A vertical flexible oil flow director hose is used to recover, to guide, and to filter the spilled oil from its source beneath the sea floor to the surface of water and to accumulate the floating oil therein for being ready to be pumped into an oil tanker. The said hose extends in the sea all the way from the sea floor to the surface of water by connecting its lower end to a circular sinking weight block and its upper end to a hollow doughnut-shaped floating device. The said hose includes two main portions abutting each other, the lower portion is for guiding and displacing water out through the gaps or meshes. The upper portion is for continued guiding and accumulating the oil in its upper section. A gas-tight dome cap having an opening at its bottom may be used to cap the upper opening of the oil accumulator well in the floating object, for holding the gas as necessary. A gas-compressor and gas tank or tanks will be equipped on the oil tanker ready to take and to store the gas.

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.

In certain offshore locations, for example off the West Coast of Africa, FPSO facilities provide an offloading facility to receive and load produced crude oil onto shuttle tankers. In such arrangements FPSO facilities use spread moored tankers with flowlines suspended in the water column to an offloading buoy or buoys which are located 1,000 to 1,500 meters away from the FPSO. Typically steel pipe flowlines as used with intermediate floatation to provide a suitable configuration that will avoid detrimental loads being imposed resulting from relative motions of the FPSO and the offloading buoy. According to the invention, a Suspended Pipe Line End Manifold (SPLEM) is connected to the end of the flowline assembly for support during towout. The SPLEM is positioned near the buoy and then connected at the sea surface to the bottom of the buoy by flexible leads such as anchor chains. The SPLEM is then flooded by selectively flooding compartments to cause it to sink to an operational position below the buoy. Next, additional submarine hoses or flexible pipe are connected to complete the flowline to the buoy.
