Procurement

Keystone provided project management, engineering, and design services for the expansion of a pipeline terminal, including the installation of a new 80,000 barrel tank and additional rail offload for ethanol storage, as well as a new eight inch transfer line. The existing ethanol rail offload was expanded to add spaces for another 20 cars, including the all rail infrastructure with containment, safety equipment, pump capacity upgrades and capability to provide product to an existing tank, the new 80,000 barrel tank, and provide flow to the new transfer line.

Additionally, a second facility takes deliveries from the pipeline and includes storage for all of the products (gasoline, diesel and ethanol, etc.). This facility was given the accommodations to fill transport trucks for delivery to customers using two separate additives, which provides the required lubricity additive for the ULSD and uses a VRU as the required vapor control unit for the truck loading area.

Scope of Work also included: composing performance specifications and assisting with procurement of railcar expansion, storage tank and electrical switchgear/MCC, 4-bay truck loading station, four new buildings, 6 new tanks, VRU system for the terminal/truck loading, fire and gas safety system for the terminal, ethanol blend skid, evaluating utility systems, modifying containment and drainage systems, and specifying equipment including: railcar offload pumps, transfer pumps, manifolds, and meters.

Keystone provided project management, engineering, design, and procurement support services for the detailed engineering and design of five facilities associated with the Delaware Basin Crude Pipeline, including brownfield modifications to four existing sites and one new greenfield site. The pipeline consists of 40 miles of 16" pipeline, 105 miles of 24" pipeline with a designed flow rate of 150,000 BOPD, and expansion capability up to 200,000 BOPD.

Keystone's scope of work included Coriolis meter additions, booster pump & mainline pump additions at three brownfield sites (18,000 total HP), greenfield pump station with one 200k BBL storage tank and provisions for five future tanks, and reinforced concrete foundations with above ground supports. The scope also included I&E tie-ins to new-build PLC & power infrastructure, MLV sites, pig launchers & receivers, 480VAC three-phase utility power drop, and communications (VSAT w/ cell phone backup).

Keystone provided project management, engineering, and design services at a greenfield and existing site in South Carolina for the installation of additional compressors. The project goal included increasing the overall pipeline capacity.

The brownfield compressor station expansion added new compressors to increase capacity from 150 MMSCFD to 300 MMSCFD. The scope of work included the installation of new separation vessels, coolers, and fuel gas coalescers. The greenfield site included installing a Solar Saturn turbine with centrifugal compressors for 175 MMSCFD with separation vessels, compression coolers, and fuel gas coalescers. Additionally, Keystone provided procurement, bidding, and permitting support services for this project.

Keystone provided project management, engineering, and design services for the detailed engineering design of the Orla Gas Gathering System located in West Texas and New Mexico. The project included installing a gas-gathering system to collect hydrocarbons from multiple Customer Delivery Points. The scope of work involved installing a new 600 MMSCFD gas-gathering system, including 35 miles of 24" ANSI 600# gas pipeline, five surface meter/tie-in sites, and three surface receiving/metering sites. More specifically, all associated foundations, supports, piping, and I&E interconnects.

The pipeline scope of work included hydraulic calculations and material selection, API 1102 crossing calculations, HDD design, and interface with surveying for plat and alignment sheet development. Keystone also served as a primary interface between the client, third-party contractors, and all export pipeline operators. The receiving site was capable of 850 MMSCFD with a pipeline designed for 600 MMSCFD.

Keystone provided multi-discipline engineering and design services for a major project to install a $125MM new Alkylation Unit. The design basis of the new Alkylation Unit involved utilizing an existing decommissioned unit at another site. Nine pieces of equipment at that site were refurbished and reused for this project, including a refrigerant compressor, contactors, and six pressure vessels. One reboiler/heater, three towers, ten tanks, 11 heat exchangers, 21 drums, and 49 pumps were specified, purchased new, and installed. The additional connected electrical load required an addition of electrical substation and DCS control expansion including 800 new instruments. Additionally, the project implemented new cooling towers and instrument air compressors to expand existing facility utility infrastructure to support the process unit installation. An existing LPG Truck Loading Rack was demolished to create room for unit installation and a new LPG truck loading rack was engineered to support facility with safety interlock updates.

To support an increase in the Sour Water System's capacity, Keystone provided project management, engineering, and design services for the FEL 3 and detailed design phases of the project. The new system design included a capacity of 120 GPM sour water charge and 40 GPM turndown case.

The scope of work for the new Sour Water System Unit included sour water feed pumps, sour water feed/product exchangers, stripper tower, pump around pumps, overhead cooler, sour water reboiler, tempered water pumps, and a sump pump. Additionally, the new unit tied into steam, instrument air, and power systems.
