The disclosure provides an offshore platform (2) and related method, having: a floating structure (4, 6), a truss assembly (7) coupled to the floating structure, and a heave plate (28) coupled to the truss assembly. The floating structure includes a pontoon (6) adapted to be disposed at least partially below a surface of water in which the offshore platform (2) is disposed; and at least three vertically extending columns (4) coupled to the pontoon (6), the columns having a larger lateral dimension than the pontoon coupled to the column, creating a pontoon offset portion (24). The truss assembly (7) includes at least three separated walls of trusses (8) slidably coupled to the columns (4), each truss wall (8) having at least two vertically disposed truss legs (10), each truss leg (10) being slidably coupled to a column (4) at the pontoon offset portion (24) independently from a truss leg (10) of an adjacent wall; and cross -bracing (12) between the truss legs (10) of each of the truss walls (8). |
