Servicing Large Production Facilities: Tanks, Bunds & More

Tanks, reservoirs and containers designed for different purposes and configurations are fairly considered to be integral parts of virtually any engineering system.

Due to the unprecedented demand, manufacturers offer a wide selection of tanks types: hydro accumulators used in water supply systems, storage tanks for drinking and industrial water, condensate tanks, reactants tanks, pressure and non-pressure process vessels, and dozens of other types of various volume, shape and configuration, standard or custom-designed. The companies specializing in manufacturing equipment for huge production facilities typically provide bund, or the so-called ‘bund walls’ construction aimed at preventing the chemical spills.

An individual approach in the design and manufacture saves considerable amounts of money in comparison with standard solutions, which is achieved through accurate estimating of the optimal volume and weight of the tank.

The manufacture of tanks and containers in accordance with individually specified geometrical characteristics reduces the cost of construction and installation works as well as the cost of existing facilities reconstruction or upgrading. Stainless steel material used in tanks manufacturing increases the lifespan of the product up to 30-40 years, plus the construction is hardly suitable for corrosive environment development, due to the limited iron oxide (rust) formation capabilities during the use.

In addition, equipment providers produce voc removal and odour control systems, to decrease the concentration of dangerous chemical compounds and biological and carbon odour control accordingly. Taking into account the rigid norms and standards the large production facilities have to comply with, installing such equipment is obligatory in nine cases out of ten.

How It Works: A Borehole Drilling Rig

A borehole drilling rig is designed to lift and lower the drill string and casing in the well, retain the pressure exerted on the drill string during drilling, accommodate the drill block system and its parts, the pipe and the equipment needed for drilling.

When another drilling site for oil and gas is launched the professionals take advantage of using metal tower and mast rigs, and frankly speaking, mast construction are used more frequently in comparison with the tower ones. Such choice is explained by a less complicated and faster process of installation. Tower rigs are overwhelmingly erected for deep exploration, while mast rigs are installed for production purposes.

Derricks may differ in payloads and height. According to practice, drilling to a depth of 1200-1300m demands installing the 28m height rig, the wells of 1330-3500m need 41-42m rig to be mounted, while the projects exceeding 3,500m demand 53+ meters derricks.

Today the industry professionals do mostly resort to A-frame mast derricks, comprised of two columns connected at the top of the crown with connection blockers and attached at the bottom to support the hinges. A range of researches in geophysics as well as practical data confirms that the construction mentioned above is considered to be the most efficient one for residential systems.
