Abstract

A sub-surface sensor housing for remote underwater vehicle deployment and recovery. Moreover, a housing for a sub-surface sensor, comprising a housing body, having a top side, a bottom side, and a sensor cavity in which a sub-surface sensor is placed, wherein the housing body further comprises a plurality of slots through its walls slightly larger than a clamp tie; an attachment hoop coupled to the top side of the housing body, configured to receive a gripping hook from an aquatic vehicle, wherein the attachment hoop has a vertical height that extend above an interference zone; and a plurality of outriggers, coupled to the bottom side of the housing body, configured to disperse the weight of the housing the subsurface sensor.

Claims (30)

1 . A housing for a sub-surface sensor, comprising:

a housing body, having a top side, a bottom side, and a sensor cavity in which a sub-surface sensor is placed, wherein the housing body further comprises a plurality of slots through its walls dimensioned to permit passage of a flexible tie selected from a cable tie or a hose clamp band to secure the sensor with the sensor cavity;

a plurality of outriggers, coupled to the bottom side of the housing body, configured to disperse the weight of the housing the subsurface sensor each outrigger extending laterally at least about seven inches from the housing body; and

an attachment hoop coupled to the top side of the housing body, configured to receive a gripping hook from an aquatic vehicle, wherein the attachment hoop has a vertical height measured from the sea floor to a highest point of the hoop when the housing rests on the plurality of outriggers.

2 . The housing for a sub-surface sensor of claim 1 , wherein the housing body is a hollow cylinder having a diameter of about two to five inches and length of twenty-five to thirty-five inches.

3 . The housing for a sub-surface sensor of claim 1 , further comprising:

a cross bar, having a plurality of ends, mounted to the top side of the housing body for aligning the aquatic vehicle ROV with the attachment hoop and to provide a counterforce when the aquatic vehicle grips the attachment hoop.

4 . The housing for a sub-surface sensor of claim 3 , further comprising:

a plurality of tabs, each tab coupled to each of the plurality of the ends of the crossbar, configured to confine the housings lateral movement relative to the aquatic vehicle and to guide the aquatic vehicle during gripping.

5 . The housing for a sub-surface sensor of claim 1 , wherein the housing body further comprises a forward end that includes an opening exposing the; sensor cavity, and a sensor window at the forward end through the housing body.

6 . The housing for a sub-surface sensor of claim 1 , wherein the housing body further comprises a rear end, wherein a mounting bracket is coupled to the top side of the housing body at a location about four inches from the rear end of the housing body.

7 . The housing for a sub-surface sensor of claim 6 , wherein the mounting bracket is an “L”-channel.

8 . The housing for a sub-surface sensor of claim 1 , further comprising:

a float block coupled to the housing body, the float block providing a buoyant force to neutralize the weight of the housing.

9 . A sub-surface sensor housing for remote operated vehicle (ROV) deployment and recovery, comprising:

a housing body, having a top side, a bottom side, a forward end, and a rear end, for housing a sub-surface sensor, further comprising:

a plurality of slots through its walls sized to receive a cable tie or a hose-clamp band to secure the sensor within the sensor cavity,

a sensor window formed from the forward end of the housing body,

a mounting bracket coupled to the top side of the housing body;

an attachment hoop coupled to the top side of the housing body, configured to receive a gripping hook from an ROV and having a vertical height between about fourteen inches and about seventeen inches measured from the sea floor to a highest point of the hoop when the housing rests on a plurality of outriggers;

a cross bar mounted to the top side of the housing body for providing alignment when interfacing with the ROV's frame and to provide alignment and counterforce for accurate gripping; and

a plurality of outriggers, coupled to the bottom side of the housing body, configured to disperse the weight of the sub-surface sensor housing, each outrigger extending laterally at least about seven inches from the housing body.

10 . The housing for a sub-surface sensor of claim 9 , wherein the housing body is a hollow cylinder capable of encapsulating a cylindrical oceanographic current meter or current profiler sensor.

11 . The housing for a sub-surface sensor of claim 9 , further comprising:

a plurality of tabs, each coupled to each of the plurality of the ends of the crossbar, configured to confine the housings lateral movement relative to the ROV and to guide the ROV during gripping.

12 . The housing for a sub-surface sensor of claim 9 , wherein the sensor window spans about six inches along the length of the housing body.

13 . The housing for a sub-surface sensor of claim 9 , wherein the mounting bracket is about four inches from the rear end of the housing body.

14 . The housing for a sub-surface sensor of claim 13 , wherein the mounting bracket is an “L”-channel.

15 . The housing for a sub-surface sensor of claim 9 , further comprising:

a float block coupled to the housing body, the float block providing a buoyant force to neutralize the weight of the housing.
