The Rotterdam Rules regulate both transport documents and the legal effect of the choice of document much more comprehensively than the existing maritime convention to bring international harmonization of issues relating to transport documents. The Rotterdam Rules use the generic term 'transport documents' rather than referring to specific title such as bills of lading, sea waybills. The generic term 'transport documents' allow four types of transport documents to be identified as follows. 1. negotiable 2. negotiable which dispense with surrender 3. non-negotiable which require surrender 4. non-negotiable. Each types of transport documents has its requirements to be satisfied. Also, the choice of transport documents affects legal effect. Thus parties to the contract of carriage not only need to know how the document will be classified at the time it is issued but also consider what the documents will bring legal consequences.

In accordance with adoption of new convention for the control of ship's ballast water at the diplomatic conference held in London Feb, 2004, every country has to regulate the ballast water and deposit matters. When this Resolution comes into effect in 2009, all vessels engaged in international voyage must have ballast water control program, ballast water records, equipments which are suitable to the standard of exchange and performance for the ballast water. This study estimates objectively their performances, merits and demerits of the ballast water treatment technique and exchanging techniques for safe operation of ships. It is desirable to design an equipment to control the ballast water using the brush-type vacuum suction nonstop reverse cleaning system to overcome the clogging phenomenon and the direct disc filtering to maximize filtering area for the optimum process considering biological availabilities. It will be expected to protect against marine pollution and to maintain clean sea if it is secured to develop new ballast water treatment techniques. And it will also be expected to cope with the Resolution and each regulation of the developed countries from the ballast water.

The revision of domestic laws is in progress according to the UN Convention on the Law of the Coastal Zone Management . Along with it, the governmental policies related to maritime environmental preservation, especially around coastal zones and public works have been promoted based on enviornment, swiftly changed from the old function-based style. Therefore, this report will point out the important aspects which should be considered whenever there is any project on the coastal zones, suggest and classify projects of reviving the nationwide coastal zones, and show how to planning , check and evaluate the necessary technologies for reviving the coastal zones. This research will track down the coastal zone management method based on the natural enviornment as one of the necessary process to check the coastal zone enviornment for effective operating of the coastal zone management equipment method, starting on August 9, 1999, and report the technologies related with it.

The International Maritime Organization (IMO) ballast water management agreement (International Convention for the Control and Management of Ship's Ballast Water and Sediments) came into force on September 8, 2017. This study evaluated the disinfection performance of electrolysis, UV treatment, and electrolysis + UV combined, to improve the treatment of zooplankton (size ≥ 50 ㎛), which is expected to strengthen the standards for biodegradation efficiency. Among the methods used, the disinfection time leading to 100% death was in the order: electrolysis > electrolysis + UV > UV process. For the same level of disinfection performance, the amount of electricity required for the electrolysis, UV, and electrolysis + UV processes were 1,300 W.s, 8,400 W.S, and 4,500 W.s, respectively. The combination of electrolysis + UV process for inactivation of zooplankton in ballast water did not show a synergic effect owing to the slow disinfection time and high power consumption.

The present SOLAS Convention has maintained safety regulations in a largely prescriptive form and this has become overly prescriptive now. The prescriptive rules do not properly reflect technical advances and changing environments in the maritime sector in a timely manner. The purpose of this study is to provide preliminary research to lay a foundation for the development of a new regulatory framework based on safety performance which is not a prescriptive rule making bases. This study reviewed the concept and characteristics of a minimum requirement, the implications of safety regulations in terms of strategic, commercial and technical aspects, the compensative correlation between constructional requirements and operational measures, the concept of safety with regard to final stage confirmation of functions, expansion of implementers and objects of safety regulations, and the balance between safety and environmental protection requirements. Based on these research, 10 principles for the rule formulation process has been suggested such as consideration on the hardware requirements and software requirement, the multi-stage approval concept, new safety concerns for complex shipboard systems, considerations on the human element, regulatory impact assessments and measures to reduce administrative burdens.

According to the United Nations Convention on the Law of the Sea (Article 94), the flag state must fulfill its overall role to ensure maritime safety and operate the ship inspection system as a related measure. The Korean government (Ministry of Ocean and Fisheries) has implemented policies for reducing marine accidents to promote maritime safety; however, the target goal has not been achieved. The ship inspection system is a measure to prevent marine accidents, and for the effective operation of the system, a sufficient understanding of the origin of the ship inspection system is required. In this study, the trend of the international ship inspection system was identified by analyzing ship inspection system origins and the history of the system's paradigm shift. The recent international ship inspection system paradigm confirms international standardization and the active safety management of ship companies are becoming increasingly prominent. Based on this, the introduction of the 'PDCA cycle-based self-inspection system' is presented to the current domestic ship inspection system. This is a new type of inspection system that establishes the roles of interested parties based on the basic philosophy of the ISO 9000 series to improve the ef ectiveness of maritime safety. Additionally, the necessity for a non-face-to-face ship inspection system has emerged because of the COVID-19 pandemic. Hence, the transition to a 'mobile application-based ship inspection system' is proposed to accommodate the rapid development of information communications technology.

The Ballast Water Management Convention provides that ballast water treatment systems which make use of active substances shall be approved from IMO according to the procedure developed by the IMO. The Convention described that active substance means a substance or organism, including a virus or a fungus, that has a general or specific action on or against harmful aquatic organisms and pathogens. The Marine Environment Protection Committee of IMO gave basic approval to 13 ballast water management systems and final approval to 4 systems until October 2008. This paper considered the matter of procedure and documents of the basic and final approval based on the "Procedure for approval of ballast water management systems that make use of Active Substances (G9)" and "The Methodology for information gathering and the conduct of work of the GESAMP-BWWG" and summarized the specifications of the treatment systems which was granted the basic or final approval from IMO and raised several points.

The climate change has become one of the most important global issues that require global responses. As one of the leading contributions to climate change, greenhouse gas emissions and Ballast Water Management have attracted growing attention from the international community. The International Maritime Organization (IMO) received its mandate to regulate International Convention for the Control and Management of Ships' Ballast Water and Sediments in 2004. The convention requires that every vessel must be equipped Ballast Water Management System (BWMS) in 2017. Based on this situation, this study aims to analyze the present state and data from the exports of BWMS(HS842121). The results show that as the most leading country in the field, Germany has the largest market share (14.33%), Revealed Comparative Advantage (RCA) index 1.76, and Trade Specialization Index (TSI) 0.636 in the world. The two other leading countries such as Denmark and Netherlands follows the ability of Germany. The Korean market share of HS842121 shows market share (5.98%) which is a bit bellow high compared to other countries. However the RCA index (1.85) presents the state of comparative advantage. In addition, Korea's TSI index (0.453) indicates that it is in the state of export specialization. The Korean BWMS and Shipbuilding industry maintain the state of export specialization. They are also in the state of import specialty. For Korea to raise its export competitiveness and to ensure shipbuilding competitiveness, it is necessary to intensify supporting systems and related policies.
