Tytuł:: Approximate method of calculation of the wind action on a bulk carrier

Data publikacji:: 2014
Wydawca:: Akademia Morska w Szczecinie. Wydawnictwo AMSz
Tematy:: bulk carrier
approximate method of wind action
approximation of surface and resistance
Opis:: While a ship is sailing, wind is acting upon the ship hull above water. As a result, additional resistance, as well as transfer drift force and drift moment emerge. The article presents an approximate method of calculating these forces for bulk carriers, in the form useful at preliminary ship design, when only basis ship dimensions are known.

Tytuł:: A method of calculation of ship resistance on calm water useful at preliminary stages of ship design
Autorzy:: Żelazny, K.
Powiązania:: https://bibliotekanauki.pl/articles/359058.pdf
Data publikacji:: 2014
Wydawca:: Akademia Morska w Szczecinie. Wydawnictwo AMSz
Tematy:: approximate method of resistance calculation
bulk carrier
multiple linear regression
Opis:: During preliminary stages of ship design, decisions on ship properties are made only with little knowledge on ship hull geometry – a ship designer has only the basis dimensions at his disposal. Therefore on these initial stages of ship design, methods of calculation of ship properties (eg. resistance) on the basis of basic design criteria are indispensable. The article presents a new method of calculation of bulk carriers resistance which proves exact even with a minimum number of geometrical parameters of a ship’s hull.

Tytuł:: An approximate method for calculation of mean statistical value of ship service speed on a given shipping line, useful in preliminary design stage
Autorzy:: Żelazny, K.
Powiązania:: https://bibliotekanauki.pl/articles/259679.pdf
Data publikacji:: 2015
Wydawca:: Politechnika Gdańska. Wydział Inżynierii Mechanicznej i Okrętownictwa
Tematy:: service speed
shipping lines
preliminary design
Opis:: During ship design, its service speed is one of the crucial parameters which decide on future economic effects. As sufficiently exact calculation methods applicable to preliminary design stage are lacking the so called contract speed which a ship reaches in calm water is usually applied. In the paper [11] a parametric method for calculation of total ship resistance in actual weather conditions (wind, waves, sea current), was presented. This paper presents a parametric model of ship propulsion system (screw propeller - propulsion engine) as well as a calculation method, based on both models, of mean statistical value of ship service speed in seasonal weather conditions occurring on shipping lines. The method makes use of only basic design parameters and may be applied in preliminary design stage.

Tytuł:: Approximate Method of Calculating Forces on Rudder During Ship Sailing on a Shipping Route
Autorzy:: Żelazny, K.

Opis:: Service speed of a ship in real weather conditions is a basic design parameter. Forecasting of this speed at preliminary design stage is made difficult by the lack of simple but at the same accurate models of forces acting upon a ship sailing on a preset shipping route. The article presents a model for calculating forces and moment on plane rudder, useful for forecasting of ship service speed at preliminary stages of ship design.
