Sulfur Unit Rebuild and Upgrade

St Croix, U.S. Virgin Islands

YEAR 2019

TIC $ 82m

Upon the completion of the refinery restart project, the Limetree Bay Refinery will be capable of processing around 200 thousand barrels per day.

 

Key restart work at the site began in 2018, and the refinery is expected to resume operations in late 2019. Refinery units will include the 62 thousand barrels per day modern Coker Unit, extensive Desulfurization capacity, and a Reformer Unit to produce clean low-sulfur transportation fuels that will meet International Marine Organization Standard required under international law in 2020.

North Flare and Firewater Upgrade

Big West Oil - Salt Lake City, UT

YEAR 2019

TIC $ 78m

This effort represents a program portfolio of projects that we constructed during the same time frame. There were multiple objectives to achieve, coordinate and maintain alignment.

The projects included: new flare (in a new location), a new firewater tank and pumping system, a new plant compressed air system and a reverse osmosis system. These projects required many miles of pipe, electrical circuits and support structures.These projects impacted multiple locations across the site and required a layout spanning many acres.

The complexity project was increased because of the number of engineering firms, vendors and contractors involved. The technical solutions were straight forward, but integrating them into the existing process facility and across the large area provide more than a few challenges.

Wet Gas Compressor Upgrade

Big West Oil - Salt Lake City, UT

YEAR 2015

TIC $ 32m

The project objective was to replace the existing wet gas compressor which was near the end of its economic lifespan. The new system had to be located in a new location, allowing the operation of the existing unit during construction. The new system included a steam driven Turbine, Gear box, Lube oil skid, suction drum and the relocation of the refurbished existing compressor.

The initial design phase included a Lidar Scan and model of the existing system and the location for the new system. The design team develop three layout options for conceptual review. During the conceptual review input was provided by the operations, maintenance, construction and the safety team members and a final option was selected. The procurement and construction coordination was complex because of the number of vendors and tight tolerances.

The project success was due to a team of individuals focused on the project objectives.

Diesel Stripper Column Replacement

Big West Oil - Salt Lake City, UT

YEAR 2017

TIC $ 93m

The initial objective was to replace the existing diesel stripper column in the crude unit. As the project progressed through the development stages the scope increased to include replacement of the three columns and the demolition of an existing vacuum unit which had been retired. 

The demolition had to occur prior to detailed design because underground obstruction locations had to be verified. During detailed design, layout and orientation of all the components were considered in addition to future expansion needs.

​

The design and layout was developed in 3D, both above and below grade to avoid obstructions.Deep pier foundations were required because of the soil conditions in the area, these were installed at the onset of winter. The fit-up of the steel structures and piping was almost perfect (one clash between two pieces of uni-strut), we appreciated having a team of designers, fabricators and contractors that worked very well together.
