As a New Concept in Ship Design to be Alternative of Ballast Water System, to Emerge that Remedy the Introduction of Invasive Marine Species and the Disadvantages of Ballast Water Treatment Systems. the Non-Ballast Ship has been Studied Abroad, but it is Rarely Mentioned in China. in this Paper, the Hydrodynamic Influences due to Hull Line Variation of this Kind of Ships were Studied, Using the Method of Invariant Cross-Section Area Curve under the Design Draft to Change the Rise Angle at Bottom. then by Using Numerical Calculation, get the Resistance and Effective Power at each Angle.

Resistance Performance

In this paper a new concept in ship design was used to be alternative of ballast water system, to emerge that remedy the introduction of invasive marine species and the disadvantages of ballast water treatment systems.Thus, the hydrodynamic influences due to hull line variation of this kind of ships were studied, using the invariant cross-section area curve under the design draft to change the rise angle at bottom. Then numerical calculation was used to get the resistance and effective power at each angle. Two 3D models were constructed for 59000 DWT oil tankers and 35000 DWT bulk carriers, where the result of the bulk carrier was exposed.

To eliminate the introduction of invasive marine species and the disadvantages of ballast water (BW) treatment systems a new concept in ship design was developed to be alternative of ballast water system. Non-Ballast ships were rarely mentioned in China even they were studied widely worldwide. In this paper, the different types of non-ballast water ship were reviewed, to be classified in order to facilitate the study of such types of vessels and serve as a base for the development.

In this article, monitoring of ballast water after its treatment by any of BWTS (Ballast Water Treatment System) on board ships has been analyzed. The efficiency of those systems has shown to be the major problem as there are no systems for tracking ship ballast operations. The overall aim of the study was to emphasize the necessity of monitoring the ballast water treatment on board ships and to propose a solution. The flow cytometry technology and applications of flow cytometers have been analyzed as well. The functionality and possibility of using this technology for detection of the treated ballast water quality has been explained. The results of the flow cytometry detection have been confirmed mathematically. The possibility of finding the remaining microorganisms in the treated ballast water has been calculated and the result was a very high percentage of 82%. The study presented in this paper aids in the understanding of how important it is for results of the ballast water treatment systems operation to be monitored since such monitoring is also in the interest of protecting the environment.
