Vessel Control Systems
Overview
DIASYS Netmation is used as a control system for liquefied natural gas (LNG) carrier vessels which carries out centralized control and monitoring of all aspects including the loading, transportation and unloading of cargo (cargo department), in addition to turbines and boilers (engine department) that make up vessel propulsion plants.
Utilizing high system performance and the expertise gained from many years in shipyards, we help LNG carriers achieve energy-saving operation and ensure the safe transportation of LNG.
Features
High Reliability Systems
In addition to hardware redundancies that include CPUs, power supply and networks, optimal distributed processing of signal I/O and control functions tailored to the plant configuration under control enhance reliability as a total plant control system.
Support for the Safe and Energy-saving Operation of LNG Carriers
Through total plant control features including LNG management, we support the safe and energy-saving operation of LNG carriers.
The solution also assists vessel operation through a range of data collection features, such as real-time trends that collect data in intervals as short as one second, and long-term trends able to record up to 500 days of all plant data.
System Configuration
Control systems for LNG carriers comprise engine department control systems and cargo department control systems, which are connected through a highly redundant network.
Basic Configuration
Operator Station (OPS) | Terminal to perform monitoring and operation. |
I/O Station (IOS) | This equipment is used for maintenance. Maintenance tasks such as the creation and modification of logic and graphics screens, as well as system setup are performed. |
Accessory Station (ACS) | Terminal to perform long-term data collection. Export to external media is also supported. |
Engineering & Maintenance Station (EMS) | This equipment is used for maintenance. Maintenance tasks such as the creation and modification of logic and graphics screens, as well as system setup are performed. |
Gateway Controller (GWC) | The controller serves as an interface for serial communication signals exchanged with external devices. |
Multiple Process Station (MPS) | Control equipment that performs I/O with instrumentation and other equipment installed on-site at the plant, as well as automated plant control and various computational processing. |
