Abdon Callais Offshore, LLC may have charted a course through deep waters, but its commitment to strong family values keeps it on an even keel. Kate Sawyer reports  More than a half century has passed since old Abdon Callais had the inspired idea to convert his barebones shrimp trawler into an offshore service vessel. Since that moment, family-owned and -operated Abdon Callais Offshore has employed the best talent and equipment in the service of far-flung oil and gas rigs in the Gulf of Mexico.
