Eliminate the Queuing Time in the New Suez Canal: Predicting Adjustment on Ships’ Arrival Time under Optimal Non-Queuing Toll Scheme

In 2016, the construction of the New Suez Canal was completed, enabling most large-size vessels to pass through and causing more ships to queue into the canal. As the queueing problem at the entrance of the canal was anticipated to be serious, an optimal non-queueing toll scheme was previously established to eliminate the queueing phenomenon at the anchorage of the canal. However, no information about each ship’s arrival time adjustment under the optimal non-queueing toll scheme is available from the previous literature. To solve this problem, we derive a series of mathematical formulae for each ship’s arrival time, length of queuing time and entry time before, and after, implementing the optimal non-queueing toll scheme. The arrival time adjustments, which enable ships to enter the canal without queueing, could then be obtained. These results enable the Suez Canal authorities to draw up the ship’s arrival timetable under the optimal non-queueing toll scheme, so that the captain could follow to enter the canal. The above information that we provide would be conducive to the management decision for the canal authorities to implement such a toll scheme. Once a tolled ship could enter the canal at the scheduled time without queueing, the ship owner could accurately control the sailing schedule, and the use of the ship could be more efficient.

Historical preconditions for the construction of the new Suez Canal and its political and economic significance

The Suez Canal has become a certain symbol of Egyptian patriotism; this fact is proved by an opening of a partial backup of themain watercourse of the Suez Canal in July 2015. The Suez Canal has allowed reconciling ideologicaland religiousdifferenceswithinthe country,unitingMuslimsand ChristianCopts.Atthepresent stage ofdevelopment,theEgyptian canal not only brings significant public funds to the country, but also provides additional jobs; and the slogans for its further expansion and transformation into a modern logistics center allow the Egyptians to recognize themselves as an important part of the global economy. Creation of large transport systems and nodes connected with the transit of natural resources and goods with high added value is an important article of income of any state, through the territory of which they pass. As noted by the Elbasy of the Republic of Kazakhstan Nazarbayev N.A., transport infrastructure is a blood system of the industrial economy and society [1]. Analysis of the features of the construction and operation of the Suez Canal demonstrates the basicapproaches to theproblems of creatingnew transport arteries

An Experimental Investigation of the Trim Effect on the Behaviour of a Containership in Shallow Water

A new division of the Suez Canal in Egypt, termed the New Suez Canal, was opened for international navigation in August 2015. It is therefore important to ensure the safety of ships navigating this new section of the canal. Measures to avoid grounding and/or drifting to the canal banks are necessary. Additionally, accurate prediction data for ship squat and under keel clearance is crucial. This paper presents the results of experimental work carried out at the Kelvin Hydrodynamic Laboratory at the University of Strathclyde, Glasgow, to study the effect of trim on containership sailing characteristics in shallow waters using Kriso Container Ship (KCS) model. A series of model tests were conducted to measure the resistance, sinkage variations with speed, water depth and loading conditions under different trimming angles at 1:75 scale. The objective of this work is to examine the range of ship trim for safe and efficient sailing in restricted water in both depth and width. The study also aimed to provide data to be used in validating numerical computations to be carried on the same type of vessel to detect the best trim angle for ships during sailing in restricted waters to reduce resistance and therefore fuel consumption. For depth Froude numbers higher than 0.4, the results show that the ship model sinkage is less for aft trim than for level trim or forward trim. Concurrently, it can be observed that there is less water resistance for aft trim than for forward trim, albeit level trim shows the least resistance. The test was conducted for one value of model draft which was 0.144 m. Side bank effect were also examined.

Genetic Monitoring and Molecular Phylogeny for Cymothoid Isopod Invasion in Egyptian Lake Qarun Fishes by Using adopted taxonomic marker (COI)

Different types of aquatic ecosystem is abundant by a lot of crustaceans. There are species adapted to maximum of temperature, pressure and salinity. Isopods are a marine parasitic organism and commonly live in warmer seas. They are feeding on blood. Several species settle in the buccal cavity of fish. Parasite became a morbidity case in lake Qarun, GAFRD (General Authority for fish resources development, Fish Statistics yearbook, 2015). DNA barcoding gene (COI gene) was used to make the genetic characterization for the invasive species of Cymothoidae, Cymothoidae sp and recorded in the Genbank. Constructing a phylogeny depending on the degree of similarity between the new record (LC138010.1) and the other records of Cymothoidae species in the Genebank then the environmental conditions were compared according to the analysis of the constructed tree. Suez canal is the primary resource for the fingers of mullet which transferred to Qarun Lake (salinity, 49 ppt). Ballast water have an environmental effect by transferring the alien species in the Suez Gulf which have a warm weather. This study suggests that the Cymothoidae is expanded invasive species came from its habitat regions to a closed lakes which have a similar condition of water environment, temperature and depth to live and to be a morbidity in Lake Quran. Ballast water is a risky way to transfer the invasive species to Suez Canal then New Suez Canal poses and lead to biodiversity risks. Using eDNA techniques to diagnose the invasive species is very important unit which must be established in general authorities of fish resources and development in Egypt and other countries which invaded by different alien species.

The implications of political decisions on the economic situation in Egypt: انعكاسات القرارات السياسية على الوضع الاقتصادي في مصر

During the ten years before the revolution of January 2011, Egypt experienced political and economic conditions. During the period of its rule, the political system tried to issue political decisions that served the system of government and its control without making decisions in favor of the citizen. The economic situation became intolerable. The volume of spending on health and education has declined, unemployment has increased, and politically there has been a falsification of voter turnout and abuse of power by the security forces, In the Brotherhood, the situation was worse than that of President Hosni Mubarak. Egypt's credit rating fell to low. The decrease in the credit rating means that Egypt's ability to pay its external and internal obligations has decreased. Unemployment indicators rose to 13.5% and poverty rates in Egypt rose to 25.5% in 2013 after official indicators showed that the poverty rate in Egypt was 23.5% During 2012. The volume of inflation rose to more than 17.5%, and the value of the local currency (Egyptian pound) declined and lost more than 18%. As for the economic situation under the current regime, there has been a quantum leap in the volume of national projects, which has influenced a series of positive political decisions. These include the establishment of the new Suez Canal, low-income housing projects and electricity sector restructuring projects, which gave a huge economic boost that led to the appreciation of the Egyptian pound against other foreign currencies
