Hydro Cat 1: A Purpose-Built Hydrographic Survey Vessel for the Gulf Coast's In-Between Waters

Every infrastructure project on the water starts with the same question: what's actually down there? For engineers, planners, and asset owners across the Gulf Coast, hydrographic survey is how that question gets answered, but it’s often the survey vessel itself that determines how effectively and efficiently that answer will come. That’s why we built the Hydro Cat 1.
Closing the Gap Between Small Survey Boats and Offshore Ships
A lot of hydrographic survey work falls into an awkward middle ground. A 20-foot boat can get into shallow water, but it can't carry the range of sensors, endurance, or crew capacity that a serious survey demands. A 100-foot offshore vessel has all of that capability, but it's overbuilt (and often slow to mobilize) for the nearshore, inland, and transitional waters where much of the work actually happens.
Hydro Cat 1 was designed to close that gap. It's a purpose-built hydrographic survey vessel that is shallow enough to reach the water our clients need surveyed, and capable enough to carry the full sensor suite that used to require a much bigger platform.
Hydrographic Survey Equipment and Client Benefits
Hydro Cat 1 carries a complete hydrographic and geophysical survey package, including:
Multibeam and single-beam echo sounders
Side scan sonar
A marine magnetometer
A sub-bottom profiler
Full GNSS positioning and inertial navigation
Together, these tools let our crew map the seafloor, subsurface conditions, and underwater hazards in a single mobilization, instead of switching vessels or contractors depending on what a project requires.
For our clients, the value isn't solely within the equipment list. It's also what that equipment makes possible:
Fewer mobilizations. Because Hydro Cat 1 carries every sensor a project might need, clients aren't paying for multiple vessel trips or coordinating between separate specialty contractors.
Reach into water other vessels can't survey. Shallow bays, inland waterways, and nearshore transition zones that stall out larger vessels are well within Hydro Cat 1's operating range.
Dependable data across a wider range of project types. Whether it's a dredging project, a pipeline corridor, a bridge inspection, or a coastal restoration effort, the same vessel and crew can support it, which means fewer handoffs and fewer chances for something to get lost between them.
Fewer weather-related delays and steadier data collection. Hydro Cat 1's moon pool lets the crew lower survey instruments straight through the hull instead of over the side, keeping equipment steady and protected, and letting the crew keep working through conditions that would otherwise slow a survey down.
A survey partner that scales with the job, rather than a vessel that's either underpowered or overkill for what's actually needed.
Hydro Cat 1 Survey Capabilities
Hydro Cat 1 is equipped to support a wide range of hydrographic and geophysical survey work, including:
Hydrographic and bathymetric survey
Side scan sonar survey
Pre- and post-dredge survey
Dock and salvage inspection
Search and rescue survey
Navigable waterway crossing inspection
Pipeline pre-lay and route survey
Shallow hazards survey
Pipeline inspection
Archaeological resource survey
Habitat and seafloor classification survey
Near shore and beach approach hydrographic survey
Site assessments
That range is expansive, but it is exactly the point. Hydro Cat 1 gives our survey team a vessel that matches the work in front of them without compromise or the need for additional boats or contractors. As our hydrographic survey footprint continues to expand along the coast, this is the kind of investment that lets us show up as a true partner, from shoreline to seafloor.
