moving the aft part hull, comprising the engine room and Hold No. 7, in the direction of the slipway's front for a length of 11.8 feet. Construc- tion of the hull was in two parts — engine room and one part of Hold

No. 7, and the other part from Hold

No. 4 forward to the bow. The dis- tance between the two parts was about 8.2 feet.

Both parts of the hull were sup- ported, as usual, by sand-filled blocks. The aft part, in anticipation of the eventual sliding-down opera- tion, was set 120 mm higher than the bow part. After completion of the aft hull and the usual extent of engine room outfitting, prepara- tions began for the sliding-down op- eration.

By use of steel wire ropes the aft hull was secured to the Goliath Gan- try Crane that spans two slipways.

By employing constant force from the gantry, tbe aft part was guided down the sliding ways at a constant speed of just under 2 feet per min- ute for the total distance of 114.8 feet. The aft hull was stopped by effecting increased force from the gantry. After having been stopped, the aft hull was accurately posi- tioned longitudinally and trans- versely by means of hydraulic presses, and then lowered by letting the sand flow out of the supporting blocks.

The complete operation, includ- ing sliding down, accurate position- ing, and lowering of the hull part was carried out during two working days. A section containing Holds

No. 5 and 6 was then inserted between the aft hull and the bow part.

When completed, Hull No. 643 will have an overall length of 728.7 feet, beam of 75.7 feet, depth of 48.4 feet, and draft of 26/31.8 feet.

Isotta Fraschini Receives

Order For 8 Engines —Literature Available

The Yugoslavian company Brodo- materijal of Fiume has placed an order with Isotta Fraschini for eight

ID 36 SS 8V diesel engines that will be used to power ferry boats. The

Italian company's 6-16 cylinder, V- configuration ID 36 series engines have been adopted by several for- eign countries (U.S., Great Britain,

Greece, Yugoslavia and Norway) for a variety of commercial and military applications.

System' Now Available

The Maritime Administration has announced the publication of a two- volume research report, "Ship Per- formance Analysis System (SPAN)."

May, 1986

The report describes the develop- ment of a microcomputer software program for determining the best hull and propeller surface vessel. It operates on an IBM-PC/XT or com- patible computer.

The study team was headed by

John J. McMullen Associates, Inc.

Also participating were two U.S.- flag vessel operators, Titan Naviga- tion, Inc. and Tanker Management,

Inc., and two marine coatings manu- facturers—Devoe Marine Coatings

Co. and International Paint Co.

McMullen was responsible for managing the project and develop- ing and documenting the SPAN sys- tem. The ship operators and paint manufacturers assisted in the devel- opment of data.

The system analyses factors af- fecting ship performance and com- bines this with a financial analysis to evaluate alternative hull coating systems and propeller cleaning strategies.

Copies of the report may be ob- tained from the National Technical

Information Service, 5285 Port

Royal Road, Springfield, Va. 22161.

The order numbers and prices are as follows: Executive Summary,

PB86-169554/AS, $9.95; User's

Manual, PB86-169562/AS, $22.95.

SPAN computer programs are available on diskettes from J.J.

McMullen. For information on how to order,
