Holloway Houston is proud to have contributed to the first DNV project in the United States. Through our long established relationship with DNV (Det Norske Veritas), Holloway Houston presently fabricates over 90% of the DNV class slings built in the Western Hemisphere. We perform most of the DNV witnessed pull testing on pad eyes and other weldments, synthetics, and umbilicals of various types. DNV surveyors are on site at Holloway at most given times.
