Drill Ship Inspection Mission
Drill Ship Inspection
Level of difficulty: 1
Overview: The ROV is launched from the side of a drill ship with rig deployed.
Goals: Safely operate the ROV from the surface to the ocean floor while locating and identifying all the major components of the rig, riser, BOP, etc. A forth camera is mounted on the wrist of the right, 7 DOF manipulator to assist your inspection.
Evaluation: Performance gauged by operator’s skill in ROV maneuvers and ability to locate and identify rig components. Press the keyboard’s “z” key to reveal labels for major rig components.
Pipeline Inspection Mission
Pipeline Inspection
Level of difficulty: 3
Overview: An oily sheen was reported in the vicinity and due to wind and current the exact location of its source is unknown. There are 4 pipelines in the immediate area. A forth camera is mounted on the wrist of the right, 7 DOF manipulator to assist your inspection.
Goals: Conduct an inspection of the pipelines in order to locate the source of the suspected leak. Find and record the leaks location (Latitude/Longitude), the number of the pipe and its date of installation.
Evaluation: Performance gauged by operator’s skill in ROV maneuvers, use of SONAR to navigate and ability to maintain umbilical using TMS. Each time the mission is run the location of the leak will be different. By pressing the keyboard’s “z” key a relative bearing and range to the leak will be displayed on the screen.
Lost AUV Search Mission
Lost AUV Search
Level of difficulty: 4
Overview: An Autonomous Underwater Vehicle (AUV) was lost in the vicinity while conducting survey operations. It’s exact location is unknown but is believed to be within 1 nm (2 km) of your current position. A forth camera is mounted on the wrist of the right, 7 DOF manipulator to assist your inspection.
Goals: Conduct a search pattern of the ocean floor to locate the lost AUV. Find and record the AUV’s location (Latitude/Longitude).
Evaluation: Performance gauged by the operator’s skill in ROV maneuvers, use of SONAR to navigate and locate the AUV, and the team’s ability to maintain the umbilical using the TMS. Each time the mission is run the location of the AUV will be different. By pressing the keyboard’s “z” key a relative bearing and range to the AUV will be displayed on the screen.
Mooring Anchor Inspection Mission
Mooring Anchor Inspection
Level of difficulty: 2
Overview: The captain in charge of mooring operations for a floating oil platform reports that he suspects on of the mooring anchors has not set properly. A forth camera is mounted on the wrist of the right, 7 DOF manipulator to assist your inspection.
Goals: Locate the mooring gear (rode and anchor) and record their condition, whether they are fouled or set properly. Also draw a map of any obstructions found that may interfere with setting an anchor in that vicinity and assist in locating a more suitable area if required.
Evaluation: Performance is gauged by the operator’s skill in ROV maneuvers, use of SONAR to navigate and locate the anchor, and the team’s ability to maintain the umbilical using the TMS.
Oil Platform Inspection Mission
Oil Platform Inspection
Level of difficulty: 3
Overview: A routine inspection of the oil platform is to be conducted. A “Cathodic Potential” (Cp) probe is mounted to the wrist of the right, 7 DOF manipulator and mini observation ROV are included to assist in your inspection. The Cp probe is activated by pressing the keyboard’s “z” key.
Goals: Record any visual damage or obstructions that are observed including their location. Conduct a thorough Cp survey of the horizontal frame and record any irregularities.
Evaluation: Performance is gauged by the operator’s skill in ROV maneuvers, ability to discern issues, and operation of manipulators and Cp probe. Team performance is judged by their ability to maintain positional awareness and maintain the umbilical using the TMS.
Suction Dredge Intervention Mission
Suction Dredge Intervention
Level of difficulty: 3
Overview: An oily sheen was reported in the area and its source located. In the vicinity are several oil pipelines, some of which have been covered by loose sand and silt. An inspection class ROV has been deployed and is prepositioned at the suspected leak.
Goals: A 5″ suction dredge is mounted to the wrist of your right 7-DOF manipulator that you will use to remove sand and silt to expose the source of the leak. The dredge is activated by pressing the keyboard’s “z” key.
Evaluation: Performance is gauged by the operator’s skill in ROV maneuvers and use of manipulators and suction dredge. Team performance is judged by their ability to maintain positional awareness and maintain the umbilical using the TMS.
Suction Pile Anchor Intervention Mission
Suction Pile Anchor Intervention
Level of difficulty: 5
Overview: Mooring operations for a platform is being conducted and a suction pile anchor has been lowered, installed and awaits confirmation that it is positioned properly, level and then valves closed and bridle released.
Goals: Locate the anchor and verify it is level by checking it’s bull’s eye level. Close the two main valves by turning their control levers clockwise. Locate each quick release shackle and release it by turning it’s lever counter clockwise.
Evaluation: Performance is gauged by the operator’s skill in ROV maneuvers, minimum thruster power is used to maintain position and minimum force is used to control valves and shackles. Team performance is judged by their ability to properly position ROV to accomplish each goal and maintain position while effecting each task. Team is further judged by their ability to maintain positional awareness and maintain the umbilical using the TMS.
