A cleaning system is for cleaning an interior of a subsea structure by use of fluid. The cleaning system has a subsea unit, the subsea unit typically including: a fluids inlet; a hydraulics inlet; a hose, the hose having a nozzle; a feeder for feeding the hose into the interior and for retracting the hose from the subsea structure; and a entry connector for connecting to the subsea structure to be cleaned, through which entry connector the hose may be fed to enter the subsea structure, and a hose reel configured to rotate around a first and a second axis. The rotation around the first axis is for feeding and retracting the water hose and the rotation around the second axis is for rotating the water hose around the its longitudinal axis. A method is for using the cleaning system.

Embodiments of a downhole tool spooling system of a spooled downhole tool string include an actuator connected to a measuring head of the string and configured to provide for controlled rotation of the measuring head. The measuring head may include more than one sheave, with the string being off vertical center when passing through the head. A controller may send a signal to the actuator to rotate the measuring head about a vertical axis of the head into different rotational positions. The actuator also may be configured to linearly move the measuring head in the transverse direction. The system may also include a spooling drum that is configured to rotate about its central vertical axis. The guide frame to which the actuator is connected may be a fixed guide frame or may be an adjustable guide frame that provides for vertical movement of the frame, a tilting movement, or both.

A cable retractor enclosure having a weighted cable pulley and cable pulley guide rails. The cable pulley is rotatable about a pivot and configured to translate along said grooves when a cable wrapped underneath is extracted from the cable retractor enclosure. The cable extends outside of the retractor enclosure from its upper end and provides a cable end plug that sits within a retractor module insert. Weights may be attached to the cable pulley in order to leverage gravitational forces, which result in a bias causing the cable to retract back into the enclosure. Friction forces against the extracted cable can be used to prevent the gravitational bias the cable pulley exerts (retraction forces) on the cable by bending the cable to lay flat onto a table surface.

A vehicle-mounted reel utility with a cable dispenser. The cable dispenser has a swivel-aiming feature for figure 8'ing the cable. The cable dispenser is mounted to a swivel mount located at a free end of a positioning arm. The cable dispenser rotates about a pivot end of the positioning arm from a position parallel to a lifting arm to a position perpendicular to the lifting arm, and vice versa. The cable dispenser is also pivotally mounted to the swivel mount, allowing the user to swivel the cable dispenser about a horizontal arc while maintaining the cable dispenser in a central lateral position relative to a reel or a vehicle during the swivel movement. A hydraulic circuit controls the cable dispenser and an actuator that controls movement of a brake wheel from a contact to non-contact position, to coordinate the stopping of the reel and cable dispensing by the cable dispenser.

A drive system for cleaning debris within a medical tube. The drive system includes a housing defining an interior and an elongated guide wire residing at least partially within the interior. A roller is disposed in said interior in frictional engagement with the guide wire, said roller being configured to rotate about an axis. The drive system also includes a motor operable to drive the roller in order to both advance or withdraw said guide wire via said frictional engagement therewith through said inlet.

A system includes a frame and a first pair of rollers coupled to a first side of the frame. The first pair of rollers is configured to support a first end of a pipe reel. The system also includes a first cradle disposed longitudinally between the first pair of rollers and a second pair of rollers coupled to a second side of the frame. The second pair of rollers is configured to support a second end of a pipe reel. The system also includes a second cradle disposed longitudinally between the second pair of rollers, a pipe guide coupled to a third side of the frame between the first and second sides, a pipe brake coupled to the frame, and a pipe re-spooler coupled to the frame.

A system for carrying a tether guide, including a counter-balanced support system with two pivot points, where a first pivot allows the tether guide to travel up and down and the second pivot allows the tether guide to match the tether angle. Both pivots may be passive pivots. A shuttle that carries the tether guide may be electronically cammed to follow variable pitch helical grooves of a winch drum as the tether guide traverses across the drum length.

A system includes a frame and a first pair of rollers coupled to a first side of the frame. The first pair of rollers is configured to support a first end of a pipe reel. The system also includes a first cradle disposed longitudinally between the first pair of rollers and a second pair of rollers coupled to a second side of the frame. The second pair of rollers is configured to support a second end of a pipe reel. The system also includes a second cradle disposed longitudinally between the second pair of rollers, a pipe guide coupled to a third side of the frame between the first and second sides, a pipe brake coupled to the frame, and a pipe re-spooler coupled to the frame.

Cable laying devices for use with aircraft that are airborne are provided, which use a cable spool to deliver cable along a landscape. These devices incorporate a braking means that is actuated by cable tension, a means for cutting the cable which is controlled remotely and/or a motorized winding mechanism.

A hose reel 1 comprising a rotatable hub 2 and a stationary stand 4, wherein rotatable hub is arranged to roll on or roll off a hose. A swivel arrangement 3 forms an axis around a central axis of the rotatable hub, wherein the swivel arrangement comprises a rotatable part connecting to the rotatable hub and a stationary part connecting to the stationary stand, and wherein the swivel arrangement forms a passage for fluid.
