Provided is a microtrencher having a utility avoidance system that detects objects buried under the roadway, identifies whether the buried object is a utility and determines whether the buried utility is in the path of the cutting wheel. If the buried utility is in the path of the cutting wheel, an alert is sent to the operator, the vehicle is stopped, and/or the cutting wheel is raised in relation to the roadway. Also provided is a method of using the microtrencher to cut a microtrench in a roadway and to avoid cutting a buried utility in the path of the cutting wheel.

Provided is a microtrench fill comprising concrete, a polymer, and a colorant. Also provided is a method of using the microtrench fill to fill a microtrench in a street or walkway.

A separation duct for encompassing an elongate member. The duct includes longitudinal internal spacers extend longitudinally in a direction of a longitudinal axis of the duct. A longitudinal plane for each spacer is substantially parallel to the longitudinal plane of the other spacers. The spacers support the elongate member and resist slippage of the duct relative to the elongate member. The duct may be used to provide separation and protection for elongate members of a range of outside dimensions.

An intervention system is provided. The intervention system comprises a cable being configured to be lowered into a wellbore, said cable having an inner tube enclosing one or more electrical conductors, and an outer tube surrounding the inner tube. The intervention system further comprises a downhole tool being connected to a distal end of the cable and being configured to pull the cable into the wellbore.

The present disclosure describes an outer utility pipe having a first diameter. In a first embodiment, the present disclosure describes an inner liner having a second diameter. The second diameter is smaller than the first diameter. The inner liner is positioned inside the outer utility pipe such than an annular space is created between the inner liner and the outer utility pipe. The inner liner is configured to conduct fluid. The present disclosure describes a communication conduit positioned in the annular space between the inner liner and the outer utility pipe. The communication conduit is configured to receive one or more components, such as fiber optic cables, configured to transmit information. In a second embodiment without an inner liner or an annular space, the communication conduit is received by a channel cut in an inner diameter surface of the outer utility pipe.

A method for installing an offshore installation is provided, the method including: a) providing a pipe for connecting the offshore installation with another offshore installation or an onshore installation; b) arranging an electrical cable inside the pipe; c) determining a level at or above the seabed, wherein the pipe includes a first portion arranged below the determined level and a second portion arranged above the determined level, and wherein the electrical cable is arranged inside the pipe so as to form a gap with an inner wall of the pipe along the first and second portion; d) determining an amount of cooling liquid such that, when the cooling liquid has a first temperature, the cooling liquid fills the gap along the first portion of the pipe, wherein the second portion of the pipe is free of the cooling liquid, and when the cooling liquid cools the electrical cable.

A process for extruding a divided conduit comprising obtaining an extrusion die head, inserting a strip-shaped substrate into the extrusion die head such that the strip shaped substrate is located within the tip gap and extends at least partially out of the tip gap such that the longitudinal edges are located in the die gap, and flowing molten polymer through die gap, encapsulating the longitudinal edges of the strip-shaped substrate in molten polymer. The extrusion die head contains a tip region and a bushing. The tip region contains at least 2 tips separated by a tip gap. The bushing extends around the tip region and the distance between the tip region and the inner surface of the bushing is defined to be the die gap and the die gap varies around the bushing.

Space in a conduit having at least one cable therein which is surrounded by a duct is recovered by longitudinally cutting the duct and removing the duct from around the cable. The duct may be pulled out of the conduit and past a blade to affect the cutting, or a blade may be pulled through the conduit to cut the duct while still in the conduit.
