A non-intrusive unit that detects all types of PIG and indicates debris removal in cleaning operations
The Roxar PDS is a non-intrusive pipeline integrity management (PIM) tool that doesn't require mechanical modifications. The unit detects all type of PIG, such as scraper, cleaning or batching PIG, and enables operators to understand the performance of their pigging operation. The detector is compact, low weight and can provide easy-to-use data directly to DCS or SCADA systems.
The Roxar PDS system consists of the following parts:
When a PIG travels through a pipe, the friction between the PIG and the
pipe will generate a characteristic sound signature. This signature is processed by the unit's algorithm to accurately detect when the PIG has effectively passed. The PIG shall travel at a minimum velocity of 0.05 m/s.
The data from the acoustic sensors can be sent directly from the Calculation Interface Unit (CIU) to DCS or SCADA systems by digital or analogue IO without having to connect to a PC. Another way to configure, extract and analyse information from the sensors is by using the Roxar service software which is part of every delivery of a Roxar PIG detector. The CIU software is an .exe file which makes a direct connection from a windows based computer to the CIU.
The Calculation & Interface Unit (CIU) is the data handling module of the acoustic sensor. It receives the information from the detector and outputs the engineering values.
The CIU has several communication interface options, both digital and analogue. Each CIU features 8 LED indicators, showing the present operational status.
