## Abstract

A safety off-shore drilling, pumping and storage platform for oilwells is provided wherein the structure has a first funnel like structure which floats near the ocean floor connnected by a long tube to a second floating funnel platform which floats on the surface of the water.

## Claims

### Claim 1

A safety off-shore drilling, pumping and storage platform comprising in combination:
a. a surface floating platform comprising a catchment basin in the form of a first inverted funnel having flotation means thereon and flexible means for anchoring said platform to the ocean floor,
b. a second catchment basin being in the form of an inverted submerged funnel, said basin having flotation means thereon and flexible anchoring means for attaching said funnel to the ocean floor, and
c. a flexible lightweight tube connecting said lower funnel to said upper funnel.

### Claim 2 (depends on 1)

The structure of claim 1 wherein the light weight tube is formed in a plurality of sections with clamping means for attaching the sections together.

### Claim 3 (depends on 1)

The structure of claim 1 wherein said tube is split vertically into sections of varying means to clamp the vertical sections together.

### Claim 4 (depends on 1)

The structure of claim 1 wherein the first catchment basin is displaced horizontally from the second catchment basin.
