Raytheon Building $1.4-Million Magnetic

Measuring System For USN

Work is under way at Raytheon

Company on a U.S. Navy system that will measure magnetic fields of ships before and after their hulls have been treated for de- fense against magnetically influ- enced mines. The automated sys- tem, which includes underwater magnetic sensors and data proc- essing and display equipment, has been designed and will be built by

Raytheon's Submarine Signal Di- vision, Portsmouth, R.I., for in- stallation at the U.S. Navy De- perming Facility in San Diego.

The facility will accommodate vessels up to 30 feet in draft.

The $1.4-million contract with the Naval Sea Systems Command follows recent delivery by the

Raytheon division of computer- controlled systems for both the measurement and treatment ranges at the Navy's Magnetic

Silencing Facility in Bangor,

Wash. As systems prime contrac- tor, the division is also responsi- ble for the current installation of sensors and shore-based instru- ments for these ranges, which will greatly reduce the processing time for a ship's treatment. $61-Million Navy Award

To Tacoma Boat For

T-AGOS Construction

Tacoma Boat Building Compa- ny, Inc., Tacoma, Wash., has been awarded a $61,195,450 modifica- tion to a previously awarded con- tract for construction of T-AGOS vessels for the second program year (FY 81). The Naval Sea

Systems Command is the con- tracting activity (N00024-80-C- 2046)

Designer's Handbook From

National Marine Service

Describes Firm's Products

National Marine Service has made available a Designer's

Handbook for naval architects, vessel operators, and shipyards.

The new handbook includes tech- nical literature and specification data for National Marine lines of marine instrumentation, bilge management systems, alarm sys- tems, and safety watch and con- trol systems that are customized to each vessel.

The new master clock, auto- matic bell logger, scanning tem- perature pyrometer, analog tach- ometer, and clutch slip panel are fully described. A chapter of the handbook covers American Bu- reau of Shipping (ACC and AC-

CU) and USCG regulations (NVC 1-78 and NVC 1-69) as they per- tain to reduced manning and Na- tional Marine's instrumentation.

Awarded To Nationwide

Boiler Rentals

Nationwide Boiler Rentals, Inc.,

Mountain View, Calif., has been awarded a $1.9-million contract by the U.S. Navy to design and construct seven mobile boiler rooms. The systems, each con- sisting of two 5,000-pound-per- hour, 200-psi boilers, contain com- plete water-softening equipment, chemical feed systems, and fully automatic controls. Primary use of the systems will be to provide steam for electrical generators as well as hotel and other ships comfort services during extended, in-port stays and during sched- uled boiler maintenance periods.

According to Richard Bliss, president of Nationwide, "The concept of using smaller mobile boilers to provide ships services while in port for extended stays is far more energy-efficient than keeping the large onboard boilers operating." The contract calls for acceptance and delivery of the first unit within 12 months, with the remaining six units to be de- livered during the following year.

The firm produced two similar systems for the Navy in 1978.

Michigan-Jastram... new worlds of maneuverability.

Michigan'

Modern ways to move your ship

Michigan-)astram gear case as installed.

As a professional, you know that speed, efficiency and maneuverability are increasingly important to your profitability. That's why —when it comes to making the right move — you should run with Michigan-Jastram Bow Thrusters.

Michigan-Jastram combines Michigan

Wheel's experience in design and manufacturing of propellers and nozzle systems with the ex- perience in design and manufacturing of right angle gears and thrusters of Jastram-Werke of Hamburg,

Germany. The result...the latest designs of propulsion and maneuvering equipment in

North America today.

Michigan-Jastram Bow

Thrusters are your modern means of improving maneuvering capabilities in ships of all sizes and types.

By generating transverse thrust, the vessel achieves the ultimate manageability. Especially at slow speed, when the main rudder ceases to respond, the ship can still maintain control. What that means for you is... improved maneuvering capability, substantial saving of tugboat charges, reduced risk of collision and increased safety at low visibility.

Michigan-Jastram Bow Thrusters are usually delivered with full length high quality tunnels for lower material cost and ease of installation. Once installed in the vessel hull, simply connect the system to your engine. In its standard form the bow thruster gear and propeller can be removed through the tunnel.

Michigan-Jastram, a part of Michigan's new

Michigan Propulsion Systems

Group, is playing a major role in the development of t^siBPI Michigan" maneuvering techniques. 1 JH I

Their wide experience and I ij^B I all customer staff of qualified employees I ^Hl I requirements, have made Michigan-

Jastram a specialist in the field of maneuvering technology.
