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


Unloading racks No1, No2, No3 and No4:


  • Two twin side unloading racks with 42 bottom discharge units- two for light (No1 and No2) and two for heavy hydrocarbon unloading (No3 and No4);
  • 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 racks No3 and No4 are equipped with bottom discharge units and a product heating and circulation system for sufficient and effective process of offloading;
  • Heavy hydrocarbon unloading racks No3 is equipped with 42 individual heating, circulation and offloading units, so called Modules. 
  • The heavy hydrocarbon unloading rack No4 is equipped with 42 sets of upper heating units for effective offloading of heavy hydrocarbon residuals in RTC’s;
  • In addition, heavy hydrocarbon unloading racks No3 and No4 are equipped with stream supply system for heating of RTCs with steam jackets.
  • The light hydrocarbon unloading racks No1 and No2 are equipped with bottom discharge units for sufficient and effective offloading process
  • Offloading of pyrolysis resins from railway tank cars and loading to the sea tankers;



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);


Unloading/loading rack for 10 RTCs:


Racks for 10 RTCs with length of 220m is designed for offloading pyrolysis resins from railway tank cars, loading gasoline from sea tankers to the railway tank cars and for loading/offloading operations for products such and industrial oils and isopropyl alchohol.


Twin side LPG railway trestle for receipt and discharge of 30 rail tank cars and loading LPG to the gas carrier and vice versa;


The safety devices/equipment for each racks are:


  • Bounded with concrete embankment, with a drainage collector system and close drain tanks;
  • Gas detection system at each bottom discharge unit, 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;


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;



Each rack and offloading/loading devices are 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.
