Execution of design works – Reconstruction of voltage transformers on the open switchgear 110 / 330kV CHP-6 Kyiv, st. Pukhivska, 1A.

The project envisages the reconstruction of voltage transformers on the open switchgear 110/330 kV CHP-6.
There are no additional factors that affect or may affect the state of the environment, taking into account the possibility of environmental emergencies during the reconstruction.
Emissions of pollutants and noise characteristics of machines and mechanisms used in construction meet the requirements of environmental standards and regulations. Relevant calculations are given in the section “Environmental Impact Assessment”.
The list of residual impacts includes the presence of dismantled structures and materials, as well as garbage, containers, small waste.
The territory of the assembly sites for work is promptly cleaned of debris, containers, small waste that is collected in containers or boxes. Gasoline-impregnated wiping material is collected in a special tub with a tightly closed lid. Waste is transported to disposal sites.
The customer of the project undertakes to inform the public about the planned activity, the purpose of the way of its implementation.
The customer also undertakes to comply with the design decisions in accordance with the norms and rules of environmental protection and environmental safety requirements at all stages of construction and operation of the planned activity.
The facility to be reconstructed has virtually no harmful effects on the environment and, subject to precautionary measures, can be constructed and put into operation.

Institute Energoengproject performed design and survey work as Working Project stage for reconstruction of 330 kV HV line Dniprovska 750 kV – Kremenchuk of ​​2.3 km distance crossing over the Dnipro River between Horishni Plavni and Chikalivka at Kremenchuk district, Poltava region, for NPC Ukrenergo.

The task included the field survey, detailed inspection of structural elements and assessment of the technical condition of the 330 kV towers Dniprovska 750 – Kremenchuk at the crossing of the 330 kV OHL over the Dnieper River, which were introduced in 1985.

The institute has developed technical solutions: repair of towers concrete parts, restoration of protective coating, installation of mesh fencing around the towers foundations, replacement of damaged insulators in garlands, installation of LED signal lighting (night marking at towers), replacement of bird barriers, additional bullet markers by UAVs. Adherence to the necessary environmental protection measures during construction and operation is mandatory.

During the operation of the hydroelectric dam, a sediment is delayed in front of it, which is caused by natural erosion and such activities as construction, deforestation and agriculture. Traditionally, a dam is built with a reservoir sufficient to move sediment for a period of at least 50 to 100 years.

Given the service life of large hydropower plants in the world and the urgency of the problem of sludge for Ukraine, institute of energy and environmental protection Energoengproject gains experience and practical knowledge of successful strategies for sediment / sediment management (ukr. – управлінням осадом / відкладеннями).

Working with a team of international industry experts, we identify problem areas and share best practices in sediment management in different geographical regions and environments.
That is why, together with Swiss and Icelandic colleagues, we are involved in the removal (dredging) of sludge from a large hydroelectric reservoir in Georgia, where the following will be done:

• Design, manufacture, supply, installation and testing of a permanent dredger ready for sludge dredging.
• Installation of a computerized system for monitoring, surveying and visualization, including underwater surveillance, light camera, visualization system, positioning and creation of a basic three-dimensional computerized model of the work area.
• Operation of a dredger for dredging along the upper surface of the dam to clean the lower exits and access channels by removing the material and moving it under water to another outlet for washing.
• Operation of special devices for removal of boulders, debris, sunken trees by underwater work and automatic unmanned devices that dredge small sediment or gravel and large sunken trees from the bottom of the reservoir.

Historically and geographically, European companies have extensive practical experience in dredging development and sludge management, not only in rivers and large reservoirs with large sediments, but also in waterproofing canals and hydroelectric dams.
