RECEIVING AND STORAGE
3.6 RECEIVE TURBINE, GENERATOR, TURNING GEAR AND ALL OTHER GE
SUPPLIED EQUIPMENT
3.6.1 Receipt of Equipment and Materials
Inspect all incoming material for loss or damage. Inspection includes the
protective covering and packing for obvious damage, blocking of
components on delivery carrier for shifting during shipment.
Checking factory installed accelerometers (hump meters) where provided
(normally the turning gear, turbine base front and aft ends, and generator
base front and aft ends).
Other equipment that will be received includes; Accessory Module,
Atomizing Air/Liquid Fuel Module, PEECC Compartment, Batteries, BAC,
Water Injection Skid, Cooling Water Module, Fire Protection Skid, Liquid
Fuel Forwarding Skid, and Water Wash Skid.
Loss or damage should be reported in accordance with receiving policies,
procedures and regulations.
3.6.2 Storage Of Equipment And Materials
Equipment and/or materials are to be stored and/or preserved in
accordance with General Electric GEK-28156B Gas Turbine and
Accessory Equipment Preservation Instruction. Some equipment (e.g., gas
turbine-generator) may require temporary power for heating or drying either
prior to or once it is set on the foundation, depending on weather conditionsand the duration. Material should be arranged to accommodate efficient
installation.
3.7 RIGGING AND SETTING EQUIPMENT
Installer is responsible for all off-loading, on-site transportation, rigging, lifting and
setting of items outlined on Exhibit A.

weeks prior to the delivery of the major centerline equipment. This affords the Installer
sufficient time to prepare the sub-sole plates, shims and centerline guides (See Fig. 3).
Note: The preferred method of setting gas turbine and generator is to rig, pick-up
and set with a crane or gantry crane. Another method is to set the
equipment on skidding device and roll from the truck onto foundation.
3.9 GAS TURBINE
Set turbine down on hard wood blocking approximately 24 to 36 high over anchor
bolts. Jack turbine down over anchor bolts on sub-sole plates and shim packs. Adjust
shim packs to correct centerline elevation. Installer will provide all materials such as
anchor bolts, nuts, one inch (1) washers etc., and grout required for setting and
leveling. (See Fig. 4).
3.10 INSTALL LOAD COUPLING TO TURBINE (INLET END) (MLI 1319)
Installer is responsible for assembly and installation of the turbine load coupling. All
bolting is to be measured, assembled and torqued per specifications. The field has
found it easier to assemble the coupling to the turbine before setting the generator (See
Fig. 5).

is to be made up to the turbine and generator bases. The collector assembly
and turning gear shall also be free standing with no lube oil piping wiring or
conduit connected.
3.14.2 Final alignment readings will be taken in accordance with GE instructions.
Note: The Exhaust Diffuser (MLI 0706) must be assembled to the
turbine before final readings are taken.
3.14.3 Installer will final align generator to turbine, turning gear to generator, install
foundation centerline keying devices and make up couplings per GE
drawings. It is recommended that alignment readings be witnessed and
signed off by the Owner, Installer and General Electric. (See Fig. 9).
