Wave-induced motions must be accounted for when calibrating sensor systems and designing controllers for offshore operations. During numerous offshore operations vessel-mounted cranes are expected to launch and land equipment either on fixed installations, on the seabed or on another vessel. The Motion Laboratory will advance the level of technology within this field, and will be at the research front within motion compensation.
The laboratory has two platforms with six degrees of freedom, which are also called hexapods or Stewart platforms. In addition, an industrial robot with an open control system is mounted on top of the largest hexapod. The platforms can simulate the wave-induced motions of vessels and floating constructions in a laboratory environment with extensive possibilities for measurement and registration. The Motion Lab serves as a cost-effective alternative to wave tanks and in field tests.
Wave-induced motions must be accounted for when calibrating sensor systems and designing control systems for offshore operations. A Motion Laboratory with platforms that simulate wave induced motions is a very valuable and cost efficient tool for doing research in this field.
The existing equipment at UiA consists of two Stewart platforms (hexapods) from Bosch-Rexroth. The equipment can handle large payloads (up to 8 tonnes) as well as vessel-to-vessel experiments. The laboratory also consists of additional cranes and robots for development of concepts for motion compensation.
To improve the existing Motion Laboratory new instrumentation and a transportable Stewart platform that can also be used outdoor/offshore and at research partners sites are applied for.
The upgraded Motion Laboratory will advance the level of technology within this field, and will be in the research front within motion compensation both nationally and internationally.
