Our Net Zero Accelerator® digital platform houses a diverse range of powerful web and mobile applications across our expertise with one thing in common: they all deliver at least 50x improvement in cost, time and effort compared to conventional approaches that trap value and limit visibility; designed to add shareholder value, reduce risk and accelerate your net zero journeys.
Intended User of the Dynamic Cable Rating Application
Developers, funds, utilities, investors, buyers/sellers of offshore wind projects looking to save £10’s mn in capex by using our dynamically rated cable approach based on combining established IEC methodologies which can help reduce the size and number of cables. This digital tool is only available alongside our cable consulting services.
The Problem
Subsea cables have traditionally been designed assuming that the cables operate at full load with a conductor temperature at the maximum permissible level for the lifespan of the cable system. Steady state thermal rating therefore delivers a conservative thermal rating that fails to optimise the cable asset over its service life often limiting the potential power transmission. In addition, the IEC algorithms do not take into consideration the time taken to heat the thermal mass of the installed environment assuming instead a worst-case scenario of steady state temperature. There is an industry need to bridge the gap between conservative steady state ratings and dynamic in-service thermal ratings, monitored in real time.
Our Solution
In response to the industry need, ITPEnergised developed a series of dynamic rating digital tools to address the need to model the thermal performance of cables in service more accurately and therefore offering the opportunity to lower cost. The methodology combines established IEC principles and leading academic research on modelling thermal performance of cable systems with intermittent generation. The combination of a familiar steady state baseline and an iterative algorithm to reflect constant output change from offshore wind turbines has been developed into an effective digital tool by ITPEnergised.
Typical benefits
