AMENDED CLAIMS

received by the International Bureau on 13 June 2014 (13.06.14)

1. A submersible power supply apparatus comprising:

a reserve battery module;

a modular reserve battery magazine having a compartment that houses the reserve battery module;

a reserve battery disposed in the reserve battery module; and

an electrically powered control system for controlling the power supply apparatus, wherein

the reserve battery module is configured to provide power under the condition that the reserve battery provided therein is activated by the electrically powered control system.

2. The submersible power supply apparatus according to claim 1, wherein the modular reserve battery magazine includes a plurality of compartments that house a plurality of reserve battery modules, and

a plurality of reserve batteries each disposed in a corresponding one of the plurality of reserve battery modules.

3. (Canceled)

4. The submersible power supply apparatus according to claim 1, further comprising:

a communication unit that communicates when at least one reserve battery module of the plurality of reserve battery modules is activated.

5. The submersible power supply apparatus according to claim 4, wherein the communication unit is configured to communicate with an external control unit to remotely control the electrically powered control system.

6. The submersible power supply apparatus according to claim 4, wherein the communication unit is configured to communicate an electrical performance of an activated reserve battery module of the plurality of reserve battery modules. 2

7. The submersible power supply apparatus according to claim 4, wherein the electrically powered control system activates a predetermined number of reserve battery modules depending on an amount of power required.

8. The submersible power supply apparatus according to claim 1, wherein the power supply apparatus is provided as part of a subsea system, wherein the subsea system includes at least one of manned vehicles, unmanned underwater vehicles, distributed energy storage, and point-of-load energy storage.

9. The submersible power supply apparatus according to claim 1, wherein the reserve battery in the reserve battery modules is selected from a group including lithium alloy/iron disulfide thermal batteries, molten salt high temperature thermal batteries, silver zinc batteries, and lithium/oxyhalide batteries.

10. The submersible power supply apparatus according to claim 1, wherein the reserve battery module includes an electrical activation.

11. The submersible power supply apparatus according to claim 1, wherein the reserve battery module includes a mechanical activation.

12. The submersible power supply apparatus according to claim 1, further comprising a reserve battery which is a primary battery, wherein the primary battery may be either activated or inactivated.

13. The submersible power supply apparatus according to claim 1 , further comprising:

a rechargeable battery, wherein the rechargeable battery is charged utilizing power generated from alternative energy and/or power plants.

14. The submersible power supply apparatus according to claim 1 , wherein the power supply apparatus is provided in a system that is at least one of a point of load electrical power distribution, a hybrid power system, and a critical system.

15. The submersible power supply apparatus according to claim 1 , wherein the power supply apparatus is provided in a subsea system that is disposed on a seafloor.
