Changes in ship design and construction mark advancement in the maritime industry. Also, continuous developments in regulatory efforts identify the need to manage and ensure the advancement in design parameters is a step forward - toward a future which remembers marine shipping's disastrous, historical events. The goal of this paper is to outline a method of quantifying marine shipping spill risk...
This paper presents a methodology for risk-informed maintenance and reinvestment decision support in distribution companies. The methodology incorporates different analyses such as simplified risk analyses, quantitative risk analyses and economic analyses, into a multi-criteria decision support framework. The goal of the methodology is to provide formal decision support for asset managers in distribution...
Due to large span across the region, the complex natural and social environment, inflammability and explosive of the transmission media, the safety management of long-distance natural gas pipeline is very difficult. In this paper, we adopt quantitative risk assessment method, base on GIS technology, network technology and database technology, then design the Natural Gas Pipeline Quantitative Risk...
Equipments and systems on board ship, although well designed, will not remain safe or reliable if they are not maintained. The general objective of the maintenance process is to make use of the knowledge of failures and accidents to achieve the maximum possible safety with the lowest possible cost. In this insight, this study proposes a risk-assessment methodology for preventive maintenance planning...
As the substitute of mechanical hydraulic governing system, steam turbine digital electro-hydraulic control system presents different maintenance characteristics. If the traditional maintenance strategy is still adopted, that is the replacement or inspection time determined just according to overhaul or minimal maintenance standard items, the result is either maintenance cost increasing due to excessive...
Advanced methods of well completion (e.g. horizontal drilling) and secondary recovery have the potential to extend our hydrocarbon resource base until alternatives can be brought onstream in the required quantities. Structural integrity management (SIM), also know as platform reassessment and rehabilitation, is a key to extending the useful life of offshore platforms which support these activities...
This paper presents a risk-based methodology to estimate optimal inspection & maintenance intervals which maximize a system's availability. The methodology is comprised of two steps: availability modeling, and risk-based inspection & maintenance calculations. The methodology is easy to apply, and needs readily available data. The approach can be further improved by including an updating scheme...
