Integrated Nearshore, Landfall & Onshore Cabling Civil Engineering
Specialist nearshore, landfall and onshore cabling civil engineering design. HDD compound design, geotechnical, and temporary works for infrastructure corridors.
Nearshore & Landfall Engineering
Cable landfalls and nearshore environments present some of the highestārisk engineering challenges in transmission and renewables projects. Arthian provides integrated nearshore engineering, HDD landfall design, and marineātoāonshore interface support to ensure safe, efficient and compliant cable installation from seabed to substation.
Our teams combine civil, geotechnical, environmental and temporary works expertise to deārisk complex intertidal works and deliver buildable, costāeffective solutions.
Our Nearshore & Landfall Capabilities
- Nearshore geotechnical assessment and ground model development
- HDD feasibility, alignment design and exit/entry engineering
- Cable pullāin engineering and construction methodology
- Cofferdam, shoring and intertidal temporary works design
- Tidal window planning and access strategy
- Environmental constraints, permitting and regulator liaison
- Marine contractor interface management
- Landfall compound design and enabling works
Infrastructure Corridor Capabilities
Arthian delivers specialist engineering across the full cable corridor ā from nearshore and landfall environments to onshore civil engineering, geotechnical design and temporary works. Our multidisciplinary teams help developers, EPCs and contractors reduce risk, optimise constructability and deliver compliant, efficient cable infrastructure.
We support projects from early feasibility through detailed design and construction, providing the engineering assurance needed for safe, predictable delivery.
We Support:
- Renewable energy cable routes (solar, wind, battery storage)
- Utility infrastructure (electricity, telecoms, water)
- Road, rail, and multi-modal corridors
- Strategic land and energy transition projects
Onshore Cabling Civil Engineering Design
Arthian provides complete civil engineering design for onshore cable routes, supporting renewable energy, transmission and distribution projects across the UK and Ireland.
Our engineers deliver practical, buildable solutions that optimise safety, cost and programme performance.

Frequently Asked Questions
Do I need civil engineering design for cable planning?
Yes-especially for planning applications, route feasibility, and construction readiness.
Can you help with trench and duct design?
Absolutely. We provide detailed trench profiles, ducting layouts, and interface engineering.
Do you support infrastructure and multi-site projects?
Yes-we work across single-site and distributed portfolios, including strategic infrastructure corridors.
What about permitting and consents?
We support applications for highways, environmental, and land drainage consents across the UK.
