Protecting your assets, from first deployment to life extension

Know the condition of your subsea asset before it's too late

Unplanned subsea asset interventions can be complex and expensive. Asset integrity monitoring in deepwater doesn’t have to be challenging and dangerous. We provide you continuous, real-time insight into the health of your assets. As a result, confident decisions can be made, reduce offshore intervention and unplanned downtime to keep operations running smoothly.

Our monitoring systems deliver continuous insights on asset integrity, on demand, so you can act on evidence, not assumptions.

Subsea asset integrity monitoring challenges

Every asset type, one monitoring system

The integrity risk of a subsea asset develops according to how it is loaded and operated.

A riser can accumulate fatigue through continuous cyclic loading and vortex-induced vibration. A mooring line can be exposed to excessive tension or uneven load distribution. A pipeline can gradually walk across the seabed, increasing the loading and tension acting on it. A wellhead can accumulate fatigue from drilling operations, layered on top of long-term production loads.

The warning signs are different for every asset and so is the data needed to identify them.

A generic sensor package can tell you that something has changed. It takes an asset-focused monitoring approach to understand whether that change matters.

Our monitoring systems are configured around the behaviour, loading and integrity risks of each asset. We identify the failure mechanisms that matter, the parameters that reveal them, and the data needed to provide meaningful warning.

That could mean detecting changes in movement or vibration, tracking load and tension, monitoring fatigue accumulation, or confirming that an asset remains within its expected operating envelope.

The result is actionable insight, giving you the information to schedule an inspection when it is needed, adjust operating conditions, investigate a developing issue, or confidently stand down an intervention when the data shows the asset remains within safe limits.

That’s the difference between monitoring an asset and understanding its’ performance.

Change what's possible for long-term deepwater asset integrity monitoring

Long-term deployment. 3, 5 and 10-year capability

Observer is our intelligent subsea asset integrity monitoring solution, designed for long-term deployment. Now years of continuous monitoring without intervention are possible. It transforms deepwater structural health monitoring, replacing the risk and cost of repeated mobilisations with one deployment and continuous, long-term real-time insight.

 

Onboard edge processing

Observer processes data and reports what that matters to you and your project. Standard measurements like angle, PSD and statistics are available out the box, fatigue calculations and small raw data sets are transmitted. The end result is fast actionable insight delivered without the need for a dedicated vessel to intervene.

 

Flexible data retrieval via vessel, USV or AUV

Retrieve your monitoring data the way that suits your operation, use a crewed vessel or a vessel of opportunity. Or even an uncrewed surface vehicle (USV) to minimise personnel on board or an autonomous underwater vehicle (AUV). Whichever route you choose, data comes back reliably, giving you the freedom to match data retrieval to budget, weather window, or operational risk.

In report locations a gateway buoy can provide a means to have on demand access to your data, these can be installed where there is no existing surface infrastructure or where vessel access is costly or impractical.

 

Trusted acoustic communications

Our acoustic communications protocol, Wideband 2, maintains reliable data links near infrastructure and in noisy environments. Critical for asset integrity monitoring close to topside assets so your data isn’t compromised.

Riser integrity monitoring

Manage SCRs, TTRs, hybrid risers and SLWRs, with continuous fatigue accumulation and VIV detection along the riser length measure acceleration, angular rates and strain. Its also possible to include USBL positioning to manage the global movement of the riser.

Mooring line monitoring

Real-time tension and angle monitoring, with early detection of line elongation and asymmetric loading.

Pipeline and flowline integrity

Settlement, tilt, FIV and structural health data supporting shutdowns and long term asset management.

Jumper and spool piece monitoring

Settlement, tilt and structural health data feeding directly into integrity management software.

Wellhead monitoring

Fatigue life estimation for wellheads during drilling or long-term production load. Monitoring and maintaining safe operation of the drilling string.

Observer

Observer has been developed specifically for monitoring moorings, flowlines, risers, umbilicals, pipelines and structures. It provides operators insight into integrity and early warnings, replacing guesswork with continuous, real-time data. Its onboard processor analyses data at source supporting long-term deployments, cutting offshore intervention and giving you confidence to act on real information.

Acoustic Data Logger

Acoustic Data Loggers are for operators monitoring subsurface performance to improve the understanding of well characteristics, it improve efficiency and reduce vessel time offshore, it replaces the guesswork with continuous downhole data. Built on 30 years of field-proven performance, it records multiple gauge readings at set intervals, storing and then transmitting data acoustically for when your vessel is back in the field and ready to download.

Fetch

Fetch is there for the long term, helping operators monitor seabed movement over very long durations, identifying changes in the overburden leading to subsidence before it threatens asset integrity. Fetch captures pressure, temperature and inclination data, which is retrieved acoustically by a vessel, USV or AUV. Allowing operators to gain long term data on behavioural changes from increases in rock stresses allowing them to balance and manage reservoir pressures.

Detect change. Decide sooner.

From seabed subsidence to structural movement, our integrity monitoring systems give you a continuous, through-life view of subsea asset health. That means less intervention, longer field life and operations that stay on schedule. Proven acoustic technology delivers reliable data from the seabed to your control room, whatever the water depth.
