Boilermakers weld temporary
attachments to heater shell in 4
locations over the cut line (If
required). Supports are designed to
allow the cutting head to travel
through the support.

The crane is released while Tri-Tool
installs the cutter and performs the
entire cut to the shell. The shell is
supported by the walls (temporary
supports if required) saving 72
hours of crane time through
removal and installation of the new
shell.
The Boilermakers rig the lifting
device to the crane. The lifting
device is then set on the heater
room walls and attached to the
new lugs previously welded to the
heater shell.
Tri-Tool removes cutting
equipment and the crane is re-
attached to the lifting device and
the heater shell.

Attachments are cut by torch at
the top of the attachment before
the heater shell is lifted out by the
crane. Bottom welds will be
removed by grinding after the lift.
The crane then lifts the old heater
shell out of the room to be set on
cribbing on the turbine deck or
truck bay.
