Voyage optimization is a technology to predict the ship performance in various sea states and current conditions, and based on the performance of the ship to assist ship masters in route selection. The targets of increasing energy efficiency and reducing Green House Gas (GHG) emission in the shipping industry can be achieved by voyage optimization. However, the practical and accurate prediction...

A model of oil tanker casualties is presented which permits an e.upected casualty ratefor each tanker to be calculated based on its age and casualty history. These expected rates are shown co be good predictors of both the actual cosuoly expertence and the probability of total loss. The model is based on thefindings that 1) the casualty behavior of an individual tankerfollows a Poisson distrtbu...

Abstract This paper proposes a semi-empirical model to predict ship’s speed loss at arbitrary wave heading. In the model, formulas that estimate added resistance due waves attacking from different heading angles have been further developed. A correction factor is proposed consider nonlinear effect large in power estimation. The are developed and verified by tests of 5 ships regular with various...

The application of strengths, weaknesses, opportunities and threats (SWOT) analysis to formulation of strategy concerned with the safe carriage of bulk liquid chemicals in maritime tankers was examined in this study. A qualitative investigation using SWOT analysis has been implemented successfully for ships that are designed to carry liquid chemicals in bulk. The originality of this study lies ...

The armed aggression of the Russian Federation against Ukraine led to destruction critical infrastructure, termination port operations in Ukraine, disruption regional logistics, rise fuel prices, and increase ship cargo insurance costs. It contributed restriction trade Black Sea region. hinders changes logistics throughout As a result, search for alternative routes Ukrainian goods quickly incre...

In risk assessment of maritime transportation, estimation of accidental oil outflow from tankers is important for assessing environmental impacts. However, there typically is limited data concerning the specific structural design and tank arrangement of ships operating in a given area. Moreover, there is uncertainty about the accident scenarios potentially emerging from ship encounters. This pa...

It is of the utmost importance to accurately estimate different ships’ weights during their design stages. Additionally, lightship displacement (LD) data are not always easily accessible shipping stakeholders, while other dimensions within hand’s reach (for example, through from online Automatic Identification System (AIS)). Therefore, determining might be a difficult task, and it traditionally...

The Middle East has always been of interest to other countries for its geopolitical position and its vast supply of oil and gas. Meanwhile, the issue of the transfer of oil by sea is of great importance. The Strait of Hormuz is perhaps one of the most important blue-water in the world due to the geographical location of the Persian Gulf to the Free Seas. The world's superpowers, like the United...
