The M/V Governor James Baxter

Hunt Jr. was delivered recently to the North Carolina Department of

Transportation. The 129-foot 6-inch ferry was built by Offshore Ship- building, Inc. of Palatka, Fla. The vessel was designed for river and sound service by the North Carolina

Ferry Division. Detailed design was performed by Bold Craft Engineer- ing and Offshore Shipbuilding, Inc.

The vessel was built to United

States Coast Guard Subchapter "T" requirements for small passenger vessels, as well as structural fire and damaged stability requirements.

The Governor Hunt is propelled by twin Caterpillar 3412 DITA en- gines driving propellers thru Twin

Disc MG 520 gears and 4'/2-inch

Aquamet 18 shafts. WABCO con- trols, IPS engine order telegraph and a SSI Monitoring system

Exxon Research Offers

To License Computerized

Machine Analysis System

Exxon Research and Engineering

Company of Florham Park, N.J., is offering under licensing arrange- ments a new, improved analysis sys- tem for determining changes in the mechanical performance of com- pressors, turbines, and other rotat- ing machinery. The new system uti- lizes the latest analysis equipment, and employs user-friendly computer programs with expanded diagnostic capability. The licensing package includes computer programs and as- sociated user's manual, a diagnostic manual, and training on how to use the equipment and to analyze the results.

Known as Machinery Signature

Analysis (MSA), the technology en- ables users to monitor and analyze the vibration of turbomachinery to detect and diagnose problems be- fore they become severe. This sys- tem helps plant operators avoid un- necessary shutdown, reduces main- tenance costs, and improves turn-

A Perkins model 4-336 coupled to a Lima SER emer- gency generator and a C02 firefight- ing system are installed to handle emergency situations. Electronics include two Raytheon 3500 radars, a

Raytheon F360D depth sounder and a Raytheon VHF.

In addition to offshore supply vessels and tugs, Offshore Ship- building Inc. has delivered passen- ger vessels of various types and sizes. The yard is currently rebuild- ing a 3,000-hp tug.

The MSA system uses signals from conventional vibration sensors that are mounted on the equipment.

The vibration signals are tape-re- corded, conditioned through a Fast

Fourier Transform Analyzer to sep- arate key vibratory components, and then fed into a mini-computer for data storage and processing.

The heart of the MSA system is the software that manipulates the raw data, identifies trends and changes in the characteristic vibra- tion pattern of the machinery, and presents the information for condi- tion analysis and problem diagnosis via easy-to-use, computer-generated graphics and tabulations.

All machinery process and vibra- tory data are stored in the comput- er's database. New vibratory data are automatically compared with previous data and a summary and analysis is given. The computer flags those machines that have changed since the last analysis.
