Development of requirements for materials and manufacturing technology for three-layer panels used as elements of hull structures

Abstract

 

One of the promising technologies for repairing hull structures is the application of three-layer panels (sandwich panels). This technology was first applied on a ship with RS class in 2018. The article contains the main results of research work aimed at introducing this technology into RS regulatory framework. A review of the existing types of three-layer panels has shown that steel three-layer panels with solid homogeneous aggregate (STP) are the most popular and practical, but not yet regulated by the RS Rules. Analysis of the requirements of a number of classification societies for the certification of STP materials and the assessment of the strength of structures repaired with their use has resulted in the proposals for adjusting the current RS normative documents.

 

Keywords: three-layer panels, sandwich plate system, SPS, composite materials, ship repair, RS Rules.
