Plastics processor Trelleborg worked with offshore construction company McDermott to develop a new range of diver-friendly piggyback clamp designed to improve safety during installation of underwater pipelines. Molded from marine-grade polypropylene, the piggyback saddle can fit carrier pipelines from 20" - 42" and line sizes from 1.25" to 3.5". The one-size-fits-all design of the clamp can streamline purchasing, enabling zero-waste bulk ordering.

Polypropylene clips a safety win for professional divers

Business unit Trelleborg Offshore developed the clamp at the request of McDermott. The new PP system includes the use of

edge-treated banding and a new fastening system which eliminates sharp edges, reducing the risk of cuts to a diver. The design also negates the need to pass the band around the carrier pipe to secure the piggyback line, which reduces handling and improves installation efficiency while also reducing costs and increasing diver safety.

Sean Brunton, operations manager at the diving division of McDermott, commented, "Improving diver safety is something that is of paramount importance to us and the Trelleborg piggyback clamp has been central to our Zero Hand Injury Campaign," with the company even giving its annual President's Award to Trelleborg for its efforts.
