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

Ships have carried solid ballast for thousands of years in the form of rocks, sand or metal. In modern times, ships use water as ballast. It is more easier to load on and off a ship and more efficient and economical than solid ones. Ship fills with ballast water when it is empty of cargo, and the ballast water is discharged when it loads cargo. In ballast water ,there are hundreds of organisms carried that cause problematic ecological effects outside of their natural range. Preventing the transfer of invasive species and coordinating a timely and effective response to invasions require cooperation and collaboration between governments. Considerable efforts had already made to formulate appropriate standards for ballast water management during the convention development process. Overview

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

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.
