Abstract

Claims (42)

1. A system for servicing watercrafts, comprising:

a controller;

one or more waterborne platforms including a first waterborne platform, the first waterborne platform comprising:

an electric power supply,

a driving system configured to move the first waterborne platform in a body of water,

a watercraft interfacing system comprising a recharging port configured to supply electric power to one or more electrically-powered watercrafts, and a control interface configured to exchange data with the controller;

wherein the controller is configured to:

receive input data; determine a respective target location for each of the one or more waterborne platforms to supply electric power to the one or more electrically-powered watercrafts, comprising applying the input data to an objective function of an optimization process associated with the respective target locations, the objective function including a first component specifying an energy required for the one or more electrically-powered watercrafts to each complete a respective navigation task conditioned on the one or more waterborne platforms being located at the respective target locations, and a second component specifying (i) an energy harvesting efficiency for the one or more waterborne platforms to harvest renewable energy at the respective target locations or (ii) an incentive for the one or more electrically-powered watercrafts to avoid a region for protected marine species;

send control data that includes data specifying the respective target location to each of the one or more waterborne platforms; and

wherein the driving system of first waterborne platform is configured to move the first waterborne platform based on the control data.

2. The system of claim 1 , wherein the electrical power supply includes a renewable energy source.

3. The system of claim 2 , wherein the driving system is powered at least in part by the renewable energy source.

4. The system of claim 2 , wherein the renewable energy source includes one or more of wind turbines.

5. The system of claim 4 , wherein the first waterborne platform further comprises a conversion system configured to reconfigure the wind turbine between a first mode and a second mode, wherein the wind turbine is configured to convert wind power to electric power when operating in the first mode, and configured to function as a wind sail to propel the first waterborne platform when operating in the second mode.

6. The system of claim 1 , wherein the recharging port is configured on a retractable boom, and the first waterborne platform is configured to, in response to receiving control data including a command to recharge a nearby watercraft:

move to a predetermined distance from the nearby watercraft;

extend the retractable boom from the first waterborne platform to cause the recharging port to connect with a connection port of the nearby watercraft to recharge a battery of the nearby watercraft; and

when the recharging is completed, withdraw the retractable boom to disconnect the recharging port from the connection port of the nearby watercraft, wherein:

during recharging, the first waterborne platform is configured to maintain a distance with the nearby watercraft by controlling the driving system based on real-time measurement of the distance between the first waterborne platform and the nearby watercraft.

7. The system of claim 1 , wherein the watercraft interfacing system further comprises a battery exchange system configured to exchange batteries with the one or more electrically-powered watercrafts.

8. The system of claim 1 , wherein the system comprises a plurality of waterborne platforms including the first waterborne platform, and the controller is configured to determine respective target location for each of the plurality of waterborne platforms, and send respective control data to each of the plurality of waterborne platforms.

9. The system of claim 8 , wherein the respective target locations for the plurality of waterborne platforms are arranged along one or more shipping routes in the body of water.

10. The system of claim 1 , wherein the objective function further includes a third component specifying a total cost for the one of more electrically-powered watercrafts to complete their respective navigation tasks conditioned on the one or more waterborne platforms being located at the respective target locations.

11. A waterborne platform for servicing electrically-powered watercrafts, comprising:

a controller;

an electric power supply,

a driving system for moving the waterborne platform in a body of water,

a watercraft interfacing system comprising a recharging port configured to supply electric power to one or more electrically-powered watercrafts, and

wherein the controller is configured to:

receive input data;

determine a target location for the waterborne platform to supply electric power to the one or more electrically-powered watercrafts, comprising applying the input data to an objective function of an optimization process associated with the target location, the objective function including a first component specifying an energy required for the one or more electrically-powered watercrafts to each complete a respective navigation task conditioned on the one or more waterborne platforms being located at the respective target location, and a second component specifying (i) an energy harvesting efficiency for the waterborne platform to harvest renewable energy at the target location or (ii) an incentive for the one or more electrically-powered watercrafts to avoid a region for protected marine species; and

wherein the driving system is configured to move the first waterborne platform to the target location.

12. The platform of claim 11 , wherein the electrical power supply includes a renewable energy source.

13. The platform of claim 12 , wherein the driving system is powered at least in part by the renewable energy source.

14. The platform of claim 12 , wherein the renewable energy source includes one or more of wind turbines.

15. The platform of claim 14 , further comprising a conversion system configured to reconfigure the wind turbine between a first mode and a second mode, wherein the wind turbine is configured to convert wind power to electric power when operating in the first mode, and configured to function as a wind sail to propel the first waterborne platform when operating in the second mode.

16. The platform of claim 11 , wherein the recharging port is configured on a retractable boom, and the waterborne platform is configured to, in response to receiving control data including a command to recharge a nearby watercraft:

move to a predetermined distance from the nearby watercraft;

extend the retractable boom from the waterborne platform to cause the recharging port to connect with a connection port of the nearby watercraft to recharge a battery of the nearby watercraft; and

when the recharging is completed, withdraw the retractable boom to disconnect the recharging port from the connection port of the nearby watercraft, wherein:

during recharging, the waterborne platform is configured to maintain a distance with the nearby watercraft by controlling the driving system based on real-time measurement of the distance between the waterborne platform and the nearby watercraft.

17. The platform of claim 11 , wherein the watercraft interfacing system further comprises a battery exchange system configured to exchange batteries with the one or more electrically-powered watercrafts.
