ABOUT

Troy Williams - Chief Executive Officer

Paul Gariepy - Chief Operating Officer

DEAN Mission  DEAN is dedicated to providing high quality service, equipment and personnel in a safe, efficient, consistent and professional manner.

Value Proposition  DEAN provides our customers with the rapid deployment of a well-positioned suite of specialized equipment; knowledgeable personnel with extensive pipeline and remediation experiences; and solution driven processes and applications to alleviate the risks associated with pipeline assets in a safe, environmentally sound and cost-effective manner ensuring effective execution, timely flow assurance and maximum uptime.

Company History  Dean was founded in Louisiana by Mr. Troy Williams in 1992 with the purchase of two cranes, which he subsequently leased to a local contractor. Since that time, the Company has grown into a leading, Tier 1 provider of midstream pipeline integrity services to some of the largest oil and gas pipeline operators in the U.S.

The acquisitions of G&G Marine and Coastline added complementary services and enabled the Company to offer complete pipeline integrity projects with limited, subcontracting requirements. While Dean and both acquired companies are separate legal entities, the acquired companies effectively operate as wholly owned subsidiaries of Dean.

 

PROJECTS

LAKE WAURIKA PIPELINE

Pipeline operator had a called internal anomaly, that had to be investigated. The pipeline was in a inland drinking water reservoir with 7 feet of mud cover and 19 feet of water with 5 ½” concrete coating. We had the task of connecting portable barges together, load crane, deep water caisson along with many other pieces of equipment needed to expose pipe. Once pipe was exposed  concrete was  removed, pipe was then sand blasted. NDE then performed evaluation of defect, once evaluation was  complete repair method was to install type B sleeve, pipe was then coated and site was then backfilled to previous cover.

PROJECT NEW PIPE INSTALLATION

Dean Companies was awarded a project in Larose, LA to install 4500’ of new 14” pipeline to replace a vintage 18”. All spool pieces were prefabricated in Deans yard in Harvey and coated to operators painting specs.  Launchers and receivers were removed and sent to the Harvey yard for modifications and returned to service.  Entire system was hydrotested prior to running caliper pig through new 14” pipeline. Installation consisted of 2 directional bores beneath navigable waterways. All civil work was completed by Dean for the foundation and pipe supports for all new equipment. Project was completed ahead of schedule with no accidents or injuries.

CAISSON BOX REPAIR ON GOLDEN RANCH

Dean Companies was awarded a pipeline integrity project to investigate an anomaly on a 14” pipeline that was called out during an in-line inspection performed by the operator. Repair was completed in a small canal in a sensitive environment due to landowner requirements for the property. Dean accessed the property with 3 barges and tugs with associated equipment to safely complete the repair. Pipeline was exposed inside of the caisson box and anomaly was graded to determine the proper repair method. Welders installed a full encirclement sleeve after instructions from operator’s integrity group.  Area was returned to proper condition and all equipment removed from the location. No accidents and injuries.
