Automated stripe coat application to floating offshore foundations

Stripe coat application to weld seams, free edges, bolts and other difficult-to-coat areas is costly and labor-intensive. For large structures, the automation of this process is a promising innovative approach to accelerate coating processes and to reduce costs, materials and resources. 

The following issues were addressed in the OWSplus project: 

–    Integration of an electrostatic painting device into the application process.

–    Introduction and optimization of a robot for the stripe coat application process.

–   Investigation of coverage rates and dry film distributions over weld seams and bolts.
