SHUTDOWN SYSTEM BETWEEN FPSO AND SHUTTLE TANKERS

OVER THE PAST TEN YEARS HAS MANUFACTURED RADIO TELEMETRY SYSTEMS FOR SHUTDOWN OF OIL EXPORT FROM PLATFORMS AND FPSOS. THE TELEMETRY LINKS THE OIL EXPORT FACILITY WITH THE OFFTAKE TANKERS TO ALLOW SHUTDOWN AND DIS-ENGAGEMENT IN THE EVENT OF AN EMERGENCY.

SHELL’S ANASURIA FPSO IS FITTED WITH TELEMETRY

DUE TO INCREASING DEMAND FOR SYSTEMS WITH VERY LOW FAILURE RATES AND HIGH COMMUNICATIONS AVAILABILITY, HAS INTRODUCED THEIR DUPLICATED SYSTEM. THIS HAS BEEN PRIMARILY DEVELOPED FOR SHELL IN THE NORTH SEA, AND IS NOW INSTALLED IN MOST OF SHELL’S FIELDS REQUIRING OFFTAKE TANKERS, DRILLING RIGS AND WORKOVERS.

THE EQUIPMENT PROVIDES;

  • HARDWARE REDUNDANCY USING SPLIT BACKPLANES
  • DUPLICATED COMMUNICATIONS USING SEPARATE DATA LINKS
  • BUMPLESS TRANSFER BETWEEN MAIN AND STANDBY CHANNELS
  • MULTIPLE COMMUNICATION PROTOCOLS AND MEDIA EG RADIO, MICROWAVE, FIBRE-OPTIC.

AN IMPORTANT FEATURE IS THE ABILITY TO COMMUNICATE WITH MULTIPLE SITES, THIS ALLOWS TANKERS OR DRILLING VESSELS TO MOVE BETWEEN DIFFERENT FIELDS. FOR INSTANCE THE SHELL SITES INCLUDE,

  • FPSO AT TEAL AND CURLEW FIELDS,
  • PLATFORMS AT FULMAR, KITTIWAKE , F3, AND CORMORANT.

THE SYSTEM TYPICALLY CAN BE USED TO SHUT DOWN PUMPS, QUICK RELEASE COUPLINGS, HOSE VALVES AND DISCONNECTS MOORINGS, AS REQUIRED FOR THE SAFETY OF THE FIELD.
