many forthcoming projects will be “firsts” for their respective operators
decommissioning projects have largely been “one‐offs”
limited opportunity for learning and knowledge transfer
decommissioning cost estimates continuing to increase
early
contractual
experiences
not
always
happy ‐
for operators
or
contractors
industry now genuinely seeking more co‐operation and innovation
new technologies needed
some observations from 2010 Conference

cross sector research ‐ what can we learn ?
nuclear
first workshop in March 2011 ‐ joint
working with ITF and Scottish
Enterprise
second workshop
16
November
2011 in Glasgow – joint working
with Nuclear Industries Association
salvage
initial seminar in December 2010 ‐
joint working with SUT
second
seminar on
6th
December
2011 in London – again with SUT
potential synergies being identified and progressed

nuclear strategy ‐ next 10 years
all Magnox stations
to
have
been
de
‐fuelled
and
spent fuel reprocessed to a long‐term stable form
three of the Magnox sites to have entered the Care
and Maintenance phase in readiness for final site
clearance significant progress to have been made on high
hazard reduction programmes ‐ this includes the
retrieval of materials from Legacy Ponds and Silos at
Sellafield
the management of all NDA sites to have been
competed
all
NDA’s
non
core
assets
to
have
been
disposed
of to commence Surface‐Based Investigations Phase for
the Geological Disposal Facility (GDF).

top 3 challenges identified from first
nuclear / oil
&
gas
workshop
from nuclear
:‐
condition monitoring
waste reduction
remote underwater handling for active
waste storage
from oil & gas :‐
cutting technologies
NORM issues
mattresses

possibilities with the salvage industry
initial focus resulting from December 2010 conference
possible use of standard form contracts in O&G decommissioning projects
use of
(smaller)
salvage
lifting
vessels
and
techniques
review of cutting and underwater visualisation technologies, plus design
for decommissioning
review of marine science topics – noise, disturbance, colonisation etc
agenda items for December 2011 conference
concept of oil & gas platforms achieving “hydrocarbon free” status
comparison of contractor selection and mobilisation criteria
joint salvage & oil & gas committee meets 3‐4 times each year
to progress the possibilities
