해운업의 성장과 더불어 국내 선박관리업의 시장도 급격히 확대되어 이제 과거의 인력송출이라는 단순한 업무에서 벗어나 선주재산의 관리라는 측면에서 기업다운 기업으로 성장하도록 새롭게 조명해야 할 단계에 이르게 되었고, 그 대상도 국내를 벗어나 국제시장을 대상으로 글로벌화하지 않으면 안 되는 단계가 되었다. 이 논문에서는 우리나라의 선박관리업의 성장에 지대한 영향을 미친 일본이 선박관리업에서 국제적 수준의 독립선박관리회사를 보유할 수 없었던 이유를 분석해 보고, 일본에 있어서 선박관리업의 쇠퇴과정을 모델링하며, 이러한 일본의 쇠퇴모델을 따르지 않고 발전하기 위한 한국의 발전모델을 제시하고, 제시된 발전모델로 전환하기 위한 방안을 제시한다.

With the terrorist attacks on 11 September 2001, the ships and their crews' safety and security have become a major issue in the maritime industries. In high-risk terrorism. not only ship owners and port authorities but also crew members on board should take precautions in the conduct of their business. In this paper, the vulnerability and essential elements in overall security of merchant ship are analyzed with a discussion in depth of the concept and principles of maritime security management. Author proposes ship's security model to reduce security risk and to minimize damage as a basic study for designing security system for merchant ship.

Ship owners are demanding quieter vessels since crews have become more sensitive to their acoustic environment. Accordingly, designers of shipyards need to respond intelligently to the challenging requirements of delivering a quiet vessel. In early design stage, to predict shipboard noise the statistical approach is preferred to other methods because of simplicity. However, since the noise characteristics of the ships vary continuously with the environments, it is necessary to update the prediction formula with data base management system. This paper describes the feature of database program with the prediction method. Database management programs with GUI, are applied to Intranet system that is accessible by any users. Statistical approach to the prediction of A-weighted noise level in ship cabins, based on multiple regression analysis, is conducted. The noise levels in ship cabins are mainly affected by the parameters of the deadweight, the type of ship, the relative location of engines and cabins, the type of deckhouse, etc. As a result of verification, the formulas ensure the accuracy of 3 ㏈ in 83 % of cabins.

As part of a structural health monitoring system, the relative geometric relationship between a ship and bridge has been recognized as important for bridge authorities and ship owners to avoid ship-bridge collision. This study proposes a novel computer vision method for the real-time geometric parameter identification of moving ships based on a single shot multibox detector (SSD) by using transfer learning techniques and monocular vision. The identification framework consists of ship detection (coarse scale) and geometric parameter calculation (fine scale) modules. For the ship detection, the SSD, which is a deep learning algorithm, was employed and fine-tuned by ship image samples downloaded from the Internet to obtain the rectangle regions of interest in the coarse scale. Subsequently, for the geometric parameter calculation, an accurate ship contour is created using morphological operations within the saturation channel in hue, saturation, and value color space. Furthermore, a local coordinate system was constructed using projective geometry transformation to calculate the geometric parameters of ships, such as width, length, height, localization, and velocity. The application of the proposed method to in situ video images, obtained from cameras set on the girder of the Wuhan Yangtze River Bridge above the shipping channel, confirmed the efficiency, accuracy, and effectiveness of the proposed method.

The routes of coastal passenger ships are important in the light of both economic and social view point. Islands around the Korean peninsular can be actually dominated by linking them with land by the ships. The service quality of the route is not high enough to satisfy habitants in the islands. The income of the service-users is increasing so that they expect better service in terms of ship's speed and cabin. The reality is not, however, good to motivate ship-owners to replace aged ships with new and large ones. The situation is caused by low passenger-fare and inefficient management. Therefore the fare should be raised and the fare system should be innovated. And the number of passenger ship companies should be reduced from 42 to 20 by merger and acquisition.

A lot of studies of ship's economy are on the traditional fields such asreducing propulsion resistance, raising cargo handling rates and lessening building consts, but there are few researches on the merchant ship's economy concerning their deadweights and speeds according to shipping companies managerial cercumstances. Contrary to the contemporary trend that "the bigger, the better, if the cargo handling rate could increased sufficiently to hold down port time to that rate of smmaler vessels", this paper demonstrates the existence of certain limits in ship's size and speed according to the coditions of the freight rates, voyage distances, cargo handing rates, prices of fuel oil, interst rates etc. Fom the curves of criteria contour for various ship's deadweights and speeds which are depicted from the gird search method, one can get the costs and the yearly profit rates under the conditiions of large volume with long term contracts for the transportation of bulk cargoes. In estimating ship's transportation economy, the auther takes the position that the profit rate method is properer than the cost method, and introduces the calculation table of the voyage profit rate index. The use of the criteria contours will be of help to ship owners in determining the size and speed of the ship which will be built or purchased and serve in a certain trade route.

Korea Shipping Act admits shipping conferences' joint actions like rate agreement, sailing agreement in some degree for development of shipping transport industries for decades. Meanwhile, EU has prohibited all kinds of shipping conferences' joint actions since October 2008, and many advanced countries also have similar position on shipping conference. The balance development between shippers and ship owners is very important in terms of national economic growth. So it is appropriate time to revise related laws such as Shipping Act and Monopoly Regulation and Fair Trade Act. First, It is direction for revision of Korean Shipping Act. The act has to define precisely the criteria of "unfairness" in case of admitting of shipping conferences' joint actions. Shipping conferences have a conference with shipper or shipper's delegation substantially on freight and transport conditions and so on. Second, It is direction for revision of Monopoly Regulation and Fair Trade Act. The fair trade commission has to perform fair roles between shippers and ship owners. The judgement of fairness has to confirm according to the spirit of not Korea Shipping Act but Korea Monopoly Regulation and Fair Trade Act itself.

On payment of the insurance money the insurer is entitled to be subrogated to all right and remedies of the assured in respect of the interest insured in so far as he has indemnified the insured. The purpose of subrogation is to prevent the assured from recovering more than once for the same loss, e.g. where goods are lost owing to a collision, the assured cannot claim the insurance money from the insurer and then sue the owners of the ship that negligently caused the collision. Under the doctrine of subrogation the right to sue owners of the negligent ship passes from the assured to the insurer on payment of the insurance money. The insurer is subrogated to the assured 'rights against the carrier under the contract of carriage. To defeat the cargo underwriters' subrogation righters, the carriers inserted in their B/L a clause allowing the carriers to have the "benefit of the shipper's insurance. But, in the Hague Rules, Hamburg Rules, Rotterdam Rules, its makes void any clause that assigns a benefit of insurance of the goods in favour of the carrier. In practice the insurer asks the assured to sign a letter of subrogation and retains the documents in order to prosecute the rights subrogated to him.
