Offshore
In the marine & offshore market a big driver for the automation of machines is the increased demand for safety and accuracy. These demands can be met by using digital twins. Controllab has been active in the offshore market for more than 20 years. With our digital twins we help companies to design and test control software and provide training simulators for cranes, gangways, cable lay and other complex machines. In the offshore lot of special equipment is being used for the oil and wind industry.
With our technology we can efficiently develop digital twins for special machines. We have build digital twins for a pile gripper, boat landing tool, boom lock, passenger transfer systems and more. The benefits for our digital twins allowed our customers to improve their quality, work faster, reduce stress and save cost. For more information about a specific issue, please feel free to reach out to us. Our dedicated Engineering team is readily available to assist you and find a solution to your problem.
Offshore Cranes
Controllab is specialized in the analysis and development of control software for cranes. The basis of our success is the digital twin, i.e a 3D simulation model, that we create for every crane. The twin enables us to develop and thoroughly test the software before the real crane has been built. With this technology we have helped our customers to develop highly successful new cranes.
Every crane 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 crane. The basis is a parameterized 3D simulation model that we use to run simulations and investigate hundreds of scenarios. Special techniques like time and frequency domain analysis are used to analyze the model and use the outcomes to make design improvements.
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.

Pipe and cable lay
The complexity of pipe and cable lay machinery is not only stems from the individual machines but also from the coordinated way of operation to lower a cable or pipe safely from the ship. Controllab has developed control systems for tensioners, straighteners, carousels and more. 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 pipe and cable lay machine has been built.
Monopile grippers
Monopile grippers are used to keep a monopile upright during hammering and prevent it from falling over. Traditionally this is done with Jack Up ships, but recently also DP crane vessels are being used. The monopile gripper on a crane ship has to compensate for the motion of the ship, making it a highly dynamical system.
The loads on a dynamic monopile gripper are quite large, which puts limits onto the power and the speed of the system. With system dynamics, we investigate these limits and see how they affect the design of the gripper. The basis is a parameterized 3D simulation model of the ship, the crane and the gripper. Environmental loads in the form of wind, waves, current and the soil conditions are added as well as the gripper control system. Controllab is one of the few companies who are able to couple all of these simulation models and run simulations to test the performance of the gripper.
