Wartsila Corporation

Pipeline & Gas Journal, May, 2008

With global demand for natural gas rising and a 50% increase expected by 2030, Wartsila Corporation recently introduced its popular Wartsila 34SG gas engines to the gas compressor market. Having outputs of 4,050-9,000 kW, these gas engines are said to offer considerable lifecycle cost improvement for compressor owners and operators.

Typical applications are for gas pipelines and for gas storage. For a typical 9,000 kW compressor drive installation, owners with a Wartsila 34SG gas engine driver can expect to lower their lifecycle costs by around 20-40% compared with other prime movers on the market. The cost savings will be even bigger when compared with existing, older compressor drives, making upgrades an attractive prospect. The Wartsila 34SG engines are available in three variants: The 9-cylinder inline Wartsila 9L34SG with 4,050 kW shaft power, the 16-cylinder Wartsila 16V34SG engine of 7,200 kW, and the 20-cylinder Wartsila 20V34SG with 9,000 kW shaft power. The nominal speed is 750 rpm. www.wartsila.com.
