Slewing, storage and securing of gas quads and ships

A contractor member has reported several near misses/incidents due to the positioning of quads, resulting in damage to regulator boxes and pillar valves. In order to address these incidents, the contractor has issued the following guidelines for storing quads on deck:

  • where possible no quads are to be stored with manifolds facing areas where loads are lifted inboard/outboard
  • consideration should be given to positioning the quads in the following way: Two quads facing each other with sufficient gap between to allow access to valves and to allow for protection to regulator boxes
  • under no circumstances should quads be lifted in rough weather conditions
  • regulators and whips should be disconnected from the quad prior to any movements
  • any lashing down of quads should be carried out by competent personnel but in all instances should be checked by the marine crew
