Understanding and calculating marine displacement is essential for the design and operation of ships. This tutorial delves into the formulas and calculations associated with marine displacement, focusing on length, breadth, draft, and block coefficient.
26 lis 2020 · Calculation Framework for Ship's Fuel Consumption in Voyage. In this paper, the fuel consumptions of some dry bulk carriers and container ships are selected, as shown in figure 2.
8 sty 2018 · This paper provides an algorithm to minimize the fixed ordering, purchase, and inventory-carrying costs associated with bunker fuel together with ship time costs; and environmental costs...
8 sty 2018 · Optimization of the sailing speed decreases the fuel cost because it is proportional to the sailing speed. In this study, the present fuel consumption formula has been improved by finding a formula that shows the change of the displacement of the ship according to the time.
For a displacement boat, speed is a function of waterline length. The maximum theoretical speed is ordinarily assumed to be 1.34 times the square root of the LWL. Speed to Length Ratio = Velocity in Knots Waterline Length = V LWL
The factors are calculated which analyze Beam vs. Displacement; Sail Area along with Displacement, Beam and Length; Displacement to Length; Self Righting Energy; and finally the Relative Areas of the Positive vs. the Negative Stability Curves.
HULL FORM AND GEOMETRY. Be familiar with ship classifications. Explain the difference between aerostatic, hydrostatic, and hydrodynamic support. Be familiar with the following types of marine vehicles: displacement ships, catamarans, planing vessels, hydrofoil, hovercraft, SWATH, and submarines.
