  • Inter-array cable layout optimisation
  • Export cable route development
  • Cable thermal rating (IEC 60287)
  • Cable protection and crossing design
  • Burial depth assessment and specification

Project Management

Offshore project management and programme delivery, from tender support through installation oversight and commissioning.

  • Installation programme scheduling
  • CAPEX modelling and cost control
  • Weather-adjusted vessel programming
  • Tender evaluation and support
  • Client-side project representation
  • Risk and change management

Consenting & Environmental

Technical inputs for development consent applications, environmental assessments, and regulatory submissions.

  • DCO cable parameter envelopes
  • PIER and Environmental Statement inputs
  • EMF assessment and modelling
  • Receptor and impact analysis
  • Decommissioning assessments
  • Regulatory support and liaison

Feasibility & Advisory

Early-stage technical assessment and due diligence for offshore cable projects, acquisitions, and investment decisions.

  • Desktop studies and feasibility reviews
  • Technical due diligence
  • Concept and option studies
  • Data gap analysis
  • Survey specification and review
  • Expert advisory and peer review
Technology Platform

Proprietary software built for cable engineering.

Electrothermal's engineering services are powered by CableTrack — our proprietary software platform that automates and accelerates critical cable engineering workflows. Where traditional approaches rely on manual spreadsheets and bespoke tools, CableTrack delivers consistent, auditable outputs in a fraction of the time.

CBRA 7-step risk pipeline — vessel traffic, burial feasibility, environmental
Layout 14-stream inter-array cable topology optimiser
Routing Cost-surface pathfinding with geometric enforcement
Programme Vessel scheduling with metocean weather persistence
CAPEX Itemised cost modelling with monthly cash flow
Reporting Automated professional reports with risk maps

CableTrack Platform

CableTrack is a modular engineering platform comprising six integrated phases — from project setup and data ingestion through risk assessment, layout optimisation, vessel programming, cost modelling, and cable routing.

The platform implements industry-standard methodologies (OWA CTC835, DNV RP-0360, IEC 60287) through configuration-drivel workflows that are fully auditable and repeatable across projects.

  • Automated CBRA pipeline — weeks to hours
  • 14-stream cable layout optimisation engine
  • Weather-adjusted programme and CAPEX
  • Cost-surface cable routing with avoid-vs-remove economics
  • Configuration-driven — adapts to any project without code changes

Marine Insurance

Data-driven risk quantification to support underwriting, claims assessment, and liability analysis for submarine cable assets.

  • Risk quantification and scoring
  • Claims evidence and analysis
  • Liability assessment support
  • Asset condition monitoring
How We Work

Structured delivery aligned to your project timeline.

Every engagement follows a proven methodology. Whether it's a feasibility study, CBRA, layout optimisation, costed programme, or full desktop assessment — the approach is consistent and the outputs are traceable.

1

Scope

Define the project area, assessment requirements, and available data. Agree deliverables, programme, and applicable standards.

2

Ingest

Load and validate project data — AIS records, survey data, seabed conditions, metocean data, cable schedules, and constraint information.

3

Analyse

Run automated analyses through CableTrack: risk assessment, layout optimisation, programme scheduling, and cost modelling.

4

Deliver

Apply engineering judgement, generate professional deliverables, and provide ongoing support through installation and operations.

About Electrothermal

Engineering consultancy, powered by technology.

Electrothermal is a UK-based offshore cable engineering consultancy founded on the principle that better tools produce better outcomes. We combine hands-on project delivery experience with proprietary software automation to provide services that are faster, more consistent, and fully traceable.

With direct experience in submarine cable routing, burial assessment, programme delivery, and offshore wind development, we understand both the technical detail and the commercial reality of complex cable projects. Our proprietary CableTrack platform ensures that every analysis is repeatable, every output is auditable, and every deliverable meets the standards that clients and regulators require.
