Mbali na hio Grain Silo inayojengwa kando ya Nairobi ICD
Kuna SGR Dry Bulk Terminals zinajengwa Athi River which is like 15km from Nairobi ICD.
Sample kutoka kwa ESIA report ya hizo dry bulk terminals ambazo zitakua zinapokea Fertilizer, Simiti, clinker,chemicals, coals..etc
------------------------
2.2 Design Concept
The Dry Bulk Handling Terminal for non-food products such as clinker, coal and fertilizer will comprise several components among them a standard gauge railway siding, conveyors, diesel powered generators, weigh bridges, Six (6) flat sheds, one (1) with a capacity of 38,500m3, two (2) with a capacity of 40,000m3, two (2) with a capacity of 46,900m3and one (1) with a capacity of 60,000m3, bag loading stations and an administrative block.
At the proposed SGR siding, there will be a tipping pit for the sole purpose of collecting cargo that has been discharged from containers being carried on the wagons. Inside this tipping pit will be a conveyor system with a flow capacity of 600 tonnes/hour for moving bulk cargo to the storage flat sheds. To minimize dust emissions, the tipping pit and the conveyor system will havetheir dust collection systems. Once in the flat sheds, the product can be stored long term or act as a buffer in the event that trains bringing in cargo to the terminal exceed deliveries to Clients by truck. In the event that Clients need to pick their cargo, the cargo will be released from the flat sheds to a conveyor belt system underneath that is dedicated to deliveries at a flow rate of 300t/h. These conveyors will delivercargo to the bulk loading station or to the bagging station through an elevator. Trucks will then be loaded, weighed and dispatched. The bagging station and bulk loading points will all have dust suppression systems in place to minimize dust emissions.
2.3 Planned Scope of Works
The construction phase of the project will entail various works that can be categorized in to mechanical works, electrical and instrumentation works and civil works. Being a new site at Athi River, downtime shall not need to be considered. The initial proposal is to fabricate majority of the structural works off-site at a designated area for hot works. These shall then be connected on site so as to have ample working space.
To enable GBHL to handle bulk cargo consisting of
fertilizer, clinker and coal in Athi River, a storage terminal needs to be constructed together with all associated conveyor systems as below:
The mechanical and piping engineering work to be carried out shall include:
- Construction of Standard gauge railway siding to enable trains to come to site with loaded cargo;
- Installation of two(2) Bagged fertilizer warehouses;
- Installation of one (1)Bulk fertilizer warehouse;
- Installation of one (1) Clinker warehouse;
- Installation of one (1) Coal warehouse
- Installation of two (2)wagon unloading stations
The preliminary electrical and instrumentation works that are envisaged shall include:
- Power supply to all conveyor systems
- Power supply to all metering units, load computers etc
- Installation of switchboards and MCC as well as cable tray routes
- Control cabling for motors, slide gates, weighbridges etc;
- Lighting for the facility
- All additional instrument installation materials, such as field junction boxes, GI conduit cable support, cable tray, ducts, compression fittings, cable glands, instruments support, etc., as required for the system; and
- Minor civil works like chipping of pavement and grouting on the pavements the instruments panels/support, and chipping and refilling of the pavement for conduits.
The civil and structural scope shall involve the construction of all conveyor systems and storage structures required for efficient operation of the plant. Some of the civil works will include:
- Demolitions and disposals as required;
- New drainage system for the facility
- All required structures to support conveyor system and loading points including column plinths and steelworks;
- Cladding for all bulk loading points and towers as required; and
- All necessary anchors and cast HD bolts.
