The Application Of Pressure Equipment In The Maritime Industry（1）

September 29, 2024

Overview of the Shipping Industry

Ocean transportation, also known as “international ocean transportation”, is an industry that provides maritime passenger or freight services and is the most important mode of transportation in international logistics. It is a method of using ships to transport goods between ports in different countries and regions through sea lanes, and is the most widely used in international cargo transportation.
Among them, there are several key components on board, including oil and gas systems, cooling systems, hydraulic systems, water systems, and fire protection systems. Pressure switches play an important role in monitoring various aspects of pressure to ensure.

Measuring Solution for Shipbuilding

・Petroleum System

Specific Applications
1. Oil and gas transportation monitoring: In ship oil and gas systems, pressure transmitters are used to monitor the pressure inside oil and gas pipelines, ensuring the safety and stability of the transportation process, and preventing leakage and explosion risks.
2. Fuel supply regulation: The pressure switch can monitor the pressure changes of the fuel system in real time, automatically adjust the operating status of the fuel pump, and ensure that the engine obtains stable fuel supply.
3. Safety valve control: The pressure transmitter is linked with the safety valve. When the pressure exceeds the set value, the safety valve automatically opens to release excess pressure and protect the system safety.

Challenge
1. High pressure environment: Ship oil and gas systems are often in a high-pressure state, and pressure equipment needs to withstand significant pressure fluctuations, which can easily lead to equipment failure.
2. Flammable and explosive gases: There are flammable and explosive gases in the oil and gas system, and the explosion-proof performance requirements of the equipment are extremely high. Any mistake may cause serious consequences.
3. Space limitation and maintenance difficulty: The limited internal space of the ship poses challenges for the installation, maintenance, and replacement of pressure equipment, which may lead to delayed maintenance.

Solution
1. High pressure design and material selection: Select pressure switches and transmitters specifically designed for high-pressure environments, using high-strength alloy materials to ensure the reliability of the equipment under extreme conditions.
2. Explosion proof certification equipment: Use pressure equipment that meets international explosion-proof standards to ensure safe operation in flammable and explosive environments and reduce the risk of accidents.
3. Remote monitoring and diagnosis: Combining IoT technology, establish a remote monitoring system to monitor pressure changes in the oil and gas system in real time, and predict faults through data analysis, reducing the frequency of manual inspections and improving maintenance efficiency.

Value of the Solution

Pressure switches and pressure transmitters play important roles in ships. Pressure switches are used for safety monitoring and automatic control, capable of cutting off equipment power or issuing alarms in case of abnormal pressure, ensuring system safety. The pressure transmitter provides accurate pressure measurement data, supports data collection and analysis, and helps crew members monitor and diagnose potential faults in real time. The combination of the two has improved the safety, efficiency, and reliability of the ship system.
