Intelligent Route Finding
Every obstacle has a price.
Rezo knows what it is.
Offshore cable routing is not just about avoiding obstacles. It is about understanding what each one costs and finding the route that minimises the total. Rezo models every spatial constraint simultaneously, so the design you get is the one that actually works in the field.
The Reality of Offshore Cable Routing
The shortest route on paper is rarely the cheapest one.
Real concessions are rarely clean. Exclusion zones, high-cost installation areas and existing infrastructure overlap, interact and compete across the same concession.
Every constraint has a price
The optimal path through one obstacle is rarely the optimal path through all of them.
Manual routing compromises
By the time you have resolved one constraint, you may have already compromised the next.


Exclusion Zones
Some areas simply cannot be crossed.
Rezo handles the full range of hard exclusions, automatically routing cables around them while finding the lowest-cost compliant path through whatever remains. Supported exclusion types include:
UXOs and shipwrecks
Nature protection zones such as gravel beds and coral reefs
Individual large boulders modelled as point exclusions with a defined avoidance radius
Any custom exclusion layer imported in standard GIS formats
High-Cost Installation Zones
Not every difficult area is off-limits. But it all has a cost.
Moving sand dunes, boulder clusters or stiff clay areas are not hard exclusions, but they carry elevated installation and long-term maintenance costs. Rezo weighs those costs against the alternative of routing around them, crossing when it is economically justified and avoiding when it is not. The result is a routing decision grounded in both technical compliance and economic reality, not engineering intuition alone.


Existing Infrastructure
Every crossing is a trade-off. Rezo makes the right one.
Subsea pipelines, power cables, telecommunication lines and other existing infrastructure introduce discrete crossing costs with engineering, contractual and commercial implications that go beyond geometry. Rezo models each crossing explicitly, optimising the number and location across the full inter-array network.
Crossing costs are often uncertain at early project stages. Rezo's sensitivity analysis lets you directly compare a minimum-crossings design against the lowest overall lifetime cost solution.

Cable Corridors and Concession Boundaries
Constraints define the space. Rezo finds the optimum within it.
Export cable corridors, concession boundaries, and restricted military or environmental zones define where cables can and cannot go. Rezo enforces these as hard boundaries while continuing to optimise for cost within them.
Whatever the shape of your design space, the result is always the best possible solution within it.

Built for the Full Project Lifecycle
New data should answer questions, not raise them.
Seabed knowledge evolves throughout a project. Your design should too.
Stay up-to-date
As a project matures, the picture of the seabed changes. New surveys and assessments should sharpen your design, not trigger weeks of rework.
Decisions backed by data
In Rezo, add a new constraint layer, rerun the optimisation, and turn new survey data into a concrete design decision, not a question mark.
Go Further
The full picture, not just intelligent routing
Intelligently routing is only the beginning. Rezo evaluates the full grid connection system and its long-term uncertainties to identify the topology that minimises total lifecycle cost.
Cable Design and Selection
The optimal route means nothing with the wrong cable. Rezo evaluates voltage levels, cross-sections, materials and string configurations together with routing, in a single optimisation.
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.
