Marlinks

For offshore wind professionals, the risk of submerged power cables is crystal-clear: While failure of the cables will take millions in repair costs and lost revenues, current cable monitoring is nevertheless only periodic or always one step behind.

Marlinks continuously monitors your offshore power cables: our advanced software application focusses on the burial depth of the cables, using thermal models combined with their internal distributed temperature measurements (DTS). This way, Marlinks reduces your total cable risk during the operations phase and protects you from damages due to unburied cables. Moreover, our trend-analysis allows an early warning, and literally buys you time to properly plan responsive actions. As government grants drop and margins get smaller, Marlinks can help you to avoid unexpected costs and secure your power links.

CABLE MONITORING

dob_software_white-2

DOB SOFTWARE

Our Depth of Burial software (DOB) continuously calculates the burial depth of your export and inter-array cables, monitoring ampacity, distributed temperature and types of soil. This results in an overview of overall burial depth, adjustable alarms and trend analysis, all of which can be integrated in your scada system or made accessible through stand-alone software.

continuous_risk_assessment_white-2

CONTINUOUS RISK ASSESSMENT

The Carbon Trust CBRA Methodology (CTC835) determines the methodology for cable risk assessment. Three parameters are usually taken into account: fishing activities, ship anchoring and burial depth. These conditions are often considered to be constant, but particularly burial depth can change significantly because of factors like seabed mobility.

thermal_modelling_white-2

THERMAL MODELLING

Based on the data we get from the Marlinks burial depth model, we achieve an extensive understanding of the thermal conduct of the soil encapsulating a cable. With this knowledge, we predict the heat trajectory from cable to seawater, including conductive or convective behavior. Our models are based on different soil parameters, such as grain size differences, porosity and burial depth.

seabed_mobility_studies_white-2

SEABED MOBILITY STUDIES

Based on experience from our previous projects, as well as cable readings with our burial depth software and/or our survey results, we can monitor sediment behavior and seabed mobility for your assets. The variables we use for our modelling are numerical or analytical, and take into account soil properties and hydrodynamic changes. The outcome is then used to predict morphological processes.

OUR ROADMAP

ANALYSIS & ADVICE
roadmap_analysis_advice

Analysis & Advice

Together we check the different data sources such as cable and soil intel on their quality and significance. In doing so, we assess whether extra measurements are needed.

In addition, Marlinks checks the characteristics of the DTS and assesses the accuracy obtained. Furthermore, we investigate how the automatic data transfer of load and DTS data can be organised: we assess the IT requirements for an automated interface with your scada system, so it can show all necessary alerts.

Our joint analysis results in a detailed estimate, including a plan of action on how Marlinks implements its solution into your systems.

IMPLEMENTATION & ROLLOUT
2_implementation_rollout

Implementation & Rollout

If necessary, we start the process with extra measurements on your assets. Once this intel is completed, our models are calibrated to obtain a custom-made model, designed on your cable and soil characteristics. Moreover, the automatic data transfer is configured both from your systems to ours and from our application to your scada. Eventually, Marlinks compares the output with survey data as a quality check to guarantee a 100% waterproof outcome.

OPERATIONAL
3_operational

Operational

The system is now up and running and calculates the burial depth of the cable, based on the load- and DTS-data. The information obtained is automatically transferred to your scada system (e.g. Alarm) and/or can be viewed on Marlinks͛ dashboard. In addition, we generate periodic reports, including an overview on the burial depth, a trend analysis and an updated cable risk assessment.

SUPPORT

Support

During the operation phase, unexpected things can always occur. Therefore, we have an extended support service, covering software bugs or interface problems between our systems and yours. This dedicated Marlinks team also helps you in explaining unusual results or in the correct interpretation of the data, including the risks involved.

CASE STUDY

Parkwind

From the beginning, leading offshore wind operator Parkwind had a risk-based approach on their cable assets. Bathymetric surveys showed the present seabed mobility was significant, yet very hard to predict. Even with more frequent surveys, recurrent vulnerable exposure of cables resulted in ad-hoc reburial campaigns. Those are costly and sometimes not effective, as post-analysis subsequently showed.

Parkwind developed a tool for continuous cable risk assessment themselves, but the burial depth status still remained an unknown factor.
