G r o w t h aimid coosolidatioiii

The Norwegian Ulstein Group has

come a long way

f r o m

a small yard

perched on an island repairing fishing

boats to a major shipbuilding and

equip-ment Group, employing a significant

percentage of the labour along the

Nor-wegian coast and with subsidiaries i n a

number of countries abroad.

I f it was the offshore support vessel

which laid the basis of Ulstein's current

fortunes with some 220 of the U T 700

series, designs built either at the

Group's own yards or by others under

licence. I t is interesting to see that as

the CSV construction market revives,

it is U T designs, albeit m o d i f i e d , which

are once again in demand. However,

nowadays conventional shipbuilding is

only a part of the scene and marine

equipment is responsible for much of

the

Group

's prosperity while a major i n

-vestment in the..design, construction

and propulsion of high speed vessels,

primarily air cushion catamaran ferries,

promises to consolidate the Group's

po-sition i n a buoyant present and future

market.

I n a report in Ship & Boat seven

years ago on the Ulstein Group, we

not-ed "Absent f r o m the Ulstein philosophy

is any element of pre-assumed growth

in any specific direction, what is there

is a belief in the ability to survive

healthily or with healthy potential

through own efforts, innovation and i m

-agination. With maybe a dash of luck

and little seat of the pants instinct.

Broad directional constraints are i m

-plicit in the criteria by which any new

project is first vetted; one, is it

techno-logically within Ulstein's province; two,

is it suited to the production structure;

where can the Group market it

effec-tively? Thus Ulstein innovativeness

tends to be channelled

to

the shipping

and offshore fields, or first cousin

tech-nologies such as materials handling and

metal fabrication."

Ulstein S u p p l e m e n t

This philosophy seems to have stood

the Group i n good stead and still

ap-plies.

Viewed f r o m outside Norway,

Ulstein Group's organisation into a

large number of relatively small

com-panies scattered up and down the coast

appears curious. Why not reap some

benefits of scale by consolidating into

fewer sites? The Group's President,

Idar Ulstein, points out the special

fac-tors i n the way the Group has grown

and i n the conditions which obtain in

Norway. Acquisition of the Bergen

Group in 1985 virtually doubled

Ulstein's size. Since then other

acquisi-tions have brought within the Group

what were previously self contained

companies. There is an interest in

re-ducing the number of units but there

are definite constraints. Sales and

mar-keting, f o r example, is now handled in

general f o r the whole Group by Ulstein

International. It is only Norwinch and

Bergen Diesel who in addition have

their own sales departments.

Small companies demand more total

management than large ones and the i n

-tention is to merge some of the yard

activities, structuring, f o r example,

steelwork as f o u r departments not three

yards. But there are strong limitations

on building larger units, forced by the

nature of Norwegian society where

most of the population lives in small

towns and villages scattered along a

long coastline, many of the

communit-ies being on small islands relying

entire-ly on ferry traffic f o r their

communica-tions with the mainland.

The size of the " K o m m u n e " limits

the size of the company to the available

labour force, unless complex and costly

arrangements are made such as

current-ly at Hyen and E i k e f j o r d to provide

ac-commodation f o r workers f o r whom

daily travel f r o m home to the yard

would be prohibitive i n time.

Mr Idar Ulstein, president of tt\e Ulstein group.

The other risk with large companies

in small communities is the cyclical

na-ture of the marine business, so f o r a

community's overall prosperity, it is

de-sirable to have a balanced mixture of

industries which dance to different

tunes. The main Ulstein base at

Ulsteinvik on Hareid is a m a j o r

em-ployer of local labour i n seven of the
