Hi
Welcome to my blog!
SAR is not a common operations for a Merchant ship but good knowledge on it may help ship Master/ officer to handle it standard way.
This article might help you to gather/ refresh some of your understanding regarding SAR operations and various SAR patterns.
Following are immediate action by a Ship Master during a SAR operations:
*Post extra look out.
* Inform C/E to ST-By engine, but at full sea speed.
* Note down deviation time, position and ROBs.
* Inform owner/ charterer about the deviation.
Folowings are the Assigned Duties to Officers (by Master):
C/O to prepare:
* Prepare rescue boats and ready for immediate launching.
* Extra life jackets, life buoys, buoyant life lines, line throwing apparatus readily available.
* Rig guest warp, accommodation ladder, scrambling nets and life lines running from bow to astern at
the water edge on both sides.
* Prepare crane/derricks with cargo nets for recovery of survivors.
* Test search lights, signaling lamps, torches.
2/O to prepare:
* Ship’s hospital to receive casualties and prepare stretchers, blankets, foods, medicines.
* Plot both vessels’ positions and establish course to rendezvous at maximum speed and update ETA.
* Plot other vessels within the search vicinity together with their respective movements.
* Change over to manual steering.
* Plot search pattern.
* Keep continuous radar watch. Track all vessel in the vicinity.
* Contact RCC via CRS.
* Maintain communication radio watch and update distress information.
* Monitor weather report.
A Ship Master should consider following factors during a SAR operations:
* Size of area to be searched.
* Type of distressed craft.
* Size of the distressed craft.
* Meteorological visibility.
* Cloud ceiling.
* Type of sea conditions.
* Time of day.
* Arrival time of datum.
Hope above information helps you during SAR operations. Now let’s refresh some common Search patterns. Normally three basic search patterns are used. Namely:
Search Patterns:
* Parallel Sweep Search
* Expanding Square Search
* Sector Search
Parallel sweep search (PS)
* Used to search a large area when survivor’s location is uncertain.
* May be used with single or multiple vessels.
* Commence search point (CSP) is one of the corners of the search area.
* CSP may be a corner of a sub area if a large area is to search.
* It is ½ track space inside the rectangle from each of the two sides forming the rectangle.
* Orientation is generally in the estimated direction of drift of the search object.
Parallel sweep search by one ship:

Parallel sweep search by two ships:

Expanding square search (SS)
* Most effective when location of object is known to be within close limit.
* CSP (Commence search point) is always datum.
* First leg usually oriented into the wind.
* Suitable for use by a single vessel or boat.
* Used when searching for persons in water.
* Search object with no leeway.

Sector search (VS)
* Most effective when the location of search object is accurately known.
* Search area to be small.
* Used to search a circular area.
* Center is datum position.
* Datum may be marked by dropping a suitable marker, such as a life buoy.
* Search radius is normally 2 – 5 n. miles for vessels.
* Each turn is 120°, normally to starboard.
* Second search leg is 30º off from the first leg.
* CSP (Commence search point) is one side of the circular search area.

Conclution:
Actually, we never hope to have such contingency as a Seafarer, so as to have some blockage on our learnings. But during contingency, such informations helps us a lot. Hope this short article would be benefited to our beloved seafarers.
