Whether part of a fixed platform, floating installation, tie-back system, or standalone development, subsea assets and infrastructure are fundamental to any offshore production system. From wellheads, umbilicals, pipelines, risers, and flowlines to their supporting structures, foundations, and anchors, these systems are highly sophisticated and operate in extreme, hard-to-access environments where reliability is critical.
At LR Energies, we help owners, operators, EPC contractors, and their supply chains manage technical and operational risk, ensure compliance, and enhance reliability across subsea systems and offshore equipment. From initial design and engineering verification to the inspection of hardware that underpins safe production, we help you navigate the unique challenges of the subsea sector.

Driving Subsea Standards and Innovation
As the industry moves into deeper and more remote waters, subsea engineering is advancing rapidly and becoming increasingly critical to success. Through Joint Industry Projects and research in subsea processing, remote inspection, and deepwater technologies, we keep clients at the forefront of innovation. Our experts are leaders in the subsea industry, actively contributing to committees and working groups that develop and maintain critical standards such as API 17J, API 17B, IEC standards, PD8010-2, and other guidelines across offshore, renewable, and process disciplines.
Beyond shaping standards, our specialists share their knowledge globally, presenting at industry conferences, publishing technical insights, and driving innovation in subsea engineering, including:
- OMAE 2023 – Upheaval Buckling Analysis of the Large Deformation of Unbonded Flexible Pipe under Cyclic Pressure and Temperature Loadings
- OTC 2023 – Upheaval Buckling of Unbonded Flexibles Pipes – An Alternative Approach
- SPT 2024 – Balancing Act: Navigating Residual Lay Tension in Subsea Pipelines Design
- OMAE 2025 - A Fracture Mechanics Study on Pressure Armour Wire in Flexible Pipes.
