Tokimec is the new name for
Tokyo Keiki, a leading Japanese company in composite sensing tech- nology. For almost a century the marine systems division of Tokimec has developed new and innovative products for commercial, luxury, lei- sure and fishing craft. Tokimec offers marine radars, gyrocom- passes, autopilots, GPS navigators and RASCAR radar systems.
Tokimec's BR-1800 series rasterscan radars have automatic tuning and sea clutter suppression to provide simple operation. A newly developed MIC for the front-end of the receiver helps to keep a lower signal-to-noise ratio. IMO versions are available with a Gyro/Log inter- face unit and a passive type performance monitor.
Some of the gyrocompasses pro- duced by Tokimec are the ES-series, the GM-20/2 land the TG-5000. The
ES-series includes Type ES-10 which uses the master compass directly in steering without using repeaters and
Type ES-11A which uses repeater compasses. This type of gyrocom- pass has been installed on over 20,000 different vessels since it came on the market.
The GM-20/21 is one of the world's smallest gyrocompasses featuring a syncro output, which can be used to drive the Tokimec PR-1000 steering control. The GM 20/21 is made up of a master compass which is ideal for operators of small commercial ves- sels and fishing boats due to space limitations.
The TG-5000 gyrocompass is pri- marily for medium to large ship installations and conforms to IMO standards. The master compass and a transmission box make up this unit. It is reported to be easy to operate since there is only one con- trol switch and speed error is automatically corrected. This se- ries also offers other desirable features such as emergency back-up functions and an extensive repeater circuit.
The Tokimec PR-8000 autopilot conforms with the recommendations of SOLAS, the IMO, and the rules and regulations of many countries and classification societies. Each unit can be customized to fit aboard a particular vessel with its func- tional units mounted either into the stand-alone system or into console and cockpit configurations. The unit provides two steering modes which are the adaptive mode, which uses the Model Reference Adaptive Con- trol System (MRACS), and the PID mode which enhances the stability and accuracy of course functions through a new control system.
The GR-1000 GPS navigator has a continuous fix mode with a mul- tichannel receiver that can give complete position fixing. The dis- play gives navigational as well as simple plot functions. The unit also gives various types of navigational data such as waypoint and time to go to a destination. Any desired route can be set and changed with a print out of the information if de- sired.
The RASCAR radar system has touch-screen capabilities which eliminate the need for additional buttons and knobs. The radar offers a variety of features as well as many optional functions to make opera- tion easier.

Jeffboat To Build 10 Tank Barges For Mobil
Jeffboat, Inc., Jefferson ville, Ind., has begun construction of ten 240- foot double-hull tank barges for
Mobil Corporation, Fairfax, Va. The construction contract is valued at about $10 million.
To be used on the Mississippi
River and inland waterways for the transportation of crude and oil prod- ucts, the tank barges will have a beam of 54 feet and draft of 9-1/2 feet. The barges will be fitted with the latest vapor recovery and inert gas systems, cargo gaging and level monitoring and alarm equipment.
The vessels will replace single-skin barges currently being operated by the Marine Transportation Division of Mobil. The new double-skin barges are expected to be delivered and in operation by the end of this year.
Mobil's Marine Transportation
Division moves over 100 million bar- rels of crude oil and other products in the inland and coastal waters of the U.S.

Installed On Trawler
The 1000th Schottel transverse thruster will be installed into the bow of a trawler at the ASENAV yard in Chile. The STT-170 LKT thruster is rated at 184 kw at 1,470 rpm. The trawler will also receive a second Schottel transverse thrust- er, an STT-330 LKT, in its stern.
Schottel is one of the world's lead- ing manufacturers of azimuthing propulsion units and maneuvering aids, with its transverse thrusters covering a power range from 30 to 1,650 kw. Units rated at 500 kw or higher are available with either fixed-pitch or controllable-pitch pro- pellers.
Introduced in the 1960's, the
Schottel transverse thruster have been operating successfully world- wide in vessels of varying sizes and types. The Schottel pressure-equal- izing tunnel, known since 1970 as the Anti-Suction-Tunnel, or AST, was also a major improvement to vessel maneuverability.
