What our customers say
“Using C-Kore delivered value to Shell in several ways. Firstly, there was a tangible vessel time saving of approximately 2 days. We requested an engineer for the first deployment, but later were happy operating the equipment ourselves, so there was a personnel saving as well. Secondly, C-Kore gave us an improved diagnostic capability, allowing us to discover additional faults in the field, that would have been masked by the primary fault if traditional diagnostic methods were used. We were also able to gather timestamped diagnostic reports for all the branches and many individual components of the subsea infrastructure, allowing us to identify marginal components for the future IR surveillance and/or proactive maintenance.”

C-Kore vs. Traditional Methods
C-Kore tools overcome the issues of traditional testing. They remove the problems that plague downline based testing, from the slow deployment and dubious reliability of the downlines themselves to the effects of inclement weather on deck-based reading accuracy. Likewise, as C-Kore units are deployed directly by the intervention vessel there is no longer a need to use slow and cumbersome platform-led testing, where intervention vessels are left waiting for a busy platform to find time for their tests. Both approaches can easily add many hours to every test, adding up to days of vessel time.
By removing the need to use downlines or platform-led testing, C-Kore tools significantly speed up fault-finding operations and reduces downtime required for fault investigation. When deployed by ROV, C-Kore units easily fit in the tooling tray for extremely fast deployment. For divers, C-Kore is lightweight and easy to handle. We use an innovative low-voltage testing technique, so divers do not have to retreat during testing and SCMs are safe from damage. Testing itself is also faster than with traditional methods thanks to test automation and data logging.
Deploy with diver or ROV
Can be configured in advance and used by general personnel
Deploy in ROV tooling tray, diver cage or basket
Hand carry for mobilisation, no deck space required
Not affected by adverse weather or environmental factors
Specialist operator required to run test equipment on back-deck
Extra time required for deployment and recovery, including vessel step-off
Haulage, deck-space and sea fastening required for mobilisation
Humidity and weather affect readings, downlines susceptible to damage
Testing by the intervention vessel, results within minutes
Field or channel only has to be isolated once
Safe for divers, no retreating, no on-deck testing and permits
All data displayed and logged, automatic reports generated
Reliant on platform time for testing, potentially hours of delays per test
Repeated permits/paperwork delays for field isolation and reconnection
Divers must clear work site while field is tested from platform
Reliant on second-hand data reported from test personnel on platform
The C-Kore Rental Service
The first step is to talk to us. We have helped many customers configure C-Kore units for their applications and have a wealth of experience to draw on.
Commonly, after discussing the field layout and fault-finding strategy we pre-configure the C-Kore units before they leave the factory so all the end user has to do is remove them from the box and deploy. Configuration can still be changed later in the field if needed.
We can help you decide:
When should a test routine start
This could be a light or proximity sensor activation from ROV lamp or diver contact
Which lines should be tested
Multiple combinations of inputs and seawater can be tested with any kind of measurement (IR, CR, TDR, etc)
What should be displayed
All results or just a summary can be shown on the built-in display after each test
Every unit is electrically and hyperbaric tested before dispatch and pre-loaded with configuration data if required.
The C-Kore units arrive in small pelican cases, which can be easily hand carried onto the vessel and take very little storage space.
Once the fault-finding scope of work is reached it is simple to deploy and use C-Kore tools:
Fit activation plug
Fit the activation plug to take the units out of transport mode and enable sensors
Deploy units subsea
Place units in ROV tooling tray (scoop), diver basket or work basket to get to the worksite fast
Connect and test
Plug a C-Kore unit into the subsea infrastructure and use the light or proximity sensor to start measurement
Instant feedback on built-in OLED display to see measurement results subsea
Every result is datalogged and the units do not need to be recovered between tests. Continue testing subsea until all faults have been found and there is a convenient point to recover the units.
When the fault has been found and subsea measurement is complete it is easy to recover and return the units:
Recover to deck
Bring the units back the same way they were deployed, with the ROV or in a basket/cage
Connect via USB and use a built-in wizard to download full test reports
Once all scopes involving C-Kore are complete it’s simple to demob the units. Just place them back in their cases and dispatch via a normal parcel courier, no cranes or haulage required.
