SHIP'S BRIDGE EQUIPMENT - (EPIRB) EMERGENCY POSITION INDICATING RADIO BEACON

Updated on March 24, 2012

FROM THE EDITOR'S DESK :

Dear Visitor,

I have put in all my efforts to provide the details of "EPIRB " (i.e. EMERGENCY POSITION INDICATING RADIO BEACON )  in very simplified language.

Also, I have endeavored to put in the details of the usage of this instruments on board a ship along with its installation requirements.

I hope this information will be of great importance to the visitors, particularly to the marine personnel's and nautical students.

You are kindly requested to pass your suggesations and comments directly to me.

Thanks & Regards

THE MARINE EPIRB

(EPIRB) EMERGENCY POSITION INDICATING RADIO BEACON :

The word "EPIRB" stands for EMERGENCY POSITION INDICATING RADIO BEACON. The on board ship requirements of EPIRB are governed by CHAPTER - IV , REGULATION- 7 of the SAOLAS CONVENTION.

OPERATION :

An EPIRB is used to transmit the position of a vessel in distress.There shall be means of float free arrangement of an EPIRB on board i.e. the EPIRB must be fitted with a Hydro Static Release Unit , which in case the vessel sinks and manual operation of EPIRB has not been carried out ; HRU automatically releases the EPIRB after the vessel sinks by 1.5 to 4 mtrs .

The EPIRB when comes in contact with salt water , its electronic mechanism stars acting and activates the EPIRB , which then starts transmission of electromagnetic waves which contains following data in electronic form :

  • Ship's name
  • Call Sign
  • MMSI No.
  • 14 digit MID no.
  • EPIEB's location ( in Lat. and Long. )

The above data is then transmitted to the concerned satellites and , satellites transmit this data to the LUT's ( Local User Treminal) --->MRCC(Mission And Rescue Co-ordination Center )------> RCC ( Rescue Co-ordination Center ) ; the RCC then arranges the SAR facilities to proceed at the distress position and perform the Search And Rescue operation.

There are basically two types of MARINE EPIRB's

  1. COS-PAS SAR SAT EPIRB :

It transmits the data / distress signal to the geostationary "COS-PAS "

SEARCH AND RESCUE SATELLITE.

It transmits the signals on frequency :- 406 MHz

Hoaming frequency :- 121.5 MHz

2. Inmarsat EPIRB :

  1. It transmits signals to the Inmarsat Geostationary satellites and it gives its position

        continuously so it can be homed also by the air crafts.

        It works on the frequency 1.6 GHz

MARKINGS AND SPECIFICATION :

  • Must be of highly visible color and be fitted with retro reflective tapes.
  • Must be capable of sustaining the drop height of 20 meters.
  • must be made up of buoyant material.
  • must be capable of sustaining the heat from sunlight
  • Electronic portion must be safe for 5 minutes when put in to the 10 metes water depth.
  • Must be so fitted to avoid inadvertent activation .
  • Must be arranged for float free system and be activated when in contact with salt water.
  • Must be capable of manual activation and deactivation.
  • Battery must be capable of operating period of 48 hours.
  • Maker's name , model no and date of manufacturing must be marked on top
  • must be provided with  audio- visual means , to  indicate the state of activation.

      your post is wrong . cospas sarsat satelllites are not geostationary but low earth orbitting satellites . and epirb does not gives its position to satellite but its calculated by doppler shift by LUT .
