1. A modular pipe rack system, comprising:
a set of self-supporting tower modules aligned along a fluid transport path, each tower module including:
(a) exactly four vertical columns, and
(b) four I-beams connected to the vertical columns by biaxial moment connection collars forming a first pipe support tier, wherein each of the biaxial moment connection collars connects exactly two I-beams to one of the four vertical columns;
a strut beam extending between first and second adjacent tower modules of the set, the strut beam being connected to one of the four vertical columns of each of the first and second tower modules by a shear connection.
