UPDATE

Trimble Introduces NavGraphic

Loran Track Plotter, And New

Digital Version Of 10X Loran

Trimble Navigation of Sunny- vale, Calif., recently introduced a new product, the NavGraphic loran track plotter, as well as a new digital version of their 10X loran.

The NavGraphic loran plotter enables a navigator to see at a single glance where he is relative to signifi- cant waypoints, hazards, and in- tended course, where he'll be in one hour maintaining current speed and heading, and where he's been. One can choose the appropriate visual (1 mile to 125 miles or the entire route) and a graphics and text screen that can be seen from 15 to 20 feet away.

A convenient waypoint and route library is available for easy data review and retrieval. Waypoints can be named and/or numbered. Sym- bols are also available for quick rec- ognition of types of waypoints and routes. Once the NavGraphic is set up, there is no need to manipulate the unit again, unless you want to make a change or adjust the bright- ness and contrast or reverse out the screen for easy night viewing.

The NavGraphic is easy to install, easy to support, and easy to expand with simple plug-ins to other on- board instrumentation.

The new digital 10X loran from

Trimble was developed specifically to address the problem of dealing

NavGraphic loran track plotter. with environmental anomalies, sig- nal jammers, and interference of all types. The digital architecture of the new receiver provides consisten- cy and precision in signal pro- cessing, while 100 fixed notch filters and eight spectrally tuned notch fil- ters work hand in hand to create a

Digital version of Trimble's 10X loran loran that not only expands the overall utility range of loran cover- age by tracking very weak signals, but also improves the repeatable accuracies of the loran answers.

A secondary benefit of Trimble's digital approach to receiver design is that only half the number of parts are required, allowing reduction in size and a major reduction in the number of things that could go wrong. According to the manufac- turer, reliability is greatly enhanced with a digital architecture.

Conrad Industries Sees

Signs Of Optimism

In Offshore Industry

Supply boats, some of which have been anchored since the early 80s, are going back to work in the off- shore drilling and exploration in- dustry in the Gulf of Mexico, ac- cording to Conrad Industries of

Morgan City. La.

The yard recently completed a renovation and liquid mud conver- sion on one vessel that is now work- ing, and a second vessel now being similarly renovated and converted will be on assignment when the con- version work is complete.

Noting optimism on the new via- bility of the offshore industry, Con- rad's CEO J. Parker Conrad said the Point Sally (nee Ada Lee Fagan) is working, and the Point Mark (nee

Grady Fagan) is scheduled for as- signment. The vessels are operated by Point Marine, Inc. of Morgan

City.

The Point Sally is 166 by 38 by 13 feet, and the Point Mark is 180 by 38 by 14 feet.

According to data compiled by

Offshore Fleet Economics (OFE) and reported in Offshore Data Ser- vices, the demand for supply vessels over 150 feet with liquid mud capa- bility is steadily increasing. During a recent week, 191 vessels out of a fleet of 203 were working for a 94 percent utilization rate. The survey conducted by OFE involved 33 com- panies situated along the Gulf Coast who own and operate support ves- sels.

Electro-Motive Awarded

USCG Engine Contract

Worth $9.2 Million

The U.S. Coast Guard has awarded a $9.2-million contract to the Electro-Motive Division (EMD) of General Motors for 32 marine propulsion engines, as part of an ongoing program to modernize ex- isting Coast Guard vessels which are used throughout the coastal waters and the Great Lakes.

Among other considerations, the

EMD propulsion units were selected because of their demonstrated reli- ability. The Coast Guard currently has eight vessels which have been repowered with EMD engines.
