Risk Based Inspection (RBI)

Risk Based Inspection is a procedure used for designing optimised inspection plans based on knowledge of the risk of failure. The RBI process is predominantly utilised by the industry for the examination of equipment such as pipelines, industrial plants, pressure vessels and heat exchangers. It allows for the development of an optimal inspection strategy for reliability, availability and provides assurance that assets can operate safely. Web-based RBI software means users find it easier to access the application without the need to install it on their laptop. Web-based RBI software can be easily integrated with the SAP system and can also display a summary of RBI assessment results in the form of a dashboard. In addition, top management can monitor risk assets through the RBI dashboard.

TWI develops desktop and web-based RBI software for process plant and pipelines in accordance with applicable standards such as API RP 580, API RP 581 and TWI’s proprietary procedures. The web-based RBI software is developed according to client needs, which can be integrated with SAP and can also display a summary of the RBI assessment results in the form of a dashboard. Every asset change in SAP will automatically update asset data in the RBI software.
