A method of testing installation of a module on an elongate member

Abstract

A method of testing installation of a module on an elongate member 12, wherein the module comprises at least two module parts (14, 16) configured to be assembled to one another around the elongate member, together forming a through-going passage 21 for receiving the elongate member, at least one resiliently deformable seat 30, 32 within the through-going passage for seating upon the elongate member, and an arrangement for securing the module parts to one another, which may take the form of straps 24, 26, the module comprising a channel 34 extending from an outer surface of the module to the through-going passage 21, and the method comprising: assembling the module parts about the elongate member and securing them to one another using the said arrangement; inserting a test rod (36) into the channel until an end of the test rod contacts the elongate member within the through-going passage, and determining whether depth of insertion of the test rod is consistent with proper installation of the module. Aspects include a module for installation on an elongate member, the module may be a distributed buoyancy module (or ballast or sensor module) intended for mounting on some form of underwater elongate member.
