The use of methanol in the marine industry has been picking up in the last few years, and many companies are investing in methanol-propelled ships. When methanol is used as fuel, it needs to comply with the IGF code, IMO – MSC.1/Circ. 1621 Interim Guidelines for the safety of ships using methyl/ethyl alcohol as fuel and rules and regulations for the classification of ships using gases or other low-flashpoint fuels.
Radar-based solutions are the ideal technology. It is reliable and commonly used for large marine fuel tanks. Another strength is that only one level device is needed since the electronics can be replaced without compromising the tank integrity. In comparison, technologies that require tank entry in case of malfunction need more devices. Smaller methanol tanks require at least one continuous level measurement device and a high-high level alarm device.
The Rosemount 3408 Non-Contacting Radar Level Transmitter is a versatile FMCW radar suitable for level measurement and overfill prevention in many industries, including chemical. Smart features save time and maximize efficiency for trouble-free operations, simplifying commissioning, operation and testing. Smart diagnostics help you proactively plan maintenance and optional Bluetooth® connectivity allows convenient configuration and maintenance. Manual or automatic verification at scheduled intervals can be conducted from the control room at any time without process interruptions. Perform proof-testing remotely and in-situ with onboard functionality. NAMUR type tested and third party certified to IEC61508 for use in safety critical applications.
The Rosemount 2120 Level Switch provides easy to install, reliable level detection and control. 3 rdparty IEC61508 (SIL2) safety and hygienic certification with choice of outputs makes it suitable for a wide range of applications. It has no moving parts, needs no calibration and is virtually unaffected by process conditions. Adjustable switching delay prevents false switching in turbulent applications. Understand what is going on with your process- the visible heartbeat LED provides device status and health, and magnetic test point provides an easy-to-use functional test.
Operational continuity is key for your ship’s long-term success. With Aperio Software you get a single point overview of your ship’s systems, which improves your ability to plan, control, monitor and react to alarms. It’s designed to manage a variety of stand-alone systems for tank monitoring, valve and pump control fuel management and alarm acquisition. The Aperio is highly scalable and flexible with customizing capabilities for most any combination of tasks, for most any size of vessel.
