Research Title:

Robotic Inspection of Mooring chains In Air and Water 


The idea is to inspect mooring chains that tie floating platforms to the sea bed with a wheeled permanent magnet adhesion robot that rapidly climbs the chain and deploy a robot arm with ultrasound probes around a link for possible defects such as cracks and corrosion. In particular, inspection of chains on FPSOs (Floating Production, Storage and Offloading vessels) robot is required to climb all the way from 30m below the surface up through the splash zone to the first link in the chain which is in air underneath the turret. The aim is to develop a lightweight robot that can be easily placed on a chain and retrieved quickly.
