Abstract: A marine oil storage installation includes at least one floating type oil storage tank having a double bottom and double walls and is provided with shore connection means. Protector means composed of at least one line of floating members surrounds each oil storage tank for protecting each oil storage tank from damage as the result of waves and contacting moving objects and for preventing oil from flowing out. Mooring means for drawing each oil storage tank and, loading arm means carried on the mooring means adapted for connection and disconnection with the shore connection means on each tank are also provided. A shore based facility is installed on the shore or on an artificial land and communicates with the loading arm means, and a platform is installed in the sea for moorage of tankers and is provided with means communicating with the shore based facility for feeding oil between the tankers and the shore based facility.

Abstract: This invention relates to a safety submarine spherical air chamber made of a flexible material wherein persons are able to observe the undersea condition and the seabed from the scientific or recreational point of view by maintaining the atmospheric pressure of the above spherically expanded chamber approximately equivalent to the sea water pressure therearound, and then by floating therein a floating base on which they can stay.

Abstract: For mooring a vessel such as oil tanker, especially in deep water, a support located below the water contains a vertically slidable mooring post which can be lifted by an attached mooring hawser into engagement with a reception chamber formed in the bottom of the vessel. The support may rest on the sea bed in such a way as to be universally swingable but its upper end is restrained by anchor chains. The support cam take the form of an oil reservoir and the mooring post can be a tube through which the oil is transferred to the tanker. The hauling in of the mooring hawser through the reception chamber positions the vessel over the mooring post and the head of the latter is engaged by a resilient gripping ring which can act as an oil seal.

Abstract: A vertically-elongate monolithic pier body comprises:A deeply-submerged compartmented closed container or container group;A near-surface control chamber system;A deckwork carried above highest wave level;A load-carrying column and wall system extending in part through the container and chamber system, including a pair of perforated flanking walls; andA transverse wall and beam bracing framework extending in part through the container and chamber system, including a top wall and a thick slab base.The pier is intended to stand on seabed in depths of 450 feet to 1200 feet or deeper, to carry petroleum well-drilling and production equipment. The large container group is submerged at a depth where it is subjected to reduced wave pressures. The flanking pair of walls dissipate the energy of incident waves.Fabrication begins in a drydock site with the pier laid out horizontally extended.

Abstract: A cylindrical tank-like submarine hull acts as a cargo carrier and carries its propulsion element which is power driven through a power supply from a surface vessel through a power transport member interconnecting the surface vessel to the underwater carrier. The member interconnecting the surface vessel and the underwater carrier also carries the control line for steering and submerging of the underwater carrier actuated from the surface vessel.
