Imotus-T AUV


About Imotus-T

Imotus-T is an autonomous vehicle designed to inspect the floor of in-service above-ground storage tank floors to API-653.

Using proprietary Simultaneous Localization and Mapping (SLAM) algorithms developed on Imotus-1, Imotus-T can map and navigate inside an AST with no prior knowledge of the tank.

After an initial mapping phase, Imotus-T will complete an autonomous survey of the tank floor, including the annulus weld using a specially developed ultrasonic thickness tool.

Imotus-T is initially available for production water and non-explosive fluids.  A fully ATEX certified vehicle is under development for use in all hydrocarbon tanks.
