LNG & Gas Processing
Cryogenic Materials, Welding & LNG Asset Integrity
A three-day programme for welding, inspection and integrity engineers working on LNG service equipment — material selection, 9% nickel and austenitic welding control, toughness testing, NDT and in-service inspection of cryogenic assets.
Industry focus: Fabrication, Welding & Heavy Engineering
Who Should Attend
Designed for these roles
- Welding, QA/QC and inspection engineers on LNG tanks, piping and modules
- Integrity and mechanical engineers responsible for cryogenic assets
- Fabrication yard engineers bidding or executing LNG service scopes
- Project engineers reviewing cryogenic material and welding submissions
Delivery formats
- Customised in-house training at your plant or office
- Public classroom delivery, subject to schedule
- Live online delivery where suitable
- Recommended group size: 8–20 participants
Problems Solved
What this course fixes
Cryogenic welding treated as ordinary carbon steel work until the impact tests fail
Repair rates and rework costs on 9% nickel and stainless work eroding margin
Inspection plans for cold service equipment copied from ambient service assets
Cold spots, insulation damage and external corrosion under insulation missed until failure
Learning Outcomes
What participants can do after the programme
Outcomes are written as tasks, not topics — so managers can verify capability back at work.
- Select materials for LNG service against toughness and code requirements
- Control welding of 9% nickel steel, austenitic stainless and aluminium alloys
- Specify and interpret impact, ferrite and cryogenic qualification testing
- Plan NDT for cold service welds and interpret results against acceptance criteria
- Build an in-service inspection strategy for tanks, cold boxes and cryogenic piping
Course Outline
Detailed programme content
Day 1 — Materials for Cryogenic Service
- Low temperature behaviour: toughness, transition temperature and brittle fracture
- 9% nickel steel, austenitic stainless steels, aluminium alloys and Invar
- Code and standard requirements: ASME, EN 14620, API 625 and API 620 context
- Insulation systems, cold spots and corrosion under insulation in humid climates
Day 2 — Welding & Qualification Control
- Consumable selection and dilution control for 9% nickel and stainless welds
- Heat input, interpass control, magnetism issues and distortion management
- PQR and WPS essential variables for low temperature service under ASME IX
- Impact testing, ferrite measurement and hardness requirements
- Exercise: review a cryogenic PQR package and identify the gaps
Day 3 — NDT, Inspection & Integrity Management
- NDT method selection for cryogenic welds and thin austenitic sections
- Tank construction inspection, hydrotest, cooldown monitoring and settlement
- In-service inspection of tanks, cold boxes, vaporisers and cryogenic piping
- Damage mechanisms specific to LNG assets and their inspection response
- Workshop: draft an inspection plan for an ageing LNG storage and piping system
Practical Work
Practical exercises and case studies
Sessions are built around calculations, data interpretation and technical decisions. Case material is generic or anonymised — no client-confidential project data is used.
Material selection exercise against minimum design metal temperature requirements
Review of a cryogenic PQR package to find unsupported essential variables
Impact test and ferrite result interpretation against acceptance criteria
Inspection plan drafting for an ageing LNG tank and cryogenic piping circuit
Trainer Profile
Delivered by Azman Yusof
Senior Trainer — Welding, NDT & QA/QC
18 years industry experience
Azman has qualified hundreds of welding procedures and rejected plenty of them. His sessions run on real radiographs, real PQR packages and real client NCRs, so participants leave able to defend a weld package in front of a client inspector.
Real project exposure
- WPS/PQR qualification programme for an offshore jacket fabrication yard in Lumut
- Weld repair rate reduction programme at a structural fabrication shop in Pasir Gudang
- Third-party QA/QC oversight for pipeline tie-ins in Terengganu
Certifications
- CSWIP 3.1 Welding Inspector
- ASNT NDT Level III (UT, RT, MT, PT)
- IWE — International Welding Engineer
Trainer allocation is confirmed in your proposal. Substitute trainers hold equivalent certification and sector experience.
