Why robotic inspections?

hazardous environment

© 2015 DEKRA Page 3

Drivers for trend to robotic inspections

safety first: prevent human entry (in vessels, boilers, tanks etc.)

minimization of asset downtime

cost reduction by avoiding cleaning, scaffolding, isolation, etc.

improved repeatability and traceability

electronic data recording

higher resolution and probability of detection (POD)

Challenge: Keep FPSOs and drillships safely off shore on station for extended periods

EM&I project: „No Drydock - Safely‟

1 day interruption of operation means 10 million $ loss

life extension of FPSOs due to low oil price required

Safety – use robotics wherever possible to save divers lifes

Main Isolation Valves are Safety Critical

Shall be inspected and function tested thoroughly

Inspection via the sea strainers is inadequate

specialized cameras inserted into the piping via an

inspection port

valve condition and function can be observed

isolation valve inspection from inside

Measurement of accumulation of ice platelets

due to basal melt of ice shelves

Key facts and requirements:

camera system needs to work at -40° Celsius

watertight camera and control unit required

small diameter for ease of drilling

high mobility required

no maintenance

Wrap-Up

robot inspection…

…will not replace all standard NDT and inspection methods

…can increase the options and the scope of inspection

…can safe money, if additional costs of standard inspection are very high

…can deliver better inspection results

…can reduce risks in hazardous environment

…will improve safety!
