Onshore contract for PlantWeb
Published on EngineeringTalk.com

Emerson Process Management has
been selected by Costain Oil, Gas
and Process as a major instrumentation
and controls supplier for the Rivers
fields onshore processing facilities
being constructed at Barrow-in-Furness,
Cumbria.
Emerson will supply automation
engineering, project management,
and PlantWeb digital plant architecture
with Foundation fieldbus technology
for automation of new sour gas treatment
facilities.
Three of the five Rivers sour gas
fields in the east Irish Sea are
being developed by Burlington Resources
(Irish Sea) in a $260 million project.
The Rivers onshore facilities will
be automated by Emerson to receive
wet sour gas from the offshore platform
in the Calder gas field, which will
collect the gas from three Rivers
fields (Calder, Crossans and Darwen).
The plant will separate the liquids,
compress the gas to export pressure,
sweeten the gas by removing some
of the H2S (hydrogen sulphide),
and forward the gas to an existing
gas terminal for processing. In
setting requirements for the new
plant, Costain placed particular
importance on the optimisation of
capital and engineering costs, cabling
and commissioning time and costs,
and total cost of ownership.
The Emerson solution includes PlantWeb
architecture that reduces front
end time and cost through its DeltaV
digital automation system and AMS
predictive maintenance software.
These will communicate using Foundation
fieldbus technology over the PlantWeb
open, standard all-digital communications
network. The network approach delivers
best installation cost, and delivers
diagnostic data from plant instrumentation
and control devices to help diagnose
problems that might result in downtime
later on.
The DeltaV digital automation system
will include a 1500 channel input/output
subsystem, with fully redundant
controllers, Foundation fieldbus
H1 cards, analogue and serial interface
cards.
Emerson intelligent field devices
will include 400 Foundation fieldbus
capable instruments, including Rosemount
pressure and temperature transmitters,
and digital valve controllers. Emerson
RS3 control systems are used on
other existing Irish Sea production
platforms, and in other onshore
processing facilities: integration
with these systems was another important
requirement for the new processing
plant.
PlantWeb architecture achieves
this by using the capability of
the DeltaV automation system to
implement Simplex OPC interfaces
to the Emerson RS3 control systems,
and also by accepting serial interfaces
from gas compression control systems.
Through this integration, the DeltaV
system will provide the Rivers fields
operators with a single window to
both onshore and offshore operations.
