The platform includes 3 columns having upper ends projecting above water surface. The columns are canted or inclined inward from the corner of hull toward the central vertical axis. The 3 columns converge at the top of column such that each column will lean against the other 2 columns. Each column has two connection points to the other 2 columns. Horizontally disposed pontoons interconnect adjacent columns at the lower ends. The columns and pontoons form a closed structure hull to support a foundation structure directly above the top of column. ## Claims ### Claim 1 A floating platform, comprising: a. at least 3 columns (23), wherein each of said at least 3 columns comprises an upper end and a lower end; b. at least 3 pontoons (24), wherein each of said at least 3 pontoons comprises a left end and a right end; wherein, each of said at least 3 columns is connected to two adjacent columns of said at least 3 columns at said upper end to converge and form a surface for supporting of a topside, each of said at least 3 pontoons is horizontally disposed with said left end and right end separately connected to the lower ends of two adjacent columns of said at least 3 columns to form a closed hull structure whereby one or more of said at least 3 columns are canted or inclined inward. ### Claim 2 (depends on 1) The floating platform of claim 1, wherein one or more of said at least 3 columns or 3 pontoons have a cross section that is substantially rectangular. ### Claim 3 (depends on 1) The floating platform of claim 1, wherein one or more of said at least 3 pontoons is circular in shape. ### Claim 4 (depends on 1) The floating platform of claim 1, wherein one or more of said at least 3 columns is circular in shape. ### Claim 5 (depends on 1) The floating platform of claim 1, wherein said floating platform further comprises vertical tensioned lines. ### Claim 6 (depends on 1) The floating platform of claim 1, wherein one or more of said at least 3 columns are tapered columns (33) having a large sectional area at said lower end, and a small sectional area at said upper end. ### Claim 7 (depends on 1) The floating platform of claim 1, further comprising a double wheel fairlead (29). ### Claim 8 (depends on 1) The floating platform of claim 1, wherein one or more of said at least 3 columns comprises a vertical portion (13) and a canted portion (23). ### Claim 9 (depends on 1) The floating platform of claim 1, wherein said floating platform comprises 3 columns. ### Claim 10 (depends on 1) The floating platform of claim 1, wherein said floating platform comprises 4 columns. ### Claim 11 (depends on 1) A method of installing said floating platform of claim 1, comprising the steps of: a. providing a mooring system comprising mooring lines and connection devices; b. installing one of said connection devices on each of said at least 3 columns except for a last column; c. mooring all said columns installed with connection device in step (b) with said mooring lines one by one; and d. installing a line tensioning device on said last column and tensioning up all of said mooring lines to a desired tension. ### Claim 12 (depends on 11) The method of claim 11, wherein said floating platform comprises 3 columns.
