Udo Leist Email: [email protected] Always ready for the future! WENDT SIT More than 125 years have now passed since the foundation of the first WENDT company in April 1874 in Berlin and the name WENDT SIT keeps on going for a high customer satisfaction through quality and service. In 1960 WENDT group shifted their activities to Ludwigshafen and around the turn of the century to Frankenthal. From the classical supplier and manufacturer WENDT advanced to be a service industry on technical matters presenting complete solutions from project planning to final assembly. Highly motivated, flexible and experienced employees ensure a high quality standard documented by the certificates according to ISO EN DIN 9001 and the security management system (SCC). The worldwide WENDT SIT activities comprise deliveries/supplies of customized sound proofing systems, heat and low temperature insulations in terotechnology and the installation of power stations as well as high temperature insulations of various kinds in engine construction. Technical advice, specific solutions to problems, development of acoustic systems and silencers on which WENDT SIT has patents as well as individual engineering performances made us famous. The WENDT SIT products are manufactured in own workshops and mounted through qualified employees worldwide. The documentation drawn up for this purpose enables the customer even to selfmounting. The WENDT SIT reference list reveals the trust of international companies: Alstom Power; BMW; EVOBUS; GHH; LINDE; MAN; KSB; MWM; SIEMENS; KAWASAKI; AUDI; BASF; VW; HOECHST; Braden Europe BV; Daimler Chrysler; Freudenberg; KK&K; LURGI; MTU; Rheinbraun; VEBA; VBA; Shell; BP; Esso. On a surface of 18.000m² is WENDT SIT in the position to realize all the customer’s demandsboth subject-specifically and fit in to schedule by means of fully automatic production lines controlled electronically.

Leist [email protected] The acoustic enclosure is part of a power plant located in the kingdom of SaudiArabia in the counties of Asir & Bisha. Three units will be executed. Wendt SIT GmbH was ordered to deliver these acoustic enclosures with completely new design, which is expected to become an execution standard for future projects. The acoustic enclosure is designed for an outdoor arrangement with the benefit to replace the turbine building of the power plant. This manner leads to an enormous cost reduction and was one of the important arguments for the positive decision of the customer to this kind of execution. The shown acoustic enclosure has the function to reduce noise emissions caused by a gas turbine and its connected generator. The enclosure is divided into two different compartments, one for the gas turbine and one for the generator. Special operation conditions have to be considered during design period to meet the technical requirements of the project. The enclosed machinery has a big heat loss, so the acoustic enclosure has to be equipped with a ventilation system to fulfil maximum interior temperatures lower than 60°C. Higher temperature inside would be harmful for the electrical equipment and would also not allow access of maintenance personnel during operation. Special attention was paid to the hazardous area inside the gas turbine compartment, e.g. when there is a leakage in the turbo machinery system. The acoustic panels of the enclosure have the advantage to be removable without loosing any connection elements. The wall and roof elements are executed weatherand gas tight as well. On the roof top of the generator compartment a filter house building is located. The loads of this building are integrated into the design of the enclosure. The structural steel structure is also used to support the piping of the machinery. A lot of interfaces of components by others had to be considered during design period. Several penetrations caused by the generator bus duct, turbine diffuser, ventilation ductwork and piping are integrated into the design of the acoustic enclosure. Static System The static system of the acoustic enclosure is based on a frame. The static analysis acc. EC3 is calculated using a 3D-model to optimize the weight of the structural steel. The columns of the steel structure are aligned in a way that the front flanges of the column sections have the same outline dimensions to allow easily assembly of the wall elements. Therefore additional eccentricities had to be considered. The steel structure is designed for easy disassembly to allow fast access to the machines for maintenance and repair purposes. Wendt SIT GmbH delivered the following Software Acoustic design of the enclosure elements including splitters silencers of the ventilation system Complete design, layout -, outline-, detail- & erection drawings Static analysis of the steel structure and structural parts of the enclosure including the consideration of seismic & wind loads.
