BENEFITS SUMMARY
Flexibility allowing multi-stream, multi-station
applications to be confi gured for simultaneous metering
of both liquids and gases
Hot cutover eliminated system downtime during a major upgrade
Reduced future maintenance and cost with availability of
spare parts, ensuring maximum productivity
APPLICATION
Offshore Oil & Gas f i scal metering systems
CUSTOMER
Maersk Oil in Denmark
CHALLENGE
Maersk had over 30 old Sentinel 500 fl ow computers installed on
their offshore platforms that were having obsolescence issues. With
the lack of available spares and support for the aging f l ow computer
and DEC supervisory computer, the risk to their metering operations
greatly increased. Their entire operation was at risk particularly
in losing fi scal metering data to accounting systems, associated
partners and third parties.
SOLUTION
Maersk chose the FloBoss S600+ to provide fl ow measurement
and monitoring functions for totalization, alarm monitoring, valve
monitoring and control. Their front end metering is performed by 11
FloBoss S600+ f l ow computers. The system confi guration involves
dual stream gas orifi ce, dual stream liquid turbine, four stream
Coriolis meter and four stream VCone.
The FloBoss S600+ is designed to provide standalone fl ow metering.
The OPC server will collate the data from each FloBoss S600+ fl ow
computers and pass this to the Maersk control system. The OPC
Server is used as an interface between the FloBoss S600+ Flow
computers and the Maersk control system.
Maersk acknowledged the FloBoss S600+ is the ideal replacement
and provides the functionality they require. This versatile fl ow
computer can be confi gured to meet their specifi c requirements.
During this hot cutover, the installation into existing cabinets has
proven to be straightforward with minimal disruption to metering
operations during the change out period. Maersk continues to work
with Emerson and has confi dence in their professional approach,
wide knowledge and experience of fi scal metering systems.
Emerson continues to offer fl ow computer solutions including
upgrades and EExd cabinets for installation in hazardous areas.
