Abstract

Various aspects provide for “parking” an apparatus in a parking configuration. A parking configuration may be a configuration of an apparatus that minimizes damage (e.g., corrosion, wear, and the like) resulting from extended exposure during periods of inactivity. An apparatus may comprise a propulsion system (e.g., for a ship) and/or a steering system. An apparatus may comprise a linkage or other device positioned by an actuator. Some aspects include a water jet based propulsion system having a scoop and a nozzle operable to redirect the water jet, providing a range of forward/backward and port/starboard thrusts.

Claims (83)

1. A system for parking an apparatus during a period of inactivity, the system comprising:

an actuator having a working range and configured to be coupled to the apparatus to position the apparatus in a configuration within a range of motion of the apparatus, and

a platform comprising a computer readable non-transitory storage media coupled to a processor and a communication interface, the platform configured to:

receive an instruction to park the apparatus from the command console;

identify a parking configuration for the apparatus in which it is desirable to position the apparatus during the period of inactivity, wherein the parking configuration has a frequency of usage less than a predetermined frequency, the frequency of usage determined from a historical record of at least one of:

a frequency of configurations in the range of motion of the apparatus, and

a frequency of lengths in the working range of the actuator, and

instruct the actuator to move to a length in its working range that positions the apparatus in the parking configuration during the period of inactivity.

2. The system of claim 1 , wherein the actuator includes an electrical drive screw configured to be operated in a marine environment.

3. The system of claim 1 , wherein instruct includes instruct the actuator to move to a position that is within 10% of an end of the working range.

4. The system of claim 1 , wherein instruct includes instruct the actuator includes moving the actuator to a length that is at least 2 mm from an end of the working range.

5. The system of claim 1 , wherein the platform is further configured to:

receive sensor data from a sensor sensing an environment associated with at least one of the actuator and the apparatus; and

modify the parking configuration according to the sensor data.

6. The system of claim 1 , wherein the platform is further configured to:

receive time data from a time sensor that measures time, and

modify the parking configuration after a period of time.

7. A propulsion system comprising:

a water jet configured to generate a jet of water;

at least one of:

a scoop configured to controllably redirect the jet of water, and

a nozzle configured to controllably redirect the jet of water; and

the system of claim 1 , wherein the parking configuration for the apparatus comprises a propulsion parking configuration of the at least one of the scoop and nozzle, and wherein:

the actuator is coupled to the at least one of the scoop and nozzle, and

the platform is configured to park the at least one of the scoop and nozzle in the propulsion parking configuration.

8. The propulsion system of claim 7 , wherein:

the scoop is actuated by two scoop control cylinders; and

the nozzle is actuated by one nozzle control cylinder.

9. A system for parking an apparatus during a period of inactivity, the system comprising:

an actuator having a working range and configured to be coupled to the apparatus to position the apparatus in a configuration within a range of motion of the apparatus, and

a platform comprising a computer readable non-transitory storage media coupled to a processor and a communication interface, the platform configured to:

receive an instruction to park the apparatus from the command console;

identify a parking configuration for the apparatus in which it is desirable to position the apparatus during the period of inactivity, wherein the parking configuration is determined using data from a benchmark apparatus that is a different apparatus than the apparatus to which the actuator is configured to be coupled, and

instruct the actuator to move to a length in its working range that positions the apparatus in the parking configuration during the period of inactivity.

10. The system of claim 9 , wherein the platform is further configured to send an instruction to declutch or depower a propulsion system configured to communicate with the platform.

11. The system of claim 9 , wherein the platform is further configured to:

receive sensor data from a sensor sensing an environment associated with at least one of the actuator and the apparatus; and

modify the parking configuration according to the sensor data, and

wherein the sensor data includes configuration information identifying a configuration of the apparatus, and the platform is further configured to send configuration data that identify whether or not the apparatus has been successfully parked in the parking configuration.

12. The system of claim 9 , wherein the actuator includes an electrical drive screw configured to be operated in a marine environment.

13. The system of claim 9 , wherein instruct includes instruct the actuator to move to a position that is within 1% of an end of its working range.

14. The system of claim 9 , wherein the platform is further configured to:

receive sensor data from a sensor sensing an environment associated with at least one of the actuator and the apparatus; and

modify the parking configuration according to the sensor data.

15. The system of claim 9 , wherein the platform is further configured to:

receive time data from a time sensor that measures time, and

modify the parking configuration after a period of time that is at least one day.

16. A propulsion system comprising:

the actuator is coupled to the at least one of the scoop and nozzle, and

the platform is configured to park the at least one of the scoop and nozzle in the propulsion parking configuration.

17. The propulsion system of claim 16 , wherein:

the scoop is actuated by two scoop control cylinders; and

the nozzle is actuated by one nozzle control cylinder.

18. A system for parking an apparatus during a period of inactivity, the system comprising:

an actuator having a working range and configured to be coupled to the apparatus to position the apparatus in a configuration within a range of motion of the apparatus, and

a platform comprising a computer readable non-transitory storage media coupled to a processor and a communication interface, the platform configured to:

receive an instruction to park the apparatus from the command console;

identify a parking configuration for the apparatus in which it is desirable to position the apparatus during the period of inactivity, the parking configuration comprising a plurality of localized positions among which the apparatus moves, and

instruct the actuator to move to a length in its working range that positions the apparatus in the parking configuration during the period of inactivity.
