Chevron Gaviota Marine Terminal Gas Turbine Generator Package at Gaviota, California designed by MTSI. Custom engineered pulse clean air filter package with divided plenum for combustion and generator air. Generator compartment positively pressurized, Turbine Compartment negatively pressurized by redundant exhaust fans at left. Generator cooling air discharges from screened hood on top of main air cleaner package.
The Gaviota Marine Oil Terminal receives and processes wet crude oil and wet gas from offshore production platforms in the Santa Barbara Channel off the California coast. Large amounts of process steam are required for these operations.
MTSI assisted a Detroit Diesel Allison distributor in the procuring of the contract which required the design and supply of five (5) Allison 501KB gas fired, water injected generator sets each with a heat recovery boiler. This required a boiler with the reheat duct burner downstream of the first evaporator to raise the gas temperature entering a second evaporator stage in order to gain maximum steam production without excessive gas temperature, as would have been, required in a single evaporator boiler.
MTSI performed the detailed design of the gas turbine generator sets, the water injection system and gas turbine unit controls, and bus tie panel with station power factor controller. MTSI also manufactured all Gas Turbine Generator unit controls and the bus tie panel. An exhaustive factory emissions test was required for this unit with data being logged over the complete power range, with and without water injection, and burning natural gas fuel. MTSI's scope of work included the preparation of factory test plans to meet the requirements of the contract.
View showing heat recovery steam generators each rated 72,000 pph, 100 psig. Diverter valves and boiler outlets, are manifolded thru reheat duct burner, SCR, and secondary HRSG. Boilers contain two LP evaporator sections with duct burner between the two evaporators.
Gas Turbine Generator Control Panels with bus tie panel designed and manufactured by MTSI. Unit Control Panels included Woodward electronic fuel and water/fuel ratio controllers, Gould Programmable Logic Controllers and Bentley Nevada Vibration and Temperature Monitors.
