PERMiT – Pipeline Erosion Risk Mitigation Toolkit

Reduce erosion risk while optimizing production

• PERMiT is a unique tool designed to predict and mitigate erosion risk. It helps with design and operation of oil and gas pipelines within acceptable erosion limits.

• Designers can size pipelines and recommend operating envelopes to stay within the erosion limits.

• Field operators can optimize production rates to stay within erosion limits when production scenarios change. It ensures safe and reliable operation of pipelines.

An integrated tool kit that enables Pipeline Integrity

teams to analyze and manage erosion using data

science, erosion science and CFD models.

Key Features:

• Comprehensive suite of erosion models (API, DNV, Salama, Salama-

Venkatesh, Jordan, and ECRC).

• Comparison of model data with lab and / or field data

• Automatic parametric analysis to rapidly determine operating

envelope (for e.g. velocity boundary plots, sensitivity plots and

operating envelope curves)

• CFD module to enable CFD analysis of piping components

• Data science module to facilitate development of data driven models

Erosion Model Calculations

• Prediction and comparison of erosion rates using

various erosion models for piping components such as

elbows, tees, welded joints, straight pipes, and reducers

• Erosion models available in PERMiT: API RP 14 E, DNV

RP 0501, Salama, Salama & Venkatesh, Jordan – ECRC,

ECRC –Bubble flow

• Construct erosion velocity boundary plots using

different models

• Allows user to superimpose operating envelope curves

generated using different models for comparison

• Create sensitivity plots to see how erosion is affected

by changes to a parameter such as gas velocity or pipe

diameter

• Store wall thickness, coupon data, or

erosion rates along with all relevant piping

configuration, process flow conditions, etc.

• Customizable database with ability to

integrate and streamline entire process

from end to end

• Built-in database of published experimental

data available

• Ability to filter databases for experimental

data relevant to present case

• Ability to compare experimental data to

erosion model results

Experimental Data Module

• Fully automated module that allows design and operations

engineers to create CFD models and analyze their pipelines

• Automated geometry creation

• Fully automated mesh generation

• Pre-optimized meshing algorithm which create

unstructured mesh for the complete domain

• Combination of hexahedral and polyhydric cells

• Appropriate refinement of mesh near impeller to capture

higher velocity gradients

• Choice between two turbulence models and two erosion

models

• Ability to model sand particles as constant diameter or Rosin-

Rammler size distribution

• Automated post-processing

• Contour plots of erosion and velocity

• Vector plots

• Path lines plots

DATAe – Data Driven Models

• Ability to import field data, clean the data,

visualize the data in various ways, and

create data-driven models

• Automated process of choosing which

variables in dataset are most significant

• Ability to create several data-driven models

and choose the ones that fit the data best

• Ability to use model for predicting erosion

rate, similar to published models used in
