1.0 SCOPE OF WORK

The scope of work covered by this instruction describes the basic mechanical field erection procedures required for the installation of the gas turbine unit and related system equipment.

This instruction is not intended to cover the installation details for every listed summary sheet equipment and/or use of the standard and special tools for gas turbine maintenance purposes as defined by MLxxx MLs F066 and 0104. This instruction provides the installation details for the specific gas turbine system equipment only with descriptions on the use of only those special tools required for erection purposes. All other equipment erection instructions are provided within the specific system erection instruction. The descriptions and instructions on use of gas turbine maintenance tools are provided in the Operation and Maintenance manuals.

2.0 DESIGN AND ERECTION PHILOSOPHY

2.1 System Description

The MS 91FA is a single shaft heavy duty 50 Hz (3000 RPM) The gas turbine is shipped as assembled unit, the GT’s withtheir integral base structures. The load couplings, Exhaust ducts, Inlet systems, on-base piping, combustion hardware and other related components are shipped as separate MLs for assembly at site.

2.2 Erection Philosophy and Sequence

2.2.1 Erection Philosophy

The gas turbine unit will be the first equipment to be set relative to the generator unit in line with the power train centerline.

Following the setting and positioning of the gas turbine on the foundation sub sole plates/fixators the exhaust diffuser (ML706) must be installed prior to performing any of the internal alignment checks. The generator an an entire assembly is lowered over it foundation bolts to its supports. The supports can either be soleplates or fixators. Again the unit position is adjusted into line with the power train centerline. All other gas turbine and generator components such as the load coupling, combustion system hardware, on-base piping, collector house and turning gear shall now be assembled prior to final alignment.

6.7 Equipment Painting

The gas turbine base and other related components are factory painted with one coat inorganic zinc, Carboline CZ11, followed by an epoxy top coat. Scuff marks, scratches and other damage to the primer or finish coat incurred during transportation to site and on-site handling or welding will require touch-up primer painting only. A final coat of paint is not required for the gas turbine, base and related components. All enclosures, inlet plenum, duct and filter house have been factory coated with exterior primer coat. Refer to GE drawing 357B9917 when selecting a suitable top coat paint.

6.5.1 Complete touch up painting per Instruction P6C-AG25 as found in Tab D of this instruction. Verify that all scratches and damage to exposed painted surfaces have been repaired.

6.8 Construction Conformity File

6.6.1 As a prerequisite to the system Commissioning activities and following erection of all gas turbine system components, through erection activity 6.3.1 to 6.6.11 a complete system installation inspection must be performed to verify any outstanding work. Complete final installation inspection and record any punch list MLs.

6.6.2 Verify that all Installation inspections sheets and other construction quality documentation has been completed in accordance with the project plan and filed in the Construction Conformity File.
