Depth of Burial Report
Cable Burial Risk Assessment
Our latest Depth of Burial report is a zero intervention to establish depth of burial every 10m along the cable, established via a short (typically 2-4 weeks) turnkey deployment.
We output the DOB and a graph of changes over time and partner this with observed vessel movements to tie Depth Risk to actual Vessel crossing and movements in the vicinity of the cable for a full CBRA.
A low cost, low carbon alternative to conventional vessel and ROV based approaches.
One Time Health Assurance
CPS Cable Health Survey: Short-Term Insight, Lasting Impact
Get valuable insights into the state of the cable at the critical CPS and turbine locations through our short-term turnkey diagnostic service. Over a two to four week period, our expert team deploys advanced monitoring equipment to assess your cable’s health under real-world conditions.
This streamlined version of our permanent monitoring solution delivers key performance data, requires no oversight, does not interfere with operations.
We provide the state of all the key locations: End of CPS to Touch Down Point, TDP to Aperture & Aperture to Hangoff. We provide a quantitative assessment of all the key metrics: Abrasion, Movement, Fatigue etc as well as a ranking of all the turbine locations in the windfarm on a single page. In addition we provide a delta to the previous survey.
One Time Health Assurance
Cable Joint Health
Cable joints (repairs, factory or at-sea manufactured) are always a critical location for failure monitoring.
- Is the joint overheating?
- Is it undergoing movement?
- Is it well buried?
- How well does it behave electrically?
Over a 2-4 week period we gather all the experienced behaviour on the joint, compare it to history and other joints in the field and provide a quantitative assessment of the health of the joint.
Minimal footprint approach to maximising understanding
The dip in health check may not fully experience the expected range of cable conditions.
reducing time to repair
Failure pin pointing
Transform your subsea cable repairs with cutting-edge failure detection technology.
Our rapid-response team deploys advanced Distributed Acoustic Sensing (DAS) equipment to locate cable faults with remarkable precision – within 10 meters across distances up to 200km.
A second or parallel operation with a workboat can then zone this in to a small location on the earth’s surface with tap testing.
The 10 m positional resolution is achievable anywhere along cables up to around 200 km in length.
- Repair planning time
- Cable replacement costs
- Operational downtime
Ready to minimise your cable repair costs and decrease the uncertainty on where to cut?
Did you know?
We can also report on cetacean activity, lightning, thunder & wave height – although these are more use to the operational community.
Postpone cable failure
Cable Palliative Care
Conventional approaches to failure location detection (thumping) are potentially damaging to the cable – it is not unknown for aggressive thumping measurements to result in new failures on re-energisation.
By extending monitoring for a short period we can extend health checking to a live process to assure clients of performance of other regions of the cable.
For clients with already deteriorated cables they will be faced with the choice of heading in to failure and waiting for a repair window. Health monitoring can provide an alternative where medium term monitoring can act as a feedback loop where the electrical and physical condition of the cable is monitored as a function of throughput to act as a throttling mechanism enabling maximum tolerable power to be carried on the cable without it leading to failure. This can help a cable limp through until a pre-emptive repair can be carried out in benign summer conditions.
Benefits of Cable Health Monitoring
As hardware agnostic, experts in fibre sensing we publish a guide to help developers and asset owners cut through the hyperbole of what technologies will help them with cable help.
