DNV Certification

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 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.

We understand how important it is for our clients to carry out safe operations at their sites. Holloway Houston, Inc. has DNV 2.7-1 and DNV 2.7-3 type approval certification from DNV. With us in your corner, you’ll never have to worry about any safety aspects.

Carrying the DNV certification means our products are in proper compliance with national and international standards. The DNV certification programs we provide enable high-level quality performance that is in accordance with customer requirements.
