Container Ship Loading/Unloading Simulation
Subject Of SNAME Hawaii Section Meeting
Shown seated at the head table are, left to right: J.A. Gilbert, social activities chairman,
1971 Spring Meeting; Capt. Kenneth Wilson, USN, program chairman; Bruce Nehrling,
author; Dave Kearton, chairman; Robert Mende, national secretary; Ian Smith, chair-
man 1971 Spring Meeting; and Theodore Otero, executive committeeman.
The Hawaii Section at its Au- ship, containers, container-handling
gust meeting at the Ala Moana
Banquet Hall, Honolulu, enjoyed
a social hour and dinner before the
technical session.
A paper entitled "Container
Ship Loading and Unloading Sim-
ulation" was presented by Bruce
C. Nehrling, a graduate naval ar-
chitect from the University of
Michigan, College of Engineering.
Mr. Nehrling, whose visit to Ha-
waii for this purpose was sponsored
by M. Rosenblatt & Son, was in-
troduced by Capt. Kenneth Wilson,
Commander of Pearl Harbor Na-
val Shipyard.
Mr. Nehrling described his com-
puter program, which was written
in GPSS (General Purpose Sim-
ulation System) for the IBM 360
computer. With the help of a slide
projector and a table display graph-
ically depicting container move-
ments he explained his computer
simulation of the operations of a
system consisting of a container-
vehicles, a terminal yard and a
dockside crane. Interaction among
system components is monitored
along with ship displacement,
stability, trim and list during the
simulation. He pointed out the
value of the computer simulation
in allowing management to con-
sider and test many options and
conditions with the use of his pro-
gram.
The presentation was of espe-
cial interest to a guest, John Mil-
ler, general manager, operations, of
Sea-Train Lines and to member
Ted Otero, representing Matson
Lines, both of whom are heavily
involved in seaborne container
freight to the islands of the Pacific.
Robert Mende, national secre-
tary of SNAME, was also present
in connection with Hawaii's 1971
Spring Meeting plans. Mr. Mende
commented on the consistently
high turnout of the Hawaii mem-
bership at their Section meetings.

Jakobson Shipyard Builds Twin-Screw Tug
For Texaco's Port Arthur, Texas Fleet
Shown shortly after launching at the Jakobson Shipyard in Oyster Bay, the Houma
will be employed by Texaco on the intercoastal waterway.
A new tug, the 200-ton Houma
II, built by Jakobson Shipyard in
Oyster Bay, N.Y., recently joined
Texaco's Port Arthur Tug Boat
Fleet.
Mrs. Kay Walker of Post Ar-
thur. wife of Texaco U.S. Fleet
manager, R.P. Walker, served as
sponsor of the new tug during the
recent christening ceremonies at
the Jakobson yard.
Equipped with hydraulic steering
gear and twin screws, the Houma
II is of conventional design. Pow-
ered by two General Motors diesel
engines of 975 horsepower each,
the new tug is equipped with the
latest navigational gear, including
radar and VHF radio. She is fully
air-conditioned and semi-automat-
ed, meaning she is controlled en-
tirely from the bridge.
Master of the new tug is Nils
Geitrheim of Warren, Texas. Chief
engineer is O.J. "Doc" Pulliam of
Groves. The main job of the Hou-
ma II will be to handle barges in
the delivery of light products such
as gasoline and lubricating oil be-
tween Port Arthur and cities along
the intercoastal waterway. Two of
the other tug boats in Texaco's
Port Arthur fleet, the Houma and
the Ursa, have been moving barges
on the intercoastal for more than
20 years. Another tug, the Havo-
line, is used only in the Port Ar-
thur area.
Twin City Shipyard Producing
Specially Designed Portable Barges
PORTABARGES being used to support a pile

Twin City Shipyard. Inc. has re-
cently developed a novel concept
in the integration of portable barges
into larger-size flotation or bridg-
ing units. John Buursema, execu-
tive vice-president and general
manager of the firm, states that the
variety of applications for these
units is almost endless, including
pile-driver pontoons, crane barges,
bridge pontoons, cargo barges,
mooring docks, beaching units, fer-
ries, etc.
The patented system of PORT-
ABARGES (registered) allows the
customer to assemble the required
flotation unit into any shape and
size consistent with specific service
requirements. A wide range of ac-
driver. This view shows the patented method
f shapes that can be formed.
cessory equipment, such as bow
rakes, spuds and spud wells, pro-
pulsion units, etc. are also avail-
able.
PORTABARGES are designed
and precision built to exact dimen-
sional standards with uniform light
draft within each series, making the
barges interchangeable. The ex-
clusive deck fittings enable lesser
skilled personnel to assemble the
units. These same fittings are used
for balanced lifting.
PORTABARGES can be pur-
chased outright, rented or rental-
purchased. Full details on these
units may be obtained from Twin
City Shipyard, Inc., P.O. Box 3032,
St. Paul, Minn. 55101.

Largest Marseilles
Drydocking Handled
By Terrin Shipyards
The Texaco Hamburg, a tanker of
208,900 dwt, built in 1969 by the
West German yard of Hohwaldts-
werke-Deutsche Werft for the Brit-
ish firm, Texaco Overseas Tankship
Ltd., arrived at Marseilles on Sep-
tember 1 for repairs and guarantee
drydocking at Terrin shipyards (So-
ciete provencale des ateliers Terrin).
This vessel, with an overall length
of 1,067 feet, a molded breadth of
154 feet, and a draft of 62 feet, is
the largest vessel to have been dry-
docked at Marseilles, and the record
seems likely to stand until the com-
missioning of the new Marseilles
floating dock, capable of handling
ships of up to 350.000 dwt.
