Turbomachinery Package Specification Taurus 70 Compressor Set and Mechanical Drive
18.3 Site Requirements
Solar's gas turbine compressor sets and mechanical drive packages require minimal site
preparation. The package is supplied with self-contained systems for starting, fuel, lube
oil, and control, minimum piping and wiring connections are required for installation. All
service connections are conveniently located on the outer edge of the skid.
18.4 Mechanical Installation
18.4.1 TPIM-1010
Solar’s document TPIM-1010 “Package Installation Guideline – Compressor Sets and
Mechanical Drives” outlines the responsibilities of the Customer and Solar regarding
installation of the package. It provides guidelines for the installation of the standard
package design and the interface with the turbine driven equipment.
18.4.2 Mounting
Correct mounting of the gas turbine package is vital to successful package installation
and requires adequate preparation by the user. The site pad thickness is governed by
soil condition and the weight of the gas turbine package, air inlet system, and exhaust
system. Mounting pad locations and loads will differ with each package, depending upon
selected options, and will be clearly shown on the installation drawings. The equipment
layout should provide adequate floor space for major components with sufficient room
around the package for routine maintenance access.
18.4.3 Alignment Tooling
As an option, alignment tooling can be provided to align the turbine or gearbox output
shaft hub to the driven equipment input shaft hub. The alignment tooling includes a dial
indicator kit, alignment tool, axial distance gauge, and custom storage container.
18.4.4 Lube Oil Cooler(s)
The lube oil cooler(s) must be located off-skid. The interconnect piping is not part of
Solar’s standard scope.
18.4.5 Gas Turbine Air Inlet System
The gas turbine air inlet should be located so that entry of gas turbine exhaust, oil tank
vent vapor, or other contaminants is minimized. The air inlet duct must be free of
accumulated water prior to starting the gas turbine.
18.4.6 Gas Turbine Exhaust System
The importance of having an exhaust system properly installed cannot be
overemphasized. A poorly installed exhaust system can cause a loss of power and
impose severe mechanical strains on the gas turbine. The exhaust duct system must be
terminated in a manner that precludes recirculation of exhaust products through the gas
turbine air inlet or oil cooler. Exhaust installation considerations include the relative height
of the exhaust duct above the air inlet, building roof design, direction of prevailing winds,
and the proximity of adjacent structures. When exhaust silencing is required, provisions
must be made to adequately mount and support the equipment and limit the exhaust
silencer pressure loss.
18.5 Documentation
Solar provides extensive documentation for its Turbomachinery projects. This includes
electrical and mechanical drawings, quality control data books, and operation and
maintenance manuals. Details of this documentation and its delivery timetable are
