W.F. Hunt To Manage
Fleet Services Division
For Trident Tankers
Trident Tankers, Great Britain's
largest independent tanker opera-
tor, has announced the appointment
of William F. Hunt as general
manager to head its fleet services
division.
Earlier this year, the P and O
subsidiary reconstructed its opera-
tions into three distinct fleets—
tankers, liquid gas, and oil/bulk/
ore carriers.
Mr. Hunt, who served at sea in
two tanker companies for over a
decade, before joining the marine
department of the Hong Kong gov-
ernment, will supervise the person-
nel, fleet supplies and work study
departments as his chief responsi-
bilities.
Japan's giant Nippon Steel Cor-
poration has signed its first con-
tract for iron ore concentrates to
be delivered by the use of Marcona-
flo, it was announced in San Fran-
cisco by C.W. Robinson, president,
Marcona Corporation. Marconaflo
is the slurry method of materials
handling which was developed and
introduced by Marcona. (See Au-
gust 15, 1969 issue of Maritime Re-
porter/Engineering News for fea-
ture with complete description and
photos).
Under a 10-year, $113-million
contract, Marcona will deliver 10
million tons of concentrates, begin-
ning in April 1972, via the Mar-
conaflo system from its iron ore
mines in Peru to Nippon Steel's
Hirohata Steel Works, where it
will be converted into pellets for
the production of steel.
Marconaflo permits shipboard
pipeline loading of granular ma-
terials in slurry form or liquid
suspension, subsequent decanting
for the ocean voyage, and at desti-
nation, repulping of the ore into a
liquid for pipeline discharge.
"This is a breakthrough of ma-
jor proportions," Mr. Robinson
said. "Marconaflo has now been ac-
cepted as a viable means of meet-
ing the transportation crisis which
faces the world's steel producers.
"Application of Marconaflo to
such an operation eliminates the
need for an expanded, multimil-
lion-dollar conventional port fa-
cility employing the massive con-
veyor and grab bucket systems re-
quired for delivery of ore in dry
form."
To accommodate the required
one-million tons of annual ship-
ments, Marcona will employ two
large slurry ships with a combined
capacity of 192,446 deadweight
tons.
The San Juan Exporter, an ex-
isting Marcona ore carrier of 106,-
000 dwt, will immediately undergo
a jumboizing and conversion oper-
ation to expand capacity to 141,000
dwt and for installation of Mar-
conaflo equipment. The converted
vessel will be capable of delivering
nearly 850,000 tons per year.
The remainder of the contracted
ore will be carried by the Marcona-
flo Merchant. This vessel became
the world's first slurry carrier when
converted to the system last year
in Japan.
While the San Juan Exporter is
being converted, Nippon Steel will
construct a large, ground-level
storage pond to receive the iron
ore slurry, and a pelletizing plant
adjacent to its existing steel works.
Marcona Corporation, owner of
combination carriers with an ag-
gregate of one-million dwt and op-
erator of a total of 2.5 million tons
in the combination trades, is one
of the world's largest mining, ship-
ping and natural resources de-
velopment concerns.

The San Juan Exporter, huge ore carrier shown above, owned by Marcona Corporation,
Son Francisco, will be jumboized from a present 106,000 dwt to 141,000 dwt and
converted to the company's recently introduced Marconaflo slurry system.
WORLD'S LARGEST TUG-BARGE: This architect's drawing shows how the world's
largest tug-barge will look when it is launched early next year. The unique vessel is a
combination of one of the country's most powerful tugboats firmly nestled in the notched
stern of a 532-foot tanker barge. Built with high-strength, notch-tough Armco Low-
Temp Steel in critical bow-stern connecting sections, it will travel as a unit ocean routes
never before attempted by o tug and barge. Ingram Ocean Systems and Breit Engineer-
ing Company co-developed the system. It combines the speed and capacity of an ocean-
going vessel with the economy of tug and barge transportation. Tank and dry-cargo
barges can be used for quick dockside turnaround of the tug and crew. Alabama Dry
Dock and Shipbuilding, Mobile, will build the first barge, a 270,000-barrel capacity
tanker. Southern Shipbuilding Corp., Slidell, La., is building the 1 1,000-hp twin-screw
tugboat.
They put real muscle in bow and
stern thrusters, too.
