We support our global clients across the complete life cycle of offshore decommissioning programmes, from strategic planning to execution. Our experts employ systems engineering principles, advanced analytical skills and unique modelling techniques to help our clients de-risk their complex multidisciplinary activities.

Subsea risers and flowlines

With a detailed knowledge and understanding of subsea risers and flowlines, we help clients optimise the design and performance of these complex systems, ensuring capital and operational costs can be minimised without compromising safety requirements.

Delivering expertise in dynamic subsea systems

Through supporting clients in the design, assessment and analysis of their pipeline assets, we help ensure they remain safe through their lifespan. Our systems engineering approach delivers understanding of the complex multiple interfaces that influence the performance of subsea risers and flowlines.

Mechanical and structural integrity

Ageing assets, life extension and an ever-greater focus on essential safety requirements means the level of effort to deliver cost-effective, safe operation and to avoid costly downtime is increasing.

Frazer-Nash is at the forefront of advanced techniques to solve complex engineering problems experienced by a range of material types, including metallic and non-metallic. Our methods can be used to assess the integrity, performance and future life of plant, structures and mechanical systems with confidence.
