Design of 44 mile, 30 inch gas transmission pipeline - Northern California

GTS performed the pipeline route study and engineering design for a new PG&E 44-mile gas transmission pipeline crossing the San Joaquin Valley to serve the residential and commercial load growth in South Sutter, West Placer, Sacramento and El Dorado Counties. Three potential pipeline corridors were identified and broken into segments. Using a computerized decision matrix, the preferred route was determined by comparing the environmental aspects, public impact, land use compatibility and constructability of each segment. GTS prepared the preliminary environmental impact reports and managed the CEQA process to successful completion. GTS also developed the construction cost estimates for the recommended route.

Due Diligence for Purchase of Collection System

GTS performed the due diligence review on 65 miles of the Rio Vista Collection System that was ultimately purchased by Rosetta Resources from PG&E.

This included assessing the condition of the piping system and records, cost development for bid offering economic/financial feasibility, determining connection points, and identifying system modifications. Also assessed the resources necessary for operation and maintenance of the acquired system.

Subdivision Applicant Design

As a provider of new business applicant design services, GTS produces high quality designs that meet the requirements of the CFR 49, Part 192, the CPUC and the local utility. The final job package is accurate, constructible, and delivered in a timely manner, allowing developers to meet their construction milestones.  GTS provides this service for over 6,000 gas commercial, residential, and multi-family dwelling units, representing over 100 projects ranging in size from 5 to over 300 lots and buildings each year. This includes the design of over 50 miles of new gas distribution main ranging in size from 1 inch to six inch, in both plastic and steel.  GTS has also provided electric design and joint trench coordination and preparation for over 600 residential lots.

Private 7.5 mile Pipeline through Rugged Terrain

GTS completed the design work and project management functions for this pipeline, which consists of 6.7 miles of 4” pipe operating at an MAOP of 975 psig, a plastic distribution system, and 4 meter sets. The pipeline and distribution system serve the Casino, a new 300-room hotel, a 2 MW Cogeneration facility, and several other facilities associated with the resort.

Propane Distribution System

GTS provided engineering, procure and construct (EPC) services for a propane distribution system for the Rumsey Rancheria Indian Tribe at Cache Creek. The system consists of a redundant propane vaporization system, an 18,000 gallon underground storage tank, gas distribution main and service facilities designed for both propane and natural gas, and automated meter reading. GTS provided the design for the piping and mechanical system, obtained all the material, and contracted and managed the construction.

Hydro-Test 36-inch diameter in Sensitive Environment

GTS was contracted to supply consulting project management services for the hydro-testing of 3.5 miles of 36 inch OD natural gas transmission pipeline to qualify for a class location change from 1 to 2. Testing required the extraction of 950,000 gallons of water from the Fall River in Shasta County California. The test water was treated through carbon filters prior to release into the river. GTS was responsible for developing the project schedule, cost monitoring, and status reporting for the project from start of engineering to construction completion.

Inter-tie Station Design and Construction Management

GTS provided engineering, design and construction management services to modify station piping and install a by-pass valve at SMUD's transmission inter-tie with PG&E The by-pass was installed to facilitate testing and operation of a 20-inch diameter controller operated main line valve. GTS created the construction drawings, and clearance documents for the project. The clearance included shut down, by-pass and tie in procedures to insure continuous service during construction. GTS provided a construction specialist to direct SMUD construction crews.

Integrity Management Program Development

GTS is developing the integrity management program (IMP) for Sacramento Municipal Utility District (SMUD). The integrity management program is necessary to comply with the recent Pipeline Safety Improvement Act. The GTS tasks include: Identify High Consequence Areas, Perform required risk management studies, Recommend methods for integrity assessments, Draft the comprehensive integrity management program, Update SMUD procedures and standards affected by the IMP, and integrate the IMP into SMUD's new GIS system.

Owner Engineer 26 mile 24-inch - Sacramento, CA

GTS provided a pipeline route study and recommendation for a natural gas pipeline to serve the proposed 500 MW Cosumnes Power Plant. Three corridors were identified for the most viable routes. The corridors were compared by use of a decision matrix that considered Environmental, Public Impact, Compatibility of Use, and Constructability impacts. GTS also developed a conceptual design and construction cost estimate for the recommended route.

Gas Gathering System Replacement Analysis

GTS provided a conceptual design and associated cost estimate for the replacement of the Rio Vista Gas Gathering System in California. The cost estimate was used to support negotiations for the purchase of the existing system from PG&E. The conceptual design consisted of Gathering Pipelines, Dehydration, and Compression Facilities to gather approximately 50 MMscf/d of natural gas production.

Technical Guideline Development and Training

GTS developed three technical guidelines: Right of Way Patrol, Exposed Pipe Evaluation, and Water Crossing Inspection. GTS provided expert opinion and industry research for the development of the guidelines. In addition, GTS provided training to Koch patrolmen and engineers regarding the new guidelines.
