Ports & Maritime Specialty Contractor

U.S. Aqua provides on-call amphibious excavation, placement area maintenance, containment dike construction and repair, sediment removal, and shoreline stabilization for port authorities. On-call arrangements allow port operations teams to mobilize specialty crews and equipment quickly for routine maintenance, capacity restoration, and emergency response without re-procuring each scope of work.

Port maintenance dredging generates large volumes of dredged material that must be placed in confined disposal facilities (CDFs), also known as dredge placement areas. Over time these areas fill up and lose capacity, which restricts the port's ability to maintain navigation depth. Dredge placement area maintenance - including dewatering, capacity restoration, dike raising, and beneficial use removal of accumulated material - keeps these facilities operational and protects long-term dredging and navigation programs.

Yes. Active port and terminal facilities cannot be shut down for maintenance work. U.S. Aqua coordinates with port operations teams, terminal operators, and vessel traffic to schedule work in windows that do not interfere with cargo movement, vessel berthing, or terminal access. Crews are oriented to port-specific safety, security (TWIC), and access requirements before mobilization.

U.S. Aqua deploys amphibious marsh excavators, long-reach excavators, hydraulic and submersible dredge pumps, work barges, material barges, and support craft for port and maritime projects. Equipment is mobilized by barge, lowboy, or self-propelled to port project sites. The fleet is owned and operated by U.S. Aqua, which means it is available when the port needs it - not subject to subcontractor scheduling.

Yes. U.S. Aqua maintains rapid mobilization capability for emergency port and maritime work including post-storm channel and slip reopening, breach repair on placement area dikes, sediment removal after major weather events, and shoreline stabilization following damage. Owned equipment, full-time crews, and existing on-call relationships with port authorities allow us to respond when ports need specialty contractors on short notice.
