Search Operations
3
Search Operations
  • Require meticulous habits and thoroughness to
    perform effective searching, spotting and
    accurate manoeuvring through search patterns

4
Search Operations
  • A search operation may involve numerous
    resources, and JRCC will appoint an On Scene
    Commander
  • This is dependent upon the capabilities of the
    resources
  • The JRCC may appoint your vessel as Co-ordinator
    Surface Search

5
Search Operations
  • There is no time limit on a search so be careful
    and methodical
  • Make sure you are properly prepared to be out on
    the water for a long time, and are fully equipped
  • Stop and talk to other vessels that are met in
    the area

6
Search Operations
  • Keeping a safe lookout under the collision rules,
    applies to search operations although the two
    operations are entirely separate
  • This means using sight, hearing and all other
    appropriate means to assist in the search

Searching
10
Search Operations
  • With overdue vessels, JRCC may request
  • 1. contacting with marina manager or wharfingers
    to check whether boat has been seen there
  • 2. check every vessel carefully for license
    number, description and name
  • 3. check the parking lot of their marina for
    their vehicle
  • 4. ask other people out on the floats

11
Search Objects
12
Search Objects
  • The persons or objects that are being searched
    for may have been given by JRCC
  • However the searchers should be looking for
    anything that could give a clue of the incident
  • Anything of note should be reported to JRCC

13
Search Objects
  • This could include
  • Persons in the water
  • Persons on the shore, or indication that people
    have been recently there, e.g. wet drag marks up
    a dry rock, discarded clothing
  • Boats, canoes, sail boards, either floating
    normally, water logged or floating upside down

14
Search Objects
  • EPIRBs
  • Distress signals
  • Survival craft, liferafts, lifebuoys, lifejackets
  • Garbage on the water which may be from a boat
  • Flotsam and jetsam
  • Oil slick on the water

Distress Signals
  • All are listed in Annex IV of the collision
    regulations
  • Recognize the signs
  • Know what to do
  • Be familiar with your own signaling devices

27
Search Patterns
28
Search Pattern Definitions
  • Commence Search Point - where to start first leg
    of search
  • Search Leg - one of successive tracks run by
    search vessel
  • Cross Leg - tracks that connect search legs
  • Track Space - distance between adjacent tracks
  • Major Axis - longest axis of rectangular search
    area

29
Search Pattern Definitions
  • Minor Axis - short side of a rectangular search
    area
  • Creep Direction - direction of advance of search
    vessel within search area
  • Beam Sighting Distance - lateral distance
    searched on both side of search vessel (1/2)
    track spacing and normally less than maximum
    detection range

30
Track Spacing
  • This is dependent upon the detection range of the
    object that is being searched for, with smaller
    objects requiring a smaller track spacing
  • It is a function of Sweep Width and the desired
    coverage factor

31
Sweep Width
  • This is dependent upon the detection range of the
    object that is being searched for, with smaller
    objects requiring a smaller track spacing

32
Sweep Width
  • Sweep width is governed by
  • 1. Size and type of the search object
  • 2. Weather and sea conditions, e.g seas, spray
  • 3. Flotsam
  • 4. Type of search craft and speed
  • 5. Search altitude for aircraft
  • 6. Search crew fatigue

33
Course and Leg Identifier
  • For Expanding Square Pattern Sector Pattern
    Searches.
  • This tool is a must have for anyone else who
    might have to run a search pattern. The Course
    Leg Identifier quickly calculates the heading and
    run time for each leg of either an expanding
    square pattern or sector pattern search, giving
    you more time to focus on the search.

Search Aids

Search Aids
43
Search Aids
  • Use primarily your eyes and ears for searching
  • Raise your height of eye if possible to increase
    the range you can see
  • Only use binoculars if you see something that is
    not clear to normal vision
  • Do not smoke as it adversely affects night vision

44
Search Aids
  • The Datum Marker Buoy is used to assess the
    actual movement of bodies in the water.
  • When deployed on arrival at the scene, its
    movement can be tracked and passed to JRCC for
    live information on any set and drift being
    experienced to assist with the accuracy of the
    search

45
Search Aids
46
Search Aids
  • White illumination flares can be used to
    illuminate the scene
  • If in radio contact with a distress in an unknown
    location, they can tell the rescue vessel if the
    flare can be seen, if no other conspicuous
    landmark or navigation mark can be seen

47
Search Aids
48
Search Resources
  • These may include
  • 1. Canadian Coast Guard vessels and hovercraft
  • 2. Boats
  • 3. Ships
  • 4. Naval ships
  • 5. Police vessels

49
Search Resources
  • 6. Fishing vessels
  • 7. Pleasure craft
  • 8. Harbour Authority craft

50
Search Resources
  • Other Resources that may be involved
  • Land based rescue volunteers
  • Police
  • DND Cormorant helicopters and aircraft
