A method of constructing a coil wound heat exchange module and transporting and installing the coil wound heat exchange module at a plant site, such as an natural gas liquefaction plant. A module frame is constructed and attached to a heat exchanger shell prior to telescoping of a coil wound mandrel into the shell. The module frame includes a lug and two saddles that remain attached to the shell throughout the process and when the heat exchanger is operated. The lug and saddles are constructed and located to stabilize the shell during construction, telescoping and transport (when in a horizontal orientation), and when the shell is installed at the plant site (in a vertical orientation). The lugs and saddles are adapted to allow for thermal expansion and contraction of the shell when it is transitioned from ambient to operating temperature and vice versa.
