Our field of activity consists of:

  • unloading, loading ships and barges and storing butane, propane, their mixtures and automotive gas
  • preparing propane / butane mixtures (automotive gas)
  • delivering butane, propane, their mixtures and automotive gas.

The terminal is located on a new platform in Navodari/Cap Midia – Constanta County.
The terminal has an access quay 120 m long and 4 m at the top, ending in a docking pier 40 m long and two mooring buoys North and South of the pier. The quay supports the liquid and gas pipelines which ensure the connection to the installations of the terminal.

These facilities allow the mooring of ships 125 m long with a draft of 7.2 m.
The connection to the manifold of the ship is ensured by a set of flexible hoses of stainless steel of 150 mm for liquids and 100 mm for vapors, which ensures an unloading rate of approximately 300 m3/h.

The storage facility has 10 cylindrical tanks with a capacity of 400 m3 each, laid horizontally, in groups of two, assembled in concrete retention vats.
Ships can be unloaded / loaded in / from storage tanks, and in parallel in / from CF cisterns.

The CF ramp has 8 mobile operation arms placed on two loading lines (4 on a line) and ensure a front of 8 CF cisterns which can be loaded / unloaded simultaneously directly from the ship or with the 4 cargo electric pumps with a capacity of 50 m3/h each. The operated quantities are controlled by volume flow meters corresponding to each arm and two bridge scales on each operation front.

The automotive ramp has two bridge scales and allows the simultaneous loading of two truck cisterns of 40 m3 each with three electric pumps for commodities with a flow of 12 m3 each.
The tank park has a measurement skid (mass flow meter) which meters the quantity received from the ship. This allows the precise monitoring of the quantities managed from and to the ship.

All the loading/unloading and gas mixing procedures are automatically ordered, monitored and controlled by the DCS automatic distribution system, but it is also possible by manual control, directly by the operator.

The terminal also has 3 LPG electric compressors which are used for various maneuvers between tanks, and especially for unloading CF cisterns by introducing gaseous LPG in cisterns and increasing the pressure inside.

In order to cool the tanks and cisterns (CF and automotive) with sprayed water in case of overheating or fire, the terminal has a cooling / fire extinguishing water management system made up of a concrete tank with a capacity of 1200 m3 and a pumping station made up of a pressure maintaining electrical pump and 3 motor pumps with an individual flow of 350 m3/h. The surface fire extinguishing system is started in case of danger or for tests.
The entire terminal is fitted with gas and flame sensors which trigger the alarm in case of fires or gas leaks.

The product installation has manual valves operated depending on the operation to be performed by on-site operators and automatic valves, electrically controlled and pneumatically operated. Automatic valves are operated either by set procedures or at the discretion of the operator from the automatic control desk.
The compressed air that is necessary for pneumatic operation is generated by a compressed air station made up of two 10-bar electric compressors, a 500-liter buffer tank and a drying / filtering station for instrumental air, all automatically operated.

The discharge of safety valves line valves, and the voluntary degasification of certain lines are guided and accumulated in a dispersion stack where the gas is diluted with steam and is dispersed in the atmosphere at a height of 14 m. The necessary steam for the process is generated in a separate steam generation station at a pressure of 6 bar.
The terminal has a technical-administrative office where DCS operators and the management and coordination personnel work.

The products which are sold to be used as household and engine fuel are mixtures of two basic components, propane and butane. The two components result from the primary or destructive processing of crude oil and its derivatives, by separation from the other components. At atmospheric pressure, propane and butane are in a gaseous state (vapors) and, in order to reduce the transportation volume in average by approximately 200 times, are liquefied by compression.
