18.4Mechanical Installation

18.4.1TPIM-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.

18.4.2Mounting

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.

18.4.3Alignment 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.

18.4.4Lube 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.

18.4.5Gas 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.

18.4.6Gas 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.

18.5Documentation

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.”

18.5.1Torsional 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.
