Electrical & Instrumentation Engineering

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 and detailed engineering for the OSBL portion of restarting the coke conveyor unit at a refinery. Keystone’s scope included performing a 3D laser scan and assessing the existing structural steel and foundations which previously supported a 24” wide conveyor and providing detailed design for all necessary upgrades to support the installation of a new 36” wide conveyor in its place.

Additionally, Keystone provided detailed civil/structural design for a new coke crusher at the north end of the conveyor, as well as detailed electrical and instrumentation engineering.

Keystone performed multi-discipline engineering, project management, and design services to restart an ethylene cracker located in Sulphur, LA. Keystone’s scope involved moving propylene, CC4, and pyrolysis gasoline from the facility. Keystone designed a new railcar loadout system with a control building and truck loadout station to supplement the existing infrastructure.

The design featured two multi-product loadouts, four propylene loadouts, and one driver-interfaced truck loadout station. Keystone designed a new railway pipe rack that connects existing storage and transfer pumps to the new railcar loading stations and extends to the truck loading area. The facility design included a new control building, housing the PLC and HMI control systems, offices, break room, and washroom.

Additionally, the engineering scope included refurbishing/modifying the flare and relief systems, existing utilities, I&E, and interconnecting piping for new and existing equipment. Keystone performed PHA, LOPA, and SIL studies on all systems.

Keystone provided engineering and detailed design for the support structure and lattice tower for the meteorological tower for a 268 MW offshore wind farm in Maryland. The intricate steel lattice tower is approximately 330 feet (100.6 meters) in height and is supported with a braced caisson foundation. Keystone’s scope of work included conceptual and detailed design of the substructure and tower, electrical subsystems design, mechanical subsystems design, project management services, on-site fabrication support, bidding documentation prep, and installation strategy support.

Keystone provided project management, engineering, and design services for a New Change House at a food grade chemical manufacturing facility. The design included a new 40’x50’ metal building with a 4’ walkway on three sides, a divide for a men’s and woman’s side, and a dry and wet area with showers and restroom facilities. Keystone’s scope of work involved a complete drawing package that included plans for the site prep, plans and details for the foundation of the new building, plans and schedules for all mechanical and plumbing items, and plans and details for the layout of the exterior and interior building sections.
