AUV’s in Extreme Environments

An extreme environment exhibits extreme conditions which are challenging to most life forms.

An extreme environment is one place where humans generally do not live or could die there.

Examples of extreme environments include the geographic poles, deep ocean trenches, geothermal sites, minefields, war zones and adverse weather conditions

Hugin Trajectory

Pipeline tracking demonstration, 9-10 Feb 2011

30 km section of pipeline to/from Mongstad

8 hour HUGIN mission

Pass 1 (South to North):

Tracks planned from nautical charts

Follow pipeline at 80 m range

Transmit tracking output to surface

Record HISAS 1030 data

Pass 2 (North to South):

Travel directly over pipeline at low altitude

Use detections from pass 1 to position AUV

Manual tracking from EM 3002 data

Record EM 3002 and camera data

Real-time pipeline detection and tracking

Possible pipelines detected and tracked based on real-time side scan imagery from HISAS 1030

Most likely candidate selected based on prior information on position and orientation

HUGIN follows selected candidate at desired range (here: 80 m)

Selected tracks transmitted to surface on acoustic link (for demo purposes)

Tracks planned from nautical charts

HUGIN mission plan using pipeline as waypoints

Approximate knowledge of pipeline position sufficient – is adjusted by real-time pipeline tracking software in HUGIN

First half of mission executed with cross-track offset placing pipeline at optimal range for HISAS imaging
