Technical Papers (See table for time and location.) Paper No. 1—"A Bulbous Bow Design Methodology for High- Speed Ships," by Jeff W. Hoyle, Bill H. Cheng, Bruce Hays, Bruce Johnson, and Bruce Nehrling.

ABSTRACT—A series of bulb forms is developed and analyzed us- ing a combined numerical and experimental approach to ascertain resistance and seakeeping characteristics.

Using the FFG-7 Class of naval frigates as the reference hull form, nine variations in bulb design plus the bulbless hull form were analyzed by the DTNSRDC's XYZ Free Surface Program. Five of the bulb variations were tested in the U.S. Naval Academy's Towing Tank. The results from the computer predictions and the tank tests show remarkably similar trends, and the relative ranking of the bulb forms were identical. Furthermore, the addition of a bulbous bow to the FFG-7 hull form appeared to only marginally degrade the ship's seakeeping characteristics.

Paper No. 2—"The MV Arctic: New Bow Form and Model Testing," by David Baker and Roy Nishizaki.

ABSTRACT—The icebreaking cargo ship MV Arctic has recently been upgraded for fitting a new bow form. This paper describes the history, development, and extensive model test series that resulted in the new "Melville Bow" that has now been fitted to the ship. The results of the ice model tests, conducted in three different ice tanks, are compared and correlation problems discussed.

Paper No. 3—"Analysis and Design of Steering System Components for Arctic Class Ships," by Balji C. Menon, Ian F. Glen, and Ian M. Bayly.

ABSTRACT—Measured torque in the rudder stock resulting from rudder ice impacts during dedicated trials of three icebreaking vessels are presented. Vessel operational modes and the ice environment contributing to the recorded strains are discussed. Flexural strains in rudder stock resulting from rudder ice impacts on typical rudder arrangements of icebreakers are shown to be small in comparison with the torsional strains. This supports the experience that the major mode of steering system failure is associated with twisting of the rudder stock.

Paper No. 4—"A Study of Shiphandling Performance in Restricted Water: Development and Validation of Computer Simulation Model," by Haruzo Eda, Peter K. Shizume, John S. Case, and Joseph J.

Puglisi.

ABSTRACT—Efforts have been made to develop realistic modelings of ship dynamic motions with emphasis on the case of restricted water under various projects such as Panama Canal Improvement Program.

This paper presents major examples of development and validation studies, together with certain applications results. Actual data collection of model tests and ship trials were adapted for use in the computer model development.

Paper No. 5—"Developments in the Design of Oceanographic Ships," by John C. Daidola and James J. Griffin.

ABSTRACT—Developments in the design of oceanographic ships are reviewed in the time period from 1970 to the present, and possible future near-term developments are considered as well. A synopsis of recent oceanographic vessel construction, and user or scientific requirements for oceanographic ships are presented. General-purpose, geological, geophysical, and fisheries vessels are described.

Paper No. 6—"Liquid Sloshing in Slack Ship Tanks: Theory, Observations, and Experiments," by N.A. Hamlin, Y.K. Lou, W.M.

Maclean, F. Seibold, and L.M.

Chandras.

ABSTRACT—Sloshing waves in partially filled oscillating rectangular tanks are shown to agree well when determined experimentally, and by analysis using a nonlinear theory for smooth tanks, and a numerical simulation technique for tanks with two-dimensional obstacles.

Cases of shipboard sloshing damage are cited. Model tests are given for sloshing forces on structural members, and sloshing pressures, in ship-like tanks with internal structure.

Paper No. 7—"Research Plan for the Investigation of Dynamic Instability of Small High-Speed Craft," by Steven H. Cohen and Donald L. Blount.

ABSTRACT—Small high-speed craft have been known to lose stability while under way even though they possess adequate stability at rest. Unstable conditions can include rapid loss in running trim, progressive heeling, or sudden combined roll-yaw motion. The prirriary objectives of this paper are to focus attention on this little-understood problem, describe recent developments, and present a long-range research plan.

Paper No. 8—"Time-Simulation of Ship Motions: A Guide to the Factors Degrading Dynamic Stability," by N.M. Elsimillawy and N.S. Miller.

ABSTRACT—A time-domain numerical simulation of the ship motions in regular sinusoidal waves in six degrees of freedom has been used to discover the dangerous situations that may lead a ship to capsize.

An investigation into the dynamic stability of the trawler Gaul, which disappeared in heavy seas in 1974, is used as a demonstration.

The basic approach of the simulation program involves the computation of the coefficients of the equations of motion at each step in time according to the exact wave and vessel position using strip theory.

Paper No. 9—"Ocean Drilling Program Equipment Capabilities," by Dillard S. Hammett.

ABSTRACT—This paper introduced new technology that extends the capability of drilling in 15,000- foot water depth for the purpose of gathering Earth Science data. The application of the petroleum industry experience to drill in these water depths has led to a successful first year of operation of the Ocean Drilling Program (ODP). The technology exchange between the scientists and drilling industry is a key part of the 14-year program. In addition to Earth Science, this program will provide data for future energy sources. The ODP has the potential to provide more useful data for mankind's life on earth than the space program has produced.

Paper No. 10—"Validation of Fatigue Life Prediction Using Containership Hatch-Corner Strain Measurements," by Yung-Kuang Chen, Jeng-Wen Chiou, and Anil Kumar Thayamballi.

ABSTRACT—Using measured strain data and recorded service experience related to fatigue cracking at a containership's hatch corner, the validity of various fatigue life prediction methodologies is evaluated.

The correlation study considers deterministic S-N curve approach, probabilistic calculations of fatigue damage, and fracture mechanics assessments. Description of local cracking experienced, characteristics of the strain data measured, and the various analyses performed are presented.

Paper No. 11—"Governing Ship Propulsion Gas Turbine Engines," by C.J. Rubis and T.R.

Harper.

ABSTRACT—This paper presents the results of analytical studies, computer simulations, and ships' trials in the investigation of the propeller loading mechanism, propulsion system cycling, and propulsion system response to speed and power governing in a seaway and under various ship maneuvers.

Performance and design criteria for governing systems are discussed.

This is a companion paper to two earlier (1972,1982) SNAME Annual Meeting papers describing results of the Naval Gas Turbine Ship Propulsion Dynamics and Control Systems R&D Program.

Paper No. 12—"A Computer System Architecture for Naval Ship Design, Construction, and Service Life Support," by Daniel W. Billingsley and J. Christopher (Kit) Ryan.

ABSTRACT—The computerbased "product model" is identified as the most important technical product of computer applications to ship design, construction, and service life support. The architecture of the Navy's Computer Supported Design (CSD) System, which supports product model development during the design process, is described along with the applicability of the architecture to ship construction and service life support functions.

The key role of the product model in the digital data transfer process is highlighted.

Paper No. 13—"Model and Full-Scale Tests with an Innovative Icebreaker Bow," by E. Enkvist and E. Mustamaki.

ABSTRACT—Unconventional bow forms have been introduced to break thick level ice in Siberian rivers.

In this paper some rounded and squared types are compared using model test results. An interesting bow candidate was full-scale tested using a 300-ton separate bow suspended from a tug. Conclusions are drawn as to advantages and drawbacks for the new bow, which is not intended for universal use on icebreaking ships.
