SBM's (single/surface buoy mooring) are the pipelines that commercial oil tankers use to load oil in their holds. NB the diver is wearing a Beckman Swindell diving helmet - a poplular piece of equipment around this time and one of the earliest modern diving helmets.

Location: Saudia Arabia, Ju'Ayma SBM field.
