NOV Drilling Simulator Presented by Tore Berg
Company Overview National Oilwell Varco is a worldwide leader in the design, manufacture and sale of equipment and components used in oil and gas drilling and production, the provision of oilfield inspection and other services, and supply chain integration services to the upstream oil and gas industry. Our main buisness topic in Norway is design and producing of machines used for drilling on offshore vessels. We are also designing and producing cranes for the offshore and marine market. Revenue for NOV Norway in 2010 was 3,5 billion USD
Global Presence National Oilwell Varco have 41000 employees worldwide and 3000 employees in Norway. In Norway are we located in Kristiansand, Stavanger, Asker, Tønsberg, Molde, Arendal and Trondheim. The head office in Norway is located in Kristiansand.

Drilling HIL Simulator What is NOV Drilling HIL Simulator? The DHS is a drilling simulator that uses the original machine and HMI software to make the drilling operation into real life. It is designed so that it is possible to make fault and scenarios by manipulating with sensors and processes. The DHS can be used either for training or for testing of software before, while or after a rig have come in operation. All the models in the simulator is imported from the engineering tools.

Development of 3D models How do we develop 3D models for use in the simulator? NOV are using a 3D Cad software called Autodesk Inventor to do the mechanical design of the machines. The engineering models contain very detailed information. To be able to use this models in a real time simulator, we import them into 3D studio Max and reduce the complexity of the model. The reducing of the models are more or less done automatically. In 3D studio Max, we link the different assemblies, add textures, shadings and physics. To be able to move the model based on an input signal from the simulation controller we use a technic called key framing.
Development of 3D models When the models is ready in 3D studio we export them with use of Ofusion. This exporter will generate one file for the model and one for the Physics. The 3D engine we are using is Ogre (Object-Oriented Graphics Rendering Engine). This is a open source scene-oriented, flexible 3D engine written in C++. The Physics engine we are using is Nvidia Physx.
3D Code The code for the 3D engine is built up in a plugin structure. Some of the functions we have in the 3D engine as plugins are Waves Shadows Time of day (Sunlight) Down hole simulating Communications We use.xml files to enable the different plugins.
Development of Simulation code What tools are we using for making the simulation? NOV use different tools when developing simulation code. We use Math lab/simulink, Simulation X and PLC code. We generate Math lab/simulink into.dll files that we are running on IPC s. We can also combine this.dll with PLC code. In that way are we not so independent of who is making the simulation and what tool they are using for each model. The simulation code is built up with clear interface points. Because of this structure is it easy for other vendors to make their own simulation and integrate it into this simulator. Especially when using a independent supplier of the HIL test this is useful.
Development of Simulation code How do we develop a simulation? The sketch contains a electrical controlled valve and a cylinder with position and pressure feedback. This is a typical scenario that we are making simulation for. The next slide will show a signal flow chart for a simulation like this.

HIL Simulation What is the integrated HIL simulation in the DHS? HIL (Hardware in Loop) is a intergrated tool that is a standard for all DHS. This tool enables us to manipulate all sensors on the machines. Verify the software for the drilling machines and all integrated systems. For some machines/systems is it difficult to do this verification on the actual machine. This tool allows us to do the test in a safe way. We have developed some standard objects to do the sensor manipulating that is explained in the next slide.
HIL Simulation DI/DO object is used for HIL simulation of digital I/O. It is 3 functions in this object. Force High, Force Low and Invert. AI/AO object is used for HIL Simulation of analogue I/O. It is 5 functions in this object. Broken wire,freeze, Manipulate, Expert and Slider. The Expert object is used for extended HIL Simulation of this data type
