A Robot for Welding Inspection in Offshore Mooring Chains [PDF]
, 2018 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 way. The robot is divided in three parts: global position-ing subsystem, local positioning subsystem and inspection subsystem ...

Effectiveness of Moorings Constructed from Rope in Reducing Impacts to Seagrass
Oceans, 2022 Seagrass meadows commonly reside in shallow sheltered coastal environments which are typically safe havens for mooring boats. There is evidence from around the globe that the use of common swinging chain moorings leads to halos of bare sediment in ...

Verification of a Numerical Simulation Code for Underwater Chain Mooring [PDF]
Archive of Mechanical Engineering, 2016 Abstract Numerical simulation is an economical and effective method in the field of marine engineering. The dynamics of mooring cables has been analysed by a numerical simulation code that was created on a basis of a new element frame. This paper aims at verifying the accuracy of the numerical simulation code through comparisons with both the real ...

Tracked-wheel crawler robot for vertically aligned mooring chain climbing design, simulation and validation of a climbing robot for mooring chains [PDF]
2017 IEEE International Conference on Industrial and Information Systems (ICIIS), 2017 Only a few attempts have been made to investigate the possibilities of developing chain climbing robot due to the complexity of the structure and physical nature of chain links. Mooring chains are subjected to large tidal waves, harsh environmental conditions and storms on a daily basis. Therefore, periodic inspection of the integrity of chain links is
