198 IoT Applications — Value Creation for Industry
Fig. 3.22 4-20 mA HART has been available since 1990 and is mainly used for instrument commissioning
where an engineer connects a hand held at the instrument to configure parameters.
Therefore Statoil, ABB, IBM, Aker Kvaerner and SKF joined forces in an
R&D effort known as the CORD project in the beginning of the 2000’s to
develop new technology for more efficient operation of oil and gas field. The
objective was to develop technology, processes and knowledge to extend the
lifetime of Statoil’s oil and gas fields, and thus improve the recovery factor.
It was to evaluate, test and apply new and open standardized communication
system architectures that allow handling increased amount of data from field
devices to corporate systems in a cost-efficient and reliable manner.
The vision did not stop at the Field Devices but ambition is also to make
the maintenance workplace accessible both at site as well as in the onshore
operations center. Information should be possible to share both with internal
as well as with external experts, i.e., experts from the product or system
manufacturer thus facilitating co-operation between user groups and between
different locations.
Potential with wireless
Much of the envisioned solutions only become possible with wireless communication.
Wireless technologies have undergone various industrial trials over
the last years, which have demonstrated that wireless communication can be
