Recently, the navigation risk is increasing significantly with growing of vessels' volume and propelling marine facilities, water bridges and port development etc. As a result, Ministry of Land, Transport and Maritime Affairs enacted a new law called MSA(Maritime Safety Audit) as a comprehensive maritime traffic safety management scheme in order to ensure safety improvements from the early planning stage to post managing of the development which affect the maritime traffic environment. MSA as a tool for improving maritime traffic safety is a formal safety diagnosis assessment in the existing or future ship's fairway by an independent audit institute. It examines the potential hazards of maritime traffic safety about the port development, if necessary, and is to ensure the implementation of appropriate safety measures. The primary purpose of MSA is to identify potential risk elements affecting safe navigation. This paper is aimed to introduce the backgrounds, the necessity and efficiency of MSA and also to describe some technical standards and diagnostic procedures.

The Maritime Traffic Safety Audit Scheme was institutionalized in 2009 to provide for professional surveys, measurement and the evaluation of navigational hazards that might occur in coastal waters in the course of marine work. Related researches that dealt with the reform of the Maritime Traffic Safety Audit Scheme found that there were no rules or regulations for verifying whether marine work conformed to audit results and reviewing the exactitude of ship handling simulations which were a crucial part of the scheme. According to the necessity of adopting an ex post facto management system in the field of maritime traffic, this study analyzed the similar audit acts such as the Natural Environment Impact Audit Scheme and the Road Traffic Safety Audit Scheme, and proposed specific articles for revising Maritime Safety Act in order to break out from the institutional inertia of the current Maritime Traffic Safety Audit Scheme. It is expected that a newly proposed legal system for verifying the performance of audit results and the exactitude of audits will help improve maritime traffic safety by eradicating potentially hidden hazards related to marine work.

The Maritime Traffic Safety Law of P. R. China has not the legal nature of navigation rule which regulates the vessel traffic directly but has the legal nature of management to ensure the safety and good order of the whale marine traffic. For that reason, the legal status of this Law is a general basic norm for the marine safety regulations rather than a definite enforcement regulation. This Law does not have any clear statements on adaptation of the steering and sailing rules of the International Regulations for Preventing Collisions at Sea, but it can be presumed the Convention would be applied on the viewpoint of the international practice. The subject matter of this Law is easily understandable, because the IMO and shipping countries have already made similar legislation. Since the maritime traffic condition of the P. R. China also has a direct effect upon the Korean coastal waters, it is essential to observe closely the process of enforcement and development of the P. R. China's Maritime Traffic Safety Law.

We carried out the maritime safety audit for Sandal Water Bridge constructed between Geje-Do and Sandal-Do in 2015. To study as to whether can be secured the marine traffic safety for this area, this research investigated and performed the marine accident, marine traffic volume, the marine traffic flow simulation and shiphandling simulation. It is considered to be required the quantitative guidelines for maritime safety audit including audit target area and formal audit object etc.

The Korean government has introduced and enforced maritime traffic safety assessment to secure traffic safety since 2010. The maritime traffic safety assessment is needed by law to design a new port or modify an existing one. According to Korea Maritime Safety Act, in the assessment the propriety of marine traffic system consists of the safety of channel transit and berthing/unberthing maneuver, safety of mooring, and safety of marine traffic flow. The safety of channel transit and berthing/unberthing maneuver can be evaluated only by ship-handling simulation. The ship-handling simulation is carried out by sea pilots working with the port concerned. The vessel's proximity measure is an important factor to evaluate traffic safety. The proximity measure is composed of vessel's closest distance to channel boundary and probability of grounding/collision. What is more, the probability of grounding becomes important. According to central limit theorem, a sample has a normal distribution on condition that its size is more than 30. However, more than 30 simulation runs bring about the increase of assessment period and difficulty of employing sea pilots. Therefore this paper is to find out minimum sample size for evaluating vessel's proximity. First sample sets of size of 3, 5, 7, 9 etc. are selected randomly on the basis of normal distribution. And then KS test for goodness of fit and t-test for confidence interval are applied to each sample set. Finally this paper decides the minimum sample size. As a result this paper suggests the minimum sample size of 5, that is, the simulation of more than five times.

This paper studied safety benefit of operation-effectiveness analysis on marine traffic safety facilities. In the operation-effectiveness of marine traffic safety facilities the benefits can be divided as safety benefit, transport benefit, and other benefit. Safety benefit was produced as the loss aversion cost of marine traffic caused by the reduction of marine accidents after establishing and operating marine traffic safety facilities. First of all the reduction rate marine accidents was estimated to do it, and the detail model of loss aversion cost was constructed Then each variable in the model was defined and the method of computation presented.

While the vessel become bigger and high speed, navigational passages become narrow due to an enlargement of all sorts of new ports, sea-crossing bridges and anchorages, leading to the high probability of marine accidents. Furthermore, a constant increase in the maritime transportation and the traffic volume on the sea led to a variety of sea traffic environments and it is a trend for the demand for the sea transportation environment to increase steadily. At this point of time, the Ministry of Land, Transport, and Maritime Affairs introduced the Korea Maritime Safety Laws evaluating the degree that The Safety Audit System for maritime transport, which evaluates the degree that all kinds of port facilities installed temporarily or installed into navigational passages, and the installations and repair constructions of S.O.C. facilities affect ships' traffic safety, was introduced through Korea Maritime Safety Laws and went into effect from November 28th, 2009. This study was performed to introduce an outline including the concept and purpose of the Maritime Safety Audit(MSA) system for maritime transport and the technological guidelines for scientific and standardized enforcement, thereby analyzing the system.

The recent increase in size and speed of ships resulted in the existing maritime routes becoming narrow relative to the size of new ships. At the same time, as the improvement and optimization in marine transportation take place and the construction of structures in seas and harbor improvements pick up speed, there is an increasing probability of marine accidents. Due to these environmental changes, the need to professionally analyze the effect of marine structures on navigation arose to ensure safety of ships and a law was enacted and introduced for the Maritime Traffic Safety Audit (MTSA). In this study, a Qualitative assessment for verifying the effectiveness of MTSA was carried out with case analysis and analysis model in other similar audit scheme. It is expected that an analyzed result for effectiveness of MTSA will be a steppingstone for enhancing the MTSA and keeping maritime traffic safety as its own purpose.
