Articulated liquid cargo vehicles transporting inflammable fuels and dangerous chemical products require special consideration when traveling on urban roads or cruising at highway speeds. The road safety and handling of these kinds of vehicles may be adversely affected when negotiating sharp turns or travelling on slippery roads, which may result in either lateral instabilities or complete roll...

Risk aggregation is the process of combining multiple individual risks to develop a better understanding overall risk on system. Different can have different consequences and units measure. This study contributes by presenting general method combine posed an Arctic ship accident. The considers ecological socio-economic potential oil spill, life-safety evacuation. Existing models for each conseq...

The United States Marine Corps (USMC) currently operates a fleet of KC130 aerial refueling tanker aircraft. This paper uses queuing and simulation models to examine the USMC KC130 tanker requirement, contrasts the results and explores the budgetary implications of alternative fleet requirements. This analysis finds that queuing models don’t account for some of the complexities of aerial refueli...

We compared Greece with Norway in ship-owning endeavors since 1900. revealed the common characteristics and properties of 2 countries, being admittedly top 13 positions till nowadays. also differences. The countries handled, however, phenomenon flags convenience differently. Both suffered disastrous events like Great War, 1929-1933 depression 2nd WW, which harmed—if not equally—their Merchant F...

Towing hook is one of the important components a tugboat. Its function to tow various types ships, namely containers, tanker and even barges. This activity affects undergo failure crack, especially support structure hook. Earlier research has analyzed stress characteristics, fatigue maximum stress, factor safety aimed both at whole profile tug. The aim determine value in brought by tensile load...

In this paper, CFD simulation results for a tanker model are compared with experimental data over a range of wave conditions to verify a capability to predict the sea-keeping performance of practical hull forms. CFD simulations are conducted using WISDAM-X code which is capable of unsteady RANS calculations in arbitrary wave conditions. Comparisons are made of unsteady surface pressures, added ...

The reduction of harmful emissions from the international shipping sector is necessary. On-board energy demand can be categorised as either: propulsion, or auxiliary services. Auxiliary services contribute a significant proportion demand, with major loads including: compressors, pumps, and HVAC (heating, ventilation, air-conditioning). Typically, this met using same fuel source main propulsion ...
