RR31 - Development of design guidance for neoprene-lined clamps for offshore application Phase II

This report is concerned with a second phase of a Joint Industry Project (JIP) investigating the experimental slip capacity of neoprene-lined clamps. The use of such clamps in the offshore industry has been, and continues to be, widespread throughout the world. The following applications of such clamps may be given:

  • attachment of retrofitted appurtenances such as conductors and risers
  • temporary attachments for lifting purposes, especially pipelines
  • repair of damaged members (dented or corroded)
  • attachment of new structural members.

Neoprene-lined clamps contain a liner that lies between the clamp steelwork and the enclosed member. The liner provides tolerance against lack of fit of the clamp saddle around the tubular brace. In general, the linear is made of polychloroprene (neoprene) sheet that is bonded to the inner surface of the clamp saddle plates. The neoprene liner is usually plain for structural connections designed to transmit axial or rotational loads, although ribbed linings are sometimes used to accommodate potentially large lack of fit tolerances.
