Ballast Water Management

AbstractThe introduction of invasive marine species into a new environment by ballast water attached to ship hulls has been identified as one of the four greatest threats to the world’s oceans. The other three are land-based sources of marine pollution, overexploitation of living marine resources, and physical alteration/destruction of marine habitat. Ballast is any material used to add weight to balance an object. One example includes the sandbags carried on conventional hot air balloons, which can be discarded to lighten the balloon’s load, allowing it to ascend. Ballast water is water carried by ships to ensure stability, trim, and structural integrity. Shipping moves over 80% of the world’s commodities and transfers approximately 3‐5 billion tons of ballast water internationally each year. A similar volume may also be transferred domestically within countries and regions each year. Ballast water is absolutely essential to the safe and efficient operation of modern shipping, providing balance and stability to unladen ships. However, it may also pose a serious ecological, economical, and health threat to the marine environment.Turkey is a Eurasian country that stretches across the Anatolian peninsula in western Asia and southeastern Europe. Turkey is surrounded by three seas: the Mediterranean Sea, the Black Sea, and the Aegean Sea. The Turkish straits that separate Europe and Asia are one of the busiest waterways of the world. Turkey has several ports and berthing facilities. The number of ships coming to ports or passing through the straits has been increasing in the last decade. Half of these ships are carrying ballast water. Turkey has not ratified the International Convention for the Control and Management of Ships’ Ballast Water and Sediments (BWM) as yet but will soon prepare ballast water strategies. This paper discusses two different topics: ship ballast water management strategies and treatment technologies. The authors recommend the best strategies for prevention of ship ballast water pollution in the Turkish straits and ports.

Ballast Water Management

The minimal ballast water crude oil tanker has the design of a trapezoidal-shape inclined bilge entirely instead of the regular U-shaped tanker, also known as the trapezoidal tanker, which reduces the amount of the ballast water. This type of ship does not only reduce the cost on ballast water management, but also is beneficial to the environment for reducing the risk of water pollution. Since it is a new design, there are no applicable specifications for the assessment of structural strength at present. In order to find out characteristics of the yielding and buckling strength of this type of ship, the strength of a conventional tanker and a trapezoidal tanker are calculated by a finite element method and then compared with a variety of cases. It can be seen that the trapezoidal tanker has lots of advantages in strength and lighting weight.

Ballast Water Management

Diagnostics in ballast water management is the main remedy to protect against the threat of spreading invasive species that can be carried in ships' ballast tanks. This phenomenon is getting better known and understood. New and more effective methods of preventing threats related to this are being developed. Procedures are created to ensure environmental safety in the face of ever-increasing transport by sea. The article characterizes both the background of the problem, basic diagnostic medics used in ballast water management, as well as procedures and basic techniques used to ensure the safety of the natural environment..

Ballast Water Management

Rapid and simple analytical methods for viable microorganism detection in ballast water are required to evaluate the efficiency of ballast water treatment system. During the course of systematic investigation of the cytotoxicity and apoptosis assays, it was found that the adenosine triphosphate (ATP) and luminescence based cell viability assay, in other word, an ATP assay was the most sensitive and applicable to ballast water management (BWM). The assay was applied to cultured microalgae samples, and it could detect the existence of 5 viable cells in 100 μl. Comparably low luminescent values were detected in two cultured diatom species than in cultured dinoflagellates. This result might be caused by the small cell volume in diatom species. Following a regression model between ATP concentration and cell volume, an ATP guideline (876 – 109246 relative luminescence units: RLU) was developed for the evaluation of treated ballast water. ATP assay was also applied to the evaluation of ballast water treatment system (BWTS). The luminescence value which obtained from the ATP assay also showed a good correlation with the presence of living natural plankton cells with comparably low luminescence values than the cultured species. The low ATP concentration in natural plankton cells may reflect a decline in their biological activity because of extended exposure to dark conditions. ATP assay could be a suitable method for the monitoring of ballast water management compliance even though the results of this study need further validation.

The Stability

Since the emergence of humanity, the marine environment has provided a safety net in many ways, has fostered socio-economic development, creating links between states, between continents. In the same time, it represents a priority source of food for a considerable percentage of the population. The same marine environment also creates solutions to current global problems, as a potential source of sustainable energy for the future. In recent decades, the stability of this ecosystem has been  considerably shaken by the various types of pollution resulting from human activities. The Black Sea is not immune to these results from economic activities, such as the transport of goods by water, which creates the context for the migration of living organisms from one geographical region to another. The threat of ecosystems has been intensified by the process of globalization, by changing the natural food chains following the accidental introduction of non- indigenous marine life by discharging ballast water from ship tanks. Risk assessment to limit the effects of this biohazard problem is the first step in a normal regional chain of action..
