Boilermakers weld lifting lugs to old shell. The lugs are designed to match the connection style of the new heater shell lugs.

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.

The lifting device is detached from the heater shell and carried to a staging location. The heater shell can then be rigged with nylon slings and laid horizontal in the Sea / Land.
