Nowadays, vessel's size is tending to bigger, Therefore port facilities are developed according to this trend, which has been shown in the competition of Hub-Port among the main ports such as Port of Busan and Port of Shanghai. However there are the limited number of large containerships more specifically so 70% of the total ships calling at Busan Port are small and medium sized ships which are less than 20,000 ton As a result, it is necessary to consider the handling facilities of these ships which had been disregarded The big size of facilities increases handling cost bemuse of high investment so it is possible for small and medium sized ships to have disadvantages financially and avoid calling. In this paper, we estimate the propriety of utilization of crane and labor according to the size of vessels after analyzing time value cost, reflecting the size of vessels, size and number of crane and labor structure, and container handling cost value.

All the major ports around the world as well as those in Korea have been exploring their own strategies to survive rapidly changing marine transport environment worldwide. In particular, Busan New Port under development still fails to meet expected logistical traffic, although it operates 6 berths. That is why it is necessary to point out current challenges in logistical strategy of Busan New Port for fully dealing with logistical traffic. Therefore, this study can propose the following ways to facilitate logistical traffic of Busan New Port. First, it is necessary to apply equal tariff to incentives given to shipping agent under the associations between existing harbors and Busan New Port. Second, it is required to increase governmental subsidy for truck freight transport. Third, it is demanded to seek possible ways to transport export and import freight and thereby create independent logistical traffic. Fourth, it is necessary to contact shipping agents residing in new ports and establish a logistical program for shipping freights via Europe, Middle East and Russia as well as those by way of North America, Japan, Korea and China, ultimately making sustainable marketing strategy to create a series of continuous transshipment freight, not temporary one. Finally, it is advisable to operate networked logistical programs with small- or medium-sized overseas shipping agents in business association with large-scale overseas shipping agents.

The inefficient operation of Busan New Port is due to container-terminal operators being dispersed in small groups, rather than being integrated. This dispersion increased following the reorganization of global shipping alliances in 2016 and causes unnecessary Inter-terminal Transportation(ITT) and ship delays. Studies of integrated operations for larger container terminals show that integration is not going well, however, due to the pre-emptive task that follows the integrated operation. Therefore, in this study, we divided the integrated operation into stages based on a simulated model of the container terminals in Busan New Port. The simulation took into account future increases in the ship's enlargement and terminal congestion, and the operational effects of each type of integrated operation were analyzed and evaluated.

지속적으로 발생하는 대형 해양사고에 대한 대처방안의 일환으로 진행된 국제해사기구에서의 조사 및 연구는 선박의 물리적 감항성 이외에 선박을 운영하는 인적자원의 과실에 주목하게 되었다. 이러한 인적과실에 대한 대처방안으로 1994년에 '1974년 SOLAS 협약'의 부속서로 '국제안전관리규약'이라고 하는 이른바 'ISM Code'를 채택하게 되었다. 우리나라는 1999년에 'ISM Code'를 구 해상교통안전법(현 해사안전법)에 관련 조항을 신설하여 시행하고 있다. 최근 개정된 해사안전법에서는 해운선사가 선박의 안전운항 및 해양환경보호를 위한 안전관리체제를 수립하고, 이를 이행하기 위한 사업장의 인적 구성원들이 갖추어야 할 요건에 대해서 규정하고 있다. 하지만 법률 이행당사자인 선박소유자 또는 안전관리대행업자 등은 조문내용을 해석함에 있어 명확하고 통일된 의견을 내지 못하고 있어 혼란을 야기하고 있다. 이 논문에서는 해사안전법상 안전관리책임자와 안전관리자의 자격기준 등에 관한 법률상의 문제점을 살펴보고, 이에 대한 개선방안을 제시하고자 한다.

