Abstract
Economical and political circumstances have been continuously pushing exploration and production of mineral resources. However, for much of the world, the best potential for major new oil and gas reserves lies beneath 450msw. Eventual welding repair operations at such depths can only be carried out by fully automatic systems, part of a diverless underwater working station. Such station should feature: flexibility inside the working cell, self-sufficiency and reduced distances for data transfer and proximity between control units and their executive counterparts. To achieve these objectives a repair station consisting of a submersible, alignement frames and a purpose built habitat has been proposed. This study presents a conceptual description of this repair station, its main elements, working procedures and development requirements to realize it.
