摘要

船舶動力系統是一個相當複雜系統，它不僅是由各式各樣的系統所組合而成，且各個系統的組成如主要裝備之輔機系統或發電機系統，均由兩部或兩部以上組合而成，一般大都誤認為並聯系統，其實不然於船舶上所安裝的裝備其控制應屬於備便性的系統。由於船舶是遠離陸地的獨立系統，為達成船舶的各項任務，應保證各該系統能作較長時間的安全運轉。而動力系統為船舶推進系統主要的動力源，若此裝置失效或故障，將使船失去動力，不僅將使該船處於危險狀態，亦可能導致海損事故的發生。因此，船舶之動力系統，除經濟性外，尚應考量其安全性及可靠性，而影響其可靠性因素有很多，例如基本設計、製造標準、維修、低磨耗及提高缸套溫度以降低腐蝕等等。本文旨在介紹如何分別就並聯與備便兩方面作推演計算及運用可靠性理論來探討船舶動力系統的問題。

Power plant system for shipboard is a complex complete and independent system, the system consisting of marine propulsion power plant, essential service auxiliary machinery and diesel generator. Auxiliaries are always to comprise two or more independent and separate equipment and include their prime mover and controllers which are necessary for the safety of life and the safety or operation of the ship at sea. In general, the auxiliary system is considered to a parallel system, but it should be standby system. The marine propulsion power plant is very important system for propelling, the ship will be under danger condition when the system occurs trouble or damage. So, the system should be high reliability and efficiency. The reliability of the system is influenced by several factors, for example basic engine design, manufacturing standards, maintenance, keep down wear rates and raised linear temperature to avoid corrosion etc. In this paper, Author will calculate with two types of parallel and standby system and research the tactics of Power Plant System for Shipboard based on reliability.
