Pipeline Crossing
Similarly, the onshore pipelines are also dissected into smaller sections to understand and classify them based on its properties and effects over kilometres of pipeline over land and underground.

GALIOM allows pipelines operators to plan preventative maintenance time based and condition based through its PM planning module. GALIOM allows engineers to prepare and track the work scope until completion. The collected pipeline data like intelligent pigging data is uploaded into GALIOM which plots graphs to demonstrate the flaws in pipeline. The flaws are further reported and tracked through its inspection reporting module which also assists with fitness for purpose analysis. GALIOM calculates ERF using various approaches like ASME B31G, RSTRENG, KASTNER and SHANNON.
Risk Based Inspection approach for Pipeline
GALIOM for Pipelines derives consequence of failure by applying the environment impact, people safety, economical consequence and reputation and political consequences and on other hand probability of failure is applied using 3rd party impact, corrosion, design, operations and remaining life parameters. Using CoF and PoF over a risk matrix comes up with the risk zone. Based on the remaining life derived and risk zone GALIOM comes up with a next due date for respective monitoring types.
CoF and PoF produced risk matrix
The main reasons for implementing a risk based approach in inspection planning are:
- To ensure that the "Base Line Risk" does not exceed the risk acceptance criteria, as set by the operator, at any time
- To focus the inspection effort on items where the safety, economic or environmental risks are identified as being high, whilst similarly reducing the effort applied to low-risk systems
- To identify the optimum inspection or monitoring methods to match the identified degradation mechanisms
