Use of Glass Reinforced Epoxy (GRE) Piping for Fire Water Applications – Offshore

The fire water system on an offshore facility is a critical system. In the event of a fire, this system must not only deliver water for active fire management, but the system must also survive the worst-case scenarios of blast, jet fire and or hydrocarbon fire and for a duration anticipated in that scenario. The fire water system must also survive the duration of time needed for the safe evacuation of personnel from the facility.
This paper addresses the complexities involved in the use of composite pipes for fire water applications. It focuses on how blast effects are managed and the survivability of GRE piping in highly intense and high heat flux fire cases. Results from tests simulations will be shared which were carried out to assure certifying body, operator and engineer that GRE piping is the right material of choice for this application under such circumstances.
The paper concludes with examples of several floating production and storage offloading facilities installed with GRE piping for the fire water application.

Corrosion, either internal or external, along with other types of defects on pipelines eventually lead to leaks without proper treatment. This gives rise to several issues, including environmental and safety hazards, and in case of pipe leaks in a plant, a loss of the efficiency of the process or, ultimately, failure of the process. Replacing the corroded pipelines (piping) can be difficult, costly and time consuming especially for plant. A required shutdown causes major economic loss. Thus, instead of a replacement of the defected pipelines, the installation of online repair is a better option.
Repairs of pipelines include metallic and non-metallic repairs. Metallic repairs generally require welding or hot works which is not suitable for online repair of pipes containing hydrocarbons. In such cases the use of non-metallic composite repairs is the optimum solution. A non-metallic composite repair system is a system used to reinforce structures using a fiber equipped with a thermoset epoxy system. The epoxy system consists of a hardener and a resin which, after mixing, become solid through a polymerization reaction after a short duration of time, a process that is called curing. Depending on the temperature, the duration of time changes in an inverse relation. The higher the temperature, the smaller the duration of time needed for curing. This system can be used to reinforce pipelines with both external and internal corrosion and it can be used on Straight Pipes, Tees, Elbows, Flanges and weld joints. The repair system can also be installed online without the need for a shutdown in a short amount of time and a small requirement of labor intensity, making it cost effective. It is also environmentally friendly. In this paper we are going to present cases that were resolved by our company that demonstrate how successful these non-metallic composite repairs are and how diverse their applications can be
