Since 1989, STV’s experience in the oil and gas industry has included pipeline and facilities projects that encompass planning, feasibility studies, permitting, FEED, detailed design, and construction management support services. We have assisted our pipeline industry clients with new cross-country pipelines, existing pipeline relocations, drilled crossings, environmental issues, obtaining and coordinating routine and difficult permits, providing traditional as well as innovative technology designs, and supplying construction assistance from field surveys to complete construction management services. STV is experienced in liquids, natural gas, liquefied petroleum gas (LPG), petrochemical, and two-phase flow pipeline systems. STV is adept in the planning and design of pumping and compressor stations, terminals and manifolds, tank farms, cryogenic gas plants, receiving and delivery stations, maintenance facilities, and associated infrastructure.
Liquid Petroleum Product Pipelines
STV’s long-term relationships with major U.S. petroleum companies comprise all aspects of the business including capital development, maintenance, integrity management, third-party encroachment, pipeline relocations, and new business ventures. Our experience encompasses complete life-cycle assistance from conceptual engineering, initial studies and pipeline route planning, through front-end and detailed engineering design and project management, to equipment procurement assistance and post-design services. We have supported our pipeline industry clients with new cross-country pipelines and pipeline relocations, providing traditional as well as innovative technology designs and supplying construction assistance from field surveys to complete construction management services. A leader in using trenchless technologies when feasible or environmental conditions warrant, we perform all environmental services with an in-house staff of regulatory specialists and scientists who excel at obtaining and coordinating routine and difficult permits.
Natural Gas Pipelines
Even before the recent discovery and exploration of the shale natural gas reserves, STV has had a long history of working with the natural gas industry. As part of our utility natural gas energy services program, we recently completed several major utility companies’ pipelines and facilities required to convert their major Mid-Atlantic power production to natural gas, successfully planning, permitting, selecting the routes, and designing the pipeline interconnections and related facilities.
We complement our utility business with servicing the build-out of the pipeline and facility infrastructure accommodating the unconventional natural gas midstream plays across the country, including the Marcellus, Permian, Eagle Ford, and Bakken developments. Our wide range of services in support of the unconventional gas plays includes project/program management, pipeline route studies, feasibility studies, preliminary engineering, environmental permitting, final design, and construction support. With decades of experience working for gas and oil companies in these regions, we are well-versed in managing the logistics and obtaining timely approvals from the local, state, and federal environmental regulatory agencies.
Liquid and Gas Facilities
STV provides engineering and design services for pump metering and blending facilities, as well as for the installation of instrumentation systems, custody transfer metering and blending facility projects. We are equally adept in the planning and design of pumping stations, terminals, tank farms, plants, receiving and delivery stations, administrative and maintenance facilities, and associated infrastructure improvements.
As part of the development of the shale plays and gas gathering systems, clients require specialized facilities to process the gas to be used on the market. STV has expanded our natural gas facilities capabilities from compressors, metering, traps, dehydration, and accompanying facilities to more complex facilities, such as gas processing plants, water injection facilities, gas treating plans (H2S and CO2 removal), natural gas liquids (NGL) recovery, stabilization, fractionation, liquids storage, acid gas disposal, and wellhead facilities.
Horizontal Directional Drilling (HDD) Projects
STV has participated in numerous design projects where HDD was used to install new pipelines beneath major waterways, railroads, and highways. STV has provided the full range of environmental, engineering, and construction management services for these projects, including several recent pipeline projects in Ohio. Our recently completed 160-mile Allegheny Access pipeline project for Sunoco Logistics involved 62 HDDs (with all segments totaling 109,000 feet) and 161 auger bores. We have also worked with regulatory and transportation agencies, including the U.S. Army Corps of Engineers, to demonstrate the advantages that HDD offers as a construction method.
Environmental and Engineering Agency Permits and Approvals
STV excels in performing the technical studies required to secure environmental- and engineering- driven local, state, and federal permits and approvals for linear and related facility projects. We are also adept at the acquisition of engineering-driven approvals such as local, state, and federal highway crossings; water, electric, and utility impacts; railroad crossings and parallel occupancy, as these represent critical components in the project approval process. Employing proven permitting methods, STV routinely partners with our clients’ environmental compliance program initiatives to improve the process as specific assignments and implementation details become available. Experienced in building long-lasting and effective working relationships with agencies having purview over the projects, we effectively fulfill their expectations and requirements, applying regulatory-compliant and defensible science to each project. STV’s execution strategy has proven to be successful for those permits and approvals traditionally encountered in the course of capital, maintenance, and regulatory-driven projects and programs.
