Urucu – Manaus gas pipeline-Spotlight

Petrobras has begun work on the Coari-Manaus gas pipeline which is to carry natural gas from the Urucu hydrocarbons province, located in the municipality of Coari (state of Amazonas), to the state capital, Manaus.

The Urucu-Manaus pipeline will be 670 kilometers in length with conclusion scheduled for March 2008. In the first stage of its operation, the pipeline will transport 4.7 million cubic meters of natural gas daily.

The gas will be used largely to supply the thermoelectric power plants generating electricity to Manaus and the municipalities adjacent to the pipeline. The natural gas will substitute diesel and fuel oil currently used to generate all the electricity produced in the state of Amazonas.

Currently, there is only one existing line that carries liquefied petroleum gas (LPG) from the production facility in Urucu to Coari. A line parallel to this, 285 kilometers in length will be constructed to carry the LPG (GLPduto), while the existing pipeline will be switched to carrying natural gas.

The following stretch between Coari and Manaus will run for a further 385 kilometers, the entire undertaking thus involving a total distance of 670 kilometers between Urucu and Manaus.

A further 125 kilometers of lines will be built to transport the product to the main city in each one of the municipalities - Coari, Codajás, Anori, Anamã, Caapiranga, Manacapuru and Iranduba located along the course of the pipeline.

Approximately R$ 500 million have already been invested prior to the start of construction, notably in the clearing of 30 sites along the route of the gas pipeline. All the 10" and 20" diameter pipe sections have been acquired and are already in position at the respective cleared sites.

The Urucu – Manaus is made up of three sections. The first of them, section A, is the GLPduto Urucu-Coari stretch, work on which will be executed by the OAS/Etesco consortium at a cost of approximately R$ 342.6 million.

The second section, B-1, connecting Coari and Anamã is still in the final phase of negotiation, following the cancellation of the tender bid due to an excessively high price. In this case, neither the main contractor nor the price have yet been established. The Anamã-Manaus stretch of the gas pipeline is to be built by the Camargo Correa/Skanska Consortium at a cost of about R$ 428 million.

The works are being financed by Banco Nacional de Desenviolvimento Econômico e Social (BNDES) through a structure which includes Transportadora Urucu Manaus S/A, a special purpose company that is responsible for both projects.

In addition to the economic advantages, the substitution of existing fuels by natural gas will represent an enormous environmental gain for the Country. Production of electric energy from natural gas significantly reduces emissions of polluting gases, especially carbon dioxide (CO2), thus contributing to a reduction in the greenhouse effect in line with the Kyoto Protocol, to which Brazil is a signatory.
