SNAME Spring Meeting & Star Symposium (continued from page 44)

Paper No. 11—"Control and Guidance . . .",

Hoffman/Armen.

Synopsis — A fundamental of the seagoing experience is the interplay between environ- mental excitation (wind and wave), dynam- ics/response of the affected vessel, resulting loads, and ultimate structural integrity. Re- cent advances in environmental loading pre- dictive techniques have led to more rational answers to the inherent safety problems.

Conventional shipping draws on an experi- ence bank, but assuring adequate safety in the newer, less orthodox floating structures under limiting weather conditions presents a significant challenge.

Paper No. 12—"Life Safety Approach . . .",

Decarteret/Lemley/Sheehan.

Synopsis — The life safety risks that fisher- men face are many and varied, as are the designs of the vessels they operate. This paper presents a series of suggested vol- untary practices in the operation, design and construction of fishing vessels that may les- sen the risks. Particular emphasis is placed on fire protection, on lifesaving appliances and on certain practices that could prove beneficial.

Paper No. 13 — "Seakeeping in Ship Oper- ations," Comstock/Bales/Keane.

Synopsis — Four types of seakeeping intelli- gence data systems, Optimum Track Ship

Routing (OTSR), Tactical Operations Ship

Routing (TOSR), Ship Survivability in Ex- treme Weather (SSEW) and Heavy Weather

Operator Guidance (HWOG), can be useful to the operator. This paper focuses on Heavy

Weather Operator Guidance whereby quan- titative information is provided to the oper- ator on the behavior of his ship under a set of arbitrary sea conditions as well as guid- ance on avoiding severe motions.

Paper No. 14—"Influence of Hull Form ...",

Schmitke.

Synopsis—In this paper, the factors with pri- mary influence on ship rolling are studied parametrically using recently developed and validated prediction methods. Factors include hull form, bilge keel and rudder size, meta- centric height, and active stabilization. For each ship configuration, predictions are made for a range of speed and sea conditions. Re- sults are presented in graphical form so that the effect of each parameter on rolling may be readily assessed.

Paper No. 15 — "Extreme Value and Rare

Occurrence Wave Statistics . . .", Cummins/

Bales.

Synopsis — The existing ocean environment data bases, though much improved in recent years, are still inadequate in several re- spects. Sufficient information for the syste- matic, scientific design of new ships or the analysis of operational failures is lacking.

Consequently, in 1975 the U.S. Navy ini- tiated a project to remedy this deficiency by hindcasting and systematically collating available data collected over a 20-year pe- riod. The final product will be a new clima- tology of wind and waves for the Northern

Hemisphere. Some initial results, concen- trating on extreme and rare wave occur- rences, are presented in this paper. The sta- tistics offer substantially improved capabil- ity and are so presented as to facilitate adoption into existing procedures for ana- lyzing performance and structural integrity.

Synopsis—This paper describes the concepts developed by SNAME Panel H-10 (Control- lability) for standardized formats designed to present information on a ship's maneu- vering characteristics and capabilities. The information is intended for the practical use of officers and pilots in handling a particular ship. Proposed data acquisition methods will be presented, together with samples of the anticipated end products. The Panel's pro- posals for standardized maneuvering infor- mation are still in draft form, and the au- thors will welcome comments and criticism thereon.

Paper No. 17 — "Status Report on the Ap- plication of Stress . . .", Chazal/Cojeen/

Lindemann/Maclean.

Synopsis — A number of projects are under- way worldwide, aimed at the development of stress and motion monitoring systems de- signed to assist masters and deck officers in the safe operation of their ships. This paper provides a status report on four such efforts of diverse nature in which the U.S. Coast

Guard is participating. Practical aspects of hardware, data presentation and user skill requirements are also addressed.

Paper No. 18—"Nature of Combustion ...",

Hansen/Baham/Porricelli.

Synopsis — Existing federal, state and mu- nicipal air quality laws are regulations gov- ern emissions from large plants, but there are clear signs that smaller industrial plants will soon be brought under the rules. The lowered limits may well be construed as ap- plying to power plants on ships operating in 10 Maritime Reporter/Engineering News
