Fabrication QA Power Generation Representative Projects

The Lake Hodges Pipeline and Hydro Electric Pump Station is a part of San Diego County Water Authorities Emergency Storage project. Hydraulic turbines will provide the additional benefit of capturing energy created when water flows from the Olivenhain Reservoir into Lake Hodges. The pump station will generate 40 Megawatt capacity by utilizing 2 each 20 MW (15300 HP) vertical generators. This very important project will increase the amount of water available within the county for use during emergencies. The work being performed consists of the construction of new pump station and inlet outlet structures, installation of fabricated steel pipe and fittings, and related systems, gates and valves, and other appurtenances. On-site Technical Services Inc. is providing shop fabrication inspection services of the mechanical equipment and large diameter steel pipe and fittings associated with this project at various locations both domestic and China, Brazil, and Canada.

Rancho Peñasquitos Pressure Control and Hydroelectric Facility located in the Mira Mesa area, will serve an important function in improving aqueduct operations and enhancing the flexibility of the Water Authority's extensive water delivery system. A 4.5-megawatt hydroelectric turbine generator will generate supplemental electricity in the facility and will operate year-round, reducing the Water Authority's energy costs while supplying surplus power to the region. The construction of this $21 million facility consisted of the manufacture of 3,000-feet of 96 inch-diameter and 108-inch-diameter pipe at numerous locations throughout Korea that will connect the facility to existing pipelines. On-Site Technical Services provided inspection of the large diameter pipe, fittings and coating inspection at locations throughout Korea and the United States. Fabrication inspection of the engineered equipment such as the pumps, valves and turbines will be inspected at various worldwide locations.

SDG & E's Palomar Power Plant expansion involved the upgrading and replacement of mechanical and electrical equipment throughout the plant. On-Site Technical Services provided direct technical support and engineering analysis, fabrication inspection services, supported performance testing and vibration analysis of 3 each 65,000 GPM 1,750 HP Vertical Pumps fabricated in the United States and Mexico. Due to the critical time line associated with the installation of the equipment On-Site Technical Services provided expediting services during the fabrication of the pumps and components to ensure that the pumps arrived at the job site meeting customer specification requirements prior to shut down and installation of the equipment. On-Site's staff provided inspection and engineering support during the performance testing of the pumps.

Los Angeles Department of Water and Power Palomar Power Plant expansion involved the upgrading and replacement of mechanical and electrical equipment throughout the plant. When the installed 42" pumps began making cyclic noise and vibrating during operations On-Site Technical Services was contacted to perform engineering analysis of the problems associated with 4 each 45,000 GPM, 750 HP Vertical Pumps. These efforts involved the failure analysis of the pump components, supporting the rebuild efforts and start up operations of all 4 pump units.

Ishikawajima Heavy Industries Tangjun Bin Power plant is a Coal Fired Power Plant capable of producing 21,000 MW of energy per year. This plant which, is currently under construction is located in Malaysia and is being constructed using technology that will efficiently utilize their limited natural resources. On-Site Technical Services is providing Quality Assurance fabrication inspection of the mechanical, electrical and engineered equipment such as the ash systems, compressors, fans, blowers and control panels at locations throughout North America.

In the summer 2009, Kiewit Power Constructors Co., completed a 400-megawatt simple cycle power plant with four GE LMS100 natural gas-fired combustion turbines. This project is important to California's need for peaking power during the demanding summer months.

On-Site Technical services supported the Panoche Energy Center project team by providing Quality Assurance Services during the fabrication of the Circ water pumps which were fabricated in Mexico. On-Site inspectors completed numerous visits to the fabricator to monitor progress, confirm quality and witness the testing of these large pumps.

The Mossyrock Dam and its Two-200 Mega Watt generator units were commissioned in 1968 and are part of Tacoma Power's largest Hydroelectric electricity generating facility that generate about 3 billion kilowatt-hours of electricity each year. The powerhouse contains two generating units and has a total installed capacity of 300 MW. The 2 generating units account for 40% of the Cities power generating resources and have been in service for over 40 billion kilowatt hours. Tacoma power started a project to rebuild these units to increase efficiency with an estimated cost of $50M. As an owner representative On-site Technical Services Inc., is providing shop fabrication inspection services of the mechanical equipment involving the Francis Turbine runner replacements (200 MW and 175 MW capacities), Turbine wicket gate replacements. This project was being manufactured at numerous locations including India.
