Lead and coordinate material selection, corrosion engineering, welding and Non-Destructive Testing (NDT) activities within the SURF package. Review, approve and manage technical documentation, specifications, drawings, procedures and engineering deliverables submitted by SURF contractors, suppliers and subcontractors. Ensure compliance with project specifications, applicable DNV codes, international standards, company procedures and quality requirements. Review and approve welding procedures (WPS), welding procedure qualification records (WPQR) and Procedure Qualification Tests (PQT), as required. Review welding qualifications, NDT procedures, inspection techniques, personnel qualifications and acceptance criteria. Provide technical oversight of carbon steel, CRA-lined pipe and duplex stainless steel materials and associated welding and fabrication processes. Review and assess corrosion protection measures, material compatibility and the suitability of materials for the project operating environment. Review detailed engineering deliverables, installation and in-place analyses, technical queries, deviations and derogation requests. Identify technical risks, design deviations, constructability issues and potential quality or safety concerns, recommending appropriate corrective actions. Support and witness qualification programmes, mechanical and laboratory testing, Factory Acceptance Tests (FAT), Extended Factory Acceptance Tests (EFAT), System Integration Tests (SIT) and other relevant testing activities. Provide technical support and surveillance during fabrication at contractor and supplier yards, including welding operations, material traceability, consumables, heat treatment and other special processes. Review and approve special processes such as induction bending, pickling, passivation and post-weld heat treatment, where applicable. Support NDT activities, including Automated Ultrasonic Testing (AUT), Phased Array Ultrasonic Testing (PAUT), Time-of-Flight Diffraction (TOFD) and other relevant inspection methods. Monitor contractor performance, technical progress, quality compliance and timely delivery of engineering and fabrication activities. Support offshore pipeline installation activities and provide technical assistance to company representatives at fabrication and offshore sites. Coordinate with SURF, SPS, FPSO, umbilical and flexible teams to manage technical interfaces and resolve cross-package issues. Support the SURF Technical Manager and Subsea Manager during tendering, technical bid evaluations, contract execution and contractor management. Ensure compliance with HSE, quality, ethics and anti-corruption requirements throughout project execution. Report technical issues, deviations and risks to project management, propose mitigation measures and contribute to lessons learned and project close-out activities.
