Abstract

A subsea fluid distributor comprises a support framework removably mountable and hydraulically connectable to a subsea structure intermediate the subsea structure and an incoming flying lead's terminator; a plate attached to an upper section of the support framework; a fixed bucket and a valve attached to the support framework; a lower framework attached to a lower portion of the support framework; a first hydraulic tube, in fluid communication with the valve, attached to the lower framework; a flying lead junction plate support framework attached to the lower portion of the support framework; a second hydraulic tube, in fluid communication with various subsea equipment, disposed at least partially within the flying lead junction plate support framework; a first remotely operated vehicle (ROV) torque bucket attached to an upper portion of the flying lead junction plate support framework; and a second ROV torque bucket attached to the upper section of the support framework.

First claim

We claim:

1. A subsea fluid distributor, comprising:
a. a support framework configured to be removably mounted to a subsea structure intermediate the subsea structure and an incoming flying lead terminator of an incoming flying lead;
b. a plate attached to an upper section of the support framework;
c. a fixed bucket attached to the support framework;
d. a valve attached to the support framework;
e. a lower framework attached to a lower portion of the support framework;
f. a first hydraulic tube attached to the lower framework, the first hydraulic tube in fluid communication with the valve;
g. a flying lead junction plate support framework attached to the lower portion of the support framework;
h. a second hydraulic tube disposed at least partially within flying lead junction plate support framework, the second hydraulic tube in fluid communication with a predetermined subsea equipment;
i. a first remotely operated vehicle (ROV) torque bucket attached to an upper portion of the flying lead junction plate support framework; and
j. a second ROV torque bucket attached to the upper section of the support framework.

2. The subsea fluid distributor of claim 1 , wherein the hydraulic tube comprises a plurality of hydraulic tubes.

3. The subsea fluid distributor of claim 1 , wherein the second hydraulic tube comprises a plurality of second hydraulic tubes.

4. The subsea fluid distributor of claim 1 , further comprising a flotation attachment junction attached to the upper section of the support framework.

5. The subsea fluid distributor of claim 1 , wherein the valve comprises a chemical injection metering valve or a chemical throttle valve.

6. The distribution structure of claim 1 , wherein the fluid distributor further comprises:
a. an incoming receptor; and
b. an outgoing channel distributor in fluid communication with the incoming receptor.

7. The subsea fluid distributor of claim 6 , wherein the incoming receptor comprises a hydraulic incoming receptor or a chemical incoming receptor.

8. The subsea fluid distributor of claim 1 , wherein the plate comprises a removable multi-quick connector (MQC) plate.

9. The subsea fluid distributor of claim 1 , further comprising a predetermined set of signal connectors attached to the upper section of the support framework.

10. A method of subsea fluid distribution for a subsea fluid distributor comprising a support framework configured to be removably mounted to a subsea structure intermediate the subsea structure and an incoming flying lead terminator of an incoming flying lead; a plate attached to an upper section of the support framework; a fixed bucket attached to the support framework; a valve attached to the support framework; a lower framework attached to a lower portion of the support framework; a first hydraulic tube attached to the lower framework, the first hydraulic tube in fluid communication with the valve; a flying lead junction plate support framework attached to the lower portion of the support framework; a second hydraulic tube disposed at least partially within flying lead junction plate support framework, the second hydraulic tube in fluid communication with a predetermined subsea equipment; a first remotely operated vehicle (ROV) torque bucket attached to an upper portion of the flying lead junction plate support framework; and a second ROV torque bucket attached to the upper section of the support framework the method comprising:
a. disposing the support framework intermediate a subsea structure and an incoming flying lead terminator of an incoming flying lead;
b. connecting an incoming flying lead to the incoming flying lead connector;
c. connecting an outgoing flying lead to the outgoing flying lead connector; and
d. providing a predetermined fluid through the distributor from the incoming flying lead to the outgoing flying lead.

11. The method of subsea fluid distribution for a subsea fluid distributor of claim 10 , further comprising daisy-chaining an outgoing flying lead from a first subsea fluid distributor to an incoming flying lead of a second subsea fluid distributor.

12. The method of subsea fluid distribution for a subsea fluid distributor of claim 10 , further comprising:
a. supplying the subsea fluid distributor with an integral chemical valve; and
b. passing a chemical through the integral chemical valve to perform a predetermined function.

13. The method of subsea fluid distribution for a subsea fluid distributor of claim 12 , further comprising using the integral chemical valve to supply fluid to a subsea equipment that does not have a chemical valve pre-installed on that subsea equipment.
