A few weeks after introducing 44 MW aeroderivative, Siemens a new aeroderivative gas turbine targeting the offshore oil and gas industry. The SGT-A35 RB, previously known as the Industrial RB211-GT30, is based on the Industrial RB211 and Industrial Trent 60 gas turbines. Siemens had acquired the technologies when it bought Rolls-Royce.
The SGT-A35 RB is a turbine derived from Rolls-Royce aerospace and marine Trent, as well as Siemens Industrial Trent 60. The new turbine, which can generate up to 38 MW, is integrated into a compact Dresser-Rand package that is 30% smaller and lighter than RB211. The construction of the package makes it suitable for offshore applications, such as floating production, storage and offloading (FPSO) vessels.
The SGT-A35 RB is available in 34 and 38 MW variants for various applications. Both the models are available for mechanical drive and power generation, 50 or 60 Hz. As a power generator. the gas turbine can directly drive the generator.
The gas turbine is also ideal in hot climates, boosting a thermal efficiency that exceeds 40% at ISO conditions. At 86°F (30°C), the gas turbine retains more than 90% of its ISO power output, says the OEM.
