Title: CONTROL OF REMOTELY OPERATED VEHICLE'S DYNAMIC POSITIONING SYSTEM BY EXTERNAL NAVIGATION SYSTEM
Abstract:
Embodiments, including systems and methods, for remotely controlling underwater vehicles (such as ROVs) and deploying ocean bottom seismic nodes from the underwater vehicles. A direct data connection may be created between an Integrated Navigation System (located on a surface vessel) and a ROV controller / Dynamic Positioning (DP) system (which may be located on the surface vessel and/or the ROV). The INS may be configured to output the ROV target position and ROV position (such as standard 2 or 3 dimensional coordinates) to the DP system. The DP system may be configured to calculate the necessary ROV movements based on directly received data from the INS. Based on a selected ROV target destination or desired ROV action (which may be done automatically or by an operator), the ROV may be automatically positioned and/or controlled based on commands from the DP system based on commands and/or data from the INS.
