DUCTS COMISSIONING

This activity has been developed based on the National Oil Agency’s (ANP) policy number 170 dated November 26, 1998. This policy states that all new ducts for liquefied petroleum gas (LPG), natural gas (NG), and flammable and combustible liquids, must be subject to evaluation by independent companies, to obtain the commissioning certificate.

This certificate is issued after the following documents are checked and approved:
• Duct project
• Specifications mentioned in the project and in the assembly and inspection procedures
• Procedures utilized
• Legal documentation (environmental license, firefighter’s inspection, construction
  authorization, etc)
• Operation and Maintenance Manual

Upon completion of the above steps, a check list form called “Diagnosis for issuing Commissioning Certificates” is filled in, consisting of several questions including project, operations, inspection, environmental protection, maintenance and safety system.
This certificate can be issued with some incomplete answers although definite dates for completion have to be indicated, according to the agreement between the Operator (responsible for the duct operation) and the technical licensed company (the company authorized by ANP) for issuing the commissioning certificate.

• Quality Assurance System Manual
• Data Book

 
HYDROSTATIC TESTING CERTIFICATION

This activity has been performed in compliance with PETROBRÁS – Petróleo Brasileiro S/A request to assure that the services they provide be certified by an independent company, and that the procedures and testing results be in accordance with regulations.

This certification is based on the following stages:
• Verification of the duct project
• Checking the regulations mentioned in the project
• Procedures examination
• Recording and calibrating the equipment to be used
• Follow-up of pressurization stages
• Certification of the duct tightness and integrity
• Issuing of certification report

This work is done in continuous regime and the results obtained are automatically recorded in graphic through temperature and pressure sensors. These graphics are signed by the testing operator, by PETROBRAS and by the certifying agent, being afterwards filed by PETROBRÁS, together with the duct documentation.
