In recent years the world's thirst for oil has led the oil companies to explore in deeper and deeper offshore waters. This search has been made possible by improved diving techniques and has itself generated further developments. The topics covered include:

• The increased pressure underwater and the reasons for slow decompression on the return to the surface
• Decompression tables and surface recompression
• The problems of buoyancy and the threat to divers of all water movements
• The use of the wet bell
• The problems of breathing air underwater and the reasons for using heliox
• The problems of breathing heliox
• The theory and practice of saturation diving
• The use of the diving bell
• The remote controlled vehicle
• Diving emergencies
• What steps should be taken by people working near divers to ensure the safety of the diving operations

Divers are professionals. They are an essential but vulnerable part of any offshore team. They are strangers in a totally hostile environment. With the aid of technology and training they are able to work there. They do not need unnecessary hazards. Everyone on an installation has a contribution to make to keep any diving operations as safe as possible.
