In the global manufacturing industry, digital transformation is emerging as an important issue for companies to improve productivity and strengthen industrial competitiveness. The government and shipbuilding companies drive research and development to attain advanced technologies through digital transformation for shipbuilding & offshore plants, one of Korea's representative manufacturing industries. Therefore, the digital transformation of the shipbuilding & offshore plant industry was defined using an input-output analysis model, and the economic interrelationships of industries linked to the digital transformation of the shipbuilding & offshore plant industry were analyzed. According to the analysis, the shipbuilding & offshore plant industry ranks second among all 34 industries regarding the forward linkage effect. The backward linkage effect was ranked 27th, making it a mid-demand industry with a robust forward linkage effect. In addition, the production-induced effect was 0.455, the value-added-induced effect was 0.174, and the employment-induced effect was 1.779 people per billion won. The contribution of this study is that it will provide the basis for establishing policies necessary to strengthen the competitiveness of the shipbuilding & offshore plant industry. Also, it will help analyze the economic effects of digital transformation in other manufacturing industries.

Korea is worldwide top manufacturer of offshore plant industry, while shown weakness in high-valued offshore plant service industry (OPSI). The governmental support policies and studies for fostering programs are centered on shipbuilding and engineering sector. On the other hand, offshore logistics service sector among the programs is neither included as governmental fostering support sectors nor ever-studied. Domestic shipping and logistics companies have many experience of handling various project, heavy-lift cargo and even super blocks on shipbuilding industry. However they are faced with lack of appropriate heavy carrier and others. So for their successful entering into offshore plant logistics market, systematic preparation, studies and supporting policies are highly recommended.

When a plant owner requests plant 3D CAD models in the format that a shipbuilding company does not use, the shipyard manually re-models plant 3D CAD models according to the owner's requirement. Therefore, it is important to develop a technology to compare the re-modeled plant 3D CAD models with original ones and to quantitatively evaluate similarity between two models. In the previous study, we developed a graphic user interface (GUI)-based comparison system where a user evaluates similarity between original and re-modeled plant 3D CAD models for piping design at the level of unit. However, an offshore plant consists of thousands of units and thus a system which compares several plant 3D CAD models at unit-level without human intervention is necessary. For this, we developed a new batch model comparison system which automatically evaluates similarity of several unit-level plant 3D CAD models using an extensible markup language (XML) file storing file location and name data about a set of plant 3D CAD models. This paper suggests system configuration of a batch-mode-based comparison system and discusses its core functions. For the verification of the developed system, comparison experiments for offshore plant 3D piping CAD models using the system were performed. From the experiments, we confirmed that similarities for several plant 3D CAD models at unit-level were evaluated without human intervention.

This study analyzed the offshore plant industry and related regulations such as ISO, IEC, and Norsok Standards to develop an integrated network management system (INMS) capable of both on-site and remote management and configuration of IP-based network equipment in offshore plants. The INMS was designed based on actual specifications and POS plans, and a plan of management was verified through an offshore plant engineering company. Various modules such as PAGA interface modules, CCTV, IP-PBX, and HF-radio communication modules were developed for system implementation. Protocol and data design and screen design were followed by framework development and introduction of the automatic satellite communication function.

본 연구는 사회네트워크분석을 이용하여 전라남도 조선해양플랜트산업 제조업체의 구매 판매 네트워크 구조의 실태를 파악하였다. 그 분석결과는 다음과 같다. 전라남도 조선해양플랜트산업은 대부분 중 소기업들로 구성되어 있어서 대기업과의 하청관계로 인한 구매 판매 네트워크가 주를 이루고 있다. 특히 제품의 판매를 위한 거래에서는 대기업이 입지한 영남권의 제조업체로 거래가 집중되는 실태를 보이고 있다. 이러한 결과를 보면, 최근 조선산업의 위기에 직면하여, 영남권에 위치한 대기업의 구조조정은 그 기업들에 의존성이 큰 전라남도 조선해양플랜트산업에 타격이 클 것으로 예상된다. 따라서 전라남도 조선해양플랜트산업이 이러한 위기에 대응하기 위해서는 판매 거래를 위한 네트워크를 보다 다양하게 확보해야 하며, 이를 위해서는 지역 내 판매업체를 발굴하거나 육성하는 정책이 필요할 것이다.

