SURF Material, Welding & NDT Specialist

Project Venus Ultra-Deepwater Development

Location London, United Kingdom - Contractor's Premises

Contract Type Residential Assignment

Start Date December 2026 (Subject to Final Investment Decision - FID)

Duration 1 to 3 Years

Renewable Yes

Reporting Line SURF Technical Manager

Travel Requirements Frequent missions to fabrication yards, supplier facilities and offshore installation sites.

Role Overview

The SURF Materials, Welding & NDT Specialist Engineer is responsible for overseeing all technical activities related to material selection, corrosion, welding and Non-Destructive Testing (NDT/NDE) within the Subsea Umbilicals, Risers and Flowlines (SURF) package of the Venus ultra-deepwater development project offshore Namibia.

The position ensures the technical integrity, quality and compliance of materials, welding processes and inspection activities throughout the Engineering, Procurement, Construction and Installation (EPCI) phases.

The scope includes Steel Lazy Wave Risers (SLWR), rigid flowlines, rigid spools, rigid jumpers and associated subsea structures, incorporating carbon steel, corrosion-resistant alloy (CRA) lined pipes and duplex materials.

The Specialist Engineer acts as the technical reference for the SURF Contractor and its suppliers regarding materials engineering, corrosion management, welding qualification and advanced NDT techniques.

The position also supports the SURF Technical Manager and multidisciplinary project teams, including Subsea Production Systems (SPS), FPSO, umbilical and flexible pipe specialists.
