MEASURING EQUIPMENT TO ENSURE OFFSHORE SAFETY

We believe it is only responsible to offer this to the offshore market as well because we know that rollover and stratification can occur both onshore and offshore. Despite the lack of regulations in this area, we believe that investing in measuring equipment offshore is the only right decision to ensure workplace safety.

A reliable and proven technology

LNG storage facilities must have precise instruments that measure temperature, density, and level variations. Our LTD gauge is a part of our total LNG storage tank instrumentation solution. This is the world’s most advanced LTD gauge currently available on the market. With more than 330 installations in onshore LNG tanks worldwide, we ensure a reliable and proven technology.

Comprehensive Solutions for LNG Storage

At Svanehoj, we offer more than standalone instruments. Our solutions encompass complete safety systems tailored to onshore LNG operations. The LTD Gauge is complemented by advanced systems like the Data Acquisition System (DAS) to provide seamless monitoring and control of offshore storage.

Data Acquisition System

The Data Acquisition System (DAS) is a critical component for monitoring LNG storage tanks. It serves as a hub for collecting and processing data from field instruments, ensuring seamless communication with the terminal’s Distributed Control System (DCS).

THE DATA ACQUISITION SYSTEM IS COMPOSED OF

The PLC-based acquisition system.
The HMI in the control room.

KEY FEATURES

Redundant architecture: The DAS offers full redundancy for power supply, I/O modules, and CPUs, ensuring uninterrupted operations.

Enhanced security: The DAS offers full redundancy for power supply, I/O modules, and CPUs, ensuring uninterrupted operations.

Modular design: A flexible, scalable architecture supports system evolution and upgrades.

Data communication: Equipped with redundant Ethernet and RS 485 Modbus connections, the DAS facilitates reliable data transfer.

Rollover Predictive Software

The Rollover Predictor is advanced software designed to prevent LNG stratification risks. The rollover prediction software integrates an automatic mode where the chemical composition calculation is based on measured parameters (density, temperature and operating pressure) from the LTD gauges.

KEY FEATURES

Real-time composition monitoring: The DAS offers full redundancy for power supply, I/O modules, and CPUs, ensuring uninterrupted operations.
Predictive capabilities: The DAS offers full redundancy for power supply,
I/O modules, and CPUs, ensuring uninterrupted operations.
Automatic integration: A flexible, scalable architecture supports system evolution and upgrades.
Validated accuracy: Its predictive models have been experimentally validated for precision.
