Marine & Coastal

Maritime Planning, Assessment and Engineering Design

Multidisciplinary Maritime Engineering Services across the Entire Project Lifecycle

Our marine engineering services team, led by the industry’s most talented practitioners, can help provide intelligent and innovative thinking to marine facilities, whatever their size or scale.  We design ports, coastal and marine structures that help clients meet challenges such as climate change, ageing infrastructure, changing regulations, and embracing new market opportunities.  Where necessary, our global port consultants supplement marine designs, integrating them with the adjacent intermodal connections, logistics management, landside infrastructure and our client’s sustainability and resilience goals.

Our teams provide innovative value-driven solutions for:

  • Master planning
  • Design of port and harbours
  • Design of waterside marinas, waterfronts, beaches, quays, parks and jetties
  • New developments and additions to terminals and facilities
  • Environmental assessments and monitoring
  • Feasibility studies
  • Coastal modelling and design
  • Planning and design of both soft and hard coastal protection structures
  • Dredging and reclamation projects
  • Flood and erosion protection schemes
  • Beach management programmes
  • Project management consulting, construction support and CQA Services

Our work on projects such as Haulbowline in Ireland or Broughty Ferry in Scotland showcases our expertise in protecting coastlines against climate change.  In addition, we have consulted and designed ports with diverse needs, including Dubai Port, Aqaba New Port, Dublin Port masterplan, Greenore and Lowestoft Port in the UK, delivering next-generation port infrastructure. 

These complex engineering projects require expertise in regulation and permitting, maritime and port operations, structural and geotechnical engineering, site investigations, marine ecology, dredging and reclamation, project management, contract administration and site supervision.  In addition, our clients can avail of our in-house expertise in various specialist areas, including modelling, flooding, ecology, marine biology, geotechnics, geomorphology, hydraulics, navigation, dredging & reclamation, and aquaculture.

As a multi-disciplinary consultancy, Ayesa UK, Ireland and Middle East can combine marine engineering with broader transport and infrastructure specialisms to deliver a holistic design and delivery service.  With clients at the core of our service offering, we aim to add value thinking beyond the brief to deliver lasting impacts to clients and projects.
