BST Terminal Railway Road Tanks (RTC) offloading is organized by:


  • Two twin side unloading racks with 42 bottom discharge units- two for light and two for heavy hydrocarbon unloading;
  • Each rack is estimated to have a receipt of 2 routes with 42 tank cars each;
  • The estimated tank car according to the Customer’s data we have taken the 60-ton tank car with length by the coupling axis of automatic coupler equal to 12.02 m;
  • Bottom discharge Units for offloading of rail tank cars
  • Heavy hydrocarbon unloading rack is equipped with bottom discharge units and a product heating and circulation system for sufficient and effective process of offloading;
  • The heavy hydrocarbon unloading rack is equipped with 42 sets of upper heating units for effective offloading of heavy hydrocarbon residuals in RTC’s;
  • The light hydrocarbon unloading rack is equipped with bottom discharge units for sufficient and effective offloading process
  • The RTC movement from the Partotskali RTC receiving railway station to the unloading racks and vice versa is done by three BST owned diesel locomotives;




The Unloading Rack Parameters:


  • 500 meter-long roofed facility with twin, bidirectional rail roads;
  • Number of simultaneous offloaded RTC from one rack-84 RTC, with two racks-168 RTC
  • Each unloading rack is equipped with utility water points for cleaning activities;
  • Each external side of the rack is laid with the product collectors which are jointed in common pipelines. The heavy oil collectors are thermally insulated and equipped with heat tracers (steam heating system);


The safety devices/equipment for each unloading racks are:


  • Bounded with concrete embankment, with a derange collector system and two close drain tanks (2 x 72 M3 each, and 4 x 72 M3 volume for two racks);
  • Gas detection system at each bottom discharge unit (42 piece detectors, whole amount of 168), linked with a SCADA gas alarm system in a combined control room;
  • Complete automatic firefighting system, with redundant firefighting pipe work, topside foam generation injectors;
  • Equipped with shut down and manual call point push buttons at fixed locations;
  • Clearly marked emergency escape routes and ladder ways at multiple locations;
  • CCTV security cameras;


Each rack and BDU is monitored and maintained by an approved preventive maintenance planning system:


  • Scheduled BDU maintenance;
  • Scheduled railroad maintenance, rail clearance measurement, rail slippers condition monitoring/change and rail crossing lubrication;
  • Scheduled gas detectors calibration;
  • Scheduled examination of firefighting systems;
  • Scheduled grounding system verification/examination.
