Currently, the platform is undergoing equipment modernization of its engineering systems, one stage of it being replacement of the pumping units used for transferring refrigerant agent within the platform's equipment cooling system.
In accordance with customer's requirements, Kronstadt specialists chose equipment most suitable for the project - three centrifugal pumps of NSL series by DESMI, a Danish company.
DESMI products are well-renowned among Russian factories. They have proved effective in both marine and oil development industries and deserved recognition at factories with high reliability requirements, where equipment replacement or repair is quite complicated due to remoteness of the sites.
The vertical centrifugal pumps DESMI NSL model 100-415/А02 supplied to the Korchagin platform fully comply with those requirements. Equipped with 90kW motors, the pumps demonstrate the flow of up to 220m3/h with the head of up to 61mwc. Pumps of this series are widely used in diesel motor cooling systems, as drainage or ballast pumps, for fire safety or transferring sea water purposes, in cold or hot water supply, in central heating systems, etc.
The Korchagin field is located in the Russian zone of the Caspian Sea bottom, 11 - 13 meters deep. Distance to the nearest shore (delta of the Volga) is about 120 km. The closest ports are in Astrakhan (175 km away) and Makhachkala (250 km away), railway stations - in Astrakhan, Makhachkala, Kizlyar, and in Derbent.
Kronstadt Engineering Company is to carry out all-in-one support of this supply. For the platform, our specialists will provide equipment installation and commissioning services.
