DEFINITION

Classification: 405/168.1

With causing or controlling the deformation of a line:

(under subclass 158) 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.

(1) Note. Included in this subclass is a step or means for bending a pipe from a coiled configuration to a substantially straight-line configuration or from a substantially straight-line configuration into a desired curved configuration.

156, for a step or means for altering or forming the cross-sectional configuration of a pipe or cable by machining or plastically deforming the same.

168.3, for pipe laying from a reel on a floating means.
