  • Chapter 11 – Reliability
    Firewater Pumps at Industrial Facilities, 2011
    Co-Authors: Dennis P. Nolan
    Abstract:

    Publisher Summary This chapter focuses on the mechanical and electrical reliability of the Firewater pumping System. One of the prime features that influences the reliability of mechanical and electrical devices is adequate and timely maintenance and service. Firewater pumps must start instantly after a period of standing idle and must deliver the required Firewater flows and pressures for the specified duration of the emergency. The reliability of the Firewater pump can therefore be established by examining the failure rates of its various components and its redundant features. The basic need for a reliable Firewater System is primarily economic and it must be determined by the industrial facility whether the Firewater System has adequate reliability to reduce economic losses due to potential fires. The Firewater System should be reliable enough to such an extent that during an incident it is not itself affected by the incident.

  • Special Locations, Facilities, and Equipment
    Handbook of Fire and Explosion Protection Engineering Principles, 2011
    Co-Authors: Dennis P. Nolan
    Abstract:

    This chapter briefly describes the special locations, facilities, and equipment. Process facilities are found practically everywhere and in diverse environmental constitutions. These environmental facets are different and remote that unique situations develop and that require specialized requirements for fire and explosion protection considerations. Arctic environments pose different ambient conditions than normally encountered at most process facilities. Along with this, a desert environment also poses different ambient conditions than normally encountered at most process facilities. The most obvious is that the ambient temperature level can reach extremely high levels. Tropical environments have unique ambient effects, which have to be considered for process facilities and the installed equipment. Heavy rains (monsoons, hurricanes, typhoons, etc.), animal or insect infestations, and direct sunlight exposures are the most common concerns for Firewater System components located in tropical locations. Heavy rains can produce flooding conditions that may envelop a Firewater pump location, especially if it is taking suction from a river source, without flood control measures. Offshore facilities pose critical questions regarding personnel evacuation and the possibility of total asset destruction if prudent risk assessments are not performed. In addition, many more facilities such as loading facility and oil filled transformers are discussed.

  • Chapter 2 – Philosophy of Protection
    Fire Fighting Pumping Systems at Industrial Facilities, 1998
    Co-Authors: Dennis P. Nolan
    Abstract:

    Publisher Summary The chapter presents the philosophy of protection comprising protection options, control measures, passive and active Systems, insurance requirements, and internal company policy and standards. Remote, noncritical, or low-value facilities may not require a Firewater System because the cost to protect these facilities outweighs their value to the organization. The primary process emergency control methods are by process controls, isolation, and depressurization. One avenue of protection for a facility is to allow a fire incident to resolve by allowing the fire to consume the fuel available to it. National or local codes may also require the installation of fire protection devices, which are usually a combination of passive and active Systems. Provision of an adequate Firewater System usually rates as a high percentage in the risk assessment for any facility. Municipal insurance grading schedules have historically placed approximately 35 percent of their allowable deficiency rating points on an adequate Firewater supply and distribution System during grading of insurance levels for a community. Most companies have their own internal management policies and engineering standards or guidelines for the design and construction of their facilities. These documents may be extensive and defined if and when a fire pump is required, installation and arrangements, Firewater supplies, durations and types of pumps and drivers allowed or they may be relatively simple and basically require the installation meet local fire codes.

  • Chapter 11 – Reliability
    Fire Fighting Pumping Systems at Industrial Facilities, 1998
    Co-Authors: Dennis P. Nolan
    Abstract:

    Publisher Summary This chapter deals with mechanical and electrical reliability of the Firewater pumping System. Reliability is the probability that an item is able to perform a required function under stated conditions for a stated period of time or for a stated demand. The reliability of the Firewater pump can be established by examining the failure rates of its various components of Firewater pump System and its redundant features. One of the prime features that influences the reliability of mechanical and electrical devices is the performance of adequate and timely maintenance and service. The basic need for a reliable Firewater System is primarily economic. Failures associated with equipment can be categorized into two broad areas: generic failures or specific operating circumstances. A Fault Tree is a risk analysis method that describes the way a plant hazard or other undesirable event may occur in terms of combinations of individual nonhazardous component or operator failures. If a single part or point in the System will affect the entire operation, it is considered a single point failure (SPF) for the process. The minimum number of Firewater pumps provided for an industrial facility is usually two, a main pump and a backup pump for failure of the main pump to operate. Pumps require regular running to ensure operability. The primary concern in the reliability of a Firewater System during an incident is that it is not affected by the incident.

  • Firewater System inadvertent actuation frequency
    EG & G Idaho, 1991
    Co-Authors: Schroeder J.a., Eide S.a.
    Abstract:

    The purpose of this analysis was to determine generic and plant-specific Firewater inadvertent actuation frequencies for wetpipe and preaction Firewater Systems at the Advanced Test Reactor (ATR). Firewater Systems of both kinds are installed throughout the ATR facility. When installed for the protection of reactor equipment, Firewater Systems may also adversely affect the equipment they are meant to protect. This occurs when inadvertent actuation of a Firewater System causes wetting and subsequent damage to equipment
