Project Description
Otter Tail Power Company’s (OTP) Astoria Station is a new simple-cycle combustion turbine (CT) generating facility north of Astoria, South Dakota. In April, 2018, OTP awarded Sargent & Lundy the contract to assist in complete detailed design, to provide procurement and project controls services, and to provide overall project technical support. The Astoria unit will consist of an MHPSA M501GAC CT and associated balance-of-plant (BOP) equipment.
Project Scope
The firm provided procurement, project controls, detailed design and technical support to:
- Advise and make recommendations to OTP on division of scope of supply and contracting strategies for entire project; develop technical specifications for technical services, engineered equipment, and installation contracts; set performance guarantees, delivery milestones, and submittal requirements; serve as single point of contact to support OTP in resolving commercial inquires; and evaluate bids and issue letters of recommendation.
- Develop and maintain master project schedule through detailed design phase; provide input to project financial forecast; and issue monthly engineering reports with performance indices and schedule updates.
- Develop design criteria for major engineering disciplines; establish standards for drawings, files, and naming conventions to be used for unit’s future operations and maintenance.
- Attend meetings as necessary at supplier’s offices or factories; respond to requests for information during the commissioning and construction phase; conduct site visits during construction during critical activities; and review performance test results.
