Asset Management and Inspection

Judicious asset management is paramount to having safe, efficient, reliable, long lasting equipment which remains cost effective.  Having appropriate inspection and maintenance schedules in place for primary and ancillary equipment based on historic data and characteristics of the plant forms the cornerstone of achieving these objectives.  Re-Generate understand these needs and can assist with the creation, maintenance and inspection of key assets based on:

  • Historic Data

  • Characteristics of the plant

  • AS 3873 "Pressure Equipment - Operations and Maintenance"

  • AS/NZS 3788 "Pressure Equipment - In-Service Inspection"

  • API RP581 "Risk_Based Inspection Technology"

  • Additional internationally accepted and appropriate codes

Non-Destructive Testing (NDT)

During inspection it is often necessary to employ Non-Destructive Testing (NDT) techniques to inspect for damage.

 

Re-Generate have a range of NDT methods available to assist or manage onsite inspections including:

  • Magnetic Particle

  • Phased Array Ultrasonic Testing

  • Dye Penetrant

  • Hardness Testing

  • Chemical Analysis

  • A range of Metallography techniques

Fitness-for-Service (FFS) Assessments

When any form of damage is identified in equipment the questions often center around the steps required for a return to purpose: Does it need to be replaced, repaired, or is the extent of damage to the equipment within parameters to be considered as still fit for purpose and fit for service (and how long can it remain in service in the damaged state).

​

Fitness-for-Service assessments answer these questions and can address the following damage:

  • Brittle Fracture

  • General Metal Loss

  • Local Metal Loss

  • Pitting Corrosion

  • Blistering & HIC/SOHIC

  • Weld Misalignment and Distortion

  • Cracks and Crack Propagation

  • Creep

  • Fire Damage

  • Dents, Gouges

  • Laminations

  • Fatigue

​

Re-Generate have staff with 12+ years experience performing FFS assessments to a range of internationally accepted codes based upon the equipment, industry, country and specific client requirements.  These include:

  • API 579-1:2016

  • BS7910:2013

  • FITNET FFS

  • British Energy's R5 Code

​

Finite Element Analysis (FEA)

Finite Element Analysis (FEA) is an invaluable engineering tool for numerous types of analysis on complex geometry including:

  • Stress Analysis

  • Crack Growth Analysis

  • Natural Frequency and Eigen Model Analysis

  • Vibration & Acoustic Analysis

The results of a FEA are often a necessary input for a Fitness-for-Service assessment.

 

Re-Generate have staff with 18+ years experience performing FEA in a range of packages including:

  • Abaqus

  • Algor/FEMAP

  • Ansys

  • Nastran/Patran

  • Solidworks Simulation/COSMOS

  • Warp3D

Computational Fluid Mechanics (CFD)

Computational Fluid Mechanics (CFD) continues to grow in use within the Hydro power industry and many others, with utilization seeing improvements in understanding the accuracy of:

  • Flow conditions

  • Pressure

  • Velocities

  • Temperatures

  • Reaction Forces & Moments.

 

This ultimately reduces the risk associated with design, modifications or repairs to critical assets by reducing the number of assumptions and oversimplifications typically required in fluid flow calculations.

​

The results of CFD are often necessary inputs of Finite Element Analysis and Fitness-for-Service assessments.  Re-Generate have staff with many years experience performing CFD in a range of packages including:

  • Ansys/FLUENT

  • OpenFOAM
