SGT-700 Industrial Gas Turbine Mechanical Mechanical Drive: (ISO) 32.04 MW (42,966bhp)
The Siemens SGT-700 industrial gas turbine is a high-performance gas turbine with excellent environmental compatibility. compatibility. It combines the reliability and robustness of an industrial design with the high efficiency and low emission levels of the latest turbine technology. technology.
The SGT-700 is an industrial gas turbine or mechanical drive applications. It is designed or heavy-duty operation under tough conditions, both onshore and oshore, loating or ixed, in hot or cold climates.
transients, variations in uel composition and ambient conditions. It also oers stability and DLE perormance or uels with high inert gas content and heavy hydrocarbons.
The SGT-700 is derived rom the well proven SGT-600. Together Together these turbines have more than six million operating hours and ield experience rom dierent operating conditions incorporated in the design.
The compact modularized design, small ootprint and low weight are o particular beneit in oshore applications. The standard electrical equipment design has been ully adapted or Ex-proo installation in hazardous areas and to meet oshore codes and standards.
The DLE (Dry Low Emissions) combustion combustion system is robust and simple with very high availability and no need or requent tuning. The DLE system is stable over the whole operating range including load
A single-lit module or loating platorms such as FPSO (Floating Production, Storage and Oloading) and semisubmersibles is available or both the SGT-600 and the SGT-700.
