손명조(Myeong-Jo Son),김태완(Tae-wan Kim) (사)한국CDE학회 2014 한국 CAD/CAM 학회 학술발표회 논문집 Vol.2014 No.2
온실가스 감축과 청정에너지 개발로 인해 대체에너지 연구와 개발이 활발하게 진행되고 있고, 그 가운데 하나가 풍력에너지이다. 풍력에너지가 활발하게 개발되고 있는 유럽에서는 양질의 바람으로부터 안정적으로 발전을 할 수 있고, 소음 공해로부터 자유로운 해상풍력발전이 본격적으로 개발, 건설되고 있으며, 그 비중이 점차 증가할 것으로 전망되고 있다. 본 연구는 앞으로 조성될 국내 해상풍력발전을 위하여, 해상풍력발전 플랫폼의 이송과 설치 프로세스를 분석하고 시뮬레이션하고자 한다. 다양한 이송수단과 설치수단에 대한 개략 모델을 생성하고, 다양한 이송 및 설치 시나리오에 대해서 이산사건 시뮬레이션을 수행하여 일정계획과 비용분석을 그 결과로 제시하고자 한다. 이를 위한 기초연구로서, 해상풍력발전의 하부구조물로 가장 많이 사용되고 있는 모노파일 (Monopile)의 이송 및 설치 시뮬레이션을 구성하고 수행하였다.

The finite element modeling of a ship for hull structural analysis on the basis of new harmonized common structural rules (CSR-H) is to be extended to the cargo holds in fore and after body of a ship. Unlike the parallel middle-body where the external and internal features of hull are equal along to the longitudinal direction of a ship, in fore and after body, the external and internal features of hull vary linearly or even irregularly in forms of a surface or a curve along to the longitudinal direction of a ship. Thus, it needs lots of design man-hours for the modeling for structural analysis. In order to save man-hours in initial structural design phase of a ship, the specified 3D CAD system has been adopted in shipbuilding industry. Through the interface between CAD and CAE (rule scantling and direct strength assessment), design man-hour in initial design phase can be saved even under the environment of CSR-H.

As the part of IT convergence in the shipbuilding industries, we deal with the adoption of the business process management (BPM) to a ship hull production design process. A ship hull production design which is the processbased task requires most man-hours (M/H) amongst whole ship design processes and is coupled with a ship production directly so that it could contribute largely to a productivity enhancement. Thus, we analyzed the hull production design task in the perspective of the business process so that we generated the BPM models of a manager and a design engineer, respectively. Especially in a manager process, we have implemented optimal assignment method as a part of the decision support system that helps a manager to make an assignment of hull blocks to design engineers efficiently in the BPMS (BPM system). In this paper, we suggest the concept of the block standard design M/H and the variable design M/H of a design engineer for the production design optimal assignment method. According to this concept, we modeled a design engineer and a block and computed the estimated M/H using these models and their mutual interaction. To make the assignment that minimizes total required M/Hs in the production design, we adopted Hungarian Algorithm. The BPM executable model of the hull production design process has been implemented using the Bonita Open Solution 5.5 that is one of the representative open source BPMS.

For the reuse of the existing 3D block model of a ship, we analyze the hull modeling process using AVEVA marine which is a representative CAD (Computer-Aided Design) system for the shipbuilding. In the AVEVA marine environment where the design engineer makes 3D model on the 2D view that is so-called 2.5D, it cannot be possible to copy to reuse the block model just simply copying the 3D feature model itself like in the general mechanical CAD system or Smart Marine 3D which is based on the 3D model representation. In this paper, we analyze the Scheme file where the 3D model is defined in AVEVA marine so that we develop the program for the block copy and translation using this Scheme file. It is significant that this program can be immediately available as a real-world application on the AVEVA marine environment.

Shipbuilding industries has adopted the IT convergence to the shipbuilding as the new engine for growth. 3D CAD System and the enterprise IT such as the ERP, the PLM have been customized and built in the shipyards to increase the productivity. As the part of the IT convergence in the shipbuilding industries, we deal with the adoption of the business process management (BPM) to a ship hull production design process. A ship hull production design which is the process-based task requires most man-hours (M/H) amongst whole ship design processes and is coupled with a ship production directly so that it could contribute largely to a productivity enhancement. At first, we describe the concept of the BPM execution model that is the key condition to execute the developed processes in the BPMS. And, we explain a hull production design process and how to model this on the basis of a business process and how to implement as the BPM execution model. In addition, we suggest the benefits and expected improvements in a hull production design process by the BPM execution. The BPM executable model of the hull production design process has been implemented and executed using the Bonita Open Solution 5.5 that is one of the representative open source BPMS.
