Ship Structure Committee Publishes II

And Underwater Repair Procedures

The Ship Structure Committee has recently issued two new reports on the following topics:

Reduction of S-N Curves for Ship Structural

Details, and Underwater Repair Procedures for

Ship Hulls (Fatigue and Ductility of Underwater

Wet Welds). Report SSC-369 "Reduction of S-N

Curves for Ship Structural Details" presents a set of fatigue S-N curves for design and analysis of ship structural details. The set of fatigue curves is based on a re-analysis of fatigue data presented in the Committee's SSC-318 report.

SWATH Intl. Appoints Managing

Director, Unveils New Design

SWATH International Ltd. has appointed

Capt. C. William Hayes the company's manag- ing director. Capt. Hayes replaces Timothy A.

Kelley, who recently resigned as chairman and managing director of the company. Capt. Hayes has been marketing director for SWATH Inter- national since joining the company in 1990.

SWATH has also unveiled a brand new de- sign, their Channel Class 61.3-ft. (19-m) shore to cruise ship tender. To be constructed of alumi- num, the vessel would have a small waterplane area twin hull form, and is designed to achieve

The methodology used to develop the fatigue S-

N curves is presented. Examples are presented to illustrate the application of S-N curves for plating under one-inch thick. A glossary of terms used is provided and recommendations are presented for future research. Report SSC- 370 details the use of underwater welding for the repair of damage below the waterline of a ship or marine structure. These procedures have devel- oped greatly in recent years. However, these procedures have generally only been acceptable exceptional ride quality while sustaining service speed even in a degraded seaway. Passenger cabin area will accommodate 100 passengers.

The beam of the vessel is 24.9 ft. (7.6 m) with a full load draft of 5.2 ft. (1.6 m). The vessel will attain a speed of 22 knots.

Gaming Council To Sponsor

St. Louis Meeting

A special two-day conference planned for May 23-24, 1994 will be sponsored by the Gaming

Cruise Council of the Passenger Vessel Associa- tion (PVA). The meeting will be held at the Regal

Hotel in St. Louis, Mo., and will bring together as emergency repairs and temporary. Uncertain- ties with regard to the long term properties of the repairs have prevented a greater acceptance.

This report addresses specifically the fatigue performance and low tensile elongation proper- ties of underwater wet weld repair methods. The report concludes with recommendations for fu- ture research. These reports, and any other SSC report, may be ordered from National Technical

Information Service, Springfield, Va. 22151, tel: (703) 487-4650; fax: (703) 321-8547.

Among the sessions planned are: Introduction to Maritime Safety Regulation: How the System

Works',Developing Safety Awareness Within Your

Company, Marine Crew: The Key to Reducing

Liability; Marine Insurance Underwriting Li- ability-Preparing Emergency Disaster Programs;

Making Safety Codes Work for You; and Crime and Casino Vessels — Minimizing the Impact on the Local Community.

Introducing the Dock Fendering System from BFGoodrich — complete with the proven protection of LINERITE® and Solidur.

Custom-designed for high-impact areas, LINERITE is an engineered composite of polymer and rubber layers that absorb and withstand repeated blows. Protecting far longer than traditional wood, tires and other fendering materials.

Solidur, a solid UHMWP material, rounds out the BFG system — reducing friction and wear while providing impact strength. For pier and canal walls, it's the premier polymer facing.

For more information on our new, environmentally friendly Dock

Fendering System, call 910-251-8000. Or fax 1-800-835-2575. And get long-lasting, low-maintenance protection that saves you money.

Now isn't that a nice twist.
