Base oil terminal

The Base Oil Terminal is built on 29 000 sq.m. , on “ Marine Antipollution Enterprise “ JSC territory, in the Eastern Part of the South Industrial Zone. Investors were “ Prista Oil Holding” ltd and “ Marine Antipollution Enterprise” JSC and the investments were about 10 millions Euro. It was built for the period of one year. World leading technology manufacturers and facilities were used during the construction and the еquipment is provided by leading high-technology companies from Denmark, Holland and Germany. The terminal is one of the most modern in Europe as well as one of the largest specialized terminals in Black Sea.

 There are 16 tanks on terminal’s territory with a total capacity of 24 000 cub.m. It possesses a pier, which has the scope of receiving tankers with 130 m. length and max. draft of 8,00m. The following facilities were built on terminal’s territory : technological pump station, railway trestle with a capacity of loading/discharging 8 railway tanks simultaneously, auto loading/discharging trestle and as well as Control Room. The terminal has a possibility of a 24-hour vessel service, including electricity and fresh water supply, as well as waste treatment. There are 24-hour security, as well as video overlook.

All of the ecological requirements were observed during the building. All the safety and anti-breakdown measures are taken into count. As a guarantor is “ MAE” JSC – company with 35 years of experience in controlling and preserving during tankers’s handling, possessing the only Shore Waste Treatment Plant in Bulgaria for treating oily waters, as well as specially trained crew and technology.

Base Oil , because of which receiving, storage and expedition, the terminal was built,are used as a components during motor, industrial and other oils production.

Since 2012 on the basis of a contract signed by PS Trading, Geneva, there are  gasoil fuel treatment. For 2013 there are over two times increase according to the previous year.

All the tanks are situated in a steel-concrete fence divided into 3 sections. All of them are constructed in the way that in case of a spill of the tanks inside, it can absorb quantity equal to the volume of the biggest one:

Section A-  area 2500 sq.m., H of the walls 750 mm.

Section B- area 3100 sq.m. H of the wall 1050 mm.

Section C- area 2560 sq.m., H of the wall 1200 mm.

The sections possess regular floor scopes and drainage ditches, as well as shafts for collecting and pumping the rain waters and spills, and it has direct bond with the Shore Waste Treatment Plant. Tanks from 1 to 12 all have thermal insulation. The tanks are equipped for all of the products according to the requirements : manholes for samples, for measuring, for circulation, draining fitments. Tanks 13 to 16 has a fire systems installed for extinguishing foam with preparation Shtamex F15, irrigation system for cooling the tanks, as well as 2 booms with stream nozzles next to them. For measuring temperature in the tanks we use equipment type “ Platina 100”, situated in the bottom part of every tank, as well as in the top part for measuring temperature above the cargo for anti-fire reasons. For the levels of the cargo inside the tanks we use radar level gauge type “ VEGA”. All of the data is possessed in microprocessor system.

Pier

It is designed for receiving tankers with DW up to 10 000 tons. The base oils are transported with a corrugated hoses Dy 150 over pipelines Dy 250 and Dy 150to the manifold. The corrugated hose is equipped with automatic with isolation valve for cutting the link tanker-shore in case of a breakdown.

The gasoil is transported with a corrugated flexible hose Dy 150 over pipelines Dy 150 to the four specialized tanks. The corrugated hose is equipped with automatic with isolation valve for cutting the link tanker-shore in case of a breakdown.

There are also fresh water pipeline Dy 150, as well as Dy 200 pipeline for air-blowing by a shore based compressor.

Pump Station

Pump station includes 6 pumps for receiving the products from the tanks and transporting it to the railway and the auto trestles as well as the pier. There are two types of pumps:

Q= 150 c.m / hour , H= 0,6 Mpa, N=45 kW ( pumps 1 to 4 )

Q= 60 c.m./ hour H= 0,6 Mpa, N= 22 kW ( pumps 5 and  6)

The pumps are rigged over concrete foundations with height 50 mm above the floor, and all of the collectors and pipelines are rigged over metal ankers and constructions.

Near Tanks 15 and 16 over concrete foundation there 2 pumps Q= 60 c.m./ hour H= 0,6 Mpa, N= 22 kW ( pumps 7 and 8). They are supposed for handling cargo with flash point over 55 C and service tanks 13 to 16.

At the end of the railway rut, over concrete foundation there are pump 11 Q=60 c.m./ hour H= 0,6 Mpa , N= 22 kW, used for direct treatment for molasses and sunflower oil.

Control Room

All operations are secured and followed from a control room , equipped with microprocessor system, including 2 radio stations, controllers and visualized scheme for the loading and discharging process. The system is used fot handling, control and report of the process of loading and discharging tanks, railway and auto tanks. Main modules are: sensors ( level, temperature and expenditure ), controllers used for handling pumps and stations for visualization and controlling of the process.

Auto Trestle

It is a concrete part, in the middle of which is situated trestle for service for the auto trucks. Half of it is covered with steel construction. It is 3,4 meters high and 1,6 meters wide. There are three loading sleeves – two for base oil and one for gasoil. They are equipped with loading meters, filters and stopcocks. The link between the pump station and the auto trestle is made by 4 Dy100 pipelines. The trestle is connected to drainage tank in order to protect from dirty and rainy waters.

Railway Trestle

Situated in the Eastern End of the terminal over railway ruts and has a ground 12x54 meters. The platform is in the middle and services railway tanks from both sides. 8 tanks can be handled simultaneously, and the trestle is covered by a steel construction. For collecting eventual spoils there are drainage shafts, which are used to transport oily or rainy waters to special tank. There are 2  pipelines connecting the trestle and the pump station: Dy150 and Dy200 for transformer oil and base oil respectively. There are different pipeline Dy 150 for gasoil. They are mounted on a trestle with height 5 meters. Loading is made with 8 loading sets, equipped with pneumatic valves against overloading of the tanks.

Technological pipelines

Include lines to the warehouse tanks, from the tanks to the pumps, from the pumps to the auto and the railway trestle and from the pumps to the pier. They are situated on first level in the sections over two store foundations.
