After gasification and start of operation of the RPBC delivery and receipt point, NTS prepared the new Cubatão II Delivery Point (PE) for its gasification. The actions were discussed by the field and office team, and with our client Petrobras.

But after all, do you know what this preparation consists of? We invite the responsible team to present the steps that precede the start of operation of a Delivery Point. Here's what they have to say:

The first step was planning: to set goals, predict and neutralize undesirable effects before they materialize. For this, it was necessary and fundamental the participation of all those involved, through comments, suggestions and information". “A procedure is first and foremost a dynamic tool, which must be perfected until the eve of its use, eliminating gaps”, said Homero Ancilloti, Gas Pipeline Consultant.

For Rubens Stafin, Pipeline Consultant, it is important to make work agile and safe. “We carry out detailed planning observing the PONR, to cover as many possible problems and interferences as can be encountered. In the same way as defining the sequence, measuring the time for each task in order to have a more improved control. And before starting the activities, check the necessary tools and spare parts.".

After the planning steps, the team can finally start the operational field activities, step by step, according to the reports below:

According to Márcio Azevedo, Gas Pipeline Technician, a key step was to perform the functional test of the PLC logic, as well as the communication tests between the PLC x Flow Computers x Chromatograph and the CCO Supervisory system, to meet the commissioning, in order to ensure that all communication will be operational for remote monitoring of the station.

"It was also carried out the verification of operation and calibration of all pressure and temperature transmitters, as well as the pressure gauges, thermometers and pressure switches present in the station. Making the indications of the variables more precise and reliable for the Operational Control Center - OCC and the Operator in the field.”, said João Azevedo, Gas Pipeline Technician.

"Also during the testing phase of the station for operational start, an internal inspection was carried out, according to NR-13, by the Integrity and Operation teams. In the procedure, residues (oxidation soot) were observed in the interiors of the filters and internal cleaning was carried out to guarantee the integrity of the quality of delivery of natural gas to our important customer," explained Amarildo Silva, Gas Pipeline Technician.

For the Gas Pipeline Technician, Anderson Panzica,  the biggest challenge found was the commissioning and functional testing of the gas heating system, which prevents the formation of ice in the pipeline and equipment. "We carry out the total cleaning of the equipment, drainage and replacement of the water, tests of the regulating valves, safety valves and all the automation that involves this important equipment for the delivery point".

The pressure reduction system, which consists of the most sensitive item of the installation, required the involvement of all, not only because it is the item of greatest risk, but also so that everyone knows the new equipment to be operated by NTS, in order to be prepared for a possible maintenance, whether preventive or corrective at any time of the day or night.

In summary, João Bregalda, Programming Technician at the Mauá base, concluded as follows: "Commissioning a new Delivery Point is a huge challenge, which requires a lot of preparation, testing, organization and resources. In Cubatão II, as well as in the commissioning of PE/PR RPBC, we dedicated many hours of our team from São Vicente with tests, calibrations, surveys and corrections. We involved the Mauá team and several outsourced teams, acquired materials and, on many occasions, had different activities happening in parallel. Teamwork was paramount for us to have harmony and tranquility, going through the setbacks focused on our goal: commissioning without accidents.”
