28. On the structural response of bio-based adhesives for wooden hulls

Serena Bertagna (Università degli Studi di Trieste)

Material & production technology

Paper

In the last years, the idea of implementing “greener” and sustainable solutions merged with the basic principles of life cycle assessment concept has turned to be of paramount importance for the boatbuilding industry. In this framework, construction technologies based on wood such as strip-planking represent possible solutions, as they allow the use of a natural-grown material for attaining...

60. ENVIRONMENTALLY FRIENDLY COMPOSITES AND SURFACE TREATMENTS FOR METAL-TO-COMPOSITE HYBRID JOINTS FOR MARINE APPLICATION

Fabrizio Sarasini (University of Rome La Sapienza)

Material & production technology

Paper

Since early 1960s the marine industry has experienced an increasing use of composites from small boats to submarines. Traditional marine composites are woven glass/carbon reinforced thermosetting polyester/vinyl ester resins produced by hand lay-up, but the development of low-styrene emission resins, the vacuum resin infusion process and stitched fabrics have all contributed to improve...

74. Life Cycle Assessment in the naval sector: between certification and new materials

Mrs Barbara Busetto (MICAD)

Material & production technology

Paper

In recent years, the maritime sector has become increasingly interested in environmental sustainability issues, leading to the development of innovative technologies and materials. Seldom these solutions were analyzed with a life cycle approach and, when this has been done, the studies have been carried out without a reproducible methodology.
The lack of a standardized methodology based on...

97. Investigations on Ultimate Strength for a Container Vessel under Combined Loads

Dr Thomas Lindemann (University of Rostock, Chair of Ship Structures, Rostock, Germany)

15/06/2022, 18:00

Structural design

Paper

Ship structures are subjected to various types of loads during their lifetime. Different numerical methods exist to determine the ultimate bending moment of ships by taking the strength reduction of structural members into account. The Finite Element Method (FEM) as well as Smith’s method are feasible tools to perform progressive collapse analyses of large structural systems under...

106. Fracture mechanics properties of Al/Steel Structural Transition Joints for shipbuilding

Dr Pasqualino Corigliano (University of Messina, Department of Engineering)

15/06/2022, 18:20

Structural design

Paper

The need of lowering the weight of ships makes it crucial to have superstructures made of aluminum alloy and the ship hull made of steel. Within this context, the connection between the two different metals becomes crucial as different metals are hardly weldable using traditional techniques. Thus Structural Transition Joints are extremely important. One of the most promising welding techniques...
