A. 3000 – inspection AUV rated to 10 000 ft (3000 m)

Synopsis :

ALISTAR 3000 is an Autonomous Underwater Vehicle (AUV) capable of executing a variety of inspection tasks on ultra deep Offshore oilfields.
Video, sonar and its hovering capabilities provide the vehicle unique capabilities to inspect underwater equipment and provides operators greater flexibility and overall faster operations. Inspection of pipelines, risers or mooring lines as well as Touch Down Monitoring and post-lay surveys are the typical tasks. ALISTAR 3000 offers the possibility of collecting video and sonar data during the inspection of underwater equipment and stocks the information for post processing data analysis. Compared to ROV or towed systems, both of which require important
infrastructure and equipment on board, ALISTAR 3000 does not need an umbilical and a winch.

Main advantages :
High stability, increasing acoustic sensors detection performance and reducing power consumption
Hovering capacity via its thrusters architecture (4 horizontal, 2 vertical & 2 lateral)
Easy deployment overseas from ISO containers (airlift capacity)
User friendly Mission Management System for mission planning, simulation, monitoring and replay
Open and flexible architecture enabling easy adaptation to various missions

Reduced operation time
Advanced hydrodynamic shape enabling high inspection speed
Un-tethered operation enabling independent motion of the vehicle from the support vessel (increased weather windows)

Reduced support vessel requirements
Autonomous operation liberates the support vessel to carry out parallel tasks
Light overall spread (no TMS, no winch, no umbilical)
No medium voltage requirement (vehicle powered by secondary batteries)
Reduced personnel requirements & associated logistics (no pilot required for 24hr operation
duration)

Specifications

Applications:
Deep water close visual inspection
