Technical Papers (See table for time and location.) Paper No. 1—"Evaluation of the Longitudinal Ultimate Strength of Various Ship Hull Configurat i o n s , " by Lembit M. Kutt, C h r i s t o p h e r M. P i a s z c z y k, Yun-Kuand Chen, and Donald Liu.

SYNOPSIS—The longitudinal ultimate strength of several ship hull configurations is analyzed with the nonlinear finite element method.

Included in each analysis are the effects of buckling, post-buckling, and plasticity, and their proper interaction.

In addition, an extensive treatment of the modeling procedures for nonlinear finite element analysis and a study on the sensitivity of the ultimate strength to variations in several parameters are included.

Paper No. 2—"Strength Evaluation of a Novel Unidirectional Girder System Product Oil Carrier by Reliability Analysis," by Tomi y a s u Okamoto, Tohru Hori, Masuru Tateishi, Sherif M.H.

Rashed, and Shigeru Miwa.

SYNOPSIS—This paper describes the design concept of a newly developed product oil carrier, of which double hulls are stiffened only by longitudinally arranged girders. The structural safety in extreme loads and the redundant strength in damaged conditions are discussed, applying reliability analyses.

Based on these results, the structural system is found to offer more safety than conventional design.

Paper No. 3—"Prediction of the Behavior and Propulsive Performance of Ships with Bulbous Bows in Waves," by Peter Blume and Alfred M. Kracht.

SYNOPSIS—As a result of research programs performed by the Hamburg and Berlin, West Germany, Model Basins, design data are now available for the estimation of the seakeeping qualities of bulbous bow ships. Studies on speed loss under service conditions yielded that bulbous bow ships have almost the same seakeeping qualities as comparable ships without bulbous bows in sea states up to Beaufort 6.

Thus the bulbous bow may be designed with regard to its smoothwater performance only. It is prudent, however, to avoid extremely large bulb bodies.

Paper No. 4—"A Realistic Approach to Semisubmersible Stabilit y , " by D r a c o s V a s s a l o s, G e o r g e Konst a n t o p o u l o s , Chengi Kuo, and Yousri Welaya.

SYNOPSIS—This paper de- scribes the rationale behind the development of practical semisubmersible stability criteria that reflect the current state of the art while maintaining the simplicity of existing regulations. The proposed criteria are based on an energy balance approach and incorporate the effects of wind, waves, and vessel motions.

Practical applications are considered and discussed.

Paper No. 5—"A New Warship Design Strategy—A Perspective," by William H. Garzke Jr. and George Kerr.

SYNOPSIS—This new warship design approach to naval ship design is intended to provide the ability to relate a warship's physical attributes (which will define its cost) to the mission requirements they serve, and to use these relationships in the design, development, and construction of more cost- and combat-effective warships.

Paper No. 6—"Vibration Response on Propulsion-Efficient Container Vessels," by Hans G.

Payer and Iwer Asmussen.

SYNOPSIS—Fairly detailed vibration calculations are required during the design phase in order to effectively avoid vibration problems in propulsion-efficient vessels. Typical calculation results including the forced vibration response are presented in this paper and compared with results from measurements for a 2,000-TEU containership. It is shown that the vibration behavior can be predicted with sufficient accuracy to base design decisions on the results.

Paper No. 7—"Rough Propeller Penalties," by R.L. Townsin, D.S.

Spencer, M. Mosaad, and G. Patience.

SYNOPSIS—The ship operator is offered a standard procedure for measuring blade surface roughness using a stylus instrument of comparator gauges. From the resulting single number Average Propeller Roughness, the power penalty may be calculated simply from a nomograph.

The theoretical basis for the genernomograph is described, including the correlation of the roughness measurements with increments in blade section drag and propeller performance.

Paper No. 8—"Structural Reliability of Marine Diesel Engine Propulsion Shafting Systems," by Efstratios Nikolaidis, Anastassios N. Perakis, and Michael G.

Parsons.

SYNOPSIS—A method for estimating the reliability of diesel propulsion shafting systems is presented, involving probabilistic excitation modeling, first excursion and fatigue failure mode analyses, and estimation of failure probabilities.

In the examples presented, significant criticals that cannot be identified by the traditional deterministic analysis are revealed. High values of the traditional safety factor may not always insure system reliability and safety.

Paper No. 9—"Finite-Element Analysis of Elastohydrodynamic Stern Bearings," by Zissimos P.

Mourelatos and Michael G.

Parsons.

SYNOPSIS—A finite element analysis is performed for a marine shafting system using a hydrodynamic, plastic stern bearing. The analysis consists of three-dimensional analyses of the shafting and the bearing liner, a two-dimensional analysis of the oil film hydrodynamics, and iterative techniques to establish the equilibrium position among the shaft, the oil film, and the anisotropic bearing. Results are in good agreement with available laboratory experiments.

Paper No. 10—"Innovative Naval Designs for North Atlantic Operations," by Colen Kennell, Brian White, and Edward N.

Comstock.

SYNOPSIS—A SWATH ship design and two monohulls designed to carry the same payload are summarized.

The two monohull designs used state-of-the-art, hull-form technology. One monohull included excess volume to achieve seakeeping performance comparable with the SWATH. Seakeeping performance assessments were made for mobility and anti-submarine warfare operations in the upper North Atlantic region.

Paper No. 11—"Analysis of the Structure of the Proposed CCG Polar Class 8 Icebreaker Under Extreme Ice Loads," by I. F. Glen, C.

G. Daly, and G. Tam.

SYNOPSIS —The proposed structure design for a large Polar icebreaker for the Canadian Coast Guard has been analyzed using recent understanding of ice loads on vessels, and analytical models to extrapolate areas far beyond current experience. Local bow strength and hull girder response were examined.

• The study revealed areas for potential improvement in the current regulations.

Paper No. 12—"Dynamic Analysis as a Tool for Open-Sea Mooring System Design," by Michael S.

Triantafyllou, Antoine Bliek, and Hyunkyoung Shin.

SYNOPSIS—Methods to change the performance of mooring lines are outlined, based on an extensive study of the effect of the principal parameters on the dynamic tension of cables. Tables and graphs are provided to estimate the equivalent stiffness and natural frequencies of cables, while examples illustrate the application of the proposed methodology.

Paper No. 13—"Hydro-Numeric Design of SWATH Ships," by Nils Salversen, Christian H.

von Kerczek, Carl A. Scragg, Christopher P. Cressy, and Michael J. Meinhold.

SYNOPSIS—A new computational method for the design of Small Waterplane Area Twin Hull (SWATH) ships is presented. The integrated computer system gener- ates mathematically faired SWATH hull forms, computes the total calm water resistance, minimizes the wave resistance by contouring the lower hulls, and predicts the turbulent boundary layer and the wake into the propeller.
