flexible riser damage

Subsea Incident Engineering

Rapid response engineering assessments of riser and subsea equipment to identify and mitigate failure issues while minimising downtime and maintaining operational safety.

Our multi-disciplinary engineering and field service personnel and in-depth equipment knowledge enable us to provide integrity engineering services for all types of riser and subsea systems used in production, export, drilling, completion, and intervention operations.

We perform forensic engineering in the event of failure incidents to identify root causes, recommend design modifications and deliver remedial solutions. Common field problems or anomalies can include degradation of the riser pipe, coatings or seals, component failures, and leaks due to excessive loading or corrosion. We offer turnkey design and delivery of integrity mitigation solutions using an agile and flexible supply chain cultivated over many years of integrity remediation projects.

We have an extensive track record in integrity engineering that allows us to perform assessments and deliver on remedial solutions for complex offshore systems under extreme deadlines.
