Design, Procurement and Construction

Integrated Investment Design

Risk Engineering Ltd. has extensive experience in developing integrated investment projects covering all required parts/project disciplines. The most significant investment projects developed by the Company are in the energy sector – nuclear energy, conventional/thermal energy, hydraulic energy sector, renewable energy (wind-powered generating plants and photovoltaic power plants), cogeneration capacities.

Kozloduy NPP and Maritsa East 2 TPP are among our largest customers.

Risk Engineering Ltd. is a main participant in project development for the needs of Kozloduy NPP Units 5&6 Modernization Program, which is implemented in the period 1997 - 2005.

One of the large-scale and complex projects, in which the company took part, is the investment project under the contract for the construction (procurement, integrated design, and installation of plant and equipment) of a flue gas desulphurization plant at Maritsa East 2 TPP Units 5 and 6, which was implemented in the period 2009 - 2012. Risk Engineering Ltd. developed the greater part of the engineering and technical designs for the system. A smaller in scope but important part of the design was developed by foreign designers. For that part, Risk Engineering Ltd. performed authorization, which covers verification, correction and supplementing, issuance of the designs on behalf of Risk Engineering Ltd. in order to comply with the current Bulgarian regulatory framework. The design covers industrial plants complex design for unit boilers flue gases desulphurization. The European and current Bulgarian regulatory environmental requirements on the flue gas desulphurization are met with design implementation. In addition to the development of the design different parts, the contract provided for the assistance to the Employer in approving/coordination of designs by state and municipal control services, exercising designer supervision and drafting as-built documentation.
