LGIP Engine : Part 2 - LPG Fuel Supply System - Deck tank

LPG fuel supply system - Deck tank.
An LPG (liquefied petroleum gas) Fuel Supply System with a deck tank is a specialized setup used in marine vessels where LPG is used as a fuel source. The deck tank is a type of storage tank that is installed on the deck or upper structure of the vessel, and it is used to store LPG for use as fuel for various shipboard applications, such as propulsion, heating, and cooking. The LPG Fuel Supply System with a deck tank typically includes the following components:
Deck Tank: The deck tank is a specially designed storage tank that is installed on the deck or upper structure of the vessel. It is constructed to withstand the harsh marine environment and is typically equipped with appropriate safety features such as pressure relief valves, emergency shut-off valves, and level sensors.
Pressure Regulators: Pressure regulators are used to control the pressure of the LPG as it is delivered from the deck tank to the equipment or processes on the vessel. They ensure that the LPG is delivered at the correct pressure for safe and efficient combustion or utilization.
Control Valves: Control valves are used to regulate the flow of LPG from the deck tank to the equipment or processes. They are typically actuated valves that can be remotely controlled to open or close the flow of LPG as needed.
Filtration System: The filtration system is designed to remove any contaminants or impurities from the LPG before it is supplied to the equipment or processes. This helps prevent damage to downstream components and ensures reliable operation.
Safety Devices: Safety devices such as pressure relief valves, emergency shut-off valves, flame arrestors, and leak detection sensors may be included in the LPG Fuel Supply System to ensure safe operation and prevent accidents.
Instrumentation and Control: Instrumentation and control components such as flow meters, pressure gauges, temperature sensors, and level sensors may be included to monitor and control the LPG supply system parameters.
Piping and Connections: Piping and connections are used to transport the LPG from the deck tank to the equipment or processes on the vessel. These are designed to meet safety standards and ensure reliable flow of LPG.
Electrical and Control Panels: Electrical and control panels may be included in the LPG Fuel Supply System to provide power supply, control, and monitoring for the system components.
Vapour Return System: In some cases, a vapour return system may be included in the LPG Fuel Supply System to capture and return any excess LPG vapors from the equipment or processes back to the deck tank, ensuring efficient and safe handling of LPG vapors.
The LPG Fuel Supply System with a deck tank is designed to provide a safe, reliable, and efficient source of LPG for marine vessels that use LPG as a fuel. Proper design, installation, operation, and maintenance of the system are essential to ensure safe and efficient operation of the LPG fuel supply system on board the vessel.

Excellent

[@reycantor7398]

sir PCV 1213, where that line is going? you said that is used to relieve tank pressure before bunkering. But where that line is connected?..thanks

[@meoexams]

That is connected to cargo tank vapour system.
