1. A semi-submersible offshore platform comprises a main structure comprising two longitudinal lower side beam structures, two transverse lower side beam structures and four columns, the longitudinal and transverse lower side beam structures are located between the four columns connecting the four columns with each other such that the semi-submersible offshore platform exhibits a frame shaped submersible pontoon having a lower central opening, the four columns extends upwards from the frame shaped submersible pontoon,
wherein the main structure of the semi-submersible offshore platform comprises two longitudinal upper side beam structures and two transverse upper side beam structures, the longitudinal and transverse upper side beam structures are located between the four columns connecting the four columns with each other such that the semi-submersible offshore platform exhibits a frame shaped deck box structure having an upper central opening arranged to receive at least one structural module, where the structural module has a substantially rectangular shape, and comprises at least a first and second load carrying protruding element, the first load carrying protruding element is located on a first module side and the second load carrying protruding element is located on a second module side, the at least two load carrying protruding elements are arranged at a distance from a bottom of the structural module such that the structural module can hang in the upper central opening of the semi-submersible offshore platform, being carried by the at least two load carrying protruding elements such that air is allowed to flow through the upper central opening enabling an improved ventilation of the entire semi-submersible offshore platform. |
