Derecktor Shipyard Lays

Keel For First Of Two

Tugboats For U.S. Army "Laying-of-the-Keel" ceremonies for the first of two 128-foot tugboats for the U.S. Army took place recent- ly at Derecktor Shipyard in Middle- town, R.I. The ceremony designates the achievement of a major mile- stone in the planned scheduled con- struction of the vessel.

The U.S. Army Large Tug's (LT) design offers operational and sur- vival capabilities to meet firefight- ing, salvage, rescue assistance, ship docking, and barge-handling mis- sions. Inherent features of the LT will provide a high level of maneu- verability, superb seaworthiness and optimum efficiency.

The first tugboat, known at the present time as Hull 130A, is sched- uled for delivery in July 1989. The tugboats will be named after signers of the U.S. Constitution. The con- tract could extend for the construc- tion of a total of 10 tugboats if all funding is released to the program.

Wartsila Diesel Presents

Paper At ASTM Symposium

Wartsila Diesel recently pre- sented a paper entitled "Fuel Oil

Characteristics That Are Consid- ered Most Important For Modern

Marine Diesel Engine Operation

And Development" at the ASTM

Marine Fuels Symposium held at the Hyatt Regency Hotel in Orlan- do, Fla.

The paper, authored by Karl

Yannes of Wartsila Diesel, Inc.,

Greenwich, Conn., explains how

Wartsila Diesel first approached the problems of burning today's residu- al fuels by designing their diesel engines from the very beginning to cope with poor quality marine fuels over the entire load range from start to stop. As a result of this modern development program and the prov- en operation of this advanced de- sign, most of the characteristics of residual marine fuel oils that were generally considered important are no longer of importance to the fu- ture development of the Wartsila vasa engine types.

The paper goes on to explain how and why fuel oil characteristics, such as aromaticity, will increase in important for modern diesel engine operation and development and what design techniques can be uti- lized to overcome the problems that may be encountered both now and in the future.

A copy of the paper is available upon request. For your free copy,

Aeroquip Introduces

Reusable Fittings For

Convoluted Teflon Hose —Literature Available

A leading manufacturer of reus- able fittings for over 45 years, Aero- quip is now introducing reusable fit- tings for Aeroquip convoluted Te- flon™ hose, ideal for tough chemical processing and fluid transfer appli- cations.

The reusable fitting features a three-piece, bolt-together stainless steel socket and Aeroquip's paten- ted lead-in nipple which screws into the convolutions of the Teflon tube.

Nipples are available in carbon steel or stainless steel, with complete fit- tings available in sizes -16 (1-inch) and -32 (2-inch) sizes.

Aeroquip reusable fittings can save up to 70 percent on the cost of replacement hose lines. When fit- ting replacement is necessary, the fittings which are on the equipment and matching bulk hose provide the ability to make any needed hose line. Hose assemblies can be made on the job using a simple Allen wrench.

Detailed information, including assembly instructions, on Aero- quip's convoluted Teflon hose can be found in Bulletin IEB-319. For a free copy,
