context_page_description: Surface supplied diving skills are the skills and procedures required for the safe operation and use of surface-supplied diving equipment. Besides these skills, which may be categorised as standard operating procedures, emergency procedures and rescue procedures, there are the actual working skills required to do the job, and the procedures for safe operation of the work equipment other than diving equipment that may be needed.
  Some of the skills are common to all types of surface-supplied equipment and deployment modes, others are specific to the type of bell or stage, or to saturation diving. There are other skills required of divers which apply to the surface support function, and some of those are also mentioned here.
context_section_description: Surface decompression is more common with stage and wet bell diving, which provide a better controlled ascent and exit from the water, but the procedures are much the same as described above
