An articulated assembly 1 for insertion into pipelines, the articulated assembly 1 comprising four modules 2 being connected together by respective joint devices 4, and a operating system including transfer means (not shown). The models 2 may typically comprise features such as a bumper nose 6 disposed at each end of the assembly 1, an array of roller wheels 8, packing sections 10 and plugging discs 12. The transfer means of the operating system may comprise power cables such as hydraulic lines and electrical lines as well as control lines, management lines and communication lines, which all form part of the operating system of the articulated assembly. The arrangement of the articulated assembly 1 is such that the joint devices 4 provide protection for the transfer means. The protection is achieved by extending the transfer means through the structure of the joint devices 4. Therefore, the joint devices 4 have a dual function of providing articulation means for the modules and protection means for the operating system of the assembly 1. |
