Conceptual and practical ship design

Paper

A number of seventeen models of Ferry in scale 1: 28.750 of 10250 ton displacement have been built at the Italian Model Basin, to be tested in the Emilio Castagneto towing tank N.2 at INM in Rome. The results of the tests have been collected in this report, delivered and presented in easy and useful form. The hull C.2054 has been used to build the whole Serie, the variations in the forms have...

49. SIMULATION APPLICATIONS

Mr Luca Isgrò (CETENA SPA)

Conceptual and practical ship design

Paper

One definition of simulation is: an approximate imitation of the operation of a process or a system.
But the simulation is a natural brain process, in fact human beings continuously create simulations in their mind using the imagination to understand and predict their actions. From the simple prediction of a simple event to the imagination of a performance before a sport or an artistic event,...

73. Fast estimation of the time-to-flood on simple geometries

Luca Braidotti (University of Trieste)

Stability, Seakeeping, Maneuverability

Paper

Time-to-flood is a key parameter during a flooding emergency. In particular, when dealing with complex geometries it is important to know the time required to fill the first flooded room, i.e. the damaged one. Here, a fast solution for the assessment of the time-to-flood of one or two parallelepiped rooms is proposed. The progressive flooding of the rooms is first simulated employing a...

72. A methodology for the hull forms design of a passenger catamaran for the Venice Lagoon

Mr Donato Padolecchia (University of Trieste)

15/06/2022, 15:30

Conceptual and practical ship design

Paper

The proper definition of the main geometric coefficients and the hull forms of a passenger catamaran must be carried out since the early stage design, due to its strong impact on the resistance, propulsion and the generated wave pattern. This is a primary concern especially in fragile environments, such as the Venice Lagoon, where waves increase erosion phenomena. In this work, a two-phase...

78. The inside story of COVID-19 pandemic on The Diamond Princess as the prime mover of present and future ship design studies

Mr Gennaro Arma (Captain at Princess Cruises. Santa Clarita, California (USA)), Mrs Angela Denise Peri (Naval Architect, PhD Student. Department of Architecture and Design (DAD), University of Genoa)

15/06/2022, 15:50

Conceptual and practical ship design

Paper

“..But this coronavirus has forced us into a new framework, within which we move without any ease: everything has new ways, everything appears as never seen, it's like finding yourself in an uncharted territory..” (G. Arma, 2020)

With these words Gennaro Arma, Captain of the Diamond Princess cruise ship, describes the very first moments following the detection of what would become the...
