Standard
• Coordinate a surface search.
• Brief other resources on search plan and
allocate areas.
• Command multiple vessel search patterns.
• Monitor and log progress, and provide
SITREPs.
• Understand limitations on own vessel.
• Understand critical information.

Introduction
CANADIAN COAST GUARD AUXILIARY - PACIFIC
Introduction
• Joint Rescue Coordination Centre will
designate a surface vessel as On Scene
Coordinator for surface activities.
• On Scene Coordinators will be designated
from SAR units or military, naval or civil
vessels with SAR capability.
CANADIAN COAST GUARD AUXILIARY - PACIFIC
Introduction
• When deciding how much responsibility
JRCC delegates to the OSC, they will
consider communications and personnel
capabilities of the SAR units involved.
• Maximum number of SAR units under one
OSC will be 5.

Duties of the OSC
CANADIAN COAST GUARD AUXILIARY - PACIFIC
Duties of the OSC
• Coordinate operations of all SAR resources
on-scene.
• Receive the SAR plan from JRCC.
• Modify the plan as necessary, advising JRCC
of changes and reasons.
• Coordinate communications.
• Monitor performance and safety of other SAR
units.
CANADIAN COAST GUARD AUXILIARY - PACIFIC
Duties of the OSC
• Make SITREPs to JRCC at intervals.
• Maintain a detailed record of the operation,
including times of arrival and departure of
SAR units, areas searched, track spacing
used, sightings and leads reported, actions
taken, and results obtained.
• Advise JRCC of SAR units no longer
required.
CANADIAN COAST GUARD AUXILIARY - PACIFIC
Duties of the OSC
• Advise numbers and names of survivors to
JRCC.
• Advise JRCC of all SAR units with survivors
onboard.
• Request additional resources where required
(multiple survivors, injured survivors, etc)

Briefing Other Coxswains
CANADIAN COAST GUARD AUXILIARY - PACIFIC
Briefing Other Coxswains
• Emphasise safety of rescuers and distressed
persons.
• Emphasise team work, error checking.
• Designate communications channel and radio
procedures.
• Define search objects and area.
• Define SITREPs to OSC.
• Define track spacing and speed.
CANADIAN COAST GUARD AUXILIARY - PACIFIC
Briefing Other Coxswains
• Follow standard procedures.
• Encourage input from other resources where
difficulties are experienced and where plan
may need amending.
• Define search speed which all resources can
maintain.

Communications
CANADIAN COAST GUARD AUXILIARY - PACIFIC
Communications
• All communications must use proper
procedures.
• Frequencies will probably be decided by
JRCC.
• A primary and secondary frequency will be
assigned. E.g. 04A Primary 83A Secondary.
• SITREPs to be provided at required intervals.
CANADIAN COAST GUARD AUXILIARY - PACIFIC
Communications
• SITREPs to JRCC to consist of:
1. Identification of the incident if needed.
2. Initially a description of the incident, on-scene
weather, and any amplifying information.
3. Any action taken / completed since the last
SITREP, and any results.
4. Where unsuccessful, areas searched, and
reasons why that may be the case.

Communications
5. What the future plans are envisioned, any
recommendations, and whether additional
resources required.
6. Status of the case - normally final SITREP
when case is closed, or search is suspended
pending further developments.

Safety
CANADIAN COAST GUARD AUXILIARY - PACIFIC
Safety - Restricted Visibility
• When conducting a parallel search with
multiple vessels in restricted visibility,
consider the following:
1. Possibility of reducing the track spacing
consistent with safety.
2. Consequences of loss of covering as much
search area as in clear visibility.
3. Risk of collision.
CANADIAN COAST GUARD AUXILIARY - PACIFIC
Safety - Restricted Visibility
• Consider a reduction of speed to increase
safety.
• If any vessel has radar problems, they must
immediately inform the OSC. If they can still
see adjacent vessels, the OSC may allow
them to continue the search.
• If they lose sight of the other vessels, they
should inform the OSC and drop astern.

Track Spacing
CANADIAN COAST GUARD AUXILIARY - PACIFIC
Track Spacing
• Track spacing defined will depend on a
number of factors:
1. Size of object be searched for.
2. The prevailing visibility.
3. The wind force and sea conditions.
4. Height of eye in the rescue vessel.
• The track spacing can change depending
upon the above changing.

Multiple Ship Search Patterns
CANADIAN COAST GUARD AUXILIARY - PACIFIC
Multiple Ship Search Patterns
• There a number of systems used:
1. Different SAR units are allocated different
areas, and associated single vessel search
patterns appropriate to that area.
2. Different SAR units perform the same type of
search together, coordinated to cover the
area.
Generally this will be only the parallel search.
CANADIAN COAST GUARD AUXILIARY - PACIFIC
Multiple Ship Search Patterns
1. Different SAR units are allocated different
areas, and associated single vessel search
patterns appropriate to that area.
In this example all vessels and helicopter are
doing parallel search, except hovercraft which
is doing a shoreline search, then parallel.

Radar Search
CANADIAN COAST GUARD AUXILIARY - PACIFIC
Radar Search
• If the position of the incident is not known, a
radar search may be used.
• Rescue vessel can be asked to form a loose
line abreast and maintain a track spacing of
about 1.5 x the detection range of the object.
• The typical radar horizon of a RHIB is about 4
nautical miles.
• Learn what the detection ranges for different
vessels is on your radar.

Final Comment
• Remember the intention of a search is
to find the object(s) being searched for.
• A perfect search pattern while desirable,
is secondary to thoroughly searching
the waters and adjacent coastline.
