HEPP and dam maintenance and revision works refer to periodic maintenance, troubleshooting, strengthening, and modernization activities in hydroelectric power plants and dams. Adana-based Enermak Steel Energy Machinery and Engineering explained the frequently asked questions regarding HEPP and dam maintenance and revision activities.
Hydroelectric power plants (HEPP) and dam facilities are complex infrastructure systems operating under high investment costs, requirements for continuous and uninterrupted operation, and harsh environmental and mechanical conditions. The safe, efficient, and long-lasting operation of these facilities depends on the regular inspection, maintenance, and timely execution of necessary revision works for all components, ranging from hydromechanical systems and mechanical equipment to reinforced concrete structures and auxiliary systems.
Maintenance and revision activities are not limited only to troubleshooting occurring failures. They also encompass preserving equipment performance, increasing energy production efficiency, extending operational life, and ensuring that facilities comply with current operational, safety, and environmental standards. Correctly planned and professionally implemented maintenance and revision works minimize unplanned downtimes, reduce operating costs, and carry facility safety to the maximum level. Adana-based Enermak Steel Energy Machinery and Engineering explained the prominent topics regarding HEPP and dam maintenance and revision works.
What is All Types of HEPP and Dam Maintenance and Revision?
All types of HEPP and dam maintenance and revision works refer to the entirety of periodic maintenance, troubleshooting, renewal, strengthening, and modernization activities carried out to ensure the safe operation of all hydromechanical, electrical, mechanical, structural, and auxiliary systems in dams and hydroelectric power plants.
In this context, the current status of the equipment is analyzed. Worn-out parts or those that have completed their service life are repaired or renewed. Performance losses are eliminated, making the systems compatible with current operating conditions. Thus, the continuity of energy production at the facilities is ensured, operational safety is increased, and economic losses are prevented in the long run.
What is the Scope of HEPP and Dam Maintenance Works?
Maintenance works include periodic inspections, preventive maintenance applications, and interventions applied as needed. The main maintenance activities carried out in this context are as follows:
- Mechanical and functional checks of radial, slide, and stoplog gates are performed.
- Maintenance and adjustment procedures for the hydraulic and mechanical systems of gate lifting devices are applied.
- Inspection, adjustment, and testing procedures for butterfly, conical, and gate valves are executed.
- Examination of penstock lines, pipe supports, and expansion joints is conducted.
- Gland packings, sealing elements, and bearings are checked; replacements are made where necessary.
- Maintenance, adjustment, and functional tests of trashracks and trashrake cleaning machines are carried out.
- Periodic inspections of cranes, lifting equipment, and auxiliary mechanisms are provided.
Which Areas Do HEPP and Dam Revision Works Cover?
Revision works include the renewal, strengthening, or modernization of equipment that has completed its service life, suffered decreased performance, or can no longer meet current operating conditions. The revision works carried out in this context are as follows:
- Renewal and re-installation of worn or damaged gates,
- Replacement of old-type mechanical systems with hydraulic or modern mechanical systems,
- Execution of revisions for valve bodies, discs, and drive systems,
- Implementation of local strengthening works and part replacements in penstock lines and bifurcations,
- Renewal of expansion joints and gland packing systems,
- Modernization of automation, PLC, and SCADA systems,
- Integration of additional equipment and systems aimed at increasing operational safety.
Revision works are planned in a way that does not require the complete shutdown of the facility, aiming for minimum operational loss and maximum operational continuity.
How Do Maintenance and Revision Contribute to Operational Efficiency?
Thanks to regular maintenance and correctly planned revision applications:
- The risk of failure occurrence and unplanned downtime is reduced.
- Energy production continuity and system reliability are ensured.
- The continuity of use for mechanical and hydromechanical equipment is supported.
- Occupational health and safety risks are minimized.
- Return on investment and economic sustainability are protected.
Especially in HEPP and dam facilities that have been in operation for many years, revision works allow the systems to be operated safely and steadily at levels close to their initial installation performance.
Why are Engineering, Experience, and Field Management Important?
Unlike new manufacturing projects, HEPP and dam maintenance and revision works require a detailed analysis of existing systems and a strong field experience. The hydraulic structure, operational habits, and environmental conditions of each facility are different. Therefore, intervention methods should be determined specifically for the field instead of using standard solutions. Maintenance and revision works carried out with expert technical staff, correct engineering approaches, and planned field organization ensure the most efficient and sustainable results in terms of time, cost, and quality.
How are the Prices for All Types of HEPP and Dam Maintenance and Revision Works Determined?
The prices for HEPP and dam maintenance and revision works are shaped depending on the current status of the facility, the scope of the work to be done, and the intervention methods. Since the technical infrastructure, operating conditions, and environmental factors of each facility are different, maintenance and revision costs are not evaluated through a standard pricing. In the price determination process, factors such as the age and condition of the equipment, the scope of maintenance or revision, the specifications of the materials and spare parts to be used, labor time, field conditions, and the shutdown requirements of the operation are taken into account. Additionally, whether the work will be performed while the facility is operational or during a planned shutdown plays a decisive role in the cost. Therefore, accurate pricing for HEPP and dam maintenance and revision works is provided through special offers created as a result of field exploration, technical analysis, and detailed work planning.
