Class Information
Number: 405/168.1
Name: Hydraulic and earth engineering > Subterranean or submarine pipe or cable laying, retrieving, manipulating, or treating > Submerging, raising, or manipulating line of pipe or cable in or from marine environment > With causing or controlling the deformation of a line
Description: Method or apparatus wherein the conduit or string is in the form of an elongated member having a stress limit beyond which plastic deformation occurs, and a step or means is recited to either (a) ensure that the stress limit is not exceeded during placement of the string or conduit or (b) to straighten or otherwise alter the longitudinal configuration of the string or conduit as the same is transferred from a supply to its final position below the water surface.
