Improvements in systems for underwater work, an atmosphere substantially and autonomous underwater component for such systems

摘要

A dry and/or wet one-atmosphere underwater system for the recovery of natural resources, comprising pressure-resistant units containing the necessary/desired production equipment, including also control/habitat facilities, and connection (access) means between the pressure-resistant units. The units (7, 30, 33, 36) and the connection means (15) are components fitting into a modular (building-block) system with fastening (coupling) and access devices (8-11,19-22,31, 32, 34, 35, 37, 38) having measurements and distance (a) standardized according to the system, and the system further comprises an autonomous submarine (1) provided with corresponding fastening and access devices (2, 3, 14) having measurements and distance (a) standardized according to the system.
