Rosenxt expands subsea inspection capabilities to support confident integrity decisions

Subsea assets operate in demanding environments where integrity can be difficult to establish, and decisions can carry long-term consequences. For operators, inspection is not simply about collecting information below the waterline. It is about gaining the insight needed to manage integrity, plan interventions, and make confident decisions throughout an asset’s life.

Rosenxt is expanding its subsea capabilities with inspection services for subsea assets. Rosenxt Subsea brings together autonomous subsea technology and expertise developed over decades in pipeline integrity and engineering, supporting customers from early scope definition through to inspection delivery, data interpretation and reporting.

“Building on an impressive asset integrity history, combined with recent strategic transactions that bring expert knowledge, experience and technology together, we are excited to bring a forward-looking option to the market.” said Joe Tidball, Venture Manager at Rosenxt Subsea Structures.  

Inspection designed around the decision

Every subsea inspection programe begins with a question. An operator may need to understand current asset conditions, investigate a potential change, support an integrity assessment, or plan an intervention.

Rosenxt’s approach is to support the definition of required information first, then design an inspection scope around that need. This helps ensure the results are relevant, accurate and repeatable, rather than producing data that is difficult to interpret or use.

By connecting inspection results with integrity assessment and planning, the focus moves beyond individual survey outputs. Condition information can support decisions on safety, asset life, intervention timing and longer-term integrity management.

From subsea data to informed action

The value of subsea inspection lies in what happens after the data is collected.

Rosenxt provides end-to-end support throughout the project lifecycle to create a structured route from subsea condition information to clear, usable integrity insight.

The approach is designed to help operators:

• Gain a clearer understanding of subsea asset condition.
• Access accurate, repeatable datasets that can support comparison over time.
• Identify potential changes and prioritize areas for further assessment.
• Support integrity assessment, intervention planning and asset-life decisions.
• Work with a single team across the inspection and interpretation process.

Built on integrity and subsea expertise

Rosenxt Subsea brings together autonomous subsea technology and expertise developed over decades in pipeline integrity and engineering. This capability has been strengthened through strategic technology acquisitions, including K.U.M. and Zupt.

The result is a combination of subsea technology, inspection, monitoring, data and operational expertise. The objective is straightforward: to provide customers with the information they need to understand asset conditions and make informed decisions.

Rosenxt’s approach is not based on applying the same system to every requirement. Inspection scopes are shaped around the customer’s asset, operating context and information need, using the most appropriate combination of technology and operational delivery.

Supporting subsea asset integrity

The offering is designed to support operators of subsea assets across offshore energy and other demanding environments where accurate condition information is essential to safe, reliable operation.

Rosenxt works with customers to understand the integrity questions they need to answer, whether that relates to current asset conditions, potential change over time, intervention planning, or longer-term asset-life decisions.

By providing accurate, repeatable inspection information and connecting it with engineering interpretation, Rosenxt helps customers reduce uncertainty and make decisions based on evidence rather than assumption.

This outcome-led approach can be applied across a range of subsea assets and operating contexts, with the inspection scope shaped around each project’s specific requirements.
