In older steam plants, even greater savings can be realized. In most cases as much as eight to ten percent savings in fuel consump- tion. Through Network 90's Com- bustion Control, Burner Manage- ment and Burner Sequencing pack- ages the ramping effect of fuel usage can be compressed under varying operation load conditions. As with diesel plants above, optimization can be achieved through vessel mod- eling.

Greater levels of marine safety have been realized through Network 90's Emergency Shut-Down and

Damage Control applications, as employed on the ARCO production platforms and the Golar Nor and

TransOcean semi-submersible pro- duction rigs. Because of the sys- tem's flexibility in logic configura- tion premature shutdowns can be prevented thereby reducing ex- pense, downtime and lost produc- tion without sacrificing safety.

Not to be overlooked, throttle control, thrust control, generator load management and integration of other auxiliary systems can easily be handled in Network 90's control schematic.

Not only can Network 90 provide immediate payback as a stand-alone control system, but more impor- tantly, Network 90 can totally inte- grate these processes into an easily managed vessel/platform optimiza- tion network. In the applications described above, Network 90 can generally pay for itself in the first year of operation. When one consid- ers the further reductions in admin- istration and preventive mainte- nance costs through an integrated approach, payback is more greatly enhanced.

Shipyard Cost Savings.

Builders as well as operators can reap the benefits of Network 90 cost reductions. Because of this system's distributed capability, modular de- sign and lack of environmental con- straints, 25 to 30 percent installa- tion cost savings have been realized.

This is accomplished through Net- work 90's reduced space require- ments for cabinetry as well as lower material and labor costs in hardwir- ing to remotely located process and termination units.

Further savings are realized through the layering of communica- tion cabling. Network 90 utilizes a twisted-pair coaxial cable as its data highway linking the various process units. By connecting various Bailey and non-Bailey systems to remotely located process units and linking them through a single set of cabling, time and expenses associated with cable pulling and installation are reduced.

Owner Operator Cost Sav- ings. As pointed out earlier, fuel savings of from as low as two per- cent to as high as 10 percent can realistically be achieved regardless of the propulsion plant or manning.

Improved equipment mainte- nance is provided through Network 90's flexible alarming and equip- ment trending analysis capability. It has been estimated that this can save up to 40 man-hours per operat- ing week.

Network 90 has obsoleted "obso- lescence." Through its modular de- sign and Bailey's unique Module

Replacement Program, system up- grade involves simply the change- out of one module or a series of modules for one with greater capa- bility. Even interface devices can be replaced without wholesale system replacements. This insures that state-of-the-art technology can al- ways be cost effectively maintained not only in newbuild but retrofits as well.

The maritime industry is not booming, but neither is it dead. This is especially true for the domestic side of that market. Bailey Controls has always been there to lead the way for marine control systems from the first automated boiler controls to the first operational integrated marine management system. We are committed to the incorporation of technology into safe and reliable control systems. We believe that the wise implemention of this type of control system can play a major role in the revitalization of the industry, and not at the expense of people.

Known as "the ship that wouldn't die," the Franklin was the most decorated vessel in U.S. naval history, and most heavily damaged ship ever to return home under her own power. Suffering direct hits from an enemy dive bomber, the aircraft carrier blazed from stem to stern, cold sea water flooded four of her eight boilers and associated Bailey controls. Afterthe surviving crewmen extinguished the fires, damaged areas were pumped out and boilers relighted. Against all odds, the

Franklin was able to steam to her home port—13,000 miles away.

Bailey end-use devices include compatible transmitters, positioners, actuators, flowmeters, and level-detection equipment.
