A total of 36 firms are being invited to submitted bids by 17 December for a contract to upgrade and modify the electricity distribution system at gathering centre 23 at the Sabriya field in the north.
The $50 million lump-sum engineering, procurement and construction contract covers new transmission and distribution systems and a minor upgrade of the gathering centre itself.
More than 20 contractors have until 11 February to bid for a second contract to build crude pipelines between transit line 3 and the Doha water and power generating complex in the north of the state.
The lump-sum engineering, procurement and construction job, also estimated to be worth at least $50 million, involves the replacement of existing pipelines running between the new main crude export pipeline to the oil-fired Doha power and desalination plant.
