ARCONS signed a new project Steel Erection at Bashteel Train Station

Client: Hassan Allam Construction (HAC) – Steel Division

Location: Bashteel, Giza, Egypt.

Project Duration: 2022 – 2022.

Scope of work:

  • Construction of Bashteel Train Station Central Workshops in Giza under the supervision of the Ministry of Transportation, the National Railways Authority and HAC as part of their efforts and dedication to upgrade and develop the transportation network.

Project Facts:

  • The vision for Bashteel Station, which consists of a ground floor and two loft areas with 66,500 square meters of administrative offices and 24,000 square meters of shops, is to create a focal station resting in between Ramses and Giza alleviating the congestion at Ramses Station. It will include two main workshops for train maintenance and a number of service facilities such as fuel tanks, railway carriage washing units and water tanks. In addition, the project’s scope will cover 22 kilometres of railway and track works for a new line.

Greater Cairo Metro Line 4

Client: National Authority for Tunnels (NAT) – Ministry of Transport
Contractors: Orascom Construction-Arab Contractors Joint Venture
Scope of Work: The joint venture will be responsible for the full scope of this New Phase of Cairo Metro Line 4

Firstly, Adly Mansour HUB is now officially the country’s first transit hub , The HUB will connect the New Administrative Capital to the rest of the nation and include a commercial investment zone alongside a full-service transport complex. This HUB connects five different modes of transportation: The third metro line, the electric train route, a railway station, SuperJet station, and Bus Rapid Transit (BRT).‎

The aim of this HUB project is to smooth traffic flows as the build-out of the new administrative capital continues.

One main component of this hub is the metro is Line 3 phase 4B runs along the middle of Gesr El Suez Street, beginning at Nozha station up to Adly Mansour Station with a ramp to a depot area. The extension will serve as a key section of Line 3, which is estimated to carry around 1.5 mn passengers a day. It will also alleviate traffic congestion in East Cairo, providing commuters with a faster transportation alternative

History of Cairo Metro lines

Metro in Egypt is operated by Egyptian National Railways (ENR) and transported up to 3.5 million passengers per day in 2019.

Cairo Metro in Egypt is operated by Egyptian National Railways (ENR) and transported up to 3.5 million passengers per day in 2019.

With a population of approximately 20 million, Cairo is one of the most densely populated cities in Africa.

Egypt Metro is the first metro network in Africa and has been operational since 1990. The network consists of three lines, and a further three lines are planned.

Line 4 (24km) extends from Nasr City, Abbassia and Giza, Line 5 (19km) starts from Nasr City passes Heliopolis and ends at Shubra el Keima and Line 6 (21km) connects Maadi, Old City Centre, Shubra el Kheima.

Lines and routes

Completed in 1989, Line 1 is 43km-long with 4.5km underground section. It has 35 stations. It covers the Egyptian capital from the north to the south.

Line 2, was built in two phases, one in 1997 and the other in 2004. It is 22km-long and serves 20 stations from the north to the south-west, covering the district of Shoubra El Kheima to Cairo University and the pyramids of Giza.

Cairo Metro Line 3 will be 47.87km-long with 39 stations. The line will connect areas of east Cairo starting from the ring road El-asher area and El-salam city through the station of Adly Mansour and ends in Imbaba and Rod al-Farag road on the ring road west of Cairo.

How’s Crude Oil Stored?

Fixed Roof Tank and Floating Roof Tank are the two widely used crude oil storage tanks used in the United States. Let’s delve deep into each to know how its stored –

1. Fixed Roof Storage :-

These crude oil tanks are the most common storage units for oil. While storing, hydrocarbons such as liquids, volatile organic compounds, hazardous air pollutants, and some inert gases vaporize and collect between the liquid level and the fixed roof tanks.

As the liquid level in the tank changes, the gases are slowly released into the atmosphere. An easy way to prevent this is to install vapor recovery units. Using foam chambers is another potential solution. These help cover flammable hydrocarbon or water-miscible liquids having low expansion foam or fire extinguishment.

The foam occupies the vacant space that initially had air. Experts believe that these prevent hazards as it directs all the foam onto the flammable liquid surface, irrespective of the weather condition.

2. Floating Roof Tanks :-

Floating roof tanks are a better option compared to fixed roof tanks as it helps prevent vapor emissions. According to experts, the chances of fire or an internal tank explosion are also less in floating roof tanks.

They further add that these crude oil tanks are the best option for storing stable liquids, with dynamic loads near to nil. However, adverse environmental conditions affect floating roofs as an accumulation of snow and rainwater may result in roof submersing in the stored liquid.

An area of concern with floating roof oil tanks is the dynamic loads that act upon the roof due to the constant splashing of water lead to flooding of roof compartments. This, however, can be corrected by having sufficient stiffness in the circumferential direction near the roof.

Also, when the liquid exits the bank, the floating liquid slowly approaches the bottom leaving behind liquid droplets. This results in the evaporation of liquid droplets in the atmosphere.

How Long Crude Oil can be Stored?

Storing crude oil in above-ground storage tanks is a costly affair as it often tends to lose their viscosity. According to Reuters, a time period ranging between 30 days to 6 months is optimal for storing crude. Beyond this period, chances for the oil to lose its viscosity is high.

How Do You Clean a Crude Oil Tank?

Prolonged oil storage in a crude oil tank often leads to the accumulation of sludge at the bottom of the container. So, it’s essential to remove the sludge periodically.

Here’s you can clean a crude oil tank –

1. Replace the old sludge-tainted oil tank with a new one.
2. Use heating oil additive as sludge dispersants or softening agents.
3. Now, unclog the lines. The use of additives stirs up sludge from the tank bottom and clog oil lines and filters.
4. Next, remove the sludge and clean the tank thoroughly.

To avoid issues from the accumulation of sludge, ensure to clean your oil tank every three years.
