Subsea power source, methods, and systems
First Claim
1. A subsea power source comprising:
- a housing comprising at least one first magnetic member;
an internal member comprising at least one second magnetic member; and
at least one elastic member positioned at an end of the housing,wherein at least one of the housing and the internal member is movable relative to the other of the housing and the internal member,wherein relative movement between said at least one first magnetic member and said at least one second magnetic member produces an electromagnetic output for powering a subsea object,wherein the internal member, the housing, or combinations thereof, is in fluid communication with a subsea environment,wherein movement of fluid within the subsea environment imparts a force to said at least one of the housing and the internal member thereby causing movement of said at least one of the housing and the internal member relative to the other of the housing and the internal member, andwherein contact between the internal member and said at least one elastic member causes said at least one elastic member to impart a force to the internal member thereby causing movement of said at least one of the housing and the internal member relative to the other of the housing and the internal member.

Abstract
Subsea power sources and related systems include a housing having at least one first magnetic member, an internal member having at least one second magnetic member, and at least one elastic member positioned in the housing. Movement of the one or more second magnetic members relative to the one or more first magnetic members, which can be obtained by positioning the power source in a subsea environment such that forces therein contact and move the housing or internal member, produces an electromagnetic output for powering a subsea object. Contact between the internal member and one or more elastic members causes the one or more elastic members to impart a force to the internal member to facilitate continued movement and power generation. Power generated in this manner or through other means is usable to operate a subsea kill plant, usable to kill a well or operate a subsea blowout preventer.

11. A method for generating power in a subsea environment, the method comprising the steps of:
-
providing into the subsea environment an apparatus comprising a first member having at least one first magnet and a second member having at least one second magnet; imparting a force to at least one of the first member and the second member by moving fluid within the subsea environment to contact said at least one of the first member and the second member to impart the force thereto, thereby causing movement of said at least one of the first member and the second member relative to the other of the first member and the second member, wherein the relative movement between said at least one first magnet and said at least one second magnet produces an electromagnetic output; contacting at least one elastic member with the second member, wherein contact between the second member and said at least one elastic member causes said at least one elastic member to impart a force to the second member thereby causing movement of said at least one of the first member and the second member relative to the other of the first member and the second member; and - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A system for killing a subsea well, the system comprising:
-
a subsea power source for producing an electrical output; at least one subsea motor in communication with the subsea power source for receiving power therefrom; at least one subsea pump in communication with said at least one subsea motor; a subsea accumulator in communication with said at least one subsea motor, said at least one subsea pump, or combinations thereof; and a blowout preventer in communication with said at least one subsea motor, said at least one subsea pump, or combinations thereof, wherein the subsea power source provides the blowout preventer with a continuous ability to close to prevent flow of fluid from the subsea well, and wherein the subsea power provides the subsea accumulator with a continuous ability to provide a kill weight fluid into the subsea well to prevent flow of fluid therefrom. - View Dependent Claims (19, 20, 21)

34. A subsea system for killing a well having a blowout preventer associated therewith, the system comprising:
-
at least one first accumulator in communication with the blowout preventer, wherein said at least one first accumulator is disposed on a subsea floor; at least one second accumulator in communication with the well, wherein said at least one second accumulator is disposed on the subsea floor; and at least one access point accessible to a remotely operated vehicle, a subsea power source, a surface conduit, a subsea conduit, or combinations thereof, wherein said at least one access point is in communication with said at least one first accumulator, said at least one second accumulator, or combinations thereof for providing power to said at least one first accumulator, said at least one second accumulator, or combinations thereof. - View Dependent Claims (35, 36)
