VMAX Technologies, Inc.

.: Jumper Installation

In this scenario the objective is to install a 6 inch Jumper on top of a PLET and Manifold. A Cameron Vertical Connector (CVC) running tool will be placed on each end of the jumper for installation. The ROV is used to help guide the CVC over the hubs for connection. Once the CVC tools are in place, a hotstab and torque tool will be used to release the CVC tool and install the Jumper between the hubs on the Manifold and PLET.

Look in the VMX folder to find a VMAX player file with a trainee completing the scenario.

.: Introduction

At the start of the scenario, there will be a cable suspended from the ship. Attached to this cable is the Jumper Assembly. This assembly consists of a straight spreader bar, the ends of the spreader bars have a daisy chain of cables which lead to CVC running tools. In between the CVC running tools is the straight 6 inch Jumper. This Jumper is to be installed on one end to a Pipeline End Terminal (PLET) and on the other end to a Manifold (Ref A)

.: Procedure

A normal operation to install a Jumper would usually involve two (2) ROV’s working in tandem, however for this scenario we will instead simulate an ROV working with the given trainees ROV. There are two sides of the Jumper, one side we call CVCA and the other CVCB. CVCA will be the side with the CVC tool that starts over the Manifold, while CVCB starts over the PLET (Ref A). You will notice on the Instructor View that two overlay items remain under the VMAX Logo (Ref B) These items are to help determine if you currently simulating an ROV holding either CVCA or CVCB side. The Simulation of the ROV acts as though the ROV is holding a side steady while the currently piloted ROV maneuvers the jumper over the designated hubs on the Manifold or PLET. It is very important to make sure both of the overlay items are set to false when the final removal of the CVC tools is initiated.

The following will allow for installation of the Jumper:
1. Using the Instructor GUI, choose the Control Tab. Choose the VMAX-Jumper Cable and pay the cable out by clicking on the Down button. (Ref C)
2. Pilot the ROV Towards the nearest CVC tool (CVCB).
3. Lower the cable until the CVC tools are near their connection points on the PLET and Manifold. (Ref D)
4. If necessary, toggle the “SimulateROV-CVCA” button. This will steady CVCA while you move CVCB to a correct position.
5. When CVCB is in the correct position, continue to pay out the VMAX-Jumper Cable.
6. If necessary, follow this procedure to install CVCA correctly. This may require you to toggle the “SimulateROV-CVCB” button.
7. Once both CVC tools are installed on top of their respective hubs, you can begin locking them in place. (Ref E)
8. Pilot the ROV to a panel on any side of the closest CVC tool.
9. Using the Rigmaster, grab the railing on the side of the panel.
10. Using the T4 manipulator, grab the Hotstab. This hotstab will be placed inside the given receptacle in the panel (Ref F).
11. Once the hotstab is installed, latch it into place. Now hit the CVC Softland button and then the CVC Actuator button to lower the CVC tool parts into position.. (Ref G)
12. Pilot the ROV as to be in a position to install the torque tool into the torque receptacle. (Ref H)
13. Once the torque tool is installed, latch it into place.
14. Then Activate the torque tool. This will unlock the CVC Tool and install the Jumper connection.
15. Unlatch the hotstab and take it out of its receptacle.
16. Repeat steps 8-15 for the other CVC tool.
17. Once both ends of the Jumper are installed, go back to the Instructor GUI and Pay in the VMAX-Jumper Cable.
18. Once both CVC tools are removed the Jumper will be fully installed (Ref I)

.: Notes to remember

· Use care when using the 7-Function Manipulator (T4) when grabbing the hotstab or torque tool. Large movements can cause the tools to penetrate objects.

· Ensure enough slack is given to the cables holding the CVC tools when they are installed on top of the hubs of the Manifold and PLET. This will allow for the CVC tool to operate correctly when moving down its Softland and Actuator components, otherwise the cable becomes unstable and starts shaking.

· The hotstab must be latched before you can activate the CVC Softland and Actuator components.

· When both CVC tools have been activated and the Jumper is installed, you will need to pay in the VMAX-Jumper Cable. While the CVC tools are being raised, ensure that they do not rotate in such a fashion as to hit the jumper. This will cause the CVC tool to collide with the jumper and the cables will become unstable. You will need to pay out the VMAX-Jumper cable and use the ROV to help guide the CVC tool away.
