Maintaining and developing port infrastructure and managing our marine and coastal environment are essential in today’s world. The ports and maritime sector is increasingly global, mobile and growing by the year. More than 70% of the world’s population live along coastal plains and ships carry 80% of global trade. With international trade forecasted to grow steadily and predicted to double by 2030, port infrastructure is characterized by a range, longevity and complexity of assets found in few other sectors.

Ports and maritime engineering require a particular expertise consisting of sound technical knowledge, coupled with practical experience in the operation and maintenance of facilities, infrastructure and systems that interface with a marine environment. We have global experience spanning all aspects of port planning and design, marine structural, and coastal engineering as well as procurement, construction, and project and program management. Our work is helping to connect communities and markets through safe and efficient access to water ways and the open ocean.

Our diversified maritime and civil engineering experience allows us to design facilities that satisfy a client’s particular requirements while maintaining flexibility for responses to future change. Combining knowledge, talent and ingenuity, we provide experience-based solutions whether looking at the feasibility of a new facility, repairing or expanding an existing asset or providing engineering services for a green field project. Services provided include all stages of a project from scoping and concept studies, pre-feasibility and feasibility studies through to execution. We have the expertise to address every stage of a maritime infrastructure project of any size.

We don’t just design the material handling and terminal systems, but all the facility components that go in and around it, including mechanical, structural, civil, electrical, controls and automation, and road and rail. Our port engineers also specialize in the design and construction of maritime structures including: berthing and mooring dolphins, bulkhead walls, quays, jetties, wharfs, piers and maintenance platforms.

The scope of work often includes: shore protection, dredging, breakwater, land reclamation, site access, bridges, piers, berths for vessels of all sizes and supporting marine infrastructure. Our maritime, mechanical & electrical, and infrastructure engineers work closely together to provide complete solutions to our clients.

Our coastal science and engineering specialists create sustainable shoreline designs and assess the environmental impacts of new coastal developments around the world by taking an integrated approach to the planning, assessment and management of coastal and marine environments to ensure their sustainable use and protection. We provide experienced advice on the adaptive design of coastal defence structures and landforms to prepare for a changing climate.
