Enhanced geomatic techniques for the deformation survey of ship platings in a real environment

The hull is one of the most important parts of ships and its structural integrity has a fundamental role for the safety of navigation. Nowadays, it is generally built by welding several steel platings, so producing an initial deformation that can significantly affect the panel collapse behaviour. Several studies have shown that the maximum deflection amplitude and shape affect the panel ultimate strength capacity under both longitudinal and transverse compression. This paper focuses on the deformation survey of a ship plating, by the endorsement of photogrammetric technique. The main is to establish the shape and metric information of the plate panel deformation for ships in operational mode. The results and relevant insights are fully discussed.
