Route 3 final phase of commissioning and testing of the onshore and shallow sections scheduled for the beginning of the second half of this year

(PN) One of the great expectations of the Brazilian oil and gas sector this year is the entry into operation of the Route 3 gas pipeline, which will transport gas from the pre-salt layer to the coast. In preparation to finally put the asset into operation, Petrobras informed Petronotícias that the final phase of commissioning and testing of the onshore and shallow sections is scheduled for the beginning of the second half of this year. The Route 3 Gas Pipeline has a total length of approximately 355 km, of which 307 km are offshore and 48 km are on land.

At the beginning of the year, the oil company had already started the operation of the deep section of the gas pipeline. Meanwhile, the company is also working on the last activity of the shallow water section, which aims to make the interconnection of spool 2 to connect the shallow and deep sections in a water depth of 58 m. The works on the land stretch from the beach to the Gaslub Hub have already been completed.

The deep stretch of Route 3 is 297 km long, between water depths of 58 meters and 2,190 meters in depth. The shallow water part starts at a depth of 58 meters, with 10 km in length. When operational, the flow from Route 3 will be approximately 18 million m³ of gas per day.

The gas that will be drained through Route 3 will be treated at the Natural Gas Processing Unit at the Gaslub Hub. The project will have the capacity to drain and process 21 million cubic meters per day of natural gas from the pre-salt pole of the Santos Basin. Together, Route 3 and Routes 1 ( Caraguatatuba/SP) and 2 (Cabiúnas/RJ) – the last two already in operation – will provide a total capacity to flow 44 million cubic meters of gas per day.

The entry of natural gas into the GasLub Hub will take place through the Guapimirim-Comperj I (Gaserj) gas pipeline and enable the start of operations of the utility systems, mainly in the Steam Generation and Distribution Unit. These systems will guarantee the supply of the facilities and equipment necessary for the start-up the Natural Gas Processing Unit, scheduled for later this year.

In addition to the units that are entering the testing phase include: the water treatment plant, the substations responsible for the distribution of electric energy for the enterprise, the Integrated Control Center (CIC), the auxiliary utilities systems and the ‘ flare’ (residual gases).
