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. eral years with the sales depart- ment of one of the country's lead- ing shipbuilding and repair firms.

He is a member of the Propeller

Club, is an associate member of

The Society of Naval Architects and Marine Engineers, a member of the National Association of Cor- rosion Engineers, and a member of the National Paint, Varnish and

Lacquer Association.

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 of interlocking the barges and the variety o

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

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. 18
