Marine & Coastal

Maritime Planning, Assessment and Marine Engineering Consulting services

Multidisciplinary Maritime Engineering Services across the Entire Project Lifecycle

Our marine engineering consulting services team, comprised of the industry’s most talented marine engineering practitioners, can help provide intelligent and innovative thinking to marine facilities, whatever their size or scale.

Ayesa specialises in comprehensive marine engineering services for the expansion and development of ports and harbours across a wide spectrum of infrastructure including general cargo ports, fishing ports, dry and liquid bulk cargo terminals, cruise terminals, marinas as well as Ro-Ro and ferry ports. We help clients meet challenges such as climate change, aging infrastructure, changing regulations, and embracing new market opportunities. Where necessary, our global port consultants supplement marine engineering designs, integrating them with the adjacent intermodal connections, logistics management, landside infrastructure, and our client’s sustainability and resilience goals. 

Navigating growth in the maritime industry poses various challenges for port operators around a range of issues: 

  1. Navigating Regulatory Constraints: Addressing the intricate web of regulatory requirements to ensure seamless compliance and operational efficiency.

  2. Enhancing Berth and Channel Access Depth: Adapting to the demands of larger ships by optimizing berth and channel access depth for efficient and secure maritime operations.

  3. Streamlining Navigation for River Ports: Overcoming navigational constraints for river ports to facilitate smooth and safe passage for vessels. This also includes tackling dredging issues specific to river ports to maintain optimal water depths for vessels to navigate effectively.

  4. Managing Lateral Spread of Port Infrastructure: Strategising port infrastructure development to mitigate the lateral impact on neighboring seafronts and ensure sustainable expansion.

  5. Harmonizing with Adjoining Cities: Balancing the growth of port facilities with the dynamic needs and constraints of adjoining cities, fostering collaboration for mutual benefit.

  6. Alleviating Strain on Local Transportation Networks: Proactively addressing challenges related to the overburdening of local road and rail networks, ensuring efficient connectivity and minimizing disruptions.

  7. The energy transition: Ports are crucial hubs for the offshore wind industry, supporting the assembly, installation, and maintenance of wind turbines. They serve as logistical centers for the transportation of wind turbine components, providing storage facilities and infrastructure for assembly. Additionally, ports play a pivotal role in vessel operations, accommodating specialized ships for turbine installation and maintenance activities in offshore wind farms.Ports are evolving into O&M hubs for both offshore and onshore wind facilities. To align with the energy transition, ports are adapting their infrastructure to accommodate the unique needs of the renewable energy sector.

Our client-centric approach aims to understand and address these challenges comprehensively, aligning our strategies with the specific needs of port operators to foster growth, compliance, and sustainable development.

Our marine engineering teams provide innovative value-driven solutions for:

  • Master planning
  • Design of ports 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 marine engineering projects such as Haulbowline in Ireland or Broughty Ferry in Scotland showcases our expertise in protecting coastlines against climate change.  In addition, we have provided marine engineering solutions, including design and consultancy for 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. 

Complex marine 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 marine engineering services consultancy, we 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 marine engineering consultancy services offering, we aim to add value thinking beyond the brief to deliver lasting impacts to clients and projects.
