The present invention relates to an offshore
oil production platform. The platform includes a
deck (12) and a sub-structure (10) comprising plurality of
ballast chambers (20) and at least one of connecting leg (16) connected from the
ballast chambers (20) to the
deck (12). The
ballast chambers (20) include at least one
oil storage compartment (22), at least one ballast compartment (24) and at least one air pressure compartment (26). The oil and gas storage compartment (22) is for storing processed oil and gas. During installation of the platform, the ballast chambers (20) are ballasted with sea water (46) which allows lowering of the connecting legs (16) towards the sea
bed (34). After the ballast chambers (20) reach the sea
bed (34), locking means is actuated to a locked position to prevent movement of the sub-structure (10) of the platform. The
deck (12) is moved up to a predetermined height from
sea level by jacking means. After the oil is extracted, it is then processed and separated to processed oil and gas. The processed oil and gas are then stored in the oil and gas storage compartment (22). The oil and gas are then transferred to a
buoy and then loaded to tanker vessels by connecting conduits. During the de-installation of the
oil production platform, the ballast chambers (20) are de-ballasted whereby the sea water (46) in the ballast compartment (24) is flushed out. Thus, the sub-structure (10) of the platform moves upwards to reach the deck (12). When the base (14) touches the deck (12), the locking means is actuated thereby locking the sub-structure (10) together with the deck (12). Finally, the
oil production platform is towed to its new destination for further extraction of oil.
