Multiple systems and methods for providing supervised control of subsea vehicles for offshore asset management as well as supplemental autonomous control behaviors are described herein. These systems and methods provide offshore support and alternative supervised control of one or more vehicle generally irrespective of where the vehicle resides in an oil and gas offshore field.

Methods for subsea vehicles supervised control

A resident remotely operated vehicle may be deployed subsea by deploying a remotely operated vehicle (ROV) () configured to be disposed and remain resident subsea for an extended time where the ROV comprises an ROV electrical power connector port () to be operatively connected to an electrical power supply () dedicated to the ROV. An RTMS configured to be disposed subsea for an extended time is also deployed subsea (), typically proximate the ROV. A subsea docking hub subsea is also deployed subsea proximate the RTMS and operatively connected to the ROV and the RTMS. In addition, an umbilical is connected from the subsea docking hub to a subsea structure and a signal supplied from the subsea structure to the ROV.

Autonomous ROVs with offshore power source that can return to recharge

A power management system comprises a remotely operated vehicle (ROV), a tether management system (TMS), and an umbilical operatively in communication with the TMS external electrical power interface and the TMS-to-ROV umbilical interface. The system can be configured to provide electrical power management that moves some or all of the electrical power required for ROV propulsion and tooling to the ROV and/or TMS, and maximizes available power and manages loads across all systems as necessary and by priority. Power management may also be required that features intelligent routing of power to subsystems and integration of variable frequency drives (VFDs).

Remotely operated vehicle power management system and method of use

A TMS, cage type or top hat type incorporates a deployment frame. The TMS may be operated by a winch from a surface vessel. The TMS delivers a main ROV and a smaller mini ROV. The main ROV is fully functional to accomplish the necessary task subsea. However, in the event there is an operational failure of the main ROV, the mini ROV can be deployed. The mini ROV may have fewer functionalities than the main ROV, but can at least offer video and lighting to allow monitoring of a particular location subsea. All the necessary positioning capabilities are available on the mini ROV.
