Bulk Storage Terminal
The aim of introducing long term bulk storage silos was to reduce the cost of warehouse storage and subsequent distribution for GBHL clients. Moreover it became crucial in providing a distribution hub for commodity traders and relief agencies to expand their use of Mombasa to service regional demand.
Construction of the 55,000 tonne bulk silos began early 2006. In Phase 1 a total of 25,000 tonnes of bulk storage was commissioned and in operation by August 2006. Phase 2 with 35,000 tonnes, was completed by mid 2007.
The completed bulk storage facility comprises of:
- One bagging point with 4 bagging lines with a combined capacity of 200mts per hr,
- One calibrated bulk delivery hopper for road,
- two road weighbridges capacity 72mts each with data link to the transit terminal complex and computer network,
- internal paved roads to provide ample parking for customers’s trucks
- retaining walls, storm-water drainage,
- ring-main fire prevention system and
- 10 silos of 5,000 tonnes each plus 4 silos of 1,250 tonnes providing a total capacity of 55,000 tonnes, with related elevators, conveyors and dust extraction systems.
The facility also includes a control room with a data link to the main control room in the transit terminal’ expansion of the delivery complex to include two extra road delivery points.
These additions to GBHL facilities have encouraged the required developments further down the transport chain, which are now reaching completion.
GBHL anticipates that this increased storage capacity, while satisfying current demand, will not be enough to meet future demand. As a result, the design work has already taken place for a third phase providing a further 9 silos of 5,000tonnes each plus 4 silos of 1,250 tonnes – a total long term bulk storage capacity of 105,000 tonnes. This development will also include rail weighing and delivery systems.
Operation of completed bulk storage facilities
The long-term storage silos are connected to the main transit terminal by a 300metre single belt conveyor with a transfer speed of 200 tonnes per hour. The conveyor is encased to protect grain from elements as well as for security and environmental reasons. The conveyor is also fitted with an in line batch weigher capable of weighing 3 tonne batches. The weigher will electronically record weights of bulk grain transfers from the transit terminal to the long-term silo complex. For great safety, the bulk bulk grain on transfer to the long term storage silos passes through a dust extractor at the main elevator.
The GBHL extension, being for long term storage facility has design features to ensure the condition of bulk grain stored does not deteriorate in the silos. In order to preserve the condition of bulk grain in store, the long term storage silos are fitted with temperature monitors and devices for aeration of cargo. They also have facilities for fumigation of bulk grain in store if necessary. This ensures that bulk grain stored on long term basis remains in excellent condition.
Deliveries from the silos may be made in bulk or bags as required. To facilitate bulk deliveries, the extension complex is equipped with 2 bulk hoppers for road and rail deliveries. Each is fitted with 35 tonne load cells. Bagged deliveries are via a bagging plant with a capacity per line of 50mts per hour. One bagging point with 4 lines has already been incorporated and a further point will be introduced as and when required at the next development phase.
The project also includes provision of a two-line rail spur fitted with 140tonne weighbridge for rail deliveries and a road system linking the terminal to the main access roads. In this way, the extension will be able to deal with road and rail deliveries to Mombasa’s vast hinterland as well as interact with the main port for conveyance of transit/transshipment consignments. The extension terminal has a common entry/exit gate for rail and a separate one for road vehicles. The road gate also features two 72mts weighbridges.
