세계 최고 수준의 선박을 건조하여 매년 최우수 선박상을 수상하고, IT(정보가술)가 세계 최고 수준이라는 우리나라에서 선박을 설계$.$건조하는데 사용되는 각종 소프트웨어는 과연 세계 최고 수준인가？ 선박을 건조하는데 사용되고 있는 소프트웨어의 개발 주체는 크게 두 경우인데, 외국 제품이거나 조선소에서 독자 개발한 것이다. 외국 제품의 경우, 소프트웨어의 기술력과 안정성은 확보되어 있으나, 우리 조선소의 설계 개념이나 생산 시설에 적합하지 않은 경우가 많아 조선소가 독자적으로 변환하거나 외국 개발 주체에게 의뢰하여 수정 보완하고 있는 실정이다. 이 경우 비용과 시간 문제를 논외로 하더라도 우리의 설계와 생산 정보가 외국으로 유출될 수 있는 가능성이 매우 높다고 하겠다.

디지털 선박 건조에 관심이 높아짐에 따라 선박 내에 USN(Ubiquitous Senser Network)의 구축이 요구되며, 센서 노드와 서버의 응용 프로그램 사이에서 중간 역할을 담당하는 선박USN 미들웨어가 필요하다. 일반 USN 미들웨어와는 달리 선박USN 미들웨어는 선박이라는 특수환경을 고려하여 설계되어야 한다. 선박은 해상운송수단이므로, 보다 높은 안전성의 확보가 필요하고 제한된 자원의 공급으로 인해 효율적인 자원 관리가 필요하기 때문이다. 본 논문에서는 이러한 요소들을 고려한 선박USN 미들웨어를 설계한다. 설계한 USN 미들웨어는 상황인식을 통해 데이터의 거짓 유무를 판별하여 불필요한 데이터 전송을 차단하여 에너지 효율적인 특성을 갖는다.

2009년 초반 중국은 물량중심으로 조선분야 수주잔량 부분에서 한국을 추월하였으나, 현재 한국은 조선강국으로서의 위치를 고수하기 위해 IT조선 융합기술 개발을 통하여 디지털선박과 해양플랜트 등 고부가가치 선박 제품을 제조하고 있으며, 이러한 선박 제조 과정에서 에너지 및 인력 절감을 통해 고효율화, 안전성 제고 등 신뢰도 향상 또한 추진하고 있다. 최근 국내에 수주되고 있는 LNG선, 호화여객선, 석유시추선 등의 쉐이빙선과 같은 고부가가치 선박의 경우 국산화율이 60%가 채 되지 않는 현 상황에서 선박 관련 IT 기술 확보는 선박 건조 국산화 비율을 높이고 조선산업 수주 경쟁력을 높이는 중요한 관건이 될 것으로 예상한다. 본고에서는 세계 1위를 지키고 있는 조선산업의 질적성장을 위한 IT+조선 기술현황과 전망에 대해 기술한다.

Digital shipbuilding is a technology to reduce the total cost and lead time inevitably made by reschedule and rework in a shipyard. Strategic planning should be undertaken in order to have an effect on the applicable field. We aim at planning a strategy of digital shipbuilding technology by analysis of production planning workflow in this paper. In the basis of BPR methodology, the as-is business process is analyzed to build an workflow model, and derive the bottleneck business process. We dig into the inside details of the process to illustrate an diagram of the core improvement opportunities, and perform process simulation not only to create the application scenarios but also to expect the main effects. The application strategy will make a basic sketch to save both the production cost and time for high quality products in the shipyards.

In this paper, a point-to-multipoint wireless communication system based on Bluetooth specifications, which is possibly applied to very large vessels, is implemented and analyzed. Here, a communication network is composed of a slave Bluetooth module connected to the task computer and multiple master Bluetooth modules equipped with a sensor. And exploiting the point-to-multipoint data communication among the Bluetooth modules, a surveillance system that recognizes and controls a variety of emergency situations happened on a large vessel is implemented. It is, therefore, considered that the wireless communication system implemented in this paper is possibly exploited a basic technology for the digital shipbuilding of the next generation.

Recently a technology paradigm of ship has been changed to digital ship, IT shipbuilding convergenced technology development and Human training is very important, that is important role of making high valued shipbuilding industrial development. In this paper, we introduce IT shipbuilding convergenced education program for training human of special skill. A course of study is made of analyzing a survey of IT shipbuilding convergenced core technology in shipbuilding industry. we surveyed marine wireless communication technology, S/W solution for vessel, and CAN & SAN technology in IT filed, and ship-building design and vessel construction technology in shipbuilding field. we put in industry specialist in our education program because we have a gole of training the person are adapted immediately in shipbuilding industry.

Recently, the accidents on the sea have arisen due to the increase of the nautical traffic and the digitization of equipments for marine. Therefore, IMO(International Maritime Organization) have provided the recommendation of EMI and EMS for radio communication and equipments of marine from SOLAS convention at July 1st 2002. In this paper, we measured EMC environment on the Hanbada, which is Korea Maritime University training ship, for basic EMC environment of ship. The measuring point was Bridge and Engine Control Room of the ship, we measured at the test point that was set at random. Measured Band is from 30 MHz to 2 GHz, polarization measurement is processed both vertical and horizontal polarization. We analysed the results in consideration of permissible criteria.

World leading company and research centers have invested much cost and effort into a PLM and digital manufacturing field to obtain their own competitiveness. We have been trying to apply a digital manufacturing, especially simulation to ship production process as a part of PLM implementation for a shipyard. A shipbuilding production system and processes have a complexity and a peculiarity different from other kinds of production systems. So, new analysis and modeling methodology is required to implement digital shipyard. which is a digital manufacturing system for a shipbuilding company. This paper suggests an analysis and simulation modeling methodologies for an implementation of a digital shipyard. New methodologies such as a database-merged simulation, a distributed simulation, a modular simulation with a model library and a 3-tire simulation framework are developed.
