60 Compressor Set and Mechanical Drive
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) can be mounted on an ancillary support frame on top of the
enclosed package or located offskid.
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
contained in Solar’s Product Information Letter 184 “Order Fulfillment & Documentation
for Oil & Gas Projects.”
18.5.1 Torsional Analysis Report (Optional)
A torsional analysis can be performed on the entire drive train to determine if there are
any significant torsional resonance conditions within
±
10% of the operating speed range.
