ries. This sale will increase the fleet of Hovermarine craft oper- ated by HYF to a total of 20.
They will be employed to aug- ment various services within
Hong Kong and the 90-mile route between Hong Kong and Canton,
People's Republic of China. Value of the contract is in excess of 2 million pounds ($4.6 million), and calls for deliveries in late 1981.
The vessels will be built at Vosper
Hovermarine's works at South- ampton.
Participants at recent Philadelphia Section SNAME meeting included: (seated, L to

SNAME Philadelphia Section
Discusses Finite Element Method
The Philadelphia Section of The
Society of Naval Architects and
Marine Engineers met at the En- gineers Club recently for the presentation and discussion of the technical paper Fundamentals and Applications of the Finite
Element in Analyzing Structural and Non-Structural Marine Prob- lems. The paper, written by Dr.
Donald Liu and Dr. Yung Kuang
Chen, both of the American Bu- reau of Shipping, was presented to 55 members and guests follow- ing cocktails and dinner. A dis- cussion and a general question session followed the presentation.
Since the development of the finite element method (FEM) in the sixties, it has become a widely used and.significant means of ship structures analysis and structural analysis in general. Not only has the number of users of FEM in- creased but so has the variety of applications increased from stress analysis to magnetohydrodynam- ics.
The paper illustrates the use of
FEM in solution of complex struc- tural problems such as web frame stress analysis, analysis of stress in propellers whose complex shapes (high skew, large blade sections) can be adequately mod- eled with FEM and the stress an- alysis of complicated jackup drill rigs. The paper also includes il- lustrations and examples of vi- bration analysis using FEM, most notably the modeling of an entire tanker, including deckhouse, to determine the dynamic response of the tanker to propeller-induced vibratory forces.
Following the presentation, Dr.
Bernard McNamee (Drexel Uni- versity), Gary Mauers (Delaval), and William Toner (Delaval) each presented a discussion of the pa- per. Dr. McNamee noted the ben- efits and trade-offs of FEM, as co***o Hotuooe ~ a
Ings .r well as some introductory FEM textbooks. Messrs. Mauers and
Toner illustrated the use of FEM at Delaval for turbine and gear design. The three discussors as well as the topic presentation gen- erated a lively and interesting de- bate with the audience.
Also of note was a presentation honoring Kees Gyswyt(J.J. Henry
Co., Inc.) for his outstanding work as last year's Section chair- man.
Vosper Limited Group
Gets Three Contracts
Worth $29 Million Total
Vosper Limited, naval craft de- signers and builders, fast boat, and SES specialists, reports that its two main manufacturing sub- sidiaries, Vosper Private Limited,
Singapore, and Vosper Hoverma- rine Ltd., Southampton, U.K., have recently received orders worth more than 12.5 million pounds (about $29 million).
Vosper Private will build three 32-meter firefighting boats val- ued at 7.4 million pounds ($17 million) for the Saudi Ports Au- thority. It will also be responsi- ble for the operation and main- tenance of these vessels for three years. Under another contract, a technology transfer agreement of around 3 million pounds ($7 mil- lion), the company will provide subcontracting, consultancy, and training support for the construc- tion of six 32-meter, Vosper- designed fast patrol boats for the
Royal Malaysian Customs and
Excise. The vessels will be built by Malaysian Shipyard and En- gineering Company.
Vosper Hovermarine's latest contract is from the Hong Kong
Yaumati Ferry Company Ltd. (HYF) for four additional Hov- ermarine 218 fast passenger fer-
Newest Waterman Steamship
LASH/Containership Enters Service
The Edward Rutledge (shown above), a lighter-aboard-ship (LASH) vessel built for Water- man Steamship Corporation by
Avondale Shipyards Inc., made her maiden voyage arrival at the
Port of New York recently. The second of two LASH carriers built by Avondale recently for Water- man, the Rutledge was christened at the Avondale yard near New
Orleans in 1980 by Mrs. William
Amado, daughter of Edward B.
Walsh, president of Waterman
Steamship.
During her maiden arrival, Mc-
Allister Brothers docking master
Capt. William Gato reported that the 40,921-dwt Rutledge, which is fitted with a bow thruster, "han- dled well" as she was assisted into her Brooklyn berth by the 4,300-bhp tug Roderick McAllister and the 4,200-bhp Kort-nozzled
Bruce McAllister.
The newest addition to the Wa- terman fleet was named for Ed- ward Rutledge, a distinguished member of the First and Sec- ond Continental Congresses, who signed the Declaration of Inde- pendence representing South Car- olina. Mr. Rutledge, a Federalist, later was elected Governor of
South Carolina.
The Edward Rutledge has an overall length of 845 feet 4 inches, molded beam of 100 feet, and depth to main deck of 60 feet.
Designed by Friede and Goldman,
Ltd. of New Orleans, she is a 32,000-shp, single-screw, turbine- propelled barge carrier/container- ship with a service speed of 22 knots and cargo capacity of 1,744,400 cubic feet.
The new vessel will serve ports along the Red Sea, Arabian Gulf,
India, and Pakistan. She is ar- ranged for the carriage and inde- pendent handling of 89 LASH type barges, each with a cargo capacity of 370 long tons, that are loaded in seven holds and on deck. The ship is equipped with her own 510-ton gantry crane mounted on rails that run her full length. The crane loads and discharges barges over the stern, permitting operation independent of shore facilities.
Waterman Steamship Corpora- tion was founded with a single ship in 1919 in Mobile, Ala. Sail- ings to Puerto Rico were inaugu- rated in 1927 from the home port of Mobile, a service that proved to be a far-sighted move for Wa- terman and one that made an important contribution to the company's growth. During the period of 1946-1948 Waterman owned 55 vessels, comprising the largest dry-cargo fleet in the
American merchant marine.
In 1965 the Walsh family pur- chased Waterman from McLean
Industries, Inc. and formed Wa- terman Industries, Inc. Waterman
Steamship Corporation is now headquartered in New York, with branch offices in Washington, Mo- bile, Houston, Chicago, San Fran- cisco, Dallas, and New Orleans.
Currently, its fleet consists of eight ships — six LASH vessels and two freighters—offering fast and efficient service to the Far
East and Middle East from U.S.
Gulf and East Coast ports. 62 Maritime Reporter/Engineering News