Offshore plants is an intensive industry where real value is able to be created when EPCIC(Engineering, Procurement, Construction, Installation, Commissioning) is combined. Many universities and educational institutions have established major fields and graduate schools related in offshore construction and engineering as well as safety training and occupational courses. Most of the personnel who have graduated and passed those educational institutions have been working in domestic shipbuilding companies and marine equipment manufacturers. Therefore, customized education and training should be developed according to the educational demands required and then skilled personnel are needed to be supplied at proper times. This study, therefore, has found personnel demands inside and outside the country and occupational sections of offshore plants. Consequently, this study suggests making up a council comprised of shipbuilding companies, marine equipment manufacturers and educational institutions with government organization, and also researches the necessity of getting a job of personnel trained by the customized education. These results are expected to contribute to the development of education curriculum of domestic offshore plant as well as ODC(Offshore Development Center).

There are several existing studies for the weight estimation of offshore plants. However, most of them were applicable at the pre-FEED (Front End Engineering Design) stage. In this paper, a preliminary study on a method for the weight estimation and calculation of offshore EPC (Engineering Procurement Construction) projects is made for the use at the estimation stage after FEED. Based on literature surveys including ISO (International Organization for Standardization) 19901-5 about weight estimation, we proposes new weight factors and a weight curve. Weight factors defined in this study include MTO (Material Take-Off), estimated weight, FEED maturity factor, allowance factor, and contingency factor. The proposed method utilizes bottom-up approach for weight estimation and it can be used for the weight estimation and calculation of offshore EPC projects at the estimation stage.

The shipbuilding and offshore industry is a large and complex assembly industry, which causes many safety accidents. The major accidents in the shipbuilding and offshore industry workplaces are stenosis, falling objects, dust, fire, explosions, and gas poisoning. The accident by worker in this industry mainly has three factors: frequent movement, narrow work space, and increased use of subcontractors. To control these factors, it is necessary to monitor the worker's location and work status. In this paper, a worker location monitoring system using inaudible sound wave was designd that can be used in environments with many metal barriers. The process included deriving stakeholder requirements, transforming to system requirements, designing system architecture, and developing prototype. The prototype was validated by third-party testing agency. As a result, it satisfied the designed performance and verified its feasibility.

2007년 미국에서 시작된 글로벌 금융위기의 영향은 국내의 해운 조선 분야에도 크게 영향을 미쳤다. 이와 관련하여 국내 조선소는 해운경기 악화로 인한 상선 수주물량 감소의 대체수단으로 여러 방면에서 수주전략을 수립하였고, 선택한 분야가 해양플랜트였다. 그러나 국내 조선소는 해양플랜트 관련 계약이 갖고 있는 위험성 분석에 대한 대비 없이 단순한 매출액 확대와 일감확보를 위한 무리한 영업 수주전략을 추진하였다. 이러한 결과, 해양플랜트 발주자와 초기에 계약한 금액보다 많은 비용이 투입되거나 제조물 인도지연에 따른 지체상금을 지급해야 하는 법적인 문제로 확대되었다. 주요 법적분쟁의 원인은 해양플랜트공사 시 발생할 수 있는 비선형모델에 의한 위험성 분석, 공정관리의 미숙, 국내 조선소가 "Engineering Procurement Construction 일괄계약"을 사용하는 해양플랜트공사계약의 이해 부족에 기인한다. 특히, 위험성 관리 항목의 한 요소로써 계약상의 독소조항에 대한 충분한 검토가 이루어지지 않은 점에 있다. 이러한 계약서를 검토할 만한 인력도 부재하다. 따라서 이 연구에서는 계약목적물의 인도지연이 발생할 수 있는 구체적 위험성의 존재를 식별하고, 해양플랜트공사계약 상에는 어떠한 불공정조항이 존재하며, 그러한 불공정조항이 실제 양 당사자에게 어떻게 적용되는지를 국내 조선소의 프로젝트 관리자의 인터뷰와 선행연구를 참조하여 구체적 위험요소가 계약상으로 어떻게 함의되는가에 대해서 살펴보았다. 이를 통하여 해양플랜트공사계약상 제조물인도지연에 관한 계약당사자의 법적 책임관계와 국내 조선 해양플랜트 산업발전에 기여할 수 있는 개선방안을 도출하였다.
