Subsea power source, methods, and systems
First Claim
1. A system for killing a subsea well, the system comprising:
- a subsea power source operable for producing an electrical output, the subsea power source comprisinga 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 the at least one first magnetic member and the at least one second magnetic member produces an electromagnetic output, 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 the at least one of the housing and the internal member thereby causing movement of the at least one of the housing and the internal member relative to the other of the housing and the internal member, and wherein contact between the internal member and the at least one elastic member causes the at least one elastic member to impart a force to the internal member thereby causing movement of the at least one of the housing and the internal member relative to the other of the housing and the internal member;
at least one subsea motor in communication with the subsea power source for receiving power therefrom;
at least one subsea pump in communication with the at least one subsea motor;
a subsea accumulator in communication with the at least one subsea motor, the at least one subsea pump, or combinations thereof; and
a blowout preventer in communication with the at least one subsea motor, the at least one subsea pump, or combinations thereof,wherein the electromagnetic output from 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 electromagnetic output from the subsea power source provides the subsea accumulator with a continuous ability to provide a kill weight fluid into the subsea well to prevent flow of fluid therefrom.

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.

10. 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 the at least one first accumulator is disposed on a subsea floor; at least one second accumulator in communication with the well, wherein the at least one second accumulator is disposed on the subsea floor; at least one access point accessible to a remotely operated vehicle, the subsea power source, a surface conduit, a subsea conduit, or combinations thereof, wherein the at least one access point is in communication with the at least one first accumulator, the at least one second accumulator, or combinations thereof for providing power to the at least one first accumulator, the at least one second accumulator, or combinations thereof; and a subsea power source comprising a housing and an internal member, wherein the housing comprises at least one first magnetic member, wherein the internal member comprises at least one second magnetic member, wherein at least one of the housing and the internal member are movable relative to the other of the housing and the internal member, and wherein relative movement between the at least one first magnetic member and the at least one second magnetic member produces an electromagnetic output for powering the at least one first accumulator, the at least one second accumulator, the at least one access point, or combinations thereof. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
