The welding engineer of Chen Welding Integrity (CWI) Services was engaged by McDermott to provide welding quality assurance support for Total’s Tyra Redevelopment Project. The welding quality assurance support was performed by the welding engineer with Certified International Welding Engineer qualification and international project experience. The welding engineer of CWI Services was seconded to McDermott’s procurement quality department of Tyra Project for 13 months to provide the required support.
The scope of support under the welding quality assurance support included welding document review and technical advisory support to the project team. The technical advisory support included compliance advice for project specification and international codes, liaison and propose of solution to Total and vendor for resolving incompliance and technical issues. The scope of support also included provide guidance to the project quality team in resolving issues related to compliance of ISO 3834 requirements and develop an audit checklist as a reference and guideline for vendor audit.
The welding quality assurance support provided by the welding engineer of CWI Services has assisted McDermott procurement quality team completed review of more than 1000 documents for more 100 packages within the review cycle period and resolved technical issues by meeting the requirements of MOTS, PED, McDermott technical specification and international codes.
The theoretical knowledge, practical experience and competency of the welding engineer were the primary contributing factors for the welding engineer to complete the support in quality and efficient manner without impacting the project progress.

CWI Services completed a material selection study for hyrdopower dam for a design company from Sichuan China. The material selection study was carried out to analyse the feasibility of using alternative metallic material for dam surface to replace the concrete material. The study was initiated by the hydropower plant owner and contracted to CWI Services via the design company Sichuan Tongxingyuan.
In the design process, TXY considered to use reinforced concrete to construct the entire dam. However, there are challenges to construct upstream dam side for retaining water with reinforced concrete due to the possibility of concrete cracking during the hydration process. Also, reinforced concrete also has inadequate tensile strength to withstand the service loads and prevent cracking in the case of dam movement is happened. Furthermore, construction cost of using reinforced concrete is also not economic. Therefore, the TXY considered to design the upstream dam side with alternative metallic surfaced material to cover the upstream dam surface.
CWI Services carried out a material selection study to study the feasibility of metallic material as dam surfaced material. The material selection study by applying the approach as follows:
The overview of this material selection study process and the result are illustrated graphically in picture as attached.
Throughout the systematic and scientific material selection study carried out CWI Services, TXY obtain information with respect to candidate metallic materials to propose the design ideas to PNG Hydro Development Limited.
CWI Services is capable to carry out material selection study from various perspectives to ensure the comprehensiveness and appropriateness of material application.

Inspection and testing are essential to ensure welded product complying with project specification and code requirements. The international welding quality management standard, ISO 3834 also has specific requirements for the execution of inspection and testing activities as well as quality record control requirements to record, document and retain the quality records. Inspection and test plan is a commonly and widely used by fabricators to plan and monitor the execution of inspection and testing activities and record the summary results of inspection and testing for achieving compliance of ISO 3834 requirements.
In view of the importance and wide application of inspection and testing in ensuring the quality of welded products, CWI Services produced the first video compiling the actions of inspection and testing activities for welding fabrication. The videos and photos used in the video were collected by CWI Services throughout the years.
The video aims present the actions of execution for welding fabrication inspection and testing and provide the concept in planning inspection and testing. This video also can be used for education purpose to ensure inspection and testing can be planned and executed to compliance with the quality requirements of project specification and codes e.g construction code and quality management system (ISO 3834).
The video clip attached is a preview for the full version welding fabrication inspection and testing.

Sinopec International Petroleum Service (Thailand) Co. Ltd (Sinopec) is the contractor for a 42-inch Pipeline in Thailand. Sinopec applied automatic GMAW and semi-automatic FCAW processes to weld the circumferential seam welds between line pipes. The weldments were required to comply with the welding requirements of API 1104 and sour service hardness requirements of ISO 15156-1. Figure 1 shows an area of pipeline welded with automatic GMAW process.
Chen Welding Integrity (CWI) Services was engaged by the Sinopec as an independent expert to carry out a welding compliance surveillance to ensure the welding comply with the requirements of project specification, qualification and construction codes, welding procedure and welding practices. The compliance surveillance from Sinopec was followed by a series of technical support provided to Sinopec by their certified international welding engineer (CertIWE).
