Welding, materials and corrosion support to the oil, gas and renewable energy sectors.

Large-diameter steel line pipe

01

Materials Selection

We can provide professional advice in the following areas:

  1. Reduce life cycle costs by accurately determining the correct materials selection and corrosion control for Subsea, Topside, Carbon Capture systems.
  2. Identification of corrosion and other degradation mechanisms. Evaluation of its significance by a detailed review of process and environmental parameters through design life.
  3. Advice on appropriate precautions to avoid materials/corrosion failure by applying cost-effective materials and corrosion control.

Welding Engineering

A major part of our work has been welding engineering and the implementation of appropriate welding technology to meet specific code and process requirements.

  • Qualifying welding procedures using mechanised GTAW/PGMAW/GSFCAW welding systems to achieve fast cycle times and high-quality welds.
  • Qualification programmes for both ECA (Engineering Critical Assessments) and AUT (Automated Ultrasonic Testing) where installation by reeling is required.

03

Corrosion Engineering

We can provide professional advice in the following areas:

Corroded steel surface
  1. Conduct CO2 corrosion assessments as part of topside/subsea materials selection programme.
  2. Apply life cycle costing to ensure most suitable materials are used with appropriate corrosion control.
  3. Identification of corrosion and degradation mechanisms and their impact throughout design life based on process and environmental parameters.

04

Failure Investigation

We can provide professional advice in the following areas:

01

Identification of Failure Mechanism

02

Root Cause Analysis

Of conditions leading to failure.

03

Remedial Action

To prevent future occurrence.
