Coastal Port and Marine

The Coastal, Ports & Marine Practice at APTIM provides services in four main business segments: Coastal Engineering & Restoration, Port Engineering and Equipment, Flood Control Engineering and Coastal & Marine Sciences.

We work with the public sector (federal, state and local governments) and private clients in the oil and gas, energy, telecommunications, agriculture, mining, port terminal operators, and any other market segment that needs to restore coastal environments or build and maintain infrastructure in rivers, bays, estuaries, coasts and the open ocean. We work collaboratively with our clients approaching complex projects with creative solutions and state-of-the-art science and engineering.
