Le confort à bord des grands yachts à moteur fait l'objet d'une attention particulière de la part des plus grandes Sociétés de Classification qui ont publié de nouvelles règles et règlements pour l'évaluation des niveaux sonores et de vibrations. Ces règles, généralement désignées comme «Règles de Classe Confort", contiennent les critères...

Il livello di comfort a bordo dei moderni superyacht è stato recentemente oggetto di attenzione da parte delle più importanti Società di Classifica che hanno emanato nuove direttive per la valutazione delle vibrazioni e del rumore. Tali direttive, indicate genericamente come "Comfort Class Rules" contengono sia i criteri per la misura delle...

The dynamic behaviour of hull structures has a great impact on the comfort level on board modern superyachts and, from the structural point of view, this is one of the subjects shipyards are more interested in. In addition many important Classification Societies have issued new rules and regulations for the evaluation of vibration maximum...

In this work a complete review of the existing yacht comfort rules is presented. Then a case study is presented, consisting in a 60 meters superyacht, on which a detailed FEM investigation has been carried out in order to investigate the dynamic behaviour of hull and superstructures. The results of modal and transient analyses are compared with...

High quality aesthetics is a de-facto necessity on luxury vessels such as large yachts. However, high thermal loads due to solar radiation cause uneven expansions in the hull. The classic colour of the conventional yacht fleet is thus unsurprisingly white. However, recent trends see owners opting for darker colours such as black, which absorb...

Structure-borne noise generated by diesel engines on board ships is strictly related to the intrinsic dynamic characteristics of both diesel engine and engine supporting system. To keep the structure-borne noise at low levels, the selection of the most suitable structural configuration of the engine foundation is one of the main aims of the...

Crash in high speed vessels has more in common with automotive accidents that those of slower larger vessels. A computer simulation model was developed to predict the structural damage and the injuries to ship crew and passengers, in the event of a 40knot crash of the CLF with a harbour structure. The work involved reviewing and implementing...

Understanding the methods to evaluate the comfort on board ships through direct measurements of the vibration levels is crucial for obtaining accurate results, and so a clarifying explanation of the methods required by the ISO 6954:1984 would be useful. The checking is performed using a Maximum Repetitive Value (MRV) that is not clearly...
