A SUBSEA CONTROL MODULE (SCM) IS A SELF-CONTAINED, PRESSURE COMPENSATED UNIT GENERALLY CONTAINED IN RECTANGULAR METAL HOUSING, WITH HYDRAULIC MANIFOLD, FILTERS, CONTROL VALVES AND PRESSURE SENSORS FITTED WITHIN. THE CONTROL MODULE HOUSING IS FITTED WITH A DIELECTRIC FLUID KEEPING THE TEMPERATURE AND PRESSURE AT AMBIENT LEVELS. A PRESSURE RELIEF VALVE IS MOUNTED THROUGH THE BASE PLATE TO PREVENT THE SCM BECOMING OVER PRESSURISED DUE TO AN INTERNAL HYDRAULIC LEAK. THE FLOW TRANSMITTERS WHICH AUTOMATICALLY CONTROL THE FLOW OF OIL AND GAS FROM A SUBSEA RESERVOIR, THE READINGS FROM THE TRANSMITTERS ARE UTILIZED BY THE SCM TO VARY OR STOP THE FLOW OF OIL AS REQUIRED BY ELECTRICALLY ACTUATING ITS ELECTRO/HYDRAULIC CONTROL VALVES. THE MAIN FUNCTION OF THE SCM IS TO CONTROL AND MONITOR THE SUBSEA PRODUCTION CONTROL SYSTEM (SPCS). IT IS SUITABLE FOR SHALLOW TO MEDIUM WATER-DEPTHS. THE DIMENSIONS OF THE UNIT MAX LENGTH X 1120MM, MAX WIDTH X 915 MM, MAX HEIGHT X 1155 MM, MAX WEIGHT X 1300 KG.
