Electric Boat Awarded $12.1 -Million Increase For

Trident Design Services

General Dynamics Corporation,

Electric Boat Division, Groton,

Conn., has been awarded a $12,100,000 face value increase to a previously awarded cost-plus- fixed-fee contract for the Design

Agent Services (DAS) for Trident

II (D5) capable Ohio class subma- rines. The Naval Sea Systems

Command, Washington, D.C., is the contracting activity.

Mueller Steam Specialty

Introduces Basket Strainer — Literature Available

Mueller Steam Specialty has lit- erature available on its new easy- open basket strainer. It is de- signed to provide maximum straining protection for costly pipe line equipment and at the same time for quick, easy servicing. The quick-opening cover is secured with non-yoke type knobs. The cover and basket are O-ring sealed to minimize gasket replacement and service time. The basket O-ring seal also prevents particle bypass so that the strainers can trap par- ticles as small as 5 microns when the appropriate wire mesh lining is specified.

Mueller Steam Specialty basket strainers are available from stock in cast iron, carbon steel, stainless steel and bronze. Standard basket material is stainless steel. Special materials, baskets and coatings are available on request.

SSC-315, "Fatigue Considera- tions in View of Measured Load

Spectra," documents experimental work, including data analysis, used in assessing the characteristics of fatigue crack propagation under load spectra typical of those expe- rienced by ships at sea. Such infor- mation was obtained from the

SL-7 containership instrumentation program. Results of these random loadings are compared with con- stant amplitude loadings.

SSC-316, "Ship Structure Com- mittee Long Range Research Plan," outlines the research needed be- tween now and the year 2000 to be prepared to meet the demands on the marine industry by that time.

A listing of necessary project areas is included.

SSC-318, "Fatigue Characteri- zation of Fabricated Ship Details for Design," presents a fatigue de- sign procedure for ship details that should help to eliminate cracks in details. It is an important part of the Ship Structure Committee's overall program to provide infor- mation on sound and economical details for ship structures.

SSC-320, "A Study of Extreme

Waves and their effects on Ship

Structures." This report repre- sents one of the technical commu- nity's earliest efforts to describe, quantify, catalogue and assess the characteristics of extreme waves.

It is intended that future efforts in this area will focus on recreating the various types of extreme waves in model tanks in order that each ship design could be evaluated for its own response. "Ship Structure Committee Pub- lications—A Special Bibliography."

This report documents the reports published by the Ship Structure

Committee through 1981 and gives a brief description of each.

SSC-317 and SSC-319 will be pub- lished at a later date.
