GANGWAYS

GANGWAYS

Controllab has developed motion compensation controllers for a wide range of motion compensated gangways. The basis of our success is the digital twin, i.e a 3D simulation model, that we create for every access bridge. The digital twin enables us to develop and thoroughly test the software before the real bridge has been built. With this technology we have helped our customers to bring a new generation of highly advanced gangways on the market.

SYSTEM DYNAMICS

Every access bridge has performance limits like the maximum speed or maximum load. With system dynamics, we investigate these limits and see how they affect the design of the bridge. The basis is a parameterized 3D simulation model that we use to run simulations and investigate hundreds of scenario’s. Special techniques like time and frequency domain analysis are used to analyze the model and use the outcomes to make design improvements.

CONTROL SOFTWARE

Controllab has a set of of control system solutions that help to control a bridge in any environmental condition:

• Compensate for the motion of the ship in waves.

• Automatic landing control.

• Collision detection to prevent collisions of the bridge with the wind turbine platform.

DIGITAL TWIN

The coupling of a 3D simulation model with the control PLC’s is known as Hardware-in-the-Loop (HIL) simulation. With HIL simulation, the complete crane control system can be tested, before the bridge is actually built. This technique has been proven time and time again to increase the quality of the control system and reduce the number working days during the FAT and SAT. At Controllab we even go further. By extending the HIL simulator with a high-res 3D visualization, a digital twin emerges that can be used for training bridge operators.
