The system includes a robot multi-jet system having a spray section, a drier section, and a catalyst section. The drier section includes a warm air blower, the catalyst section includes a photocatalyst tank, and the spray section includes a plurality of jet extensions. A first jet extension connected to the photocatalyst tank sprays a uniform layer of a photocatalyst through a first set of jets, and a second jet extension that is mechanically connected to the drier section and in fluid communication with the warm air blower is configured to spray a gas onto an inner surface of the glass tube with a second set of jets. Both the drier section and the catalyst section are mounted on wheels to move the system on the inner surface of the glass tube. A motor is electrically connected to a battery mounted within the robot and mounted to the wheels.

A system and method for coating marine pipeline weld joints and wet inspection of the applied coating is provided. The coating system includes an anti-corrosion coating including a fluorescent pigment to enhance inspection of the applied coating. The system also includes a robotic crawler for traversing inside the pipe and carrying a coating apparatus and inspection apparatus respectively configured to apply the coating on the weld joints and facilitate inspection of the wet coating. The coating apparatus comprises a spraying nozzle provided on a forward end of the robotic crawler and configured to spray coating onto on the surrounding circumferential pipe surface. The inspection apparatus includes an ultraviolet radiation emitter for activating the fluorescent pigment in the coating and a camera for providing a live image feed of the coated weld joint area to an operator computing station for inspection of the applied coating.

A pipeline reconditioning system and process is provided for reconditioning corroded or damaged pipelines. The reconditioning system includes a mobile topside unit storing and providing reservoirs and supplies of substances used in the pipeline reconditioning and the equipment for the reconditioning system, a management and towing units that are securely anchored in the pipeline at remote access points, and a towed delivery system array that includes a deployment sled that processes the substances and dispenses the reconditioning material, such as a composite epoxy resin with chopped glass or basalt filament fibers, between access points to the pipeline interior.

An air purging coater apparatus is disclosed for purging mixed components from the apparatus disposed in a pipeline at a pipeline site. The apparatus includes a remote-controlled apparatus for insertion within the pipeline at the pipeline site. The remote-controlled apparatus includes a drive for controllably moving the remote-controlled apparatus internally within the pipeline. A high-pressure mixing device defines a first and second inlet controllably connected to a pressurized and further pressurized source respectively of a first and second component. The high-pressure mixing device defines a high-pressure mixing chamber connected to the first and the second inlets for mixing together the first and second components. The high-pressure mixing device defines an outlet connected to the high-pressure mixing chamber for receiving a flow therethrough of the mixed components. A spin head defines an internal conical surface and a baffle so that the mixed components are applied to an inside surface of the pipeline. The high-pressure mixing device is controllably movable from an application disposition thereof to a purging disposition. In the purging disposition, the flow of the mixed components is terminated and a source of pressurized air flows into and through the first and second inlets and the high-pressure mixing chamber and the outlet for purging any residual mixed components from the high-pressure mixing device thereby avoiding any need for the use of a potentially hazardous solvent.

A system for applying a chemical agent within a pipe includes a skid assembly, moveable longitudinally within the pipe. The skid assembly has a bottom positionable on a bottom, internal portion of the pipe. A delivery nozzle is carried by the skid assembly and is coupleable to a chemical agent supply. A dispensing tip delivers a controlled stream of chemical agent within the pipe toward an internal surface of the pipe. The tip is held at or above a surface of fluid carried by the pipe while at least a portion of the skid assembly is positioned below the fluid surface. The dispensing tip is limited from delivering the chemical agent downwardly toward the bottom of the skid assembly such that the dispensing tip delivers the controlled stream of chemical agent upwardly away from the bottom surface of the pipe and upwardly away from the fluid surface.
