Abstract

The dimensioning accidental loads have been selected through suitable quantitative risk assessment and generally utilized important factors for offshore facility design. The fire hazard can be quantified with dimensioning fire loads. The main purposes of fire protection are to maintain the functionality of safety systems within evacuation period and to prevent the escalation from initial fire to uncontrolled catastrophic fire. This paper introduces the applications and the design methods of active and passive fire protections as representative measures of fire protection of offshore facilities. The passive fire protection requires the high initial installation cost and much difficulty on the operation of facilities and their maintenance. The oil major clients have asked the design contractors of offshore facilities to optimize the amount of passive fire protection with relevant engineering technology recently.

해양플랜트의 설계는 위험요인을 정량적 위험성평가를 통해 계량화하여 그 결과를 설계에 반영하는 것이 일반화되어 있다. 대표적인 위험요소인 화재 위험에 대해서도 이는 마찬가지다. 계량화된 화재 위험에 대해 작업자들이 탈출하는 동안 안전설비의 기능을 유지하고 발생된 화재가 더 크게 전이(escalation)되는 것을 방지하는 것이 방화대책의 궁극적인 목적이다. 본 논문에서는 대표적인 방화대책인 능동방화대책과 수동방화대책의 적용사례를 살펴보고 수동방화대책의 설계기법들을 소개한다. 수동방화대책은 효과적인 방화기법이지만 초기 투자비가 많이 소요되고 운용과 유지보수에 애로사항이 크다. 따라서, 최근 들어 발주자들은 수동방화대책을 최적화하도록 해양플랜트 설계자에게 요청하는 추세이다.
