A robot for non-destructive testing weld inspection of offshore mooring chains
(SAGE Publications Inc., 2018-05-09)
Welding flaw detection is a key step in manufacturing many components. In offshore chains, every link is manufactured from a steel bar that is bent and the ends joined by flash butt welding. Ultrasonic inspection of the ...
A robot for welding inspection in offshore mooring chains
In this paper, the authors present the CIRUS robot. This automatic system uses a combination of pulse-echo and pitch and catch ultrasonic strategies for the inspection of the welded area of mooring chain links in an automatic ...
An active/passive joint for reconfiguration applications
In this paper, an active/passive reconfigurable 2R joint is presented. Direct and inverse kinematic problems and the force transmission are considered. The advantages of the current design show its superiority with respect ...
A Comparison of Numerical Approaches for the Design of Mooring Systems for Wave Energy Converters
This paper analyses the numerical outcome of applying three different well-known mooring design approaches to a floating wave energy converter, moored by means of four catenary lines. The approaches include: a linearized ...
