OSC has spent the last 15 years developing some of the worlds most advanced simulation solutions for the offshore industry. The Software architecture, Graphics, Hardware and flexibility within the solutions is years ahead of our competition. All OSC solutions are based on one common core software platform. Within this we have spent years developing a virtual world with all parameters based on real world details, therefore adding content is very fast and behaves with real physics. Basing all core products on the same software platform gives incredible versatility and opportunity for the fast development virtual prototyping. This puts OSC in a unique position of being able to use the same simulators for training and verification of complex, custom operations, as users know that the behavior experienced in the simulator is exactly as will be seen in the real offshore operation.
Physics and collision
OSC physics run analysis in real time, based on the assigned materials’ properties of the objects, weight and COG. This ensures that collisions respond correctly, including friction coefficient between objects.
All permutations of a flexible coupling (wire, chain, hose, rope etc.) resolution is dynamically altered to ensure optimal simulator performance, while maintaining accuracy. In practice, this means that long stretches of anchor chain, for example, have a high segment length as they are not colliding with other objects or being flexed, whereas wire lying on deck has a short segment length to ensure accurate behavior.
Physical parameters, such as winch speed and response are set in the simulator to ensure that the behavior is as in reality. Alternatively, for extremely specific simulation, customers can apply their own Functional Mock-up Units (FMUs) for simulated systems such as hydraulics. This has the added benefit of the customer protecting their IP while having an extremely accurate simulation. OSC standard co-simulation time step is 20Hz.
Training possibilities
Simulators are designed specifically to provide training in best practices and to test and build the level competence required to carry out even the most critical operations. It provides training for different operations, including human factor interaction and load planning exercise.
Virtual prototyping
OSC have created a simulation world which has all the real-world environment factors to be used onshore or offshore and even in solutions with interaction between surface and subsea/subsurface.
OSC has built up a wide knowledge of simulating environmental forces, such as wind and waves, through over ten years of working with offshore crews accustomed to the most challenging environments on the planet. This knowledge is applied in the environment OSC provides as standard in all simulation.
The instructor station can control and change parameters for wind shielding, atmospheric pressure, geo location and time of day and year, wave aware, wind waves, water current shielding, lee effect, ocean transparency.
Augment tools:
Tools for augmenting simulation, add another dimension to project solutions and training.
The ocean can be hidden in real-time simulation, giving a perfect view of the subsea environment and or lifting object in a subsea lift. The environmental effects (wind, waves, current etc.) motions of vessels, movement of lift objects are all still live and calculated real-time, only with full visibility below the water surface.
OSC Sandbox:
A new tool that enable customers to build complex simulation scenarios by drag and drop 3D models into Sandbox. Simulation for verification can then be run and the risks of a solution, or operation, can be found within minutes.
Examples of functions:
-
Placement of load objects and rotation of objects
-
Change weight and CoG
-
Insert loose objects (shackles, tools etc.)
-
Vessel-/Rig layout
-
Training scenario creation
Building with primitives in Sandbox:
-
For fast prototyping it can be very effective to build directly in the simulator using primitive shapes. These can be scaled to the sizes required, locked together to create more complex objects, the weight of these, and center of gravity, can be changed.
