This paper presents the robust design of each component used in the development of an induction bolt heating system for dismantling the high-temperature high-pressure casing heating bolts of turbines in power plants. The induction bolt heating system comprises seven assemblies, namely AC breaker, AC filter, inverter, transformer, work coil, cable, and CT/PT. For each of these assemblies, the various failure modes are identified by the failure mode and effects analysis (FMEA) method, and the causes and effects of these failure modes are presented. In addition, the risk priority numbers are deduced for the individual parts. To ensure robust design, the insulated-gate bipolar transistor (IGBT), switched-mode power supply (SMPS), C/T (adjusting current), capacitor, and coupling are selected. The IGBT is changed to a field-effect transistor (FET) to enhance the voltage applied to the induction heating system, and a dual-safety device is added to the SMPS. For C/T (adjusting current), the turns ratio is adjusted to ensure an appropriate amount of induced current. The capacitor is replaced by a product with heat resistance and durability; further, coupling with a water-resistant structure is improved such that the connecting parts are not easily destroyed. The ground connection is chosen for management priority.

본 연구에서는 국내 석유화학산업에 설치 운영 중인 DCS (Distributed Control System)에 설정되어 실제 운전에 적용하고 있는 PV high trip point에 설정된 alarm의 우선순위를 ISA 18.2 국제규격 또는 EEMUA 191 guideline 에서 제시하고 있는 기준과 비교 분석하여 현재 사용 중인 공정 alarm의 우선순위 관리상태를 확인하는 것이 목적이다. 공정 문제 발생 시 과도하게 설정된 high alarm이 짧은 시간 안에 운전자에게 제공되어 최우선으로 처리해야 할 alarm을 분별하기 어려워지는 상황이 발생하게 된다. 이로 인하여 운전자가 정해진 시간 안에 적절한 조치를 진행하지 못할 가능성이 커지고 예상하지 못한 공정의 shutdown이나 공정사고로 이어지는 사례가 다수 보고되었다. 그리하여 본연구에서는 alarm 관리에 관련된 국제규격을 소개하고 국내 석유화학산업 현장에 사용하고 있는 alarm 관리 수준을 확인하여 향후 국가 산단의 석유화학 공정에 발생할 수 있는 잠재적 위험을 알리고 위험 요소를 감소시킬 방안을 제시하고자 한다.

The Port of Pyeong Taek is located on the west coast, meaning that the difference between the rise and fall of tide is great (flood tide 1.8 to 2.9 knots, ebb tide 1.6 to 2.9 knots). Due to mainly N~NW'ly strong winds & high waves during winter, navigating as well as loading & discharging vessels must focus on cargo handling. The strong tidal and wind forces in the Port of Pyeong Taek can push an LNG carrier away from its berth, which will end up causing forced disconnection between the vessel's cargo line and shore-side loading arm. The primary consequence of this disconnection will be LNG leakage, which will lead to tremendous physical damage to the hull and shore-side equipment. In this study, the 125K LNG Moss Type ship docked at No. 1 Pier of the Pyeong Taek is observed, and the tension of the mooring line during cargo handling is calculated using a combination of wind and waves to determine effective mooring line and mooring line priority management. As a result if the wind direction is $90^{\circ}$ to the left and right of the bow, it was found that line monitoring should be performed bearing special attention to the Fore Spring Line, Fore Breast Line, and Aft Spring Line.

Unlike research focused on existing technologies and individual errors to analyze the causes of incidents, this study approached them from an organization and culture. And this study is not a one way study but cyclical study what can track cause down using causal loop diagram methodology. Four diagnostic criteria for the negative state of the safety culture : secretive, blame, failure to learning, and incremental learning, combine literature study and expert opinion to derive 41 variables. Connecting these variable make 4 causal loop diagrams and total causal loop diagram. Case accumulation in secretive, accident report in blame, knowledge accumulation in failure to learning, near miss discovery in incremental learning are the main variables. Safety incident is the objective variable by classifying them into 4 stages in total loop, leading track as the most affect is case accumulation, and Step 4 as you can see accident report and near miss discovery are the result of tracking down the cause. This study can be used as a basis for improving the management priority and the system in incident prevention.
