This study aims to present a philosophical and quantitative perspective of propulsion system for large-scale hydrogen-fuelled liquid-hydrogen (LH2) tanker ship. Established methods are used evaluate the design performance an LH2-carrier JAMILA, ship designed with four cylindrical LH2 tanks bearing total capacity ∼280,000 m3 along cargo using boil-off as power fuel. Additionally, is evaluated ba...

Background: Water resource management is a strategic issue in Qom city. Water scarcity is one of the most critical concerns of industrial estates. This study aimed to evaluate wastewater management in the Shokuhieh industrial park of Qom province in 2013. Methods: This is a descriptive cross-sectional study done by visiting the industrial units in person, completing questionnaires and analyzin...

In order to explore the influence of soil force on rotary soil-engaging components during their operation, a kinetic parameter measurement system was developed via sensor strain technique. By taking single-sided compacting ridge device as an example, experiment carried out operation parameters and obtained variation law pinnae. ADAMS software used simulate under different experimental factors (...

Gradual growing trend of marine transportation oil inevitably results in accidental spills. The safety and preventive measures introduced internationally nationally resulted the reduction number spills amount releases to sea past decades. However, recent incidents show that are unpredictable events may cause significant damage environment, flora- fauna coastal communities. statistics ITOPF- Int...

Concerning the implementation of marketing philosophies and policies in shipping companies no extensive research has been made up to now. This article presents the application of marketing philosophies and policies to the companies, which are activated in merchant (tramp and liner) and passenger shipping. The emphasis is given to the merchant shipping companies due to the fact that the passenge...

Nomenclature ∆F0 = Bow wave disturbance force ∆pdr = Drogue position offsets from equilibrium position ∆pdr/pr = Position error between drogue and probe ∆pdr/pr (T ) = Terminal position error ∆Rdr/pr = Radial error between hose and drogue FT = Tanker joint frame Fr, Fhd = Disturbance forces on receiver and hose-drogue Fbow = Disturbance force from bow wave effect pdr (t), ppr (t) = Current posi...

A guidance and control system is introduced and applied to ship path following using two controls. The guidance system is derived through a waypoint guidance scheme based on line-of-sight projection algorithm and speed is controlled by a state feedback controller. An approach concerning the calculation of a dynamic line-of-sight vector norm is presented and the results are compared with the tra...

The optimisation of non-linear control systems by genetic algorithm is studied in this paper. It involves the performance of two systems for regulating the motion of a ship model. These systems allow Course Changing and Track Keeping through the implementation of a sliding mode controller. The genetic algorithm is used to optimise the performance of the complete system under various operating c...

Bu çalışmada, 21/07/2014 tarihinde Diyabakır Lice’ de gerçekleşen tanker kazasının fiziksel etkilerinin modellenmesi amaçlanmıştır. Kazada LPG yüklü tanker, Diyarbakır-Bingöl karayolunun 90'ıncı kilometresinde devrilmiş, 34 kişi hayatını kaybetmiş ve 36 yaralanmıştır. Kazanın modellenmesi, hem kazanın olduğu yaz mevsimi koşullarında örnek seçilen kış ALOHA yazılımı korelasyonlar kullanılarak ya...
