3. Kindaruma Power Station
1.0 Introduction
Kindaruma Power Station

4. 1.1 Introduction
Generates High Voltages making it Most Vulnerable equipment to fire risks.
Its given high priority in protection against fire risks.

5. Generator Fire Protection System
1.2 Introduction
Generator Fire Protection System
Protection scheme comprising of heat sensors, smoke sensors, carbon dioxide gas cylinders and control system with periphery devices.
This system automatically put off Generator fire upon detection

6. 2.0 Problem Statement
Fire protection was installed in 1999 with Generators 1 & 2 using a common centralized control unit and fire suppression system. 1 2
Common controller broke down in 2016 and OEM (Notifier UK) was contacted. 3
They advised on Complete Systems Rehabilitation using their latest generator fire protection. . 3
Quoted Cost for rehabilitation was too high and Management opted for an open tendering process

7. 2.1 Problem Statement
Tendering
Masinga and Kindaruma were facing the same challenge
The tender was advertised for both Power Stations on 23rd November 2016
Bids were opened on 23rd January 2017 and three
contractors submitted their bids.

2. 
Total for Schedule 2 Kindaruma
31,790,287.20
Grand Total
61,389,601.20
Due to budget constraints the Contractor was awarded Schedule 1 Project.
Top Management challenged EH team to carry out Kindaruma works

9. Materials acquisition
3.0 Solution
Project Execution
A team of Mechanical and Electrical staff was formed.
It was mandate to carry out the following tasks:
Design Work
Installation Works
Materials acquisition
Commissioning

10. 3.1 Design

11. Design Work
Smoke Sampling Pipes.

12. Design Work
Smoke Detectors

13. Design Work
Strobes and Buzzers for audio Visual Alert.

14. Design Work
Fire Protection Control Unit (SHP)
Microprocessor based unit configured for a wide range fire protection applications.
Primary inputs are Smoke while Secondary inputs are Thermal.
Outputs.
Audible and visual fire alarms.
Machine emergency stop .
Release of fire suppression gas.

15. Fire Suppression System
Design Work
Outputs
Fire Suppression System
Consists of carbon dioxide gas cylinders inter-connected together by high pressure hoses.
Hoses are connected to carbon dioxide distribution pipe known as Manifold.
The first carbon dioxide cylinder is equipped with a CO2 puncturing solenoid which is referred to as a pilot CO2 cylinder.

16. Material Acquisition & Installation
Major Items were sourced from Kamburu & Kiambere
Other materials were procured locally
The installation works took a total of six weeks
Installation
Mounting
Cabling
Wiring
Fabrication
Testing & Commissioning

17. Installation Work
Cabling and fixation of smoke sampling pipes.

18. Installation Work
Mounting of sensing and alarming devices

19. Installation Work
Wiring of control relays
Wiring of vesda control units

20. Installation Work
Fabrication of fire suppression unit
Wiring of gas releasing solenoid on the fabricated suppression unit.

21. Installation Work
Kindaruma Fire System Central Controller
New
SHP panel
Old
Notifier panel

22. Testing & Commissioning
Functional checks for the various systems
Equipment was then subjected to a live test.
Puncturing of Co2 gas cylinders
Machine shutdown was witnessed by simulation of smoke to the fire protection system

23. LIVE TEST

25. 4.1 Benefits
Project took advantage of another Scheduled Outage (Intake Gate Rehabilitation) thus saving the Company a further Ksh.21,000,000 in Capacity Revenue.
Built internal capacity (on job training) and improved employee morale
By use of Internal Capacity, the Company realized saving of Ksh. 34,051,026 (Through Project Savings and Capacity Revenue)

26. 5.0 Conclusion & Way Forward
5.1 Challenges
Materials procurement - Delays in delivery of Materials.
Challenges since we were working on untested waters.

27. 5.1 Lessons Learnt 1
With team work, proper planning and determination you can beat any challenge. 3
KenGen has well skilled and capable personnel to undertake challenging projects. 2
Using old fire protection manuals the team perfected in design and installation of the project.

28. Standardization of fire protection system in the Company.
5.2 Recommendations
Continuous specialized training to assist the team in sustaining systems
Standardization of fire protection system in the Company.
Management to Approve funds to install similar Systems in other Stations
Maintenance of existing fire protection systems in the company.
