Ports & Harbours Consultants
Keeping ports operational today. Engineering a lower-carbon tomorrow.
Arthian provides multidisciplinary engineering and environmental consultancy for ports, harbours, marine terminals and waterfront infrastructure. From jetty and quay inspections, structural assessments and asset life extension to energy strategy, electrification and decarbonisation, we help port operators understand existing assets, prioritise investment and prepare critical infrastructure for the future.
Port Infrastructure Engineering, Inspection & Life Extension
Ports and harbours depend on ageing marine and landside infrastructure that must remain safe, operational and resilient despite demanding environmental conditions, changing vessel and cargo requirements and increasing pressure on capital investment.
Arthian supports port owners, harbour authorities, terminal operators and industrial waterfront facilities throughout the asset lifecycle. Our civil, structural and geotechnical engineers undertake marine inspections, condition surveys, structural and geotechnical assessments, remediation design, strengthening, temporary works and asset management to establish asset condition and capacity and identify proportionate interventions.
Rather than defaulting to replacement, we help clients understand where existing infrastructure can be maintained, repaired, strengthened or adapted, extending operational life while targeting investment where it delivers greatest value.
Supporting Belfast Harbour's Decarbonisation Strategy
Arthian supported Belfast Harbour in understanding its current and future energy requirements and developing a practical pathway towards decarbonisation. Our work considered existing energy infrastructure, future demand and renewable and low-carbon technology opportunities to develop a phased investment roadmap aligned with operational and commercial priorities.
“Arthian brought real clarity to a genuinely complex energy picture across our estate. Their feasibility work and phased roadmap gave us a practical, evidence-based way to prioritise renewable investment, without losing sight of commercial and operational realities. It’s given us a clear framework to keep moving on our decarbonisation goals with confidence.”

Our Ports & Harbours Expertise
Our approach begins with understanding the condition and performance of existing infrastructure.
Through marine inspections, condition surveys, structural assessments, asset management planning and maintenance strategies, we provide the evidence needed to identify risks, prioritise repairs and optimise future investment. These inspection-led services naturally evolve into remediation design, structural repairs, coastal and marine engineering support, flood risk advice and resilience planning, ensuring clients have a clear pathway from assessment through to intervention. By combining technical excellence with practical asset management expertise, we help operators maximise the lifespan of quays, jetties, berths, seawalls, slipways and associated marine infrastructure. We can assist with:
Understanding the condition of marine assets is fundamental to effective management and long-term investment planning. Our team undertakes detailed marine inspections and condition surveys to assess the structural integrity, operational performance and remaining lifespan of quays, jetties, berths, seawalls and associated infrastructure. By combining on-site investigations with technical analysis, we develop robust structural assessments, asset management plans and maintenance strategies that help clients prioritise interventions, manage risk and make informed capital investment decisions. This evidence-led approach provides a clear foundation for future maintenance, refurbishment and resilience planning.
Where inspections identify deterioration, defects or capacity constraints, we provide comprehensive structural condition assessments to determine the most appropriate course of action. Our engineers evaluate asset performance, identify causes of degradation and develop practical remediation designs and repair specifications tailored to operational requirements and budget constraints. We can support clients throughout procurement and delivery, providing technical advice during tender processes and construction oversight to ensure remedial works achieve their intended outcomes. This creates a seamless transition from identifying issues to implementing effective engineering solutions.
Effective asset management extends beyond addressing immediate maintenance needs and focuses on the long-term performance and resilience of critical infrastructure. We work with asset owners to develop lifecycle strategies that balance operational demands, future investment requirements and emerging environmental challenges. Our services include resilience assessments, climate adaptation planning, flood risk analysis and long-term capital planning, helping clients understand how assets may perform under future pressures. By taking a strategic approach to asset management, we help organisations maximise value, improve reliability and enhance infrastructure resilience over time.
Marine structures play a critical role in supporting commercial operations, transportation networks and coastal activity. Our quay, jetty and seawall assessments evaluate asset condition, structural capacity and operational suitability, identifying opportunities to improve safety, extend asset life and support evolving business requirements. Drawing on our marine civil engineering expertise, we can progress assessment findings into detailed design solutions, refurbishment schemes, infrastructure upgrades and capacity improvement projects. This integrated approach enables clients to move confidently from understanding asset performance to delivering targeted enhancements that support future growth.
Delivering maintenance and repair projects often requires consideration of a much wider regulatory and environmental context. Alongside engineering support, we provide access to specialist environmental permitting, ecology, planning and sustainability expertise to help projects progress efficiently and compliantly. Whether undertaking routine maintenance, emergency repairs or major refurbishment works, we help clients navigate consenting requirements, minimise environmental impacts and identify opportunities to improve sustainability outcomes. By bringing together multidisciplinary expertise, we provide a coordinated route from repair planning through to successful project delivery.