불과 3년 전까지 조용하고 한적한 농경지였던 고양 원흥지구. 서울 근교에 위치해 바쁜 삶에 지친 도시민들에게 잠시나마 여유로운 풍경을 선사해 주던 이곳이 최근 서민들의 안락한 보금자리로 변화하고 있다. 국내 내로라하는 대형건설사들이 모여 지역 곳곳에서 아파트 단지를 조성하고 있는 것이다. 헌데 그중에서도 우수한 안전관리로 남다른 유명세를 타고 있는 현장이 있다. 그곳은 바로 SK건설이 자연친화형 주거단지를 목표로 건설하고 있는 '고양 원흥 A6BL 아파트 건설공사 3공구 현장'이다. 이곳은 대지면적 7만 $3533m^2$에 지상 1층~10층/22층 규모 아파트 19개동 1,392세대를 조성하는 현장으로, 작업반경이 매우 넓고 하루 출력인원만 600여 명에 달한다. 그런데 이런 거대한 사업규모에도 불구하고 이곳은 지난 2011년 착공 이래 단 한 건의 사고도 없이 무재해 현장을 이어가고 있다. 어떻게 이곳이 우수한 안전현장의 반열에 올라섰는지, 직접 찾아가 그 비법을 살펴봤다.

Faced with global agenda of greenhouse abatement program including regulations and $CO_2$ emission trading scheme, shipping companies are enforced to a high level of efficiency in fuel consumption. Accordingly shipbuilding companies worldwide are required to develop fuel-efficient ships which otherwise traditionally consume a great amount of fossil fuels. In this dissertation, relevant to the improvement of fuel efficiency for commercial ships, design methodology through the numerical simulations are intensively described. This work consists of derivation of effective hydrodynamic design practice based on the application of longitudinal grooves to effectively improve the pressure distribution around ship hull. The primary objective of the present study is to improve ship resistance performance using longitudinal grooves which originate from long strips on the abdomen of humpback whale. Several groove shapes have been extensively investigated and the proposed shape efficiently controlled the variation of pressure distributions acting on the hull surface.

In recent years, the transportation sector has been undergoing very rapid and multifarious changes due to the M&A, alliances between shipping companies, introduction of larger container ship as it cost reduction measure and the application of integrated logistics to satisfy the needs of customers. Therefore, container terminal is required adequate terminal facilities, sufficient channel depth, efficient handling and low cost of port fees and dues. The purpose of this paper is for functional assessment of efficient container terminal. Firstly, the container operating process information about yard equipment and chassis is extracted through the analysis of practical daily work report of container terminal. Also, the formulae of skill factor and troubles of operator on transfer crane are defined. Lastly, container handling simulation model which consideration of skill factor and trouble of operator is proposed by Petri network model.

In recent years, the pileup of world ports is deepening as time goes by due to China effect and continuous increase of world trade volume. The shipping companies try to reduce their shipping cost by using mega vessels in the ports. Shipping companies consider most of the ships turnaround time as a critical factor when selecting a calling port for reducing cost. This paper will suggest how we can guarantee terminal QoS like ship waiting time ratio and ship residing time applying RFID(Radio Frequence IDentification) technology, raising up rapidly as a fundamental solution of new growing industry to port information system. Also, lead time of whole port logistics can be decreased for reduction of loading & discharging time and result from productivity improvement of Twin-lift G/C(Gantry Crane} as applying RFID technology to terminal operation. The purpose of this paper suggests that the new business model of U-Port which port QoS can be guaranteed using RFID based RTLS technology.

The purpose of this study is to forecast the ship-management market size and to propose a management improvement scheme to support Korean ship management companies in the stagnating world shipping market. Recently, global shipping companies have begun outsourcing all ship management activities. However, the Korean ship-management market represents just 3.75% of ocean shipping companies' sales, making it necessary to enlarge this market. This study performs a business analysis of ship management companies in Korea. The findings show that these companies' profitability and financial structures are not very good, mainly because of insufficient management ability and small firm sizes. Therefore, we propose that the Korean government supports crew training programs and shipping financial systems.

Strategic partnerships of alliances and large shipping companies have been steadily launched in shipping market. Converting these alliances into customers and maintaining them important hub port status. The cases of container terminals to establish a political strategy based on. On the other hand, bulk terminals are relatively unexplored container terminal and bulk terminal are included in the same category of port empirical research from the overall perspective. Therefore, analysis of structural equations was utilized in this study. Analysis of the entire measurement model showed that all items except "Results - Intention of renewal" on bulk terminals were significant. This study is expected to contribute to promotion of empirical studies in various levels by compare container terminals and bulk terminals.
