The robot for inspecting ships signals an epoch-making paradigm change in maritime maintenance and surveying. It has been developed to perform all the fussy and often dangerous tasks. Derived from advanced technology, a package of functions are woven into the robot: detailed visual inspections, thickness measurements of hull plates, and detecting cracks, corrosion or other structural deformities. Adopting this latest independent sensors, cameras and navigation system the robot is able to function in an increasingly challenging environment both dry dock and at sea with the ship afloat. Commercially, the applications for this robot are first to have a standard check every three months, secondly this includes checks on the work being done by carpenters and shipwrights and looking again thoroughly around to see if there are any traceable points where water dripping out of unhealthy pipes would get under deck; and thirdly it is a measure of efficiency and quality costs on which something could make progress at an unparalleled rate over time.
