In installing ballast water treatment system, the cost of the system is high and many technical aspects are to be considered and also it takes significant time to retro-fitting on the existing ships. In addition, in the current circumstance which the Ballast Water Management Convention has not been entered into force, the 28th IMO Assembly adopted a resolution to mediate the implementation schedule of the treatment systems. In the mean time, California State and New York State have declared more stringent discharge requirements of ballast water and are planning to implement them earlier than the schedule of the Convention. In these circumstances, the implication in the difference between ballast water treatment system manufacturers and ship owners need to be considered. In this study, through the review on the considerations when installing the system onboard, stringent requirements of United States of America, and determent or mediated implementation schedules of Convention and California and New York States, the author would like to suggest the strategy of concerned parties for anticipated entrry into force of the Convention and implementation of the stringent requirements of United States of America.

As global warming continues, the rate of ice melting in polar regions is increasing rapidly. The interest related to north polar route is increasing among not only countries near Arctic ocean but also the other countries, In the past, the classification society rule related to a design and operation of ship operating in polar area has been primarily amended by Russia, Norway and Finland located near Artic area. However recently International Maritime Organization decided to legislate the Polar Code to ensure safety of a ship operating in Arctic and Antarctic Ocean, and it is scheduled to be completed until 2014. The present paper focuses on the survey of the current enactment trends of Polar Code and suggests the confrontational strategy in related organization.

This paper aims to investigated the origins and characteristics of flags of convenience(FOC) with International Ship Register(ISR), which was recently adopted by a few Western Europe countries(for example, Norway, U.K., France) and to compare FOC with ISR in terms of shipping policy, ship management, and expenses, and tax policy.

Two types of barge, container and tanker vessels, are designed with specific dimensions for canal-coastal shipping in Kyung-In canal and Yellow Sea region. The principal dimensions of barges are determined by considering the environment of Kyung-In canal and Yellow Sea. The selection of structure type and structure type and strength confirmation is conducted by the technical rules of Korean Register of Shipping. For the structural analysis of designed barges, the semi-direct stuctural analysis is carried out with using MSC NASTRAN software. Applying identical dimensions to both vessels, the standardization of structural design and analysis procedure are introduced.

In the recent International Maritime Organization's (IMOs) Maritime Safety Committee's 93rd session, the International Chamber of Shipping and International Parcel Tankers Association addressed marine fuel oil quality problems: increasing diluents in marine fuel oil, ignition in engine rooms due to the low flash point of fuel oil, and marine fuel oils that can damage marine engines. To deal with these marine fuel oil quality problems, the International Maritime Organization secretariat appointed the worlds marine fuel oil monitoring institute and constituted a correspondence group to determine the fuel oil quality required by MARPOL Annex VI regulation 14.8 (sulfur content less than 0.5%). In this study, basic research that can help with responding to marine fuel quality issues and the IMO's work is conducted. In order to perform this basic research, the off-spec ratio related to the fuel oil quality standard (ISO 8217:2012), density distribution tendency, gross specific energy, and correlation between components in the fuel oil are analyzed through actual marine fuel oil (residual marine fuel) data from the Port of Singapore.
