A method and three embodiments for continuously removing a film of pollutant, as oil, from floating on the water solely by gravity forces is disclosed. One apparatus comprises a closed top collecting vessel or tank of water elevated above the oil covered water with a large conduit extending from the bottom of the tank down into the oil, so that as the oil continuously and uninterruptedly floats up internally of the conduit and tank to the top of the tank, the water is simultaneously and continuously displaced and sinks down through the tank and conduit to the water below. With a plurality of tanks filled with water mounted not higher than 33 feet on a barge being pulled behind a barrier for gathering and banking up the oil just ahead of the barge, a floating pollutant or oil removal system is formed by extending conduits from the bottoms of the water tanks sloping downwardly over the barrier into the floating oil. After establishing a continuous exchange of the oil for the water in the tank by continuous gravity flow of both the oil and the water through the interconnecting conduit in opposite directions simultaneously, the conduit lower end may then be lowered slightly below the interface between the oil and the water, particularly when inadvertently lowered as the layer of oil becomes thin, for continued replacement of the water in the tank with the oil from below. As the oil rises continuously in the conduits and tanks to the top of the tanks, the water simultaneously and continuously sinks down to the water below to accordingly pick up only pollutants of lower density than water, as oil or oil emulsions to provide maximum oil concentration in the collecting vessel tank.

Mechanisms for joining two telescopic cylinders underwater in a temporary and inexpensive manner are disclosed, particularly when used in anchoring piles or in offshore tower legs. A gun fires projectiles radially from internally of the pile formed of telescopic cylinders to form the plurality of outwardly extending anchoring bumps in the walls of the cylinders. The projectiles are fired in a horizontal plane radially outwardly and from within and normal to the two telescopic cylinders underwater, for example, with two bumps being formed by each projectile, which bumps overlie each other tightly prior to their being penetrated by the projectile which holds the two bumps together. A number of radiating guns form a like number of pairs of bumps in a circle around the periphery of the telescopic cylinders to form an efficient, inexpensive, and simple temporary connection holding the two cylinders together. After forming the bumps in the buried pile cylinders and simultaneously packing the soil around them, each projectile penetrates its bump and packed soil to provide a pile or offshore tower legs with high resistance to separation of the telescoped cylinders forming the pile or offshore tower legs, with increased load-carrying-capacity and with increased resistance-to-pull-out.

Methods for joining two telescopic cylinders underwater and underground in a temporary and inexpensive manner are disclosed, particularly when used as anchoring piles or in offshore tower legs. A gun fires projectiles radially from internally of the pile formed of telescoped cylinders to form the plurality of outwardly extending anchoring bumps in the walls of the cylinders. The projectiles are fired in a horizontal plane immediately outwardly and from within and normal to two telescopic cylinders underwater, for example, with two bumps being formed by each projectile, which bumps overlie each other tightly prior to their being penetrated by the projectile which holds the two bumps together. A number of radiating guns form a like number of pairs of bumps in a circle around the periphery of the telescopic cylinders to form an efficient, inexpensive, and simple temporary connection holding the two cylinders together.

Three methods for forming three different, double acting, self-contained swages for joining two small diameter tubes are disclosed. Likewise three double acting small diameter (31/2 inch) combination hydraulic-mechanical swages assembled by the methods are disclosed using hinge arms with indentation tips thereon for deforming and connecting together two small (less than 7 inches or 18 centimeters diameter) telescopic tubes for casing repair or a flow line connection, for example. Two modifications formed by the methods have links connected to the swaging arms so that with increased pivotal movement of the arm and link, a gain results in the mechanical advantage and indentation force.

A method for fixedly positioned marine platform held at the ocean floor by piles and the like, having a relatively flat concrete apron disposed about the platform lower end and also supported on the ocean floor. The apron functions to stabilize the platform against lateral forces caused by water and wave motion, and also avoids scouring which would otherwise occur about the platform legs and piles due to movement of water along the ocean floor. The apron further lowers the center of gravity of the structure and improves its resistance to vibrations and resonance effects due to wave motion.

Likewise three double acting small diameter (31/2 inch) combination hydraulic-mechanical swages assembled by the methods are disclosed using hinge arms with indentation tips thereon for deforming and connecting together two small (less than 7 inches or 17. 78 centimeters diameter) telescopic tubes for casing repair or a flow line connection, for example. Two of the modifications have links connected to the swaging arms so that with increased pivotal movement of the arm and link, a gain results in the mechanical advantage and indentation force.

A method for making transparent an underwater work area covered with cloudy water for servicing an offshore well and a subsurface well servicing and life supporting work chamber for practicing the method comprising a submarine chamber rotatably mounted on a base positioned centrally of a group of wells around the periphery of the base is disclosed. The chamber has a water filter and an ejection nozzle for ejecting clear water from the filter into an underwater cloudy area over a well to be serviced for providing a relatively transparent area of clear water to see through and work in.
