## Abstract

An apparatus for use in marine platform jacking is disclosed herein. In one aspect, a jetting valve includes a valve body with a piston assembly disposed therein. The piston assembly is selectively operated to open and close the valve. A biasing member is coupled to the piston assembly. The piston assembly includes a first piston and a second piston. The dual pistons, in cooperation with the biasing member, allow the valve to self-seal thereby preventing entry of a fluid which is external to the valve.

## Claims

### Claim 1

A jetting valve, comprising:
a valve body;
a piston assembly disposed within the body, the piston assembly comprising:
a first piston;
a second piston; and
a shaft coupled to the first piston and the second piston; and
an insert coupled to the valve body having a portion of the shaft therethrough, wherein the insert and the first piston define a first volume and a second volume within the valve body, and wherein the insert comprises a plurality of flow apertures therethrough, the first volume and the second volume in fluid communication through the flow apertures.

### Claim 2 (depends on 1)

The jetting valve of claim 1, further comprising a spring coupled to the shaft and the insert.

### Claim 3 (depends on 1)

The jetting valve of claim 1, further comprising:
a cap; and
a port disposed within the cap, wherein the second piston is disposed within the port, the second piston selectively allowing fluid communication between the second volume and the port.

### Claim 4 (depends on 1)

The jetting valve of claim 1, wherein the first piston selectively allows access to, and blocks access to, the plurality of flow apertures.

### Claim 5 (depends on 3)

The jetting valve of claim 3, wherein a seal is disposed between the valve body and the cap.

### Claim 6 (depends on 3)

The jetting valve of claim 3, further comprising a shaft guide disposed between the cap and the insert.

### Claim 7

A valve cartridge, comprising:
an end piece having a port therethrough;
a housing member coupled to the end piece, wherein the housing member further comprises flow apertures disposed between a first surface and a second surface of the housing member;
a first piston disposed in the port;
a second piston disposed adjacent the housing member, wherein the second piston selectively allows access to, and blocks access to, the flow apertures; and
a shaft coupled to the first piston and the second piston.

### Claim 8 (depends on 7)

The valve cartridge of claim 7, further comprising a biasing member coupled to the shaft.

### Claim 9 (depends on 8)

The valve cartridge of claim 8, wherein the biasing member comprises a spring.

### Claim 10 (depends on 7)

The valve cartridge of claim 7, further comprising a shaft guide disposed around the shaft.

### Claim 11

A jetting valve system, comprising:
a pressure source; and
a valve coupled to the pressure source, the valve comprising:
a body having a first end and a second end, the first end in fluid communication with the pressure source;
an insert disposed within the body, wherein the insert comprises flow apertures disposed between a first surface and a second surface of the insert;
a shaft disposed in the body through the insert;
a first piston disposed adjacent the insert; and
a second piston disposed in a port in the second end of the body,
wherein the first piston and the second piston are coupled to the shaft.

### Claim 12 (depends on 11)

The jetting valve system of claim 11, wherein the second end of the body comprises a cap.

### Claim 13 (depends on 11)

The jetting valve system of claim 11, further comprising a biasing member coupled to the shaft.

### Claim 14 (depends on 11)

The jetting valve system of claim 11, wherein the first piston is selectively disposed against the second surface to allow access to, and block access to, the flow apertures.

### Claim 15 (depends on 11)

The jetting valve system of claim 11, further comprising a shaft guide disposed adjacent to the shaft.

### Claim 16 (depends on 11)

The jetting valve system of claim 11, wherein the pressure source provides a pressurized fluid to selectively operate the valve.

### Claim 17

A jetting valve, comprising:
a valve body;
a piston assembly disposed within the body, the piston assembly comprising:
a first piston;
a second piston; and
a shaft coupled to the first piston and the second piston;
an insert coupled to the valve body having a portion of the shaft therethrough, wherein the insert and the first piston define a first volume and a second volume within the valve body;
a cap; and
a port disposed within the cap, wherein the second piston is disposed within the port, the second piston selectively allowing fluid communication between the second volume and the port.

### Claim 18 (depends on 17)

The jetting valve of claim 17, wherein a seal is disposed between the valve body and the cap.

### Claim 19 (depends on 17)

The jetting valve of claim 17, further comprising a shaft guide disposed between the cap and the insert.

### Claim 20

A jetting valve system, comprising:
a pressure source; and
a valve coupled to the pressure source, the valve comprising:
a body having a first end and a second end, the first end in fluid communication with the pressure source, and wherein the second end of the body comprises a cap;
an insert disposed within the body;
a shaft disposed in the body through the insert;
a first piston disposed adjacent the insert; and
a second piston disposed in a port in the second end of the body, wherein the first piston and the second piston are coupled to the shaft.
