  • Publication number: 20220065128
    Abstract: A stator aerodynamic component is disclosed to be placed inside a flow path of a working fluid of a turbomachine; the component has one or more nozzles for ejecting a liquid into the flow path; the liquid to be ejected comes from a duct internal to the component and in fluid communication with a pipe that is external to the component. Also disclosed is a method for cleaning a turbomachine by ejecting a washing liquid from one or more one stator aerodynamic components.

  • Patent number: 10724442
    Abstract: An aeroderivative gas turbine including an air intake plenum; a compressor with a compressor air intake in fluid communication with the air intake plenum; a combustor; a high pressure turbine; a power turbine. A forced air-stream generator is arranged in fluid communication with the air intake plenum. A shutter arrangement is provided in a combustion-air flow path, arranged and controlled to close the combustion-air flow path for pressurizing said air intake plenum by means of the forced air-stream generator to a pressure sufficient to cause pressurized air to flow through the aeroderivative air turbine.

  • Patent number: 10487973
    Abstract: A mounting system for supporting rotary machinery on a supporting structure of an off-shore installation, the system including a base frame provided with an upper side, for mounting the rotary machinery and a lower side, a set of at least four supporting members arranged at the lower side of the base frame and adapted to be placed on the supporting structure to act as an intermediate layer or frame between the base frame and the supporting structure in mounting condition. The supporting members include resilient elements generating a reaction force when subject to load and are configured to transfer to the base frame stresses and/or strains lower than allowable limits also in case of deformation of the supporting structures; the base frame has stiffness such as to guarantee design acceptance criteria for example for rotary machinery alignment, terminal points or interface point displacement, dynamic behavior or like parameters.

  • Publication number: 20150033756
    Abstract: A gas turbine including: a turbine package, a gas turbine, a ventilation system for cooling the interior of the turbine package, and a lubricating oil circuit. The lubricating oil circuit comprises a lubricating oil pump, a lubricating oil tank, a primary lubricating oil cooler, and a secondary lubricating oil cooler. The secondary lubricating oil cooler is arranged in the turbine package, in a position lower than a rotary shaft of the gas turbine. The ventilation system is arranged and designed such that at least part of a package cooling airflow contacts the secondary lubricating oil cooler to remove heat from the lubricating oil circulating in the secondary lubricating oil cooler.
