Description

The differences of GTU-10PC gas turbine from the GTU-10P base design (for GPA-C-6.3 retrofit) are determined by particular conditions of tie-in and location of components in the upgraded gas turbine pumping unit.

During retrofit the hardware from GTU-10PC is installed on the existing foundation into an existing enclosure with upgrading of gas pumping set systems.

The hardware provides for upgrading of gas compressor systems for the GTU-10PC installation, and also, replacement or upgrading of out-of-date or worn-out systems, and it is determined by the specification approved by the Customer.

Automatic control unit (ACU) is based on МSКU-SS 4510-10-38, and is common for gas turbine pumping sets and other gas turbine mechanical drive systems.

Advantages

The retrofit of GPA-C-6.3 gas turbine pumping unit with application of GTU-10PC gas turbine and new hardware allows to improve the performance, that is:

to improve reliability of the driven engine systems;
to improve reliability of the modified systems;
to reduce the consumption of fuel gas;
to reduce irretrievable losses of lube oil;
to improve the ecological characteristics.
The retrofit is carried out with maximum use of existing systems of the unit.
