This new training course provides a wide-ranging overview of all aspects of pigging operations. It is held at the CTDUT facility adjacent to Petrobras’ Duque de Caxias refinery, near Rio de Janeiro, and will use the recently-inaugurated 14-in, 120m long, water- and nitrogen-driven test loop at the site, but from 2010 the course will be adapted to use the 2.5-km long 12-in crude oil and 16-in gas test loops which are currently under construction.
The syllabus includes both hands-on exercises using the test loop(s), as well as classroom instruction, and full documentation. The content of the course has been developed jointly by Penspen, PipeWay, and Clarion/Scientific Surveys Ltd. PipeWay, through its Rio de Janeiro office, has agreed to provide cleaning-, geometry-, and intelligent tools for use during the course, along with its expert technicians. Among subjects that the syllabus will cover are:

Who should attend:Engineers and technical personnel involved in field pigging operations. |
Course NotesThe classroom portions of the course will be fully documented with all slides and related documents printed in a durable 3-ring binder for reference during and after the course. Continuing EducationOn completion of the course, participants will be eligible to receive 3.0 Continuing Education Units (CEU’s). |
