Sample Stations Designed and Installed to Resolve Deficiencies


System design, procurement and construction support for sample stations




Our client, the second largest refinery in the U.S., surveyed more than 700 existing sample stations in their various refinery units and discovered that over 400 had environmental and/or safety deficiencies. The client prioritized the stations according to the severity of the concerns and called on ENTRUST Solutions Group to execute engineering, design, procurement and construction for the $31 million project to replace deficient sample stations.


The sample stations, which were located in every production unit of the refinery, had to be replaced while the refinery was in operation, or during scheduled turnarounds. In addition, many of the sample stations were high priority and required demanding replacement deadlines. The design team demonstrated flexibility by responding to ongoing changes in priorities, turnaround schedules, operational needs, and safety concerns throughout the project.


A dedicated team was embedded at the client’s site to work with plant personnel and executed the project from concept to installation with additional support from ENTRUST Solutions Group employees across the country. The team collected the necessary information and developed detailed plans to install the sample stations. The required documentation included P&IDs, data sheets, isometric drawings, installation details, operational manuals, and spare parts lists. ENTRUST also developed purchasing and tracking specifications for the procurement of each sample station and purchased $1.4 million in materials and equipment. Following procurement, the ENTRUST team provided field construction support. The project required more than 35,000 hours, and the 400 sample stations were designed, installed, and operational ahead of the challenging deadlines.

Many of the sample stations were high priority and required demanding replacement deadlines.
