One Man 1 Atmosphere Submersible, also known as OMAS SPIDER

The Spider 'Atmospheric' Diving Suit was produced in the 1970s for exploration and maintenance work in the North Sea. The Spider had a depth rating of 2000 feet and was used in many deep operations mainly from drilling rigs. It had an eclectically insulated GRP body and a Plexiglas hemispherical dome. The diver could operate articulated arms with powered claws capable of various tasks. Six variable direction motors and thrusters provide propulsion . For static operations there are suction pads for gripping smooth surfaces.

Atmospheric Diving Suits normally work in pairs for safety reasons to help release the trapped vehicle should this occur. This also enables round the clock operations.
The Spider was easily moveable and could be deployed very quickly. Apart from work in the Petrochemical industry it could be used for salvage and rescue work. The diver in the vehicle breathes normal air so could work for long periods sometimes eight hours a day without costly saturation diving systems. It was used until 1982 when it was replaced by the Draeger-Newt suit suit , designed by Dr Phil Nuytten from Canada.
