Specialty Services:

Hydrographic Surveying – Complete services from deep open water to shallow marsh areas.   Modern automated equipment available includes Precision Dual Frequency Single Beam Systems.   Multibeam surveys also available on short notice.   Positioning systems available include Survey grade DGPS, RTK and Robotic Range Azimuth, depending on project needs.   Over 20 years of experience assures accurate and defendable results .

Side Scan Sonar – Complete near shore and shallow services utilizing compact digital dual frequency side scan equipment suitable for most applications.   If needed, can be fully integrated with hydrographic survey system for simultaneous data collection.   Useful to find obstructions or debris that may be located within work areas.   Also ideal for locating smaller submerged objects or obstructions.

Sub Bottom Profiling – Complete services utilizing digital low frequency system capable of being integrated with real time hydrographic survey systems.   This allows for coordinately correct data to be collected in conjunction with other data types allowing direct comparisons.   Identify distinct strata layers that may lie deep beneath the benthic layer.   This is often very useful in environmental remediation projects.

Vibra Core Sampling – Providing nearshore and inshore services to core suitable bottom sediments for general categorization and contaminant analysis.   Also very useful to verify sediment cap thickness.

Various Geotechnical Services -   Provide positioning and collection assistance as well as support vessels for geoprobe, split spoon or other larger scale marine geotechnical projects.   Also perform grab sampling, push probes or jet assisted probes to ground truth dual frequency data collected or sub-bottom profiles.   This is extremely valuable in remediation projects.

Underwater Video – Able to provide video that is interlinked with actual positioning to aid in site investigations, salvage, recovery   and structural engineering investigations.

Dredge Positioning System Installation and Integration – Install, calibrate and maintain the latest dredge positioning systems.   In particular, setting up hydraulic excavators with fully automated real time positioning.     All other dredge types dealt with as well.   Not just installation and calibration, but real, effective and efficient tailoring of techniques to complete the project within the strictest constraints.   Don’t find out after you start a project that you hadn’t accounted for certain variables or have been dealing with erroneous data.   We will assure that your project gets off on the right foot and will train your personnel if required to assure that it is successfully completed.

Salvage and Recovery Operations - practical experience in salvaging and recovering sunken vessels and other various items.   Can provide assistance with means and methods of recovery, rigging scenarios, locating items, etc.
