Bunkering HMI
1. Bunker Metering System – Features
The common method for verification of the fuel quantity received in a bunkering, is the measurement of tank levels. This method has the disadvantages of low accuracy and involves mass to volume calculation with an average temperature. Moreover, the air content caused by tank stripping and the potential “cappuccino effect” can’t be measured hence not to be included in any calculation. These are the main causes for claims between supplier and buyer. To counter these causes, ship owners and barge operators install special bunker fuel metering systems.
Electropneumatic SA has developed a bunker fuel metering system that complies with the OIML directions and is designed for installation both on barges and vessels. The core of our system is based on Coriolis principle for mass measurement and is supported by additional instrumentation to ensure safe bunkering operation and trust worthy data. The system is equipped with high performance computer units to cope with the real time algorithms for the
direct mass measurement of the fuel and its quality controls. The combination of the highperformance hardware and its sophisticated software prompts out a transparent real time logging of the bunkering operation.
The continuous and simultaneous monitoring and logging of below process parameters are
saved in a log file and can be used in case of a dispute or a claim:
The added value of our system is that provides several services and not just a measurement.
Key Features of our Bunker Fuel Metering System:
The system has also the option to be upgraded and feature a Web-Access service.The websystem transmits all data during a bunkering procedure to an onshore Data Center (ISO 27001 Cyber Security) for storage via satellite communications. The Web-Access feature does not affect the stand-alone operation of the Bunker Metering System. The data stored in the Data Center can be accessed by the client (credentials required) but data cannot be modified. The Bunker Metering System has the below additional feature with the Web-Access upgrade:
The installation does not include the piping modification for the mechanical installation of the Coriolis Mass Flow Meter(s) and any other instrumentation that should be connected on a pipe. A special attention to the size and weight of the Coriolis Mass Flow Meter should be given.
2.3 Site Survey
A Site Survey is recommended before Bunker Metering System installation. The site survey scope is to check and advise for any piping modification, repairs, works and cable run that should take place before the Bunker Metering System installation. The survey also aims to highlight the location where the new Bunker Coriolis Mass Flow Meter(s) should be installed, a critical milestone of the Bunker Metering System.
It is not recommended the site survey to be performed by the client. The site survey also aims to ensure an installation that will comply with OIML directives; a very specific piping for receive and / or supply fuel oil is required.
Electropneumatic SA has a troubleshooting technical team and skilled service engineers that offers you on site solutions to your electrical problems or misses. Any task that is not included in the scope of Bunker Metering System quotation will be treated as a separate service quotation.[/vc_column_text][/vc_column][/vc_row]
