Geo-Marine Technology Experience

Reliably providing exceptional services to the offshore energy and telecommunication industries since 1997

Whether measured in years or line kilometers, Geo-Marine Technology, Inc.’s wealth of experience serves as the foundation of its commitment to interpretive excellence.  Since the beginning, we have undertaken a broad variety of projects that are unique and challenging, and our clients frequently return to us for solutions to unusual problems.  We strive to stay on the cutting edge of technological advances, and the software we use allows us to continually develop new analytical techniques.  Although we will use every means at our disposal to extract meaning from a data set, we will not proffer any conclusion or recommendation we cannot defend.  Our products therefore reflect the highest ethical standards for data analysis and interpretation, and our reputation reflects our commitment to those standards.

Our reports are produced in DOC(X) and PDF formats, and are available in electronic files and hard copy.  Charts and maps are produced in AutoCAD and PDF formats, and come with fully-attributed, Makai-compatible electronic files.  All of our products comply with International Hydrographic Organization (IHO) standards and with the industry-standard hazards/archaeological survey reporting requirements set forth by The Bureau of Ocean Energy Management, Regulation and Enforcement (BOEMRE) in NTLs 98-20, 06-P01, 2008-05, 2007-G01, 2009-G30 as well as UKOOA charting and reporting Guidelines (2008).

John Rietman
After 20 years at the helm of GMT and a substantial portion of the holocene in the marine geoscience industry, "Reety" is still going stong. His work ethic, intelligence and willingness to help both our clients and employees attain their goals have been instrumental in shaping the company into what it is today. Without his ingenuity, drive, humor, and professionalism, we'd be like a ship without a rudder, or a sonar without a topside! Cheers to many years of making positive waves in the industry, and all you do for the company, John!
