Under the concept of global economy, the enterprises are assigning design and production environments around the world in different areas. In shipbuilding companies, a serious problem of information exchange emerges as companies use traditional hardware and very distinct softwares appropriate to their field of expertise. To overcome the decreased productivity due to the interruption of information, the concept of simultaneous engineering and concurrent design becomes very significant. In this article, the concept oj collaborative design based on internet environments is described. Especially, the core technologies to achieve collaborative design environments among shipbuilding companies, ship owners, ship classification societies, model basin, and consulting companies are adopted.

Under the concept of the global economy, the enterprises are assigning design and production environments around the world in various areas. In shipbuilding companies, a serious problem of information exchange has emerged as companies use traditional hardware and very distinct softwares that is tailored to their field of expertise. To overcome the decreased productivity resulting from the interruption of information, the concepts of simultaneous engineering and concurrent design become very significant. In this article, the concept of collaborative design based on Internet environments is described. Specifically, the core technologies necessary to achieve collaborative design environments among shipbuilding companies, ship owners, ship classification societies, model basin, and consulting companies are adopted.

In recent years, attention of ship owners for the energy saving of the vessel is being collected due to the volume decline. Ship accommodation consists of watertight type windows and is closed, Ship HVAC is used to promote a comfortable environment for the crew. In addition requirements for comfort of the crew is getting stronger with the improvement of living standards, there is a need for HVAC improvements. In this paper, propose method to save energy and improve HVAC controls by using the HVAC structure of the variable air volume.

With the terrorist attacks on 11 September 2001, the ships and their crew' 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 of merchant ship are analyzed with a discussion in depth of the concept and principles of maritime security management. And then, ship's security model and security system to reduce security rish and to minimize damage are proposed.

Shipping companies have become interested in the development of strategic ship assets management systems which are implemented for high competitiveness and business rationalization to meet the tough business environment of high oil prices and decrease in cargo. In this paper we introduce a ship assets management system that is suitable for the SAN(Ship Area Network) environment. This system is designed to execute business strategy of ship owners giving consideration to requirements of shipping stakeholders. In addition we have implemented it in a web-based ERP system (SHERP) which separates user interface and business logic. The SHERP is based on STEP and PLIB, which are international standards for data exchange of mechanical devices and parts. It also adopts a ship ontology to manage the ship information and knowledge during its life-cycle. The SHERP will be a concrete example of servitization of shipbuilding, as an information system which is used in ships and ship groups.

Concerning $CO_2$ reduction from International Societies, lots of laboratories and relevant societies suggest many reports on how to reduce fuel consumption from their specific ways. Undoubtedly, cutting costs is the final desired destination for owner outcome, but many questions there are on the way yet: how is this measure working? how efficient is it? On what size of ship would it work best and be the most effective? etc. Fuel cost is one of the major cost elements for ship owners and/or operators. And by reducing fuel consumption owners and/or operators will reduce both their costs and the environmental impact from their ship. This paper is aim to address how the measures work for saving fuel consumption through improve propulsion efficiency, installation cost and benefit can be calculated easily in the return on investment for estimated one year operation, and finally their compatibility with other fuel saving measure devices.

Stabilizing the operation of dual fuel diesel engines is very important. The shipbuilding industry is rapidly growing, but gear components requiring reliability are still imported from other countries. The reasoning for this is three-fold. Firstly, it is compulsory that all ships must use devices that meet the performance standards specified in the Safety of Life at Sea (SOLAS) and the convention of MARine POLlution (MAPOL) to prevent pollution caused by ships. Secondly, most ships must comply with the ship classifications specified by ship owners. Therefore, it is specified that key engine gear components must be inspected and authorized for the quality and performance specified by the Ship Register Authority. Thirdly, it is essential that devices (engine gear) for human safety in ships comply with quality standards specified in the regulations and rules by the government. The Ship Register Authority's strict quality standards and approval requirements contribute to the reduction of motivation towards new investment and technology development by device component manufacturers. Therefore, this study aims to develop a method for using infrared thermography to examine gear reliability in order to ensure gear component reliability and national competitiveness in the global market.

According to the statistics of marine accidents occurring in Korea since the past 10 years, the proportion of small fishing boats having a gross tonnage of less than 10 tons was confirmed to be as high as 47.51% of the total marine accidents. Additionally, the trend of marine accidents involving small fishing boats has been increasing steeply compared with that of other ship types/sizes (gross tonnage); hence, countermeasures must be prepared urgently. The Korea maritime transportation authority proposed the introduction of a self inspection system to improve the ship inspection system of small fishing vessels. Futhermore the Ministry of Oceans and Fisheries recently prepared and implemented the 'Remote Method of Vessel Inspection Guidelines' to introduce non-face-to-face inspection methods. In this study, a self inspection approval system was presented as a method for reducing marine accidents of small fishing vessels. Moreover, a mobile application was developed to prepare a standardized remote method, and its effectiveness was analyzed. Resultantly, the necessity of introducing a mobile application-based ship inspection system was confirmed with the introduction of a self inspection approval system that could induce voluntary safety management in fishing vessel owners. Additionally, we confirmed that the self inspection approval system could effectively reduce marine accidents by raising the safety awareness of ship owners.
