Embodiment

[0176] Autonomous underwater system 100, the purpose of which is to: be located within an area 107 involving oil and gas activities, in accordance with figure 1 Deployed on the seafloor is shown, wherein the modular autonomous underwater vehicle 102 moves along a preset route 106 based on the positioning of the base structure 103 and the pipeline 105 connecting the base structure to the surface platform 104 .

[0177]During the exploration mission 106, the modular autonomous underwater vehicle 102 obtains data about the marine environment and the integrity of the infrastructure in which it operates through its installed onboard sensors and / or sensors on the instrumentation module 206. After the end, return to the integrated underwater station 101 located on the seabed.

[0178] In particular, the area monitored by the autonomous underwater system 100 is about 4 kilometers wide, about 4 kilometers long, and about 1 kilometer deep.

[0179] The integrated underwater station 101...

Abstract

The autonomous underwater system for environmental monitoring (100) comprising a multidisciplinary underwater station (101) equipped with onboard instrumentation (202), at least one autonomous, modular underwater vehicle (102) movable inside an area to be monitored (107) along an assigned route 106 and at least one external instrumental modulus (206) which can be connected to said vehicle (102), wherein said multidisciplinary underwater station (101) comprises a docking area (204), an interface system (220), an equipping system (207) for supplying the vehicle (102) with instrumental modula (206) and a management system (201).

Description

technical field [0001] The present invention relates to an autonomous underwater system for continuous, in situ, long-term and large-scale environmental monitoring, in particular for measuring environmental parameters near the seabed and along the water column. Background technique [0002] Measuring environmental parameters in underwater environments implies particularly important activities, most importantly approaching hazardous areas, such as oil production areas. [0003] To perform environmental monitoring in the sea, regular measurement campaigns are usually carried out, instrumented and samples collected for subsequent laboratory analysis. This approach is clearly insufficient to guarantee a complete understanding of the dynamics of ongoing phenomena and cannot detect the occurrence of anomalous events during use. [0004] When a continuous observation capability is required, a permanent underwater observation station is employed which, with appropriate instrumentat...
