Hindustan Institute of Maritime Training Chennai Handling Deceased Persons · · · · Searching for or recovering bodies is not part of SAR operation but may be necessary. Bodies in an aircraft should not be removed without authorization from the SMC except under compelling circumstances. Identify the deceased If a body is picked up or if a survivor dies on the ship, then prepare a waybill, stating therein --- Name, age, place, date, time and cause of death. Transmit the same to the appropriate RCC. Place the body in a proper bag, slow it in a suitable place and hand it over to the appropriate authorities along with the waybill.


Assisting a Ditching Aircraft · · · · · · Maintain continuous communication (preferably by voice) with the aircraft. Locate the aircraft visually or by radar. Transmit homing bearing or transmit a signal to enable the aircraft to take his bearing. By day make black smoke By night direct a search light vertically up, but not towards the aircraft, and switch on the deck lights. Give following information to the pilot --Wind direction and force Direction, height and length of primary and secondary well State of sea and weather. Set your own course parallel to the aircraft's course. If his course is not known then set a course parallel to the main swell

Contact With Media Dealing with the media is normally the responsibility of the RCC, but sometime the rescuing ship, bringing survivors to a port may be approached by the media for information, in which case the following steps should be taken 1. Appoint a spokesperson who shall only give the facts of the case and shall avoid giving any personal judgement or demeaning information about the · Rescued or missing persons. · Competence of the Master or crew involved. · Conduct of the SAR operation. · Reason for the accident or how it could have been avoided 2. Do not give the names of the missing or distressed persons till their relatives have been informed. 3. Do not give the names of the owner or operator of the ship till they have been informed. 4. Do not reveal the names of the informants.

Hindustan Institute of Maritime Training Chennai Providing Escort Service 1. 2. 3. 4. 5. 6. 7. Provide moral support to the persons on the distressed ship. Assume the navigation and communication functions of the ship, Visually inspect the exterior of the craft for damages. Give advice on ditching the aircraft and abandoning or beaching the ship. Provide illumination during the above operations. Provide emergency and survival equipment Direct other SAR facilities to the scene.

On Scene Co Ordination When two or more facilities are working on the same SAR mission, then one of them may be required to co ­ ordinate the activities of all other facilities. The OSC shall be nominated, as early as possible, by the SMC who is located at the RCC, which is involved in the SAR mission, or by mutual agreement between the ships. The OSC may be an aircraft, a ship, any other SAR unit or a nearby facility. Separate co ­ordinators may be appointed for surface and aircraft activities. Normally the person in-charge of the facility which arrives first on the scene will assume the functions of the OSC till he is relieved by the SMC. Functions of OSC 1. Inform SMC on assuming duty. 2. Receive search action or rescue action plan from the SMC or make such a plan yourself. 3. Modify the plan as required, in consultation with the SMC, if ­ additional facilities arrive additional information is received, of weather changes 4. Monitor performance of other facilities 5. Ensure safe operation of the search activity, with proper separation 6. Maintain record of the operation of the facilities Arrival and departure of the facilities Areas searched Track spacing used Sightings and leads reported Actions taken and results obtained 7. Establish a traffic co­ ordinating system amongst the ships proceeding to the rescue. 8. Release the facilities if not required or ask for mote specific facility as required. 9. Consider the risks inherent in any SAR operation against the chances of success and the safety of the SAR personnel. Some practical concerns could be as follows Danger of the distressed craft causing harm to the rescue facility Adverse weather conditions. Insufficient information from the distressed craft Low probability of giving effective assistance. Problems of accommodating and providing food and other amenities to a large number of survivors

Hindustan Institute of Maritime Training Chennai Adverse effect on the stability of the ship due to the presence of large number of survivors Suitability of the ship for helicopter operations 10. Stop engines occasionally during the search to listen for cries for help. 11. Collision regulation will apply at all times. Use manoeuvring and warning signals as required. Situation Report ( SITREP ) 1. Send initial SITREP in short form as soon as sufficient details are available, without waiting for all the details. Subsequently follow it with periodical reports in full form without repeating the earlier information. 2. Send "No change" SITREPS every 3 hours if there is nothing new to report. 3. Contents of the SITREP are as follows · Prefix ( Mayday, Pan, Saycurity ) · Name of the recipient · Number of the report · Identity of casualty · Position · Situation · No. of persons at risk · Assistance required. Additional contents may be as follows · Description of casualty · Weather · Initial action taken · Search area · Co ­ ordinating instructions · Future plans · Names of the survivors · Name of the facility carrying the survivors Search Area ( A ) 1. Establish the datum depending on the · Reporting time of the incident and time lost till a facility reached the scene. · Position of the distressed craft as determined by all possible means. · Estimated drift due to wind and current 2. Determine the Track Spacing (S), with the help of the prescribed tables, depending on the search object, visibility and wind & sea state , as follows --S = tabulated spacing x weather factor

Hindustan Institute of Maritime Training Chennai 3. All facilities should proceed at the same speed (V) which will be the maximum speed of the slowest ship 4. If the search has to commence immediately then the area of the search shall be a square of side 20 miles, with the datum at the centre. 5. If time is available for computing the search area then calculated the area to be covered by each ship in a certain time ( T ) as follows --A ( for each ship ) = S x V x T 6. Reduce the values of S, V & A in restricted visibility 7. Total search area for all the ships together shall be in the form of a square with the datum at the centre. 8. Divide the total area into sub-areas of appropriate size and assign them to the various facilities accordingly 9. Place a marker at the datum for future reference. 10. When alone, start the search using the Expanding Square search pattern. As other facilities arrive, select one of the other suitable patterns. 11. Radar search is effective if number of ships are available. There is no prescribed pattern but all the ships should proceed in a single line abreast of each other, maintaining a track spacing of 1 ½ times the prescribed detection ranges for different objects. Termination of search If one search of the selected area is unsuccessful then · Re ­ search the same area after allowing for additional drift during the internal, or · Expand the area after allowing for additional drift, or · Expand the are more in one direction than in the other, or · Determine and search in a new area based on additional information Terminate an unsuccessful search, in consultation with the SMC, provided that there is no possibility of · The survivors being found in the area searched · Detection of the object · The survivors being alive. · The facilities being able to continue with the search. If the search is successful then · Conduct the rescue operations as described earlier. · Ensure that all survivors are accounted for

Hindustan Institute of Maritime Training Chennai · · · Gather all possible information from the survivors and relay it to the SMC Inform all search facilities that the search is terminated. Send the final SITREP.
