CoreTEST Substation

CoreTEST Substation proactively monitors off- shore array and export cables up to 150km in length. Cable damage is identified in real time. A fully graphical display continuously shows the quality of the cable at all times. Audio, email or SMS alarms are triggered if cable limits are exceeded to immediately warn of problems with the cable integrity.

Mapping

The route of the cable and the exact location of any fault is displayed on a fully zoomable map. All alarms include the precise GPS location of the fault to reduce time finding and repair time.

SCADA Integration

In addition to sending notification by email or SMS text message the alarm status can be integrated to the substation control system using a number of industry standard protocols. • Modbus • OPC / OPC XML / OPC UA • DNP3 • IEC 60870

Monitoring Repairs

CoreTEST can be temporarily deployed to monitor power cables during repair or maintenance work. Any damage or stress on the cable is immediately alarmed.

Proactive Asset Monitoring

Testing at frequencies that are particularly sensitive to bending allows subtle sea bed condition changes to be identified. Issues such as scouring causing exposure of the cable can be identified when analysing the historical data.

All 288 Cores Tested

CoreTEST Substation tests power cables with up to 288 fibre cores although larger units are available on request. All cores in a cable are tested in turn or specific individual cores can be selected for intensive testing.

Saving time and money

Thanks to the continuous test method and fully integrated GPS mapping any cable problems are identified sooner than with traditional methods. Precision mapping allows maintenance teams to be guided to the exact location of the fault. For more information or to arrange a demonstration or visit to a site please email info@optalay.com.

CoreTEST Marine

CoreTest Marine proactively monitors off-shore array and export cables as they are being installed or repaired. Quality problems are identified in real time. A fully graphical display on the bridge continuously shows the quality of the cable as it is being installed. Audio alarms are triggered if cable handling limits are exceeded to immediately warn of problems with the cable integrity.

Traditional cable testing

Once a power cable is installed on the sea bed it is cut to length and then optically tested for insurance purposes. This manual test can take place only after the cable has been cut. Engineers are based on the vessel 24x7 to test each section of cable as it is cut from the drum. Following testing the cable is directly installed or wet-stored for later installation.

Continuous testing

CoreTEST Marine is different. It is fixed to the centre of the cable carousel allowing it to continuously monitor the cable as it is being installed. Any issues are visible immediately without having to wait until the cable is cut. A final test is performed prior to the cable being cut to length. These tests verify the cable has not been damaged during handling, shipping or installation.

All 288 cores tested

CoreTEST Marine tests cables with up to 288 fibre cores although larger units are available on request. All cores in a cable are tested in turn or specific individual cores can be selected for intensive testing.

SCPI Connect

CoreTEST Marine can connect to external monitoring equipment using the SCPI control protocol. This allows additional tests (for example electrical resistance) to be performed and included with the fibre test result.

Saving time and money

Thanks to the continuous test method cable problems are identified sooner than with traditional cut and test methods. By automating the testing process offshore manpower is reduced along with the accommodation and logistic costs associated with offshore work.

CoreTEST Substation

Continuous Monitoring The CoreTEST equipment is located at the substation on either end of the cable to continuously monitor and immediately alarm if cable damage occurs. Historic Analysis Analysis of the data over the long term allows subtle cable movements to be identified. Alarm Notification If user defined limits are exceeded alarms are sent via audio, email or SMS text message. The GPS location of the fault is included in each message to accurately pinpoint the location of the problem. AIS Marine Traffic Integration with the AIS Marine Traffic database allows the location of all vessels in the wind farm area to be recorded along with each test result. Should trawl or anchor damage occur all vessels in the area at the time are known. SCADA Integration Alarm conditions can be sent via a number of industry standard protocols (Modbus, OPC, DNP3 or IEC 60870)

CoreTEST Marine

Continuous Monitoring Monitoring from the centre of the cable carousel allows CoreTEST Marine to continuously test a cable as it is being installed. Problems can be identified before the cable is cut saving time and money. Total Traceability The GPS location of the cable laying vessel is recorded with each test result allowing the location of any problems to be accurately identified. The GPS route of the cable is automatically created as the cable is installed. Fewer engineers on vessel By automating the cable testing process the number of engineers based on the cable laying ship can be reduced. Full remote control of the test equipment is possible where internet access is available. AIS Marine Traffic Integration with the AIS Marine Traffic database allows the location of all vessels in the area to be recorded as the cable is installed.
