    Detailed brief before the passage

    Use the small scale chart(covers a largearea)

    Plus any large scale charts to explaincritical phases

    These may be ECDIS

    Appraisal (contd.)

    Correct charts are available and up to date

    Sailing Directions, Light Lists, etc. available

    Latest Notices to Mariners received Tides, currents, weather information

    Ships routeing and traffic volume expected

    Port and pilot information Any special requirements for the ship

    2. Planning

    On the basis of the appraisal, adetailed voyage plan is prepared

    from berth to berth (even when apilot is on board)

    drawn on the chart(s)

    written in a bridge notebook

  • 8/13/2019 Passage Plan 3

    14/18

    Planning (contd)

    On the chart [with summary in bridgenotebook] tracks and courses to steer, where to alter

    course/speed highlight danger areas wrecks, shallows, etc identify electronic aids to navigation that can be

    used Identify good position fixing objects, e.g.

    lights, transits, clearing bearings, radar/visual objects

    where the tide is critical, e.g height, or rate alternative contingency plans

  • 8/13/2019 Passage Plan 3

    15/18

    3. Execution

    When departure time is known,consider:

    ETA at critical points in the plan the weather forecast traffic conditions night or daylight passage

    i.e. does anything need to bechanged?

  • 8/13/2019 Passage Plan 3

    16/18

    4. Monitoring

    Monitor position along planned tracksby frequent fixing of position, incl.

    echo sounder Record key positions & alterations in

    the bridge logbook

    Check reliability of all navigationequipment at regular intervals

    17/18

    Note

    The extent to which a vessel can keep to theplanned track will depend on the type & speed ofthe vessel:

    A sailing vessel or slow power boat tends to benavigated towardsthe destination, as they aremuch affected by wind & tide and cannot keepexactly to the planned track

    A higher powered vessel is less affected bywind & tide and is therefore able to benavigated tothe destination closer to theplanned track
