Usually, the need for research arises when there is a discrepancy between theoretical and practical data. For example, RINA (Registro Italiano Navale) Rules describe two navigation areas yachts: unrestricted area with significant wave height of not more than 4 m. In GL (Germanischer Lloyd) Rules, it proposed to assign maximum that ship can meet, taking into account its speed design features. Th...

Simulating viscous flows with a free surface causes special difficulties, since its position will change continuously. Therefore, besides solving the Navier-Stokes equations, the position of the free surface must be determined every time step. In the present method, the Navier-Stokes equations are solved on a three-dimensional Cartesian grid. A Volume-of-Fluid function is used for the position ...

Objective: This study aims at investigating helicopter pilots’ strategies to achieve ship deck landing.Background: Helicopter maritime operations are challenging, especially when it comes landing on the moving decks of small ships, such as frigates, which can lead dramatic accidents.Method: Expert pilots were requested fly full maneuver from approach touchdown in an immersive simulator. Two sea...

The purpose of this study was to determine and analyze: 1) the effect female leadership style on work discipline, 2) performance, 3) discipline performance. This type research is causal associative quantitative with a survey approach. In study, saturated sampling technique used because all members population were sampled as many 60 ship crews where there leader.This conducted leaders/officers c...

The Diamond Princess cruise ship is a unique COVID-19 transmission case because of the high testing capacity and confined environment. This exploratory study aims to raise hypothesis regarding role poor ventilation systems in spread by analysing count data collected onboard clinic during outbreak, considering deck plan design air conditioning system ship. Observed symptomatic infection rate aft...

Investigating the loss of integrity (E) in cabin walls and decks, as well role insulation capabilities, holds significant implications for preventing serious human, economic environmental damage caused by ignition cabins ships ocean platforms due to fires explosions. In this study, fire resistance A-60 class ship bulkheads decks was evaluated through two groups standard tests. first test, steel...

Aging wooden structures in cultural heritage will inevitably need an improved support. A sensible design necessitates a numerical model of the structure to estimate stresses and displacements order evaluate support design. In present work full-scale finite-element 17th-century warship Vasa has been developed. Experiences from this exercise may be use making choices development models for other ...
