Hi3. ABSTRACT 
Large floating ocean platforms are envisioned as satisfying 
basing requirements of the Navy in the mid 80's. The floating plat- 
forms would consist of structural components mass-produced, con- 
tructed into modules ashore, launched, towed to the site and assemblef 
into platforms. 
This investigation studied various configurations using concrete 
as the construction material. The scope of effort included synthesis 
of concepts, concrete production, construction methodology and cost, 
and an RDT&E plan. It is concluded that concrete is a feasibile and 
practical construction material for large ocean platforms.
