The effects of underwater currents on divers’ performance and safety


Underwater currents can produce considerable forces which affect not only divers themselves, but also their diving umbilicals, together with any hoses and cables running from the surface to equipment and tools the divers may have at working depth.  Tides and currents also affect the diving vessel or platform from which the diving is being conducted.

For many years the offshore diving industry has relied on the information and guidance on underwater currents contained in AODC 047 The Effects of Underwater Currents on Divers’ Performance and Safety to help keep its divers safe and productive.  This document updates and supersedes AODC 047 which is withdrawn.
