Methods and systems are provided for a flexible support for a vehicle. In one example, the flexible support is formed of a composite material and configured to surround a vehicle component and absorb oscillations generated by the vehicle. The composite material may be a mixture of aluminum particles dispersed in an elastomer matrix.

An assembly, a system, and a method for protecting a portion of a pipeline from an impact in an excavation operation creating a void around the portion of the pipeline with a shell assembly are described. The shell assembly includes two half cylinders and fasteners to couple the two half cylinders together. Each half cylinder has a pipe cover shell, an inner shell, and an outer shell. The pipe cover shell is sized to conform to an outer surface of the pipeline. The inner shell is spaced apart from the pipe cover shell and coupled to the pipe cover shell by radially extended inner supports. Each inner support has a crumple component that is weaker than adjacent portions of the inner support. The outer shell is spaced apart from the inner shell with the inner shell disposed between the outer shell and the pipe cover shell.

A device (10) for protecting a mechanical part (20) against damage, in particular corrosion. The mechanical part bears on a support (22), or is under pressure as a result of weight. A flexible area (12) is designed to be in direct contact with the mechanical part and at least one row of rectilinear pads (14) designed to be in direct contact with the support. The row includes a plurality of pads (14-1, 14-2, 14-3) rigidly connected to the flexible area. The pads are more rigid than the flexible area, and are preferably rectangular in shape.
