Cable Design and Selection
Voltage, material, cross-section. Three decisions. One optimisation.
Voltage level, conductor material, cross-section and system architecture are not downstream choices to be confirmed after routing. They are coupled design variables that shape the entire grid connection system. Rezo evaluates them together, so the design you arrive at is genuinely optimal, not just locally refined.
Cross-Section Selection
Bigger is not always better. But sometimes it is.
Larger cross-sections allow more turbines per string and reduce lifetime losses. But they also increase minimum bending radius, affecting termination works and potentially foundation design. Rezo quantifies the lifetime cost impact of each cross-section choice so the decision is grounded in project economics, not engineering convention.
Not sure where the optimal trade-off lands for your project? Rezo's sensitivity analysis lets you vary the maximum cross-section and immediately see the cost implications across the full design.

Supply Chain Simplification
Fewer cable types. Simpler supply. Easier installation.
Every additional cable type in a project adds complexity across multiple disciplines. In Rezo, you set a maximum number of distinct cross-sections and the optimisation reruns immediately, quantifying the cost of that constraint so you can make an informed trade-off. The benefits of simplification go beyond cost:
Reduced procurement risk with simplified production requirements
Simplified vessel load-out and installation planning
Lower overall project cost through reduced supply chain complexity
Conductor Material
Copper or aluminium? The answer is not always obvious.
Copper conductors carry more current per cross-section, which means fewer or smaller cables for the same power. But copper costs more. The right choice depends on your specific energy price assumptions, string lengths and lifetime loss calculations, and the answer shifts as those inputs change.
Rezo evaluates both materials on an equally optimised basis, so the choice is grounded in numbers rather than convention.

Voltage Level
132 kV is coming. Do you know what it means for your project?
Higher voltage means fewer strings, less cable and lower lifetime losses. But 132 kV availability is uncertain for many projects, and the business case depends entirely on your specific layout and export concept. Rezo re-optimises the full array at any voltage level in minutes, giving you a directly comparable result against your current baseline.
Not sure whether 132 kV will be available in time? Rezo's sensitivity analysis lets you quantify exactly what is at stake if the decision goes either way.

Start Fast, Go Deep
Built on templates.
Tailored to your project.
Rezo ships with a pre-built template library maintained by Enersynt's offshore engineering team, including a cable library covering the key inter-array and export cable types needed to get started on any project immediately:
Use pre-built templates for rapid scenario exploration
Adapt them to your project constraints and save your own
Build institutional knowledge that stays in the platform across projects

The full picture, not just cable design
Cable design and selection does not exist in isolation. Rezo connects every cable decision to the routing, substation location and lifetime cost optimisation that together determine the true cost of your grid connection.
Intelligent Route Finding
The optimal cable still needs the optimal route. Rezo optimises routing and cable design together, so the two are never in conflict.
Lifecycle Cost Optimisation
Finding the optimal route is just the beginning. Minimising the cable cost along that route is not the same as minimising the lifetime cost of operating it. Rezo accounts for both.
System-Wide Optimisation
Optimising the inter-array in isolation misses the bigger picture. Rezo balances routing, substation location and export cable together as a single system.
Find out what your grid connection design is really costing you
Run your project through Rezo and get a defensible, lifecycle-optimised grid design that accounts for every cost, upfront and over the lifetime of your asset.
