Marine cable routing platform

Unreal Routing. Route the whole boat. Prove it complies.

Cable routing is still the spreadsheet discipline in shipbuilding — and its mistakes surface at install. Unreal Routing puts the tray network, every circuit, the marine electrical rules, and the shop floor in one database, and meets your designers in the CAD tools they already use.

The problem

Thousands of circuits. Hard rules. Errors found at install.

Every circuit on a vessel is bound by segregation, tray fill, weight, voltage drop, ambient derating, and flag-state or class rules that differ by vessel. Most yards still manage that in spreadsheets and marked-up drawings, so the engineering office, the CAD model and the shop floor each keep their own list. The mismatches show up as rework: re-pulled cable, overfilled trays, and findings after the inspector's walk-through.

How it works

From tray model to pulled cable, in one database.

Load the vessel

Import your cable schedule, devices, compartments, and tray network from CSV or Excel — or push the tray model straight from AutoCAD, Navisworks, or Revit.

Route the whole boat

Route the circuit you just changed in seconds, or every circuit on the vessel in one server-side run — segregation, tray fill, weight, and compartment restrictions enforced inside the pathfinder.

Prove it complies

Set the regime the vessel is inspected under. The rule engine runs the checks that regime requires and cites the section behind every finding.

Run the shop floor

Pull sheets, drum assignments, labels, and MTOs come from the same database — and installers update status by scanning a QR code.

Every circuit, checked as it routes

Batch-route the schedule, then read each circuit’s health — voltage drop, installed ampacity, and breaker sizing — right on the list. Import the schedule from CSV or Excel to start.

Compliance, with the citation

Set the regime once — here USCG 46 CFR Subchapter J — and every check reports what it tested, how many it flags, and the rule behind it. On the demo vessel 23 of 26 pass — hanger loads and every bend included — and the three open issues are planted; a note says what the bend checks rest on, and a note is never counted as an issue.

Unreal Routing Compliance page: regime USCG 46 CFR Subchapter J, non-compliant, 23 of 26 checks passing (1 with notes), 3 open issues — voltage drop, commissioning and overcurrent device sizing — then the bend radius basis passing with a note, each with its count and what it checked

Errors caught at the desk, not at install

Each circuit carries its own findings in plain language — here a floodlight branch over the voltage-drop limit, with a suggested conductor size and the cumulative drop back to the generator. Fault withstand, breaker sizing and watertight transits are checked the same way.

One view of the whole vessel

Open compliance findings, routed and approved percentages, the fullest trays, installation progress and the shop-floor counts — computed in the database, not the browser, for vessels sized to 100k circuits.

Unreal Routing dashboard for the demo supply vessel: 223 circuits 100% routed and 115 approved, 3 compliance findings (2 errors, 1 warning), tray fill hotspots, 207 nodes and 211 segments, installation progress bars, and cut, terminated and tested counts

The shop floor on the same data

Cut and pulled lengths, termination and test results, install status, and drum assignment for every circuit — recorded where the work happens.

Feature breakdown

Design, compliance, and the shop floor — connected.

Cable-list tools stop at the list. Generic raceway tools don't know the marine rules. Unreal Routing connects the routing, the rules and the shop floor.

Routing engine

Constraint-aware routing

Shortest compliant path per cable, honoring segregation classes, tray fill and weight limits, pass-through-blocked compartments, and per-compartment cable-type bans. Route one circuit, or the handful a change touches, in seconds — about 1 s, under 5 s on a cold connection, on a 100,000-circuit ship in production — or the whole vessel in passes when you need it.

True cable placement

A cross-section solver packs every cable into its real slot on the tray — banking, bank gaps, class separation — so the 3D view and the CAD drawings show where cable actually sits, not a centerline.

Change-safe re-routing

Move a node or edit a run and every routed length through it updates; change a circuit’s endpoint and a route that no longer reaches it is cleared and flagged, never left on a silently invalid path. Re-route the lot in one batch; overfilling a tray is an explicit, confirmed override.

Marine compliance & electrical

Regime-aware rule engine

Up to 26 checks under USCG 46 CFR Subchapter J, fewer under ABS River & ICW Rules, IEEE 45 or IEC 60092 — including conductor sizing (46 CFR 111.60-4), emergency-cable routing (112.05-5(f)), overcurrent protection (111.50-3(c)), and every route’s bends and continuity — plus redundant feeders checked for separate trays and transits.

Ampacity as installed

Chart ampacity corrected for how the cable is actually run: double-banked or bunched on its real route, the hottest compartment it passes through, and its insulation class. One number, the same everywhere.

Full electrical calc suite

Voltage drop, derating, bend radius, short-circuit withstand, pull tension, conduit fill, breaker and battery sizing — plus electrical load analysis and cumulative voltage drop up the feeder chain.

Hardware, penetrations & equipment

Hanger assemblies, auto-generated

Downcomers, cross tiers, and banding or tapped hangers sized from the real cable bundle and the overhead steel, using FMD / RT&D part families or your own catalog. The BOM is orderable, not notional.

Penetration engineering

Roxtec-style multi-cable frames, MIL-S-24235 swage tubes, nylon tubes, and custom openings — with an automatic packing solver and fire-boundary checks on every transit.

Equipment prep

Engineer the last inch: entry hardware for every cable landing on every device, tube sizes suggested from cable OD, per-device prep sheets, and the hardware rolled into the MTO.

Manufacturing & installation

Drum management

Reel inventory with automatic first-fit assignment of cut lengths to drums, so the cable you order is the cable you pull.

Pull plans & batch pull sheets

Shop-floor pull sequences by drum, largest cable first, issued as frozen batch pull sheets with QR codes.

Floor mode

Installers scan a cable’s QR code at the job and tap big buttons — cut, pulled, terminated, tested. Status lands in the same database the office works from.

Program control

Multi-hull effectivity

One project is the contract baseline; each cable applies to all hulls or specific sister hulls, with per-hull circuit lists and per-hull compliance.

Change control

Approval locks a circuit at a revision, on the web and in every CAD plugin. When the model moves under it, the database flags it, logs what changed and why, and warns if the cable is already cut or pulled. Holds stop the floor.

Weight & CG from real routes

Cable weight spread along actual routed paths, rolled up by deck and compartment with center of gravity — and the basis disclosed, catalog vs estimated vs unknown.

Who it's for

Teams that route cable for a living.

U.S. commercial shipyards

Towboats, barges, OSVs, ferries, and workboats — USCG-inspected under 46 CFR Subchapter J and often ABS River & ICW classed. Both regimes are first-class in the rule engine.

Defense shipbuilders & electrical subs

Navy and Coast Guard programs: MIL-STD banking conventions, defense-supplier hanger hardware, MIL-S-24235 penetrations — and an on-prem option for programs that can’t use a public cloud.

Marine electrical design firms

Cable schedules, load analyses, weight reports, and drawing packages as deliverables — multi-project, multi-client, from one tool.

Refit & repair yards

Rebuild the cable picture over an existing review model in Navisworks, route the changes, and hand the floor current pull sheets.

Pilot program
