TL;DR: In this article, a fire pump adapted to force out the water, which is pumped from a water source, from a nozzle provided at the front end portion of a delivery hose, is provided in the vicinity of the nozzle.
Abstract: In a fire pump adapted to force out the water, which is pumped from a water source, from a nozzle provided at a front end portion of a delivery hose, a nozzle control unit 8 adapted to control the fire pump remotely is provided in the vicinity of the nozzle. The nozzle control unit 8 is connected to a body of the fire pump 1 by power source lines 33 . On the nozzle control unit 8 , a control instruction unit for instructing an operating mode of the pump 1 , and a numerical value display unit for displaying the operation condition of the fire pump are provided. The transmitting and receiving of an operation control signal and a condition display signal are done between the pump 1 and nozzle control unit 8 by power line communication via the power source lines 33 , whereby the operation condition of the pump 1 is feedback displayed in real time in response to a control operation of a nozzle operator.
TL;DR: In this article, the authors present a screening and comparison tool for fire and explosion assessment on floating production storage offloading (FPSO) installations and the incorporation of an expert system into the tool.
TL;DR: In this article, a system for controlling the pressure output of an engine-driven centrifugal fire pump includes a discharge pressure sensor mounted in the discharge line of the pump, and a governor varies the RPM of the engine in response to pressure changes detected by the sensor.
Abstract: A system for controlling the pressure output of an engine-driven centrifugal fire pump includes a discharge pressure sensor mounted in the discharge line of the pump. A governor varies the RPM of the engine in response to pressure changes detected by the discharge pressure sensor. An electronically controlled hydraulic relief valve responsive to the discharge pressure sensor operates simultaneously with the governor to provide improved pressure control in overpressure situations.
TL;DR: In this article, a systematic human error prediction is performed for designated tasks during operational procedures of the emergency fire pump since human error can be regarded as one of the major factors contributing accidents at sea.
Abstract: This paper aims to conduct a practical application for human reliability assessment during operating procedures of an emergency fire pump on-board ship. A systematic human error prediction is performed for designated tasks during operational procedures of the emergency fire pump since human error can be regarded as one of the major factors contributing accidents at sea. Hence, human reliability performance is evaluated to enhance fire safety management in operational level on-board ship. In the paper, marine-specific error producing conditions are adopted under fuzzy sets environment. To enhance consistency of research and minimise subjectivity during expert's judgement stage, the paper is supported with a dominance factor which is used to adjust the impact level of expert's judgments in the aggregation stage of the methodology. The outcomes of the paper provide valuable contributions to the safety managers and technical superintends to monitor fire safety management and crew reliability performance.
