An inward-oriented strategy was adopted for the Turkish maritime sector from 1923 – the foundation date of the Republic of Turkey – to 1952. A partially liberal policy was experienced beginning from 1952, and a planned development period has started since 1962. This study is aimed at investigating the principles and targets for the maritime sector beginning from the first five-year development plan to the current plan including 2013, and evaluating whether the stated targets have been achieved or not. Moreover it is also planned to investigate the maritime transportation and to state the new opportunities and current issues about Turkey briefly.

When the wet granular materials lose their shear strength they flow like fluids. This phenome-non is called liquefaction. The liquefaction can be prevented by means of limiting the moisture content of cargo by introducing the safety margin. Cargoes, which may liquefy shall only be accepted for loading when the actual moisture content of the cargo is less than its Transportable Moisture Limit (TML). It has been recognized that in some cargoes, moisture can gravity drain towards the bottom of the hold. The resulting much wetter bottom layer may therefore be prone to liquefaction and provoke instability of the entire cargo. To prevent sliding and shifting of ore concentrates in storage a biodegradable materials are added to the ore. The polymer materials absorb water from the ore particle’s pores and the moisture content goes down. In consequence polymer materials may prevent drainage of the water from the ore particle’s pore.

The maritime terminal design process is a complex stepwise series of strategic decisions involving the engagement of a relevant amount of resources. In fact operating conditions near the maximum ca-pacity cause congestion effects with negative consequences on regularity and quality service. Therefore, in order to maximise its effectiveness, a strong need of methodological support is required. With this aim the authors developed different methods and models capable of supporting some of these decisions: a regressive method for preliminary dimensioning of harbour terminals and a sea-side operation combinatorial model for traffic analysis and capacity estimation. They are able to be integrated in a chain of models taking into account dimensions and manoeuvrability of ships, terminal morphology, handling equipment, storage areas, etc., with the aim to support the planning process and operational management.

The studies on how a fire on board accidents may be prevented have been actively carried out at both the national and international levels. This paper provides an outlook on fire safety assessment concerning nitrates fertilizers in sea transport. The investigation was aimed at comparison two methods of classification and assignment to a packing group of solid fertilizers of class 5.1 of International Maritime Danger Goods Code. First research was conducted in accordance with the test method described in the United Nations Recommendations on the Transport of Dangerous Goods, Manual of Test and Criteria, Part III, 34.4.1 “Test for oxidizing solids”. The second method was the differential thermal analysis (DTA) where the basis was the determination the temperature change rate during thermal reaction. According to two used tests, the investigated fertilizers belong to 5.1 class and require to packaging group III of the International Maritime Danger Goods Code. The DTA method gives more quantitative information about fire risk on the ship than method recommended in International Maritime Danger Goods Code.

The economic and social impact of the waterborne sectors in Europe cannot be overstated, employing directly more than 3 million people and generating a turnover of about €250 billion representing more than 1% of the EU’s GDP. In order to maintain its leadership and competitiveness, Europe must take advantage of new market opportunities and address these challenges by means of focused research, development and innovation. In recent years the impact of digital technology and relevance of geospatial information has been increasingly felt across the whole maritime community bridging waterborne and coastal activities. The challenge for the maritime and marine science communities is to accelerate the transformation of the maritime sector into one that is able to exploit market-led opportunities and create high value added outputs that fully embraces technological and scientific advances. e-Maritime offers itself as the enabling framework.

The International Atomic Energy Agency (IAEA) estimates that 10 million shipments of radio-active materials are transported annually. Each shipment is made up of either a single package or a number of packages transported from one location to another. The vast majority of these shipments, some 95%, relate to non-fuel cycle transports such as the transport of smoke detectors, and cobalt sources for medical purposes. Only 5% relate to nuclear fuel cycle transports. This study investigates the safety stability aspect, harmonized regulation based transportation, sustaining shipment aspect for the transportation of radioactive materials by ships. Consequently the originality of this paper appears the alignment of existing maritime rules and regulations with the IAEA regulations in order to provide easy understanding and usage for the establishment of code of safe and secure practices for seafarers with the countermeasures and harmonized regulations that are practically implemented by the navigation officers and Master.
