Abstract
JFE Engineering developed a proprietary ballast water management system (hereinafter abbreviated JFEBWMS.JFE BallastAce® is a registered trademark for the system of JFE Engineering Corp.) utilizing filter(s),two chemical agents, and Venturi tubes as a ballast water treatment system for ships. For practical application of the JFE-BWMS, JFE Engineering determined the optimum conditions for high efficiency treatment of the object aquatic organisms in studies from basic experiments through practical tests1,2).This paper describes the results of verification of the treatment performance of the JFEBWMS and an assessment of the environmental impact of the discharged ballast water in a series of experiments from land-based tests (treatment capacity: 350 m3/h) to an onboard test in which an actual 1000 m3/h JFEBWMS installed aboard a 47,000 DWT bulk carrier (DWT: Deadweight ton). These tests were conducted with the aim of commercializing the system, and conformed to the guidelines3,4) established by the International Maritime Organization (IMO). In all cases, satisfactory treatment results which satisfied the relevant discharge standards5) were obtained in these tests, and an assessment of the results showed that the system has no adverse impacts on the ship's crew and the shipboard environment or marine environment. These results demonstrated that the JFE-BWMS satisfies both treatment performance and safety requirements at a high level. The system received final approval from the IMO on March 23, 201010), and received type approval from the Japanese government on May 26, 2010.
