Electrothermal is a specialist consultancy delivering offshore cable engineering and electrical trace heating design & installation, from feasibility through installation and operations. We combine deep engineering knowledge with proprietary software tools to provide faster, more consistent, and fully auditable project outcomes.
Electrothermal provides specialist engineering services across the full cable project lifecycle — from early feasibility and consenting through to installation support and operations.
Technical delivery across the full scope of submarine cable engineering — burial risk, routing, layout, thermal rating, and protection design.
Offshore project management and programme delivery, from tender support through installation oversight and commissioning.
Technical inputs for development consent applications, environmental assessments, and regulatory submissions.
Early-stage technical assessment and due diligence for offshore cable projects, acquisitions, and investment decisions.
Electrothermal designs and installs electrical trace heating systems for process, industrial, and subsea applications — from heat-loss calculation and cable selection through to installation supervision, testing, and commissioning.
We provide end-to-end trace heating engineering — from concept design and cable sizing through to site installation supervision and commissioning — for process industry, commercial, and subsea applications.
Our subsea cable engineering background extends naturally into direct electrical heating (DEH) systems for flowline flow assurance, where trace heating principles are applied at scale to prevent wax and hydrate formation in offshore pipelines.
Freeze protection and temperature maintenance for process piping, instrumentation, and equipment across industrial and commercial facilities.
Temperature maintenance for storage tanks, vessels, and bulk material handling systems where viscosity control or freeze protection is critical.
Direct electrical heating design input for subsea flowlines and pipelines, helping prevent wax and hydrate formation across offshore production systems.
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.
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-driven workflows that are fully auditable and repeatable across projects.
End-to-end cable engineering for fixed and floating offshore wind — from feasibility and consenting through installation and operations.
Route development and risk assessment for submarine telecommunications cables, including transoceanic systems and shore-end approaches.
Route assessment, risk analysis, and installation planning for HVDC and HVAC interconnector cables across all project phases.
Data-driven risk quantification to support underwriting, claims assessment, and liability analysis for submarine cable assets.
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.
Define the project area, assessment requirements, and available data. Agree deliverables, programme, and applicable standards.
Load and validate project data — AIS records, survey data, seabed conditions, metocean data, cable schedules, and constraint information.
Run automated analyses through CableTrack: risk assessment, layout optimisation, programme scheduling, and cost modelling.
Apply engineering judgement, generate professional deliverables, and provide ongoing support through installation and operations.
Electrothermal is a UK-based offshore cable engineering and trace heating 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.
Whether you need a CBRA, layout optimisation, installation programme, consenting inputs, route development, trace heating design & installation, or project management support — we can scope a solution around your timeline and data.
