Design choices ‘make or break’ subsea pipeline integrity, finds LR study for Havtil

Early-stage design and qualification decisions play a critical role in determining the long-term integrity of subsea pipelines, according to new research commissioned by the Norwegian Ocean Industry Authority. The study, conducted by Lloyd’s Register, emphasizes the importance of robust design and qualification of subsea connectors.

These components are vital for connecting offshore production fields to processing and export facilities, operating in some of the world’s harshest environments. The report highlights that the design stage directly impacts the risk of failure throughout an asset’s service life. With Norway ramping up offshore exploration, including 70 new blocks in the APA 2026 licensing round, regulators are intensifying their focus on the structural safety of pipelines and subsea facilities.

The study supports Havtil’s risk-based approach, underscoring the necessity for operators to ensure robust connector design and qualification processes. Comprehensive qualification offers confidence in connector integrity throughout service life, while early involvement of the original equipment manufacturer can aid in extending the asset’s operational life by validating design assumptions and performance limits.

Sean Murray, Global Technical Authority for Pipelines and Subsea at Lloyd’s Register, stated that subsea systems must perform safely and reliably in challenging conditions, and design choices significantly influence their integrity. The project consolidates industry experience and operational data to enhance risk-based decision-making for subsea assets.

Havtil, which prioritizes structural safety, values the technical insights provided by Lloyd’s Register, offering operators a clearer evidence base for design and integrity decisions in complex offshore developments.
