TECHNICAL PAPERS Thursday, November 10 Trianon Ballroom 9 a.m.—Seakeeping and Extreme Tensions in Offshore Towing," by Jerome H. Milgram, Michael S. Triantafyllou, Fernando C. Frimm and George Anagnostou.

A 12-degree-of-freedom seakeeping theory is developed and used for a tug, tow and towline in the open ocean. Statistics of nonlinear extreme tensions are determined and used. The principal non-linearity is due to mechanics of the towline.

Examples are presented showing how speed and towline length can be adjusted to limit towline damage risk.

10:30 a.m.—"Measurement of Ship Resistance, Powering and Maneuvering Coefficients from Simple Trials During a Regular Voyage," by M a r t i n A. A b k o w i t z and Gengshen Liu.

Data obtained by ship instrumentation from a few simple trials of the 75,000-dwt Exxon Philadelphia dur- ing a routine voyage was analyzed using system identification techniques.

This resulted in a reliable "measurement" of the full scale resistance, wake friction, thrust deduction factor, propeller thrust and the linear and nonlinear coefficients in the maneuvering equations of motion. Comparison between these full-scale measurements and those obtained through scaled model tests indicate significant scale effect.

3 p.m.—"The Building and Operation of Vibration-Free and Trouble- Free Propulsion Plants and Ships," by G.C. Volcy, M. Baudin and C. Guinard.

Over the last 30 years, a tremendous growth in problems with propulsion plant seizures, often accompanied by steel-work and machinery troubles, has been linked to incompatibility between ship structure flexibility and stiffness of lineshaftings manifested by forced vibrations.

Simultaneous treatments of static and vibratory phenomena by use of 3-D FEM calculations has eliminated these difficulties. Several examples are presented.

Mercury Ballroom 9 a.m.—"Flexural Response of Foam-Cored FRP Sandwich Panels,' by Deborah Weissman- Berman, George L. Petrie and Mo-Hwa Wang.

The flexural response of an FRP foam-cored sandwich beam is predicted using two new closed form solutions and a finite element model.

The comparative results are very good for all predictive methods for thick-skinned composites and all have excellent correlation to test data for both "linear" and crosslinked" sandwich-core materials.

Therefore, the methods given in this paper will work well for composite structural analysis.

10:30 a.m.—"Statistical Analysis of Stillwater Load Effects in Ship Structures," by C. Guedes Soares and T. Moan.

Collecting data from the voyages of 100 vessels, this paper performs a statistical analysis of S t i l l w a t er bending moment and shear forces to establish the variations of the maximum stillwater load effects that occur during operation of oceangoing ships. Identifying the effects of vessel size, type, and loading condition in addition to providing summary statitics, regression equations are proposed along with considerations due to longitudinal distribution of vessel load.

3 p.m.—"Potential Failure of Surface Ship and Submarine Drydock Blocking Systems Due to Seismic Loadings and Recommended Design Improvements," by Richard D. Hepburn, James K.

Luchs Jr., Dale G. Karr and Ross L. Haith.

Many naval shipyards are located in regions where significant earthquakes occur. A method for analyzing the dynamic response of submarine drydock blocking systems is developed. Eleven systems are assessed for various failure modes using two site specific earthquake acceleration histories. Design improvements are recommended to significantly increase the survivability of submarine blocking systems subjected to earthquake ground motion.

Friday, November 11 Trianon Ballroom 9 a.m.—"Structural Analysis of the U.S. Coast Guard Island Class Patrol Boat," by Edward S. Purcell, Stephen J. Allen and Richard T. Walker.

The U.S. Coast Guard recently deployed several 110-foot patrol boats of the Island Class. A structural analysis of the bottom plating of the vessel was conducted, including traditional calculations, finite element modeling, reliability analysis, tank testing, field testing and pressure calculations. Recommendations for structural improvements are made and data processing techniques are discussed.

10:30 a.m.—"A Procedure for the Structural Design of Icebreakers and Other Ships Navigating in Ice," by John C. Daidola and Rubin Sheinberg.

Reflecting the rising worldwide interest in icebreaking, this paper puts forth an original approach to the design of such vessels. Applying environmental and operational loads and the analysis of structural response, the procedure has considerable potential for structural weight savings. Additionally, an extensive reference list is included as well as comparisons to existing vessels and codes.

2:30 p.m.—"Prediction and Measurement of the Performance of Free-Flooding Ship Antirolling Tanks," by William C. Webster, John F. Dalzell and Roderick A.

Barr.

During the 1986-1987 CV-41 Motions Improvement Program, passive antirolling tanks were considered for ship roll motions reduction.

Ship arrangements dictated the use of free-flooding type tanks with water "cross-over" external to the ship. This presentation addresses the primary problems faced in the engineering assessment of such tanks, the lack of quantitative performance data and of methods of predicting tank performance and tank impact on ship resistance.

Mercury Ballroom 9 a.m.—"New Models for Minimal Time Ship Weather Routing," by Anastassios Perakis and Nikiforos Papadakis.

Three models for minimal time ship weather routing are presented, for stationary, time-dependent (but known) and probabilistic weather conditions, respectively. These models allow for prohibited sailing regions (land or other constraints), intermediate destinations with time delays, and updated weather infomration (for the probabilistic case).

Mathematical techniques from the calculus of variations, dynamic programming and optimal control are used.

1 0 : 3 0 a.m.— " P e r f o r m a n ce Analysis of a Small Racing Boat in Smooth Water and its Design Application," by Atsuo Yazaki, Suketou Wakamatsu, Tetsuo Tagori, Michio Nakato, Hiroharu Kato, Hiaku Tanaka and Mitsuhiro Abe.

2:30 p.m.—"The Reconstruction of SS Matsonia: Trailership to a Combination Container and RO/RO Ship," by Ronald F. Briggs, Christopher T. Clement and Peter A. Fisher.

Originally designed as a pure trailership, the Matsonia was reconstructed as a combination container- RO/RO vessel to suit the West Coast-Hawaii trade, entering service in late 1987. This presentation traces the economic analysis, design evolution, reconstruction system, equipment reactivation and early operational experience of the ship and discusses many of its unique features.
