Marine Jet Drives (continued from page 45) years into business, North American has Nomera 20 modified units in- stalled in the Canadian Forces Bridge Erection Combat support boats, with additional vessels pro- jected. Units are also specified for boats being built in Korea, Japan, Thailand and for South America. Experience of the long term and varied nature forms the manage- ment team for North American. Complementing Mr. Hill's strong marine jet background is Jack Seastrom. Mr. Seastrom has a background ranging from retail dealer through boat manufacturing at Kenner Boat Co., Marine Jet at Jacuzzi and operations with Off- shore Logistics. His marine design skills are important to the engineer- ing applications information needed by many North American Marine Jet customers. ANNOUNCING... Combustion Engineering, Inc. and Murray Tube Works Inc., Boiler Tube Company of America and Senior Engineering Group pic. are pleased to announce that they have amicably resolved the disputes involved in Civil Action No. 1-83-577 in the United States District Court for the Eastern District of Tennessee, Southern Division, at Chattanooga, Tennessee. By the terms of a settlement agreement, Combus- tion has granted to Murray Tube, Boiler Tube, and Senior Engineering Group the rights to receive Combustion proprietary engineering drawings from owners of Combustion fossil-fueled boilers and to use certain drawings for the manufacture and fabrication of boiler replacement parts, for an initial period of ten (10) years. Combustion will be paid a mutually agreed consideration for the addi- tional benefits the companies have received. The agreement extends to all drawings now in the possession of Murray Tube and Boiler Tube, as well as to the drawings furnished to them by Combustion boiler owners during the term of the agreement.

Exam- ples of success with proper applica- tions include the U.S. Navy P.B.R. Program. Over 500 vessels were pro- duced for the Navy since the late 1960's. This vessel is still opera- tional throughout the U.S., Asia, the Mideast and in the South Americas. It is believed 80% of the vessels are still in service, some of them over 15 years old. Additionally, several countries are building new vessels from the old design. One highly successful commercial operation is a fleet of 5 triple 20Y powered crew boats operating in the South China Sea. Mr. Seastrom was operations manager there and can cite figures indicating 100% uti- lization over periods longer than a year. Crossing a shallow river bar several times a day, the crewboats performed at speeds equal to the twin screw crewboats which were restricted to a deep water port 100 miles away. According to Mr. Sea- strom the boats ran every day, kept well within maintenance allowances and operations records indicated costs (overall) were comparable to twin screw 80's Mr. Seastrom also managed. The Navy has a fleet of little pub- licized armored personnel vessels. There are several timber companies using jets, the company also works with the Corps of Engineers, fire departments in Portland and New Orleans, service contractors on the Mississippi river; and many other operators. Future plans include a new gener- ation patrol boat, new water propul- sion drives, and new markets in water areas worldwide where shal- low draft, freedom from debris dam- age, operation at low tide and lack of drydock facilities are a considera- tion. The use of jets eliminates, from the flywheel back, the gearbox, pro- peller shaft, strut, propeller, rudder and related hardware. This effec- tively eliminates costs associated with any damage to this hardware and downtime resulting from opera- tions in shallow or debris prone areas. The company reports, on the Nomera 20, the cost of the jet drive unit itself is a trade-off against elim- inated hardware. The ability to op- erate in previously inaccessible areas, the opportunities for time/ cost saving shallow area operations and the elimination of downtime are pluses.
