An apparatus (1) for movement along a tower structure (11) is disclosed, the apparatus (1) being configured to be arranged at least partly circumferentially around the tower structure (11). The apparatus (1) comprises a plurality of sliding rails (2) and a frame structure comprising a plurality of frame elements (3). Each frame element (3) is slidably connected to at least one of the sliding rails (2), and the frame elements (3) and the sliding rails (2) are interconnected to form a scissor structure. An upwardly directed lifting force applied, by means of a hoisting mechanism (8), at connecting points (10) at or near positions where the frame elements (3) are connected to the sliding rails (2), in combination with gravity working on the frame structure, causes the frame elements (3) to slide along the sliding rails (2), thereby causing the scissor structure to contract or expand to adjust a diameter of the frame structure to an outer diameter of a tower structure (11) having the apparatus (1) mounted thereon.

The invention relates to an apparatus for applying a coating to a pipe. The apparatus includes a mounting means for mounting the apparatus to the pipe, an applicator for applying the coating to the pipe and a moving means for moving the applicator relative to the mounting means and around the pipe.

A system for applying a fiber matrix on a tubular member is provided. A mandrel, configured for atraumatic placement within the tubular member, is included. Methods for atraumatic placement of a mandrel into a tubular member are also provided.

Provided is a system controlling method that improves versatility of a surface treatment system. In the treatment system, for treating a surface of an object by a treatment machine while moving the treatment machine relative to the surface of the object by an action of a work robot, there is provided a trackless type work machine mounting the work robot on a self-propelled cart; and the work machine mounts a robot moving device for moving the work robot relative to the self-propelled cart at least in a height direction. A work area in which the object and the work machine are present is image-captured by a position determination camera. A control device recognizes relative positional relation between the object and the self-propelled cart based on image-captured data of the position determination camera and controls the self-propelled cart based on the recognized relative positional relation, whereby the work machine is moved to a designated work position near the object.

An apparatus configured to coat pipelines, in particular a cutback along a pipeline, having: a frame, which extends along a designated axis and is fixable with respect to the pipeline so as to arrange the designated axis parallel to the longitudinal axis of the pipeline; a carriage, which is supported by the frame, is movable along the designated axis with respect to the frame, and is configured to designated a heater and an applicator; an actuator configured to advance the carriage along the designated axis; and a control unit configured to select a travel distance for the carriage from a plurality of travel distances.

Embodiments of the invention include apparatus and methods for coating drug coated medical devices. In an embodiment, the invention includes a coating apparatus including a coating application unit. The coating application unit can include a fluid applicator having a lengthwise axis and a width. The fluid applicator can include a tip comprising a first face across the width of the fluid applicator. The first face of the fluid applicator can be oriented at an angle of from about 15 to about 75 degrees with respect to the lengthwise axis of the fluid applicator. The fluid applicator can define a second face intersecting the first face. The coating apparatus can further include a rotation mechanism and an axial motion mechanism. Other embodiments are also included herein.

A pipe conditioning tool comprising a drive unit to move the tool along a pipe and a work head rotatable about an axis of the pipe to condition a surface of the pipe, the drive unit includes a frame extending to opposite sides of the pipe, the frame having legs extending radially beyond the work head to provide support for the tool upon removal from said pipe.

A pile maintenance method, system, and apparatus including a shell configured to be opened and closed longitudinally such that the shell forms a chamber between a length of a pile and an inner surface of the shell when the shell is closed around the pile, at least one fixing member configured to fix the shell to the pile such that the shell is substantially centered on the pile, at least one sealing member provided proximate a bottom of the shell and configured to form a substantially watertight seal at a bottom of the chamber, a plurality of nozzles provided inside the shell and configured to spray one or more media onto the pile, and a drain outlet provided proximate the bottom of the shell and configured to drain contents from the chamber formed by the shell.

A system for maintaining conduits and pipes after their installation into a pipeline system used to transport material in a fluid or flowable form. The system includes a maintenance tool adopted for use inside the pipe, an umbilical attached to the maintenance tool for pulling the tool through the pipe; and a pluralities of bearings positioned around the umbilical in order to allow the tool to be pulled through the pipe around bends and turns in the pipe.

A method of applying a coating to at least a portion of a surface of a structure using reusable master path rules. The surface of the structure is identified to form surface data. A framework for the surface of the structure is generated using the surface data. The framework comprises a plurality of points. Reusable master path rules are created for a master path connecting the plurality of points. The master path is a continuous line representing a universal route for applying coatings to the surface. The coating is applied to the at least a portion of the surface of the structure using the reusable master path rules.
