Hydrographic Survey DimCon

Paisano Dimensional Control offers dimensional control (DimCon) surveys for commissioning hydrographic survey vessels of all kinds.  We provide offset/lever arm surveys and calibrations for Gyro, IMU and DGPS systems against ground points using grid coordinates.  

As standards in marine surveying get tighter, precision is paramount. Hydrographic survey vessels, responsible for mapping the seafloor, measuring water depths, and gathering data on submerged features, require precise tuning and alignment to ensure that their operations are accurate and reliable. Dimensional control surveys play a crucial role in establishing and maintaining the accuracy of data these vessels produce. These surveys ensure that the vessels’ physical structures, instruments, and positioning systems are aligned and calibrated to meet the rigorous standards of the hydrographic survey industry.

When commissioning of a new hydrographic survey vessels or changing/installing additional sensors it is vital to verify the exact position of each of these instruments relative to the vessel’s coordinate system based on the hull.  Centerline of the vessel is established in dry dock from the keel or quayside from the wheelhouse or mast and the center stern.  The Z plane is measured with points around the deck.  All offsets are then relative to this coordinate system.  This will ensure that the survey data collected will be as precise as possible and it greatly reduces the time necessary to complete GAMS and patch testing.  DimCon also makes alongside nav checks and sea trials necessary to be completed much quicker to gain vessel acceptance from the client.  This helps our customers bottom line by reducing overhead days before they can go on contract.

Using high precision 1 arc second Leica total stations with Spatial Analyzer metrology software, it allows us to work on the vessel quayside pitching, rolling and unleveled and still provide 1mm accurate feature offsets/lever arms in the same coordinate system.  We use 4 – 6 GPS static control points on the dock to establish a network of grid coordinates that we use to carry out Gyro and DGPS verifications.  Heading, Pitch and Roll verifications are completed with two total stations taking simultaneous shots synchronized to GPS UTC time so data can be compared to time stamps from vessel logs.  In most instances we are able to provide all C-O corrections before we leave the vessel. Our goal is for the boat to go to work as soon as possible after we complete our scope of work for the DimCon vessel calibration.

Our experience ranges from drill ships all the way down to side scan tow fish.  We can assist with all size boats, ROVs, AUVs, USVs, etc., whether quayside or in dry dock.

Paisano Dimensional Control uses precision survey equipment and metrology software to capture and interrogate data.  Survey reports are provided to client and crane inspectors for review and we can assist with making adjustments and repairs as needed.  We can also provide as-built surveys to record successful adjustments and provide a baseline for future survey reference.

Precision Mapping for Projects That Matter

When you’re planning a project that intersects with water—whether it’s for construction, navigation, environmental protection, or energy development—you need accurate data you can trust. At Paisano Dimensional Control, we offer Hydrographic Survey DimCon services that bring clarity, confidence, and actionable intelligence to your decision-making. Our team isn’t just running a sonar and handing over a chart. We’re in the business of delivering answers, revealing the unseen, and guiding your project with unmatched precision.

We know how much is riding on getting it right. That’s why we take pride in being more than a vendor—we’re your partner in progress.this system in place, the collected data is as accurate as possible, enabling quicker completion of essential tests like GAMS and patch testing.

Why Hydrographic Survey DimCon Is Essential to Your Project

If your project touches water, it touches risk. Shifting seabeds, unpredictable depths, submerged hazards, and regulatory requirements can all create costly delays if not accounted for properly. With our Hydrographic Survey DimCon services, we strip away the unknowns. We deliver detailed bathymetric data and underwater topography so you can plan smarter, execute faster, and stay compliant every step of the way.

We’re not just talking about “good enough” data—we’re committed to exactness. That’s the DimCon promise. From rivers and lakes to coastal zones and offshore sites, we tailor our services to your unique environment and objectives.

Built on Accuracy: What Sets Hydrographic Survey DimCon Apart

There are plenty of ways to collect hydrographic data, but at Paisano Dimensional Control, we believe how it’s interpreted, processed, and applied makes all the difference. With us, you don’t just get a service—you get a solution.

When you hire us for Hydrographic Survey DimCon, we become an extension of your team. We work in real-time, adapt to site conditions, and never lose sight of your end goals. The technology we use is state-of-the-art, sure, but it’s our people who turn that data into insights that actually help you make informed decisions.

We understand the language of the water—its patterns, behavior, and influence on your structure or system. That understanding informs every scan, every chart, and every conversation we have with you. That’s the difference DimCon brings to the table.

Confidence Below the Surface

Water hides things. That’s its nature. But with Hydrographic Survey DimCon, we give you the confidence to move forward as if everything was laid out in the open. When we perform a survey, we’re uncovering layers of information that protect your investment, your people, and your timeline.

It’s about more than just maps. It’s about control—control over variables, control over outcomes, and control over your budget. We’ve helped clients across industries gain a clearer picture of what’s beneath them, whether it’s to place a pipeline, anchor a dock, inspect dredging impact, or establish a construction corridor.

We Work Where Others Hesitate

Some survey teams shy away from challenging conditions. Not us. Our team is built for complexity. In fact, we thrive in it. Whether it’s shallow water, tidal interference, or areas with heavy vessel traffic, our Hydrographic Survey DimCon approach is designed to meet the moment.

From freshwater reservoirs to turbulent marine zones, we apply our decades of experience to assess every challenge head-on. We don’t believe in cookie-cutter solutions. We believe in craftsmanship, attention to detail, and taking the time to understand what success looks like for you.

That’s the Paisano way—and it shows in our results.
