... ABSTRACT For modern shipbuilding, line heating is widely employed as an effective method to form complex double-curvature plates, and the shrinkage control method is the key to form the target plate. Taking sail plate forming as an example, heating simulation is realized by thermal elastic...

..., the hydrodynamic calculation is carried out, which the hydrodynamic parameters of the hull are allowed based on the potential flow theory. And then, we performed dynamic coupling analysis of pipe-laying vessel-mooring-pipeline. The influence of the stinger on the curvature radius of the pipe is considered...

.... In this study, the Consistent Particle Method (CPM) is enhanced by incorporating the continuum surface force (CSF) model and applied to simulate the oil spill process. Firstly, the advantage of CPM in computing the curvature of an interface, which is key in simulating the interfacial tension force...

... Abstract Traditional pipe-in-pipe systems installed by reel-lay are straightened on the lay-vessel. The process results in the inner and outer pipes having opposite residual moment and the inner pipe is under-straightened, which typically means hogging residual curvature in the sag bend...
