Abstract: The present invention addresses to equipment for collecting flexible pipes without the use of special vessels, using less costly resources and which are not committed to not damaging such equipment during handling, since it is applied to pipes at the end of their useful life or that are already damaged. These types of pipes represent a major liability for some oil industry operators. The technology to be used, in phases of demobilization of fields or even for collecting pipes with no prospect of use, uses vessels with minimal adaptations that rely on the presence of collecting/launching wheels with a much smaller diameter when compared to the wheels used in conventional vessels or, alternatively, the launch of a special collection coil with its own traction means to make it possible to wind the abandoned pipes, in the same place where they are launched, with subsequent collection of the set and transshipment to the vessel itself.

Abstract: The present invention relates to devices for repairing hoses of umbilicals. In this context, the present invention provides a device for repairing a hose (3) of an umbilical, comprising a tubular repair body (1) and a fusible element (2) adapted to obstruct the passage of fluid through the inside of the repair body (1), wherein the repair body (1) comprises an outside diameter that matches the internal diameter of the hose (3) to be repaired.

Abstract: The present invention addresses to a blanket for thermal insulation of submarine pipelines to favor the maintenance of temperatures above the desired minimum in the respective designs, since the fluids internally transported tend to lose heat to the environment. It solves problems that occur with the formation of paraffins or scales, the increase in oil viscosity and the formation of hydrate, among others. The invention must be launched at greater depths (where the external temperature is lower) and close to the origin of the fluids, where these will have the maximum temperature and, as this variation will be maximum, the thermal exchange potential will be more intense. The blanket then keeps the water heated by the pipeline confined to the surroundings thereof, acting as additional insulation. In addition, it is installed longitudinally on the pipelines in which it operates, by being unwound (to facilitate installation).

Abstract: The present invention proposes a split clamp (7), typical of trepanning operations in pipes, which allows the intervention with a tool (3) that makes a circular hole in the pipe (1) under analysis, removing layer by layer, until reaching the pressure barrier (2). With this, a sample of the layer of interest is removed to be forwarded for analysis. Such a clamp (7) has means to isolate the pipe (1) from the external environment, introduce the tool (3) and remove the same with the sample, also allowing tightness repair of the pipe (1).

Abstract: The present invention addresses to a system for removing hydrates and other scales in subsea pipes in oil production fields. More specifically, the present invention addresses to a system for fighting and removing hydrates and other scales comprising independent traction modules, equipped with load cells that act by controlling other traction modules, wherein said traction modules are interconnected intercalated with armored cable sections. The system of the present invention is applied in rigid or flexible pipes that present restrictions or blocks to the flow.

Abstract: The present invention relates to junction boxes for umbilicals. In this context, the present invention provides a junction box for connecting two umbilical sections, comprising a plurality of main pipes (2), suitable for individually connecting a plurality of hydraulic hoses (I) of a first umbilical section to a plurality of hydraulic hoses (I) of a second umbilical section, in which the junction box also comprises an auxiliary pipe network (3) hydraulically connecting all of the main pipes (2).
