Abstract: The present invention aims at developing a robot for applying coating in regions called “difficult access areas” of offshore platforms and ships, such as curved, vertical surfaces, or surfaces with negative inclination angles. The design concept was developed based on a low-weight painting system, integrated into a vehicle with magnetic shoes, which produces a constant magnetic force on the metallic surface, capable of guaranteeing the support of the vehicle in the different areas of application. The floating magnetic system aims at ensuring that the wheels have the necessary friction for the vehicle to move. The use of the equipment allows greater productivity, with agility and speed in the application of coatings, reduction of coating losses during the process, repeatability and guarantee of the thickness of the applied layer, in addition to allowing the application of the coating on vertical surfaces, with negative inclinations or curves.

Abstract: A safety system and method for hydro jetting guns capable of monitoring and interrupting a hydro jetting operation depending on movements detected out of predefined operating limits. In particular, the system described herein can include a gun adaptation assembly interconnected to a pressure and power box, and comprising at least two inertial measurement sensors, a support with a gun microcontroller, and a double trigger mechanism. The pressure and power box is provided with a junction box and a solenoid valve. The system can further include a user monitoring wearable. If a deviation from pre-established standards is detected that suggests malfunction, excessive working hours, and/or discomfort of an operator, the system acts immediately to interrupt the hydro jetting operation and ensure the safety of those involved.

Abstract: The present invention refers to a working assembly for a painting system, containing a mobile platform and a crank and slider-type oscillating mechanism, which reproduces movements transmitted to a shaft and that guides a paint gun, mimicking the process performed by painters. Thus, the mobile platform and the oscillating mechanism were designed to move unidirectionally over the surface, being able to move in two orthogonal directions and also to rotate in order to keep the platform level.

Abstract: The present invention refers to an automated painting system on oil ships, being executed by a mobile platform and an oscillating arm. The assembly only works due to the control of cables, winders and wheels. This approach is aimed at painting large vertical walls. The painting deck suspension uses four cables, each connected to a pivot on the mobile platform, and two fixed pivots plus four winders. The winders contain a servo motor in a synchronous serial network. The cables are made of reduced-weight polyethylene. Each cable is connected exclusively to one winder. Suspension is achieved with the aid of two adapted cranes and initialization through the addition of a giraffe-type crane.

Abstract: The present invention relates to the construction of Mecanum wheels for a robot-operated painting system. The wheels have special characteristics given the difficulties and obstacles where they will be used. They were designed to facilitate the movement of the painting system on vertical and horizontal walls and to avoid coating losses. The Mecanum wheels consist of a set of wheel covers that are used to secure the rollers. The rollers, arranged at 45° and in a cylindrical-convex shape, contain bearings passing through their central axis, and have rollers at the ends of the bearings. The magnetic base is placed between the two wheels, being at an optimal height to exert magnetic force against the surface and to be able to pass over obstacles. Mecanum wheel geometries and materials are designed to be inert to the coating.

Abstract: Additives are described for use in high solids content epoxy-based corrosion resistant coatings in liquid form, where such additives are composed by microcapsules containing a regenerating agent dispersed in an organic solvent. The coatings, when additivated with such dispersion, will have the ability to self-regenerate in the event of damages (cracks or scratches) to the applied and cured coating on the metal surface, preventing the propagation of corrosion on the exposed metal surface.
