Scope of work includes procurement of four large bullet LNG storage tanks each with a capacity of 265,000 gallons, an LNG off-loading system, a 1,000’ sub-sea pipeline, and LNG regasification system to supply natural gas to the Navy’s new power plant. Various additional improvements have been recommended by OnQuest including the planned addition of Boil-Off Gas compressors and a flare, as well as other process improvements identified by OnQuest.

Primoris' work on the Naval Station Guantanamo Bay LNG Facility project, included the procurement of four large bullet LNG storage tanks each with a capacity of 265,000 gallons, an LNG off-loading system, a 1,000-feet sub-sea pipeline, and LNG regasification system to supply natural gas to the Navy’s new power plant. Various additional improvements have been recommended by Primoris including the planned addition of Boil-Off Gas compressors and a flare, as well as other process improvements identified by Primoris.

Primoris Design & Construction performed engineering services to revamp the existing Hydrogen Unit to process an off-gas feed stream from the new Renewable Diesel Unit upgrade. The project included adding hydrotreating capability, SMR burner modifications, new instrumentation and Pressure Swing Adsorption unit revamp to allow processing of a RDU purge gas stream for additional hydrogen recovery.

Primoris Design & Construction performed FEL 2, FEL 3, Detailed Engineering, Equipment and Material Procurement and Full Site Construction for expansion of the refinery capacity from 162,000 to 187,000 BPSD. PD&C’s scope included the EPC revamp for two Crude/ Vacuum Units. The No. 1 Crude Unit charge rate was increased by 10,000 BPD from 60,000 BPD to 70,000 BPD and the No. 2 Crude Unit charge rate was increased by 15,000 BPD from 102,000 BPD to 117,000 BPD. The Crude Unit revamp also included a new preflash tower, new charge pumps, and a completely redesigned preheat train utilizing helical-baffled exchangers. An additional 6,000 BPD capacity was added to the Naphtha Hydrotreaters (NHT). Modifications to the NHTs included replacement of the Stripper Feed Pumps and HDS Pumps, Feed Stripper packing, additional Reactor catalyst, high capacity desulfurization trays, and additional air cooling.

Primoris performed the front-end engineering on Yosemite’s Clean Energy renewable biofuels project. The facility will use gasification technology to convert farm and forest wood waste to syngas and ultimately into carbon-negative, green hydrogen and renewable natural gas (RNG).

Primoris’ Energy/Renewables segment will execute the work using our extensive experience in syngas, hydrogen and renewable natural gas production.

Primoris Design & Construction performed FEL 2 and FEL 3 engineering for a Renewable Diesel (RDU) Project. The scope of work included process design development using Haldor Topsoe technology, completion of the FEL-3 design development, and developing the detailed TIC estimate for the new processing facility. PD&C engineering teams worked closely with Haldor Topsoe to provide value engineered solutions for improved operability and cost savings.

Primoris was awarded a contract from joint venture partners to provide a turnkey scope for an initial 100,000 GPD train of liquefied natural gas (LNG), and distribution facility in George West, Texas. The project included engineering, design, supply of equipment/materials, and construction of a 100,000 GPD liquefied natural gas and distribution facility. The plant addresses the demand for a reliable and safe supply of high horsepower fuel to the Eagle Ford Shale basin in Texas.

The plant is designed to compress pipeline quality gas, remove carbon dioxide and water and liquefy the treated gas. Liquefaction is carried out in a cold box using a nitrogen-based refrigeration system designed and supplied by Chart Industries. The product LNG is stored in three 90,000-gallon ASME vessels. The facility has the capability of loading LNG truck trailers. Chart Industries provided cryogenic technology and liquefaction equipment.

Primoris completed the installation of 13K of 4-inch steel to serve the newly built concourse at the Orlando International Airport. This project was completed ahead of schedule and included a customer record HDD 3,470’ shot. (Due to FAA regulations, picture availability was limited.) This project was completed on time with zero injuries or OSHA Recordables.

Primoris completed a new Gate Station build for TECO/Peoples Gas in Wildwood, Florida. This project was a venture between our MSA customer (TECO) and Enbridge. The project consisted of all clearing, ground-up fabrication, installation, activation/commissioning the station and the construction of a “hidden” road. The project lasted for about nine (9) months and could not have been completed without the collaboration between Q3 and PDS. This project was completed on time with zero injuries or OSHA Recordables.

Primoris’ scope was to convert the Greendale neighborhood to 24.9kV system, install 7.8 miles of underground primary cable, install 1 mile of new underground secondary cable, transfer all customers to the new system and remove 4.5 miles of existing overhead distribution lines. The project was very successful, customer satisfaction was very high, our field leaders worked very diligently to schedule and coordinate all work and outages with local customers to limit disruptions and accommodate special needs. We worked closely with the owner and state agencies to develop schedules that could be accommodated by the locating group.
