GAS TURBINE OFFSHORE INSTALLATIONS

摘要

The off-shore gas turbine system comprises a floating structure with at least one deck (25) and a baseplate (31) mounted on the deck. The baseplate supports a gas turbine (1) having: a low pressure compressor, a high pressure compressor, a combustor, a high pressure turbine, an intermediate pressure turbine and a low pressure turbine. The low pressure compressor is driven into rotation by the intermediate pressure turbine and the high pressure compressor is driven by the high pressure turbine. The low pressure turbine has a load coupling. The system further comprises a driven equipment (57, 59) mechanically connected to the load coupling (21) of the low pressure turbine and driven into rotation by the low pressure turbine. An intercooler (19) is provided between the low pressure compressor and the high pressure compressor and connected to them through displacement-tolerant connections. The baseplate (31) is supported on the deck (25) separately from the intercooler (19).
