Abstract (en)
[origin: WO0200496A1] A floating platform for offshore drilling or production of hydrocarbons comprises a topsides with drilling and/or production equipment (8), and a substructure comprising a lower pontoon (3) and columns (4) connecting the pontoon (3) to the topsides (1). During its operation the platform is exposed to wave forces (9) which cause heave motion (v) and roll and pitch motion (p) of the platform. The substructure has a draught (11) which is at least 40 metres, preferably at least 50 metres and most preferred at least 60 metres, and the ratio between the distance (16) between the columns' centre axes (25), measured along a side of the substructure, and the lower substructure's draught (11) is between 1.0 and 1.5, preferably between 1.2 and 1.4 and most preferred between 1.3 and 1.35.
