DOT-COMPLIANT · ON-SITE EMPLOYER DRUG TESTING
Houma, LA Mobile Drug & Alcohol Testing
Offshore Oil Services · Bollinger Shipyards · USCG Marine · Helicopter FAA · Terrebonne Parish — Mobile collections at the offshore industry's southern gateway.
Houma is the operational base for South Louisiana's offshore marine fabrication and oilfield service industry. Bollinger Shipyards, Gulf Island Fabrication, and dozens of marine fabrication yards line the bayou waterways of Terrebonne Parish — building offshore platforms, jack-up rigs, and specialty vessels. Helicopter operators (PHI, Bristow) run crew transfer flights from the Houma-Terrebonne Airport to Gulf platforms. The Intracoastal Waterway and bayou access routes require USCG compliance. OnSite Employer Testing dispatches throughout Terrebonne, Lafourche, and St. Mary parishes — to shipyard gates, heliports, and crew change facilities.
OnSite Employer Testing coordinates mobile drug testing collections at your Houma-area facility, yard, terminal, or job site. We do not operate a clinic. Review how it works or browse all locations we serve across the region.
