Planning a search

When planning a search, the Marine SAR controller will have to take into consideration numerous variables. These will need to be constantly revised and updated during the search. 

Search Planning Sequence

The planning sequence encompasses six specific steps:

1 Define the target 

This is the major factor in the planning and implementation of a search. An accurate description of the target can make all the difference. Size, colour, type of vessel, markings, equipment carried, and number of persons on board (POB) are all vital details.

2 Define the datum 

The SAR Controller will calculate the most probable location of the target allowing for

• The accuracy and reliability of available information.

• Time elapsed since the incident.

• Wind direction and strength, and its probable affect on the target.

• Tide / current direction and strength, and its probable affect on the target. 3 Define the Search Area The size of the search area will influence the choice of search pattern and resources required. 

4 Select the appropriate search pattern 

The selection of the appropriate pattern is often made after consultation with the On Scene Command / CRV Skipper.

5 Determine the desired area coverage 

The required coverage of the search area is dependant on the size of the search area, resources available, and time available. 6 Develop a Practical Search Plan A practical search plan is a combination of the points above, and the conditions on scene. The form shown below is an example showing the type of information that may be relevant to the search operation. A record of the key information in any SAROP must be kept on the CRV and updated when required.
