A method for determining stability of a vehicle having a load suspended from the vehicle is provided. The method can include obtaining measurements from a plurality of sensors positioned on the vehicle, obtaining a measurement from a vehicle accelerometer operative to determine an inclination of the vehicle, determining a position of the load suspended from the vehicle, determining a slung load of the load suspended from the vehicle, using the determined slung load and the determined position of the load suspended from the vehicle, determining tipping moments acting on the vehicle, determining righting moments acting on the vehicle and determining a tipping stability based on the determined tipping moments and determined righting moments.

Technologies are described for a pipe cover and method of covering a pipe. The pipe cover comprises a cover having a first side, top, second side and an open bottom and is configured to receive an end portion of a pipe into the open bottom and between the first and second side. The first side, top, and second side are configured to extend beyond a terminal end of the pipe to be covered. A first clamping mechanism is on the first side and a second clamping mechanism is on the second side, configured and disposed to clamp the cover onto the end portion of the pipe to be covered and cover the terminal end of the pipe.

These fixtures aid in installing, sealing and securing pipe. Specifically, the invention aids in mating bell & spigot joints and securely capping open pipe ends of standard polyvinyl chloride (PVC), polyethylene (PE), and acrylonitrile-butadiene-styrene (ABS) pipe products as well as non-plastic piping by enabling equalized full circumference pressure on pipe ends to nudge, seal and/or secure pipe ends during installation or decommissioning.

In one aspect there is provided a pipe spinner and lifter for supporting and rotating a cylindrical member having a longitudinal axis. The pipe spinner and lifter comprises a pair of jaws that pivot about a pivot member, to allow the pipe spinner and lifter to actuate between an open configuration and a closed configuration. A plurality of rollers are mounted on the jaws, each rotatable about a rolling axis. When the pipe spinner and lifter is in the closed configuration, the cylindrical member can be rotatably captured by the pipe spinner and lifter, allowing the cylindrical member to rotate about its longitudinal axis. Preferably, the plurality of rollers are arranged in a substantially mirrored arrangement on the jaws. More preferably, the rolling axis of each of the rollers is substantially parallel to the cylindrical member's longitudinal axis.

Techniques for implementing and/or operating a pipe deployment system including pipe deployment equipment, in which a pipe drum having spooled thereon a pipe segment is to be loaded on the pipe deployment equipment, and a pulling device to be secured to an unspooled section of the pipe segment to enable pulling force to be exerted thereon. The pulling device includes a first device leg, a second device leg parallel to the first device leg, and a device base extending between and secured the first device leg and the second device leg such that the device base is perpendicular to the first device leg and the second device leg and the device base is raised relative to a bottom surface of the first device leg and a bottom surface of the second device leg, in which the unspooled section of the pipe segment is to be disposed on the device base.

Techniques for implementing and/or operating a system that includes a flexible pipe, which is formed into a pipe coil, and a pipe heating apparatus. The pipe heating apparatus includes a bore device to be moved to a target position within the pipe bore of the flexible pipe to facilitate isolating a segment of the flexible pipe from a remainder of the flexible pipe, one or more heating conduits connected to the bore device such that the one or more heating conduits are disposed in an upstream region of the pipe bore behind the bore device, and one or more heat sources to be connected to the bore device via the one or more heating conduits to enable the one or more heating conduits to heat the segment of the flexible pipe to facilitate unwinding the segment of the flexible pipe from the pipe coil.

A support assembly for constructing and staging a pipeline for installation in a trench. The support assembly includes one or more stacks of support segments. A support segment for the support assembly. Method of using and making the support segments.
