On Wednesday afternoon, under
the chairmanship of R. Lewis Rid-
ings, Lewis Technical Services,
Inc., U.S., the subject will be Com-
puter Analysis in the Offshore In-
dustry. A total of six papers will
describe new roles for computers in
supervision and control, in preven-
tive maintenance, in integrated
management systems yielding new
kinds of information, and in solving
technical problems too complicated
to be attempted by traditional
methods of calculation.
Among the speakers will be Da-
vid Lloyd of Racal-Norsk Ltd.,
U.K., who will discuss artificial in-
telligence systems applied to the
offshore industry, while Alan Jar-
dine of P.A. Computers and Tele-
communications, U.K., will present
a paper entitled Computers and the
Leading Edge.
In what promises to be an ex-
tremely interesting session on Tues-
day morning, six papers will be pre-
sented to show how the flexibility
afforded by floating and semisub-
mersible structures can reduce capi-
tal expenditure and lead times for
offshore oil and gas production
plants. Advances in design may ena-
ble marginal fields to become eco-
nomically viable.
This session, chaired by Arne
Berglie, technical director of Go-
taverken Arendal AB, Sweden, will
include a paper from Peter Met-
calf of Canocean Resources (UK)
Ltd. titled Commissioning and
Maintenance of Subsea Systems.
Bernard Barthelemy of Coflex-
ip, Norway, assisted by Chris-
tophe Perrenati of Coflexip,
France, will present a paper on
Flexible Risers for Early Production
and Testing Vessels. Paul E. Sulli-
van, chief engineer of Murdock En-
gineering Company, U.S., will speak
on high-technology elastomeric de-
vices, and Hans Petter Jacobs-
en, principal surveyor of Det norske
Veritas, Norway, will wind up the
session with some observations on
the classification and certification
of floating production systems.
Eivald M.Q. Roren, executive
vice president of Det norske Veritas,
will chair a special session on Tues-
day morning that will focus on
methods and technology for periodi-
cal inspections. The economy and
safety aspects of system surveys will
also be covered. Among papers to be
presented at this session are Deep
Sea Production Systems—Trends
in Surveillance and Repair, from
Bjorn Husemoen of Kongsberg
Vapenfabrikk, Norway, and Quality
Assurance through Verification,
from Bjorn Blaker, head of off-
shore activities at DnV.
On Tuesday afternoon Prof. Tom
Floden, associate professor at the
University of Stockholm, will pre-
side over a session at which papers
will be presented on new methods in
three-dimensional seismic survey-
ing, developments in airborne sur-
veillance systems, and the interpre-
tation of data.
In a paper on new methods for 3-
D seismic data acquisition, M.
Brink, head of R&D at the Geo-
physical Company of Norway A/S,
will consider how two separate
streamers towed by a single vessel
Circle 306 on Reader Service Card
can collect data from two adjacent
lines in one pass, and the advan-
tages of using two vessels to circum-
vent obstructions and save time.
Cdr. Staflfan Kvarnstrom of the
Swedish Coastguard Service will
read a paper titled Aerial Surveil-
lance of Coastal Waters—New Air-
borne Systems Developed by the
Swedish Coastguard.
During morning sessions on Wed-
nesday and Thursday a total of 10
papers will describe different posi-
tioning, anchoring, and mooring sys-
tems. Pontus Clason of GVA,
Sweden, and Ingvar Rask of
SSPA, Sweden, will discuss Reso-
nance of Semisubmersible Mooring
Systems Due to First Order Wave
Forces. Kaj Wendel of Chalmers
University of Technology, Sweden,
will examine the use of probability
analysis in the dimensioning of an-
choring systems. A paper from D.
Kypke of Brown & Root (UK), S.
Guy of Heerema Ltd., U.K., J.
Chivvis of Conoco (UK) Ltd., and
L. Bystrom of SSPA, on successful
installation of the first tension-leg
platform in July 1984 in the Hutton
Field of the North Sea, is likely to
be of particular interest.
A panel session on Wednesday
morning will discuss the relative
merits of steel and concrete for plat-

JOTUN MARINE COATINGS BREAKS THE BARRIER IN COPOLYMER TECHNOLDGY
Now you can say goodbye to the old long-life antifoulings.
JMC has broken the barrier in copolymer technology and is now
introducing a selfpolishing coating at the same price as a long-life!
This means selfpolishing protection at no extra cost, with such benefits
as no roughness build-up, less risk of cracking and no "sandwich
coatings".
SEACONOMY is the name of the antifouling and only JMC can offer
this particular technology? 'It's the way to the selfpolishing concept for
owners who have been stuck with long-life antifoulings because of price,
uncertainty in the business, short-term investments etc.
Seaconomy can be applied to most existing antifoulings without a
sealer. At subsequent drydockings it may also be upgraded to the
higher-level protection of Seaflex or Seamate High Build.
Doesn't it sound like a tempting proposition?
JMC - the innovator in copolymer technology -
working for the owners.
SEACONOMY KISSES THE OLD ANTIFOULINGS
GOODBYE!
