Project: River Turbine
The Need: At present there is no exterior source of electricity and so the Mission maintains diesel generators (100kVA). The fuel consumption is over 22L/hour so its use is limited to pumping water from the river into the storage tanks and similarly vital tasks. Generators are only operated for 4-1/2 hours each day, which currently adds up to $35,000(US) each year.
Not having reliable electricity greatly limits equipment usage and increases the cost of providing healthcare. The hospital is equipped with modern x-ray, ultrasounds, sterilizers and other devices that need power and the recently built ICU can only be fully utilized with constant electrical supply.
The Plan:
For over 2 years now the Mission has been working with a company in the USA to custom build a ‘flow turbine’ which should be an ideal solution that will produce constant 24-hour power at a very sustainable rate and affordable cost. The project is to have the turbines installed on 2 floating barges in the Zambezi River close to Chitokoloki Mission which will enhance all aspects of the work by providing a constant 100kVA of 3-phase electrical power. This will replace the existing generators and greatly increase the availability of water for the mission, schools and community as well as provide continuous electrical power at a much-reduced cost.
April 2008
Since the begining of this project there has been need to make many modifications of the design and electronic components which has caused lengthy delays and postponed the shipping of the complete barges, turbines and electronics from Maryland, USA.
This latest report was just received April 4th 2008 from UEK as to the progress on the manufacturing of the turbines and barges.
REPORT
Containers:
The first container was delivered to our shop location this week by the “barge manufacturer” Cianbro, Baltimore. The UEK turbine hoist was manufactured and is part of this container load. The container can only accommodate one barge at a time so there is a lot of space around the four main parts forming the “Barge” that could be loaded with other stuff if you request. There will be need to ship 3 40 foot containers to get all the supplies to Zambia
FIRST Barge status: ready to go.
The second barge to be assembled and ready to test the first of the two UEK turbines in a towed form in the Chesapeake Bay as soon as the electronics are ready.
Second Barge status: assembled at Cianbro’s yard, including hoist apparatus, ready to be used for the test.
Turbines:
We are progressing on both units at the same time and the shop labor is concentrating on the Chitokoloki project. The engineers of Alaska Power & Telephone will assist us in the testing because their turbine is the same design on platform but designed for 5.2 kts water velocity.
Electronic interface and ZESCO Transformer:
We are convinced that our electronic engineer and the Mission’s talents in this field know more about the status of this task whice is the component that has delayed the project. We trust them to make the best choices for the benefit of the Mission Hospital and consequently for UEK’s obligations and responsibilities. We are pleased to hear that ZESCO will provide the required transformers.
Representation of project status:
Platforms, Barges: 100% Completed Ready for shipping
Turbines: 80% Completed 2 months to shipping
Testing: -0-% Not Started 2+ months to shipping
Electronic interface: 50% Completed 2+ months to shipping
This is our best assessment for work on this side therefore shipment should occur within three months as the worst scenario.
