Neptune Fire Protection Engineering LLC provides specialized services for the design of fire protection systems including firewater distribution network systems. We are proud to offer these services for a variety of industries including commercial, residential, military, governmental, industrial, petrochemical facilities including LNG and LPG gas processing facilities, and many more.
Our knowledgeable staff of experts begin by evaluating each facility to identify any special requirements or existing facility conditions that may pose a challenge to the implementation of the firewater system design. Firewater distribution systems are designed with consideration to existing facility conditions and include the specification of firewater pipe routing and size, fire pump system design, firewater storage tank design (where necessary), as well as the design of the individual fire suppression systems and components including, but not limited to, hydrant and monitor locations, foam and deluge systems, and nozzle and sprinkler layouts for the protection of fixed equipment and manual firefighting activities.
Design services range from conceptual level specifications to the complete detailed design of a system including material specifications, hydraulic modeling/surge calculations, and installation details. Additional services for construction administration (CA) may be provided as well. These CA services often include:
Design criteria for each system is prepared in accordance with all applicable codes and standards including National Fire Protection Association (NFPA) codes and standards, local building code and fire protection code requirements, insurance requirements (where applicable), as well as in accordance with industry best practices. The design criteria prepared for each project is developed to provide the optimum fire protection system design which is code compliant, practical and “constructible” for the specific facility, and is a design that will provide the best safety and protection for personnel and property. In addition, many members of the Neptune Engineering staff complete specialized fire fighter/first responder training that allows our team to incorporate an emergency response and firefighting perspective into our system designs.
The core of all firewater systems is the water supply network. When designing these systems, we account for the proper distribution and adequate hydraulic flows throughout the facility. We design each system using cutting-edge hydraulic modeling software to ensure adequate water flow and pressure in each point of the network is sufficient for the required firewater demand. Our staff has experience with hydraulic modeling software including SprinkCAD, PipeNet, AutoSPRINK, and AFT Fathom.
Neptune’s technical staff of fire protection engineers and designers always strive to design firewater systems that are simple and do not require fire pumps or other mechanical components whenever possible. However, when fire pumps are requires based on firewater demand and available water supply pressure, our designs include the necessary calculations and specification to determine the proper sizing and adequate type of fire pumps in order to meet the firewater demand and code requirements for each specific project. This includes diesel and electric pumps, N + 1 designs for redundancy, electrical power reliability analysis, and specification of fire pump locations for a variety of water sources including wells, surface water, municipal water, and tank supplies.
Oftentimes when projects are in remote locations with a limited water supply, a firewater storage tank is required to provide water for the facility. Neptune Fire Protection sizes firewater storage tanks based on an analysis of the firewater demand requirements and specifies the tank size, pipe sizing to and from the tank, as well as refill rates as required by code.
Beyond the water supply and distribution network, firewater systems are designed for the specified protection requirements such as fire suppression or cooling water. These designs are based on a number of factors including, but not limited to, the following:
Fire suppression systems include fire sprinkler systems, fixed and semi-fixed tank systems with and without foam, tank cooling water systems, and draft curtain systems, as well as systems engineered using a performance based-design for special scenarios.
Neptune’s engineering staff and sprinkler designer team have extensive experience in preparing not only fire sprinkler design, but also the design of numerous other suppression systems including aircraft hangar suppression (high-expansion and low-expansion foam), tank suppression and cooling systems, and draft curtains. Our team has the knowledge required to prepare systems design for any facility type including commercial, residential, governmental, and oil & gas facilities including processing plants.
While Neptune is experienced in the design of firewater systems within a number of industries, we specialize in the design of suppression systems for the Oil & Gas Industry. Neptune has designed systems for numerous Oil & Gas facilities including LNG, LPG, fuel terminals, onshore and offshore facilities, and processing plants.
Preparing the proper firewater system design for an oil and gas facility, specifically those such as LNG processing and storage facilities, require an expert understanding of the applicable codes and standards including NFPA and building code requirements, as well as industry best practices. Additionally, facilities with large amounts of flammable and combustible materials pose a complex challenge for the design of effective and efficient firewater systems.
Neptune prepares each design for these facilities with specific attention to the code requirements, and through the use of industry-leading software, with the goal of designing the best fire system design including the optimum protection for the prevention of injuries or loss of life, as well as to provide protection of facility commodities and structure.
