Abstract

A semisubmersible drilling platform has two longitudinal pontoons (1) from which columns (2, 3) extend upwards and support a deck (4). In order to provide a cheap production platform which may permit exploitation of marginal oil fields and concurrently provide alternative employment for such a drilling platform, it is provided with a supplementary unit (6) comprising storage tanks (7) for crude oil. The supplementary unit has an internal access tunnel (10) communicating with the deck (4) through an access shaft (11). The supplementary unit is built as an independent unit having sloptanks (8) and pump rooms (9). The supplementary unit (6) is attached to the pontoons (1) where these have bulkheads, by means of brackets (12). These brackets may simply be burnt through if the platform structure again is to be converted back to a drilling platform, or one may remove only the transverse portions of the supplementary unit and let the longitudinal portions remain in order to give the drilling platform increased carrying capacity.
