## Abstract

A sock for a floating platform including a plurality of tubulars coupled together and defining a bore and a catcher assembly. The catcher assembly including a plurality of orifices formed in at least one of the plurality of tubulars, a catcher releasably coupled to the plurality of tubulars by a plurality of shearable members, wherein the catcher is disposed in the bore, and wherein the catcher is movable from a first position to a second position, and a stop flange having at least one aperture.

## Claims

### Claim 1

A sock for a floating platform, comprising:
a first portion including a plurality of first tubulars coupled together; and
a second portion connected to the lower end of the first portion, wherein the second portion comprises a catching assembly having:
a second tubular;
a plurality of orifices formed in the second tubular;
a catcher releasably coupled to the second tubular by a plurality of shearable members, wherein the catcher is disposed in a bore defined by the plurality of first tubulars and second tubular, and wherein the catcher is movable from a first position to a second position; and
a stop flange having at least one aperture.

### Claim 2 (depends on 1)

The sock of claim 1, wherein each orifice of the plurality of orifices is about 0.5 inches to about 3 inches in diameter.

### Claim 3 (depends on 1)

The sock of claim 1, wherein the at least one aperture is a plurality of apertures.

### Claim 4 (depends on 1)

The sock of claim 1, wherein the at least one aperture is about 2 inches to about 5 inches in diameter.

### Claim 5 (depends on 1)

The sock of claim 1, wherein the stop flange is a first flange fastenable to a second flange, wherein the second flange includes the at least one aperture.

### Claim 6 (depends on 1)

The sock of claim 1, wherein the catcher includes a plurality of blind bores, wherein a respective shearable member is partially disposed in a respective blind bore.

### Claim 7 (depends on 1)

The sock of claim 1, wherein the plurality of shearable members are partially disposed between a first flange connected to the first tubular of the plurality of tubulars and a second flange connected to the second tubular, wherein a spacer is disposed between the first flange and the second flange.

### Claim 8 (depends on 1)

The sock of claim 1, wherein at least one of the tubulars includes a first support structure configured to be engaged with a second support structure of a cart configured to support the weight of the sock.

### Claim 9

A method of using a sock on a floating platform, comprising:
disposing a sock having a catcher, a stop flange having an aperture, and a plurality of orifices at least partially in a body of water, wherein the catcher is maintained in a first position by a plurality of shearable members;
releasing the catcher from the first position by shearing the plurality of shearable members in response to an impact of a dropped joint with a portion of the catcher;
displacing a column of water from a bore of the sock through at least one of the plurality of orifices and the aperture in response to the catcher descending in the bore;
engaging the catcher with the stop flange.

### Claim 10 (depends on 9)

The method of claim 9, further comprising:
after engaging the catcher with the stop flange, lifting the sock out of the body of water.

### Claim 11 (depends on 10)

The method of claim 10, further comprising:
after removing the sock out of the body of water:
removing a portion of the stop flange; and
removing the catcher from the bore of the sock.

### Claim 12 (depends on 11)

The method of claim 11, further comprising:
reattaching the catcher to the sock with a new plurality of shearable fasteners.

### Claim 13 (depends on 12)

The method of claim 12, further comprising:
disposing the sock with the reattached catcher at least partially in the body of water.

### Claim 14 (depends on 9)

The method of claim 9, wherein disposing the sock at least partially in the body of water induces supporting the sock from a cart.

### Claim 15 (depends on 14)

The method of claim 14, wherein the cart is a blowout preventer cart.

### Claim 16

A sock for a core storage, comprising:
a first portion including one or more tubulars; and
a second portion including:
a first tubular having an unobstructed bore configured to receive a coring tool, a upper end, and a lower end, wherein the upper end is open and the lower end is closed, and wherein the unobstructed bore extends from the upper end to the lower end;
a coupling connected to the upper end configured to couple the second portion to the first portion;
at least one sealing member configured to seal the coupling between the first portion and the second portion; and
a valve coupled to the lower end, the valve configured to selectively allow fluid communication with an interior of the first tubular.

### Claim 17 (depends on 16)

The sock of claim 16, wherein the first portion includes a support structure configured to be engaged with a second support structure of a cart.

### Claim 18 (depends on 16)

The sock of claim 16, wherein the lower end is closed by a base plate.

### Claim 19 (depends on 18)

The sock of claim 18, wherein the valve is disposed in the base plate.

### Claim 20 (depends on 16)

The sock of claim 16, wherein the at least one sealing member is a gasket.
